Birds, Birds, Birds

Blashford Lakes are a great place to see lots of birds. Both Ibsley Water and Ivy Lake have large numbers of duck at present with each often having over one thousand wigeon on most days recently.

There are also hundreds of pintail on Ibsley Water, they have been attracted up the Avon Valley along with a lot of the wigeon due to the flooding of the fields. These ducks tend to spend the day resting on the open water, only going out to feed in the valley after dark. By contrast most of the gadwall will be found feeding on the lakes during the day, with fewer flying out at dusk.

Ivy Lake is home to a large cormorant roost, these fly in at dusk to perch high in the trees around the lake shore, so far this winter I have managed to count only about 150 birds, but this roost can get to over 200.

For really large numbers of birds the time to visit is just before dusk, if you stand on the viewpoint at the back of the Main Car Park, from where you can see several thousand gulls fly in to roost on the water and tens of thousands of starling. Last evening the starling roosted in two locations, most to the north of the lake, but several thousand also to the west.

The birds were making impressive shapes in the air as they were being chased by at least one peregrine and we also saw a marsh harrier fly past. We could also see goosander flying in to roost on the lake and as it got dark a load of cackling greylag flew in to spend the night on the water.

The reserve is not all about birds though and as I locked up in the morning there were three roe deer feeding in the reeds just beside Ivy North Hide.

If you are visiting, I can now report that the Main Car park is open as usual as the flooding has now receded.

 

What a difference a day makes!

After a gorgeously sunny Christmas Day yesterday, today saw the return of the rain and I got soaked opening up the hides – needless to say the reserve has been very quiet today! Even the wildlife decided to stay in the warm and dry – we have been keeping an eye on the Tawny Owl box as something has definitely moved in and made itself a very dry and cosy home out of oak leaves and soft rush. Although not the owl we had been hoping for, it is still very nice to see a grey squirrel up close on camera, although you can’t see much when it hunkers down inside its nest:

IMG_2195

Last week we realised one had stashed food in the box as we noticed it rummaging through the wood chip that had been put in the bottom – clearly it decided with all the rain we’ve been having this was a good spot, came back and made some home improvements. This morning I watched it look out the hole a few times before it decided it was better off back in bed:

Wet grey days are definitely for catching up with the blog, and this one may turn out to be quite long as I am two Young Naturalists sessions behind, one of which was our November residential at the Countryside Education Trust’s Home Farm in Beaulieu…

Unfortunately the weather was not quite on our side then either, although we were able to dodge most of the showers. We began on the Friday night with an excellent talk by Steve Tonkin about the night sky – sadly it was too cloudy to head outside for any observing so we will have to invite Steve again another evening, but the group enjoyed the talk and asked some excellent questions that definitely kept Steve on his toes.

On Saturday morning we headed to Rans Wood, just outside Beaulieu, to meet Sally Mitchell from Wild Heritage for a fungi walk. We didn’t have to stray too far from the car park and were rewarded with over thirty species which was great for late Autumn. Before heading off Sally tested the group’s current fungi knowledge with an identification activity – they knew a few edible and inedible species and were also very good at erring on the side of caution with those they weren’t sure about.

Fungi foray

Testing our knowledge

Fungi is not my strong point so it was brilliant to go looking with someone able to identify what we saw and also be so enthusiastic about it. Sally also has permission from Forestry England to pick the fungi for identification purposes (not to eat as there is a no picking ban for this in the Forest), so we were able to study some close up and take a closer look at the gills or pores. We also used mirrors to look under some, including the Amethyst deceiver, so we could see underneath without picking.

We did quite a lot of sniffing! Here are some of the different species we found – I think my favourites were the Amethyst deceivers, the bright Yellow club and looking at the tubular pores inside the Beefsteak fungus:

We also paused to have a go at ‘creating’ a Fly agaric – sadly we were unable to find any – using a balloon and a tissue. The tissue was held over the balloon and sprayed with water to make it damp. When air was blown into the balloon, the balloon became larger and the tissue broke up into smaller pieces as this happened, to create the speckled effect of white spots seen on the Fly agaric fungus.

We also found a huge oak tree so decided to see how many Young Naturalists could fit around it:

Hugging a very large oak tree!

After thanking Sally we headed to Hatchet Pond and had lunch with the Mute swans, Black-headed gulls and donkeys.

We then spent the afternoon at Roydon Woods, another Hampshire and Isle of Wight Wildlife Trust nature reserve, and tested the fungi identification skills learnt that morning, keeping our fingers crossed for a glimpse of a Goshawk whilst we wandered. We last visited the reserve in the Spring, when the woodland floor had been carpeted in bluebells and other Spring flowers, so it was nice to return in the Autumn.

Some of the group were also lucky enough to spot a Goshawk fly past, but only because we had stopped to wait for others to catch up and it flew past behind them. A lucky encounter!

On the Sunday the group enjoyed a farm feed session first thing with Education Officer Steve whilst Michelle and I tidied and cleaned Home Farm ready for our departure. They love doing this as they can get up close to many of the animals and help out with the feeding:

We then visited the New Forest Wildlife Park and were joined by another couple of the group who had been unable to stay for the weekend. We had arranged a guided tour with one of the park’s education team and Laila was brilliant – I think she enjoyed a slightly older audience to usual and the group were great at engaging in conversation about the wildlife and different conservation projects. I was impressed by how much they knew. We got caught in a couple of heavy showers whilst we were there which made taking photos a bit difficult, but here are a few, the harvest mice were popular…

We had a brilliant weekend so although it was a while ago now, would like to thank Steve for the astronomy session, Sally for her fungi knowledge, Steve for the farm feed session and Laila for the brilliant tour around the wildlife park. We also couldn’t run residentials without volunteer support so would like to say a huge thank you to Geoff, Nigel and Michelle for giving up their weekends to join us and help with all the cooking, cleaning, minibus driving and evening entertainment (we had a quiz Saturday night which was hilarious)…

Sticking with the Young Naturalists theme, on Saturday we ventured over to Poole for a boat trip with Birds of Poole Harbour. The group had been fortunate to win the boat trip as their prize for coming first in the bird trail here at Blashford back in May, and we were able to open it up to other group members who hadn’t been able to join us on the day and turn it into our December session.

It was rather cold and wet at times, and we saw a lot of rainbows whilst out in the harbour, but also managed at least 26 species of bird including Red-breasted merganser, Shag, Great black-backed gull, Great crested grebe, Great northern diver, Brent goose, Gadwall, Avocet, Shelduck, Teal, Shoveler, Cormorant, Black-tailed godwit, Grey heron, Oystercatcher, Grey plover, Dunlin, Knot, Little egret, Wood pigeon, Sandwich tern, Goldeneye, Starling, Carrion crow, Spoonbill (very distant!) and Curlew.

We had some nice views of Brownsea Island and the lagoon…

Thanks for reading! Here’s a sunnier photo taken just up the road at Ibsley when I was passing yesterday morning as a reward for getting to the end, hopefully it will stop raining again soon!

Substitutes and Declines

It was feeling very spring-like today, I got very warm as I worked with the volunteers felling some grey alder beside the path to Lapwing Hide. These trees were planted as a “substitute” for native alder, which is not a hard tree to source, when the restoration planting was done after the gravel working ceased. Sadly truly native trees are not always specified in planting schemes, even when they are supposedly done for nature conservation and even when they are, substitutes are often allowed. Often even if the tree species is native they are not from a UK source, importing trees has brought us several diseases that have significantly impacted upon native woodland. These imports are also often adapted to a different climate so will flower or leaf earlier out of sync with native insects. Let’s have more native trees that are really native, ideally grown from the seed of trees as local to the planting site as possible.

wild daffodil

Wild daffodil just coming into flower, a good indicator of remaining ancient woodland at Blashford Lakes.

Having said all this planting trees is an often seriously over rated activity, if they establish well we end up with secondary woodland that will not be more than a pale shadow of an ancient woodland in even a thousand years. The best way to extend woodland cover is to allow existing ancient woods to grow outwards, letting them seed into neighbouring open ground, something that will happen naturally in most places if grazing or mowing are stopped. This way we will get locally adapted trees establishing where they will do best and other species can move out from the old wood into the new. It will also serve to buffer the older woodland and reduce the distance to the nearest neighbouring wood. I am prepared to make an exception for hedges though, so many of these have been lost that replanting is the only practical way to get them back, but the need for locally plant stock remains important.

There has been a good bit of coverage of the severe global decline in insect numbers in the media over the last few days and it is very alarming. A series of studies are now coming to very similar conclusions and these are that insects are in trouble globally with significant declines not just in developed western Europe but in tropical forests as well. Insects may be small but their abundance and diversity mean they are vital to the effective functioning of almost all terrestrial ecosystems. They are predators and prey, decomposers, pollinators and grazers, in fact they are almost everywhere and everywhere they are, they perform essential functions. I have run a moth trap for many years monitoring the species caught before releasing them and I can attest to a great drop in numbers over the years, I see as many species but none in great abundance as I used to.

Pale brindled beauty, a typical late winter species, there were two in the trap last night.

Over the last few weeks things have been a bit hectic on the reserve with work going on all over the place, the new pond is being dug behind the Education Centre and preparations continuing for the installation of the new Tern hide next month. We are doing our best to keep the reserve up and running in the meantime, but there will be occasional interruptions to normal service, such as temporary closure of the main car park or limitations on the use of parts of the car parks.

Out on the reserve two bittern have been seen a number of times recently at Ivy North hide as have two great white egret. I am especially keen to try to record the last sighting of “Walter” our colour-ringed great white egret, he usually heads off back to France around this time of year so any definite sightings gratefully received. At the weekend an otter was seen at Ivy North hide and this morning I have very, very, brief views of one near Ivy South hide, so it is well worth keeping an eye out.

All Change

After a cold and snowy end to last week,  Sunday saw me arriving to find almost the whole of Ibsley Water frozen over and Ivy Lake completely so.

Things actually started to thaw during the day on Sunday, so that by the end of the day there was more open water, at least on Ibsley Water.

goosander flock preening

The cold resulted in a typical increase in the number of common gull in the roost, with over 400 reported and, more excitingly, the return of the ring-billed gull, probably it had come in with the common gull influx, but where has it been?

Even at dusk  on yesterday Ivy Lake was still frozen over and this seemed to put off the cormorant roosting flock, instead of the usual 150 or more birds there were just two! Others did fly in and around the trees but headed off elsewhere. A single great white egret, probably “Walter” roosted in the trees, but away from the two cormorant.

Today was quite different, mild and wet, a combination of snow melt and rain resulted in the Dockens Water flooding through the alder carr and into Ivy Lake, probably to the great relief of the bittern which was back in the reedmace at Ivy North Hide as I locked up this evening.

bittern

I am pretty confident that every sighting of bittern that I have had this winter has been of the same bird, as have been all the pictures I have seen. On a couple of occasions I have seen threat behaviour that I would usually associate with there being a second nearby, but have never seen another bird. So reports of two seen on Friday were interesting, although the second bird could just have been displaced by the cold as they often are when lakes freeze. However today I see that two were seen in early January, so perhaps there really have been two all along! As they are territorial it may just be that the second is usually too far from the hide for us to see it, there is a good bit of reedbed off the west of the Ivy North Hide where it would be very difficult to see a lurking bittern.

By dusk this evening it was quite hard to see very much in any case, as the mist descended over the lakes.

13th January – Great White and Yellow-browed

Another busy day on the reserve with the yellow-browed warbler performing pretty well throughout the day and drawing a steady flow of admirers to its favoured area neat Ivy South hide. It was not the only warbler on show though, there were Cetti’s warbler at Ivy North hide and at the silt pond neat Ivy South hide. Chiffchaff have been particularly frequent this winter and today I saw them near Ivy South hide, on the approach to Goosander hide and near Lapwing hide.

In the brief bit of sunshine we enjoyed around midday I went to have a quick practice with the new camera, these are some of the results.

Although finch numbers at the Woodland hide are not large, they are increasing with siskin leading the charge and also an occasional redpoll.

At dusk there were at least 187 cormorant roosting in the trees beside Ivy Lake, which I photographed earlier in the day when there was more light.

As Jim mentioned yesterday the car park nearest the Education Centre will be completely closed from tomorrow morning for at least the next week, this will mean no access along the track to the Centre, either for vehicles or pedestrians, you can still walk to the Centre using the footpath to the left of the track, always the safest route. The work is aimed at  levelling the car park surface to reduce the large puddles that are sometimes an unwelcome feature.

Further works are in the pipeline, so please keep an eye on things here to keep up to date with events.

The Best of Blashford

The second Pop-up Cafe of the winter today and, thankfully, the weather was a great deal better than the damp day we had at the start of the month. The reserve was busy and there was a good deal to see from most points, for most of the day.

Opening up Tern hide I saw a water pipit, although my first notable birds were at the main gate, where there was a fieldfare with a couple of redwing and a pair of bullfinch. 

I then spent a couple of hours attending to various tasks about the office before getting out to Lapwing and Goosander hides. We have done quite a bit of work on and beside the paths in this area with the object of both maintaining good access and making the walk more interesting for visitors and wildlife. To this end we have been scraping back the path edges and thinning the small trees to make clearings, increase the light and open up some views over the reeds. This work should also benefit insects and the reptiles that use this area, so we have been making sunny sheltered clearings and have dug one new sandy bank for solitary bees.

Up at Lapwing hide I was surprised to see several hundred large gulls, it was only late morning, so way to early for a roost gathering. I noticed the other day that there were  a lot of large gulls on the lake very early in the day. I suspect there are two possible explanations, either they are feeding very nearby and dropping in and out between bouts of feeding, or they have found somewhere with so much food that they are getting their fill in just a couple of hours. Looking through the gulls I saw the Caspian gull found yesterday, it is a “textbook” first winter bird, which always helps with these potentially difficult to identify birds.

At Goosander hide on the way back there were 2 green sandpiper and a dunlin, the latter flushed from the Long Spit in the company of a snipe by a peregrine. I took the long way back as I wanted to investigate some tyre tracks I had noticed on the Lichen Heath last Monday. Hidden away on the far side of the water treatment works I found out where they had been heading and why, a heap of fly-tipped material. I suspect dumped in the rain last Saturday, since it must have been in the day and when there were not many people around. We are certainly welcoming donations at the moment, but not this kind! It goes without saying that if you are on the reserve and ever see anything suspicious like this please make a note of what you safely can and let us know.

We always welcome donations of course, but at present we are trying to raise money to make a number of improvements to the reserve. The largest of these is the replacement of the Tern hide, the existing hide is suffering a bit and we recently won a grant to replace it, if we can raise the rest of the funds, to find out how you can help us see The Blashford Appeal

On my way back from a bird food buying trip I dropped in at Tern hide and saw 3 great white egret in the distance flying north up the Avon valley, I assume our regulars, but who knows? After another spell in the office I got out again in the late afternoon where there was a marsh harrier visible in the distance. Out on the lake the numbers of gulls had increased a lot and were more than I have seen this winter so far by some margin. I found the ring-billed gull deep in the flock, but unfortunately had to take off my glasses and when I looked back I could not find it again.

The Pop-up Cafe had done well, they will be back with more excellent cake on the first Sunday of December, so if you missed them today you could come then, or on the 16th of December, or both and New Year’s Day as well. You can also get a range of Wildlife Trust gifts and Christmas cards.

Locking up I saw 2 great white egret as usual at Ivy North hide, there were also at least 160 cormorant roosting in the trees and at least 161 tufted duck on the water.

It had felt like a good day almost all round, fly-tipping excepted. The reserve was busy with a range of people watching wildlife, from keen rarity hunters to families enjoying the nuthatch and the fine male sparrowhawk perched at the Woodland hide and there was cake too. Blashford Lakes is fortunate to have elements that appeal to a wide audience, we have popular events for ages from toddlers onward and different parts of the reserve that offer highlights for all types of wildlife seekers. Hopefully the reserve can continue to enthuse a wide and growing audience, our wildlife needs all the supporters it can get!

A Marvellous Day

The first Sunday of the month is volunteer task day and this morning we were continuing work on the path between Goosander and Lapwing hide. The path is being trimmed back and the gravel surface cleaned of grass and other growth,. In addition we are opening up sheltered clearings along the path to increase interest. At one point we are making a solitary bee nesting bank, it is always worth making use of suitable ground for these kind of features which can be quiet rare.

Out on the reserve there were lots of visitors enjoying the cool sunshine. There were birds to see to, especially from Goosander hide where the feeding frenzy is still in full swing. There were 50 or more grey heron, several little egret, both great white egret and lots of cormorant, with gulls and grebes there to mop up the small fry.

The ferrunginous duck seems to have departed, probably for Kingfisher Lake and the wood sandpiper also appears to have left after a rather long stay. There was still a common sandpiper and at least 2 green sandpiper though and a rather unexpected redshank, not a bird we see much other than in spring and summer at Blashford.

Elsewhere there were 2 pintail on Ivy Lake along with 6 wigeon and I saw at least 300 coot on Rockford Lake. In the willows around the reserve there were good numbers of chiffchaff, but no other small migrants that I could locate. A few swallow were passing through, including at least one rather late adult, most at this time are juveniles. First thing this morning there were 60 or so house martin over Ibsley Water although I saw none later in the day.

Locking up there was a considerable gull roost developing and I noticed that there were a lot of very dark backed individuals amongst the lesser black-backed gull flock, a much higher percentage than we see in the winter, an indication of birds from further north and east in Europe passing through.

The sunshine brought out a few butterflies and I saw a good few speckled wood and several small copper around the reserve. The cool night was not the best for moths but the trap did contain one of my favourite species, a merveille du jour.

Merveille du Jour

Other moths were red-line Quaker, large yellow underwing, lunar underwing, beaded chestnut, black rustic and deep-brown dart.

 

September’s End

Another fine day although with more of an autumnal feel that yesterday. There was still mist over the lakes as I opened the hides, from Tern hide the highlight was the unringed great white egret flying past the hide, heading south.

I made the most of the cooler conditions to go and do some path trimming, in places the bramble growth has pushed the path almost completely off the gravel surface. I was working near the southern end of Ellingham Lake  and the hedge there has some large ivy growths, some of it now flowering and on these I saw a few of the ivy bee Colletes hederae. This is quite large for a solitary bee and flying so late in the season is very obvious, so it seems extraordinary that it was only described as new to science in 1993, since when it has been found over much of Europe. It was first found in the UK in Dorset in 2001 and has now spread as far north as Norfolk.

In the late afternoon I went over to Goosander and Lapwing hides. In the reedbed and willows there were a few chiffchaff but no other migrants. From Lapwing hide I saw 2 green sandpiper and at least 1 common sandpiper. The screens overlooking the silt pond behind Lapwing hide proved worth a look with 2 mandarin and 2 snipe on show and some bullfinch in the willows.

At Goosander hide there has been a feeding frenzy going on for many days now. The cormorant seem to have got a large shoal of small carp hemmed in the bay near the hide and they are attracting everything that can swallow a small fish. There were the cormorant of course along with little egret, a great white egret (Walter this time), grey heron, great crested grebe, little grebe, black-headed gull and even mallard. The mallard and gulls are mostly steeling dropped fish, but a lot of the cormorant seem not to be bothering to eat everything they catch. Sometimes the cormorant are coming up with large perch or even pike, these are also in on the hunt for small carp, but run the risk of becoming a meal themselves in the process.

The cormorant dive for the fish which are driven into the weedy shallows in an attempt to escape, where they then run into the line of heron and egret.

Finally, as I locked up the tern hide right at the end of the day I was delighted to see the reported wood sandpiper just in front of the hide. It was a juvenile, with fresh yellowish spangled feathers looking very splendid in the golden glow of the setting sun. To add to the scene the grey phalarope flew in and landed some 100m away, despite trying I could not see the juvenile garganey that was also seen earlier, but tomorrow is another day.

 

Birds, Beetles and Butterflies (and a bit more besides)

We are slipping into autumn, despite the weather remaining warm the signs are everywhere. Berries are ripening and birds are on the move. Over the last few days there have been between 500 and 1000 house martin over Ibsley Water, gathering before migrating south. On Ivy Lake numbers of winter wildfowl are starting to rise, at least 12 wigeon and 18 shoveler were there on Sunday and last week 3 pintail dropped in. In fact overall numbers of wildfowl are very high for the time of year, probably due to good weed growth.

Any visitor to Ibsley Water recently cannot have failed to miss the large numbers of cormorant and heron. They are feeding on the huge numbers of small common carp, a fantastic spectacle, but a sign of problems ahead. Such large numbers of small carp will grow into a very large population of medium sized fish which are likely to largely eliminate the weed and eventually most of the food for wildfowl.

Another very obvious feature at present is the lace-like leaves of the alders, they have been eaten away to skeletons.

The alder leaf beetles that are responsible are a striking metallic blue and were considered as an extinct species in the UK until just a few years ago, however their status has changed dramatically in the last few years and they are now not just present but super abundant. They seem to be everywhere at the moment and almost every alder leaf has been eaten away and they seem to have been eating hazel and even birch as well. Quiet why they have undergone such an extreme change in fortunes is something of a mystery.

We are now heading into autumn and the moth trap is starting to catch species typical of the season, perhaps none more so than the aptly named autumnal rustic.

Another autumn favourite of mine is the intricately marked feathered gothic.

The males use their feathered antennae to test the air for female pheromones, in effect using them to smell.

The main butterfly on the wing at present is speckled wood and they are very abundant this year, they are one of the few species that you can see throughout the season as they have a series of overlapping broods. Sometimes the first are on the wing before the end of March ans they can still be flying in November.

Autumn is also the fungi, actually they are to be found all year but many species are most abundant at this time of the year. When we were working today we came across a bright yellow patch on a log near the Woodland hide, but although many of the logs in that are are covered in fungi, this was not a fungus, but a slime mould called troll butter.

For those that like to venture up to the Lapwing hide in the winter or spring I have good news. The need to take the long way round or risk getting wet feet when the route through the reedbed floods will soon be a thing of the past, we are having a boardwalk constructed!

The White Stuff

A Red Letter Day for Fishlake Meadows today, we finally have some cattle on site! We had hoped they would be on much earlier and next year I am sure we will. They will be grazing in Ashley Meadow for the next few weeks, hopefully helping us to maintain the rich fen habitat.

English White cattle on Ashley Meadow

British White cattle on Ashley Meadow

As we were unable to graze the meadow earlier in the year we did take a hay cut from about half of the field.

Ashley Meadow

The intention is to maintain a mix of tall and slightly shorter herbage with very few trees and shrubs. Such habitats are very rich in plants and as a result invertebrates. Mowing certainly can deliver this, but the act of mowing is rather dramatic, eliminating large areas of habitat at a stroke, by contrast grazing achieves a similar result but at a more gradual pace. Gazing animals will also favour some areas and species over others so the variability in height, what is known as the “structure” of the grassland will be greater.

When I was in Ashley Meadow preparing for the arrival of the cattle today I saw a good range of species including several very smart small copper.

There was a very interesting article in a recent issue of British Wildlife magazine which highlighted the effects of different grassland management regimes on spider populations and species. I have not managed to identify the one below yet, but I saw it lurking on a flower waiting for an unwary insect to be lured in.

spider

crab spider on fleabane flower

When looking at grassland management there are many considerations, should it be mown or grazed,or both, most hayfields are cut for the hay crop and then grazed later in the season. Traditional hay meadows were cut around or just after mid-summer and this favoured plants that set seed by this time like yellow rattle or which spread vegetatively. Modern grass cropping by silage making produces a much larger grass crop but the grassland is more or less a mono-culture, the land may be green but it is certainly not pleasant as far as most wildlife is concerned.

Once the cutting regime is settled there is grazing to consider, but not all animals graze in the same way, sheep and horses cut the grass short using their teeth, cattle rip the grass in tufts using their tongue to gather each bunch. The resulting grassland will look very different and be home to very different wildlife. Timing of grazing will also make a big difference, mid-late summer grazing tends to produce the most diverse flora, but this will vary with location and ground type.

Lastly different breed of animals will graze in different ways, our cattle at Fishlake are British Whites, a traditional bred that will eat grass but also likes to mix in some rougher sedge and other herbage as well as some tree leaves and twigs, ideal for a site such as Fishlake Meadows.

It was not only a white themed day at Fishlake, as I locked up at Blashford Lakes the view from Tern hide was filled with birds, in particular 13 brilliant white little egret and 2 great white egret.

herons egrets and cormorants

egrets, herons and cormorants

Ibsley Water has been attracting huge numbers of fish eating birds recently, with up to 300 cormorant, over 100 grey heron and the egrets, although I have failed to see them there have also been 2 cattle egret seen.

Ivy Lake has also produced a few notable records int he last few days, yesterday a bittern was photographed flying past Ivy South hide, far and away our earliest reserve record, but with the British population doing much better these days perhaps something we will get used to as young birds disperse. There have also been a few notable ducks, yesterday a juvenile garganey and today 4 wigeon , 3 pintail and a few shoveler as well as good numbers of gadwall and a dozen or so teal.
