Hedges, Terns and Starlings

During the last week I seem to have been all over the place, doing all kinds of things. As usual we had two work parties, one on Tuesday, when we did some hedge laying near Ellingham Lake.

Hedge laying, this version is not as stock proof as traditional laying, but it retains more of the twiggy top and so should flower and fruit from this year.

The end result is what we need for a better wildlife hedge, wider, and denser than the line of saplings and in time also with some height.

On Thursday we were tidying up around the main car park, trimming back the hedges and cutting back the willows.

I would remove this laurel hedge if it was not for the large greenfinch roost that gathers in it.

In between the two work parties, on Wednesday, I had a day at the South Coast Seabird Forum discussing what can be done to bolster tern populations along the south coast. Almost everything seems to be against them, what with sea level rise, competition with gulls for the diminishing shingle banks and disturbance from human activity and predators. The one bright spot was the success of rafts at Hayling Oyster Beds and once again at Blashford, at both sites common tern nested with good productivity.

It was not really a day to be inside as it was undoubtedly the best day of the year so far, I did manage to briefly drop into Farlington Marshes before the meeting though, where I added avocet and bearded tit to my bird list for the year.

During the week the ring-billed gull continued to be seen most evenings on Ibsley Water at Blashford Lakes and both black-necked grebe remained in their usual places at each end of the lake. Walter the great white egret was seen most days and the number of brambling seem to be slowly increasing at Woodland hide.

The starling roost at Blashford has moved north and is now in reeds to the north of Mockbeggar Lane. Meanwhile I encountered another starling roost on a HIWWT reserve this week, at Lymington Reedbeds, not a huge number but the few thousand there were put on a fantastic show when watched from the causeway east of the level crossing, well worth a look if you are in the town in the late afternoon.

Just the Job

The Pop-up cafe was back and so were our splendid Blashford volunteers, for their first task of the new year. I had planned a hedge-laying task but the cold morning and brisk north-east wind caused me to rethink and look for a more sheltered work site. So we ended up clearing a patch of small willow, birch and alder that have invaded the boggy reeds at the top end of the Ivy Silt Pond. I had been meaning to do this task for a while but somehow other things kept pushing this down the list.

At the start

This is one of rather few boggy habitats we have on the reserve and it is home to a few species we do not have elsewhere, such as royal fern, bog myrtle and Sphagnum moss. I suspect all arriving there via the Dockens Water. It is amazing what five people working for a couple of hours can do!

We dead-hedged the material we cut, much quicker and less damaging than burning. Perhaps the most obvious thing int he second picture is the tall stumps, we usually cut at between knee and waist height, I know this will seem strange to many trained to cut stumps as low as possible, but I do have my reasons.

If we are working with handtools it is very difficult to cut very low to the ground, so cutting at this level is just easier. Low stumps are also hard to see when dragging cut material away so there is a trip risk, the taller stumps are easier to avoid. If I want to I can go round and cut them really low with a chainsaw once the site is clear, or I can treat them with less chance of missing any.  For some species such as birch and alder I have also found that fewer grow back at this height than if cut flush to the ground and then the remaining stump becomes a useful bit of standing deadwood.

Surprisingly on a day when visitors were complaining of the cold, it was very pleasant working int he sunshine and out of the wind and we all had to shed a layer or two to avoid overheating!

The reserve was busy with visitors all day and a good range of birds were to be seen, despite the wind. On Ibsley Water one of the black-necked grebe was close to Goosander hide for most of the day and I counted 129 pochard, a good count these days. A ring-billed gull was reported, but most of the duck were sheltering close to the northern shore.

Ivy Lake is much more sheltered and held at least one thousand wildfowl, including about 250 teal. There were also good numbers of gadwall and wigeon along with a few shoveler, pintail, mallard, coot and diving ducks. Walter the great white egret was also there during the day but seems to have found a more sheltered roost site than his usual exposed dead alder.

At the Woodland hide several brambling and a good range of other woodland species are increasingly evident. I suspect we may get good numbers later on in February and March.

New Years Day – Listers, Cakes and a Wolf Moon

As might have been expected the reserve was busy today, with birders out to start their yearlists, lots of people out for a walk and a bit of wildlife and everyone able to take advantage of a special extra Pop-up Cafe day.

I had to go around all the hides to take in last year’s logbooks and put out the new ones, so I took advantage of walking to whole reserve and starting my own yearlist. By the time I had opened up all the hides I was already on 53 species of birds and 3 species of mammals. I actually saw Walter, our great white egret when I was opening the Centre as he flew over the car park, perhaps a good thing as he was not at his usual roost at dusk, probably because of the cold wind that got up later in the day. Two pairs of mandarin duck on Ivy Lake were a little unexpected and 96 pintail on Ibsley Water was the most I have seen this winter.

I still had to go to Goosander and Lapwing hides and my trip there saw me add black-necked grebe, in fact there were two, one distantly near Gull Island and the other quite close to the hide. A water pipit at Lapwing hide was also good to see.

It was not all about the birds though I saw two flowering plants in bloom, primrose – living up to its name of “prime rose” or first flower.

The second was a small clump of the undoubtedly planted snowdrop beside the car park, although the flowers of these were not quite open yet.

Later in the day I managed to add some more bird species to my list, including a fine male brambling, the ring-billed gull, a first winter Caspian gull and an adult Mediterranean gull, meaning that I ended with 73 species. Not a bad total as I always think anything over 70 in a day at Blashford is good. I missed at least ten species that others saw or I know were there, so I could have got 80 with a very fair wind, maybe one day.

Closing up the Moon was very large and full in the sky, apparently this is the day when the full Moon is the closest to Earth that it will be in the whole of 2018. I am also told it was a “Wolf Moon” it seems this is the first full Moon of the New Year. Whatever you call it, it was certainly very striking.

Driving home I was surprised to see lots of Winter moth flying in the headlight beams as I drove down Ellingham Drove, my first moths of the year.

A Cold and Frosty Morning

Despite the chill, seven volunteers turned out today to do a dead hedging task at Blashford Lakes. I am a great fan of the dead hedge, when we are scrub cutting, or coppicing or just dealing lop and top it provides a great way to clear the branches without the damage caused by burning. Conservationists are great at leaving log piles for invertebrates, often forgetting that the smaller branches and twigs are home to even more species. In addition the dense tangle of a dead hedge provides cover for nesting birds, hibernating insects and also makes a good barrier. We use them as shelter to promote bramble, both as barrier features and habitat in its own right.

Out on the reserve on Ibsley Water the black-necked grebe was still present as were both pink-footed geese, although the juvenile looks very unwell. I counted 118 pochard, my largest count for some years, although I missed the goosander roost, a disappointment as I expect there are well over 100 now.  Near the Centre and at the Woodland hide there were a few brambling and one or two lesser redpoll.

Dusk saw a somewhat reduced number of starling coming to roost, although they gave a good show thanks to being attacked by a peregrine. The gull roost included the regular ring-billed gull, although it seems there has been another bird seen recently, although I don’t think both have been seen on the same evening. “Walter” our great white egret was back on his dead alder roost on Ivy Lake near the cormorant roost, but there still seems to be no sign of a bittern yet.

I got an almost equally poor record shot of the black-necked grebe the other day as well, poor but still the best I have managed!

It will close with a last shot of the Ivy Silt Pond with almost perfect reflections in the calm chill of the morning as I opened up the hides.

Don’t forget the Pop-up cafe will be in again on New Years Day, see you there!

A Fishlake Wander, Recent sightings and Festive Opening

Work at the new Trust reserve at Fishlake Meadows is picking up, with the fencelines being cut out and plans being made for the start of willow coppicing, both to maintain some of the low scrub and to open up some new views across the reserve. As part of this planning process we were out on site at the start of the week, luckily we picked a good day.

On our wandering in some of the damp fields we encountered a large number of Cetti’s warbler, the reserve has large areas of almost perfect habitat for them. We also flushed a fair few snipe including one jack snipe. Perhaps our most surprising sighting was of 2 hawfinch perched in a small tree near a flock of fieldfare. There has been a once in a lifetime invasion of hawfinches this winter with many thousands arriving from the continent. These two were probably some of these immigrants rather than local birds, but with the New Forest being the UK hotspot for the species they could have been more local.

Around the drier margins and especially along the canal path there are still many live poplars and quiet a few of them have a festive bunch or two of mistletoe high in their branches.

Meanwhile at Blashford Lakes latest reports are that the ring-billed gull is now being seen regularly in the gull roost on Ibsley Water as is the first winter Caspian gull, with a 2nd winter bird also reported recently, the roost also includes 2 Mediterranean gull. The starlings have been putting on quite show, with some estimates of up to 50000 birds coming into roost, usually just to the west of Ibsley water so seen from the hill at the back of the main car park. On Ibsley Water itself there have been up to 104 goosander roosting, 14 goldeneye and a single black-necked grebe. At least one of the pink-footed geese can be seen on and off with the greylag. There continue to be something like 90 pochard and 25-30 pintail as well.

On Ivy Lake “Walter” the great white egret is being seen fairly regularly and was joined by a second bird the other day. From Ivy North hide water rail and Cetti’s warbler are regular, although we have yet to get a report of a bittern this winter. The Woodland hide has one or two brambling and lesser redpoll as well as the occasional and less desirable report of brown rat.

CHRISTMAS OPENING: We will be open as usual over Christmas apart from Christmas Day itself when we will be closed. In addition on New Years Day we will have the Pop-up Café again in the Centre, so you can start your birdlist for the year and get a hot cup of something and some excellent homemade cakes.

 

Early Birds

I decided to get on site early on Sunday so that I could count the goosander as they left their roost on Ibsley Water. I managed to get my best count of the season so far, 72 birds. I also saw a group of 7 drake goldeneye, all displaying to a single female. Other species included 12 pintail and the usual range of ducks.

Walking back to the Centre I saw at least 3 chiffchaff, a firecrest and 2 hawfinch. The last are occasionally recorded at Blashford, almost always in ash and field maple trees close to Ellingham Drove, which is where these were. This winter has seen an unprecedented influx of this species, with flocks being seen in lots of places and will probably be my best chance to get them on my garden list. In fact overall it loos like  a good finch winter, with numbers of brambling and redpoll also in evidence.

I was working with volunteers clearing a ride along one of the butterfly transects and so saw rather few birds after my early excursion. The pink-footed goose was again in the greylag flock and a single dunlin was feeding out on the islands in Ibsley Water. At dusk I saw “Walter” the great white egret roosting in his favourite dead alder beside Ivy Lake.

Cake and Colours

A fine Blashford day and better still one with cake, because we hosted the Pop-up Café once again today. The reserve was fairly busy, both with visitors and birds. At opening up time Ivy Lake was busy with ducks, nothing unusual, but a good mix of species.

The trees are in particularly good colour just now, with the oak just turning, joining the beech, hazel, willows and others. Some hazel are still completely green while others are in their autumn glory.

Although there are few on the reserve, the guelder rose draws attention at this time of year thanks to very bright leaves.

Field maple, like all the Acers, has very good autumn colour, although most of their leaves seem already to have fallen at Blashford.

Not all the colour comes from leaves though, I know Tracy posted a picture of it on Friday but I cannot resist another one of the cobalt crust fungus.

The colour is amazing! It seems it is uncommon and mostly found on ash twigs and branches, at Blashford it is on rotting willow branches lying on the ground in deep shade.

Out on the reserve both the water pipit and pink-footed goose were on show at Tern hide on and off throughout the day. Over 30 goosander were present well before dusk and 3000 or so starling gave a rather brief display before going to roost rather earlier than I had expected.  Three Cetti’s warbler were singing around Ivy Lake and a fourth was calling beside Lapwing hide. At Woodland hide a redpoll, a couple of brambling and a firecrest were all reported and a woodcock was seen in the willows near the Centre car park. At dusk on Ivy Lake, Walter our regular great white egret was again roosting in his favourite dead alder beside the cormorant roost.

Wednesday 15th November – A Little Report

A “Little Report” because there is not much to report from today. The reserve was busy with a large group visiting from Christchurch U3A, but the bird news was fairly unremarkable.

Opening Tern hide I heard the or at least a water pipit calling, but could not see it. The lake had the now usual gathering of pochard. My count of 96 yesterday was by some margin the largest I have seen for a good while, there was a time when they were common at the lakes, with flocks into several hundred. Over the last few years pochard numbers have declined, not just here but right across Europe. Over the last 25 years there has been a 67% decline in wintering pochard in the UK. There are many possible reasons for this. They particularly like eating stoneworts, aquatic plants that grow well in oligotrophic (low nutrient) lakes, newly flooded gravel pits usually have very few nutrients and so are very good for them. However over time lakes acquire nutrients form many sources becoming less suitable for stoneworts and pochard. This is probably one of the main reasons for the decline at Blashford.

It might be expected that gravel pits in lowland England would gain nutrients, weed will grow and die, birds will import droppings and fish will mobilise sediments as well as adding their own contribution. In addition the rain is known to be contaminated with nitrogen which it picks up from the atmosphere, where we have added additional nitrous oxide to that naturally present. Recent reports by researchers at the British Geological Survey have highlighted that nitrogen fertilizers have leached their way down into the groundwater and will be coming out for decades to come.  These sources of nutrients do not include straight forward pollution by industry, sewerage etc. The increase in nutrients is impacting both natural and man-made waters and means that we are faced with a future where most lakes, at least in lowlands will be eutrophic, that is nutrient rich. Ultimately such lakes are likely to be dominated by algae, with little higher plant growth upon which most of our wildfowl depend.

Unfortunately for the pochard it seems that it is not just increasingly unsuitable waters that are against them. It has long been known that wintering flocks in the UK hold more drakes than ducks. Last winter wildfowl counters across Europe were asked to provide the sex ratio of the flocks they counted. This showed that across the whole of Europe the proportion of drakes in flocks had risen from 61% in 1989-90 season to 70% in 2016. The proportion of drakes being higher in northern Europe with more female wintering in southern Europe. It might be expected that females would suffer higher mortality at nesting as they nest on the ground where they are vulnerable to predators. However this is probably not the only reason fro the discrepancy. By wintering in southern Europe where hunting is more popular they are probably more often shot, but worse still they are especially vulnerable to ingesting shot and are more likely to do so in areas where there is more shooting. The paper outlining this research will be available soon at http://www.wwt.org.uk/conservation/saving-wetlands-and-wildlife/publications/wildfowl/ .

Anyway back to the day’s news, at the Woodland hide brambling was again seen and overhead a few redpoll could be heard in the siskin flock, things are looking good for large finch flocks later on. Towards dusk heading out to lock up I heard a firecrest again near the car park and this time also saw it, my first one seen this winter at Blashford, although  one was reported the other day from the main car park. On Ivy Lake Walter the great white egret was again at his roost in the dead alder with 150 or so cormorant also roosting in the trees around the lake.

I did have one non-bird sighting of interest, a common darter dragonfly still on the wing, my first for ten days or so, each year I hope to beat my latest dragonfly date of 19th November, which I have managed three times, I don’t think this is going to be the year though, with so few still flying.

Some Bird Sightings

A few sightings from the reserve today, mostly from Ibsley Water. When I opened up the Tern hide there were 4 pintail (3 drakes), 3 green sandpiper (the most I have seen so far this season) and a drake shelduck.  I dropped in there briefly at lunchtime and saw a water pipit just in front of the hide and did not see the juvenile pink-footed goose which was hiding in a large flock of greylag.

Elsewhere there were reports of one or two brambling from near the Centre and Woodland hide.

At closing time there was a first winter Caspian gull in the large gull roost on Ibsley Water, I estimated about 7000 lesser black-backed gull. There was also a gathering of starling, still in the 3000+ range, so enough to be a decent flock but not a really spectacular gathering yet.

As it was almost dark, I could just make out “Walter” our returning great white egret roosting in his favourite dead alder tree beside Ivy Lake.

Some Seasonal Firsts!

Things are getting increasingly wintery, there was a frost on the grass this morning, 2 brambling were visiting the feeder by the car park and the Pop-up Café returned! Although the brambling have been around for a few day today was the first time that I had seen them, in fact I saw a few things for the first time this season today, I caught up with the pink-footed goose and saw a very smart first winter Caspian gull at dusk. Other firsts were mostly cake!

The Pop-up Café is once again being operated by Walking Picnics, just a sit was last winter and will be at Blashford on the first and third Sunday of each month and New Years Day.

There was no sign of the lesser scaup today as far as I know, possibly put off by fireworks last night but the ferruginous duck was spotted, distantly by the northern shore of Ibsley Water, somehow I avoided it when I counted the pochard flock in that very area, there were 66 by the way, quite  a lot by the standard of recent years.

Elsewhere a couple of chiffchaff and a raven flying over and a few goldeneye and goosander on Ibsley Water were the best I could find. The sun did tempt out a few red admiral butterflies but I saw no dragonflies, which surprised me, as the sun was quiet warm.

All of the above actually happened in the afternoon as my morning was spent with the first Sunday of the month volunteers widening the margins of the path beside Ellingham Lake to provide more sheltered areas for insects and, hopefully reduce the tendency for brambles to overhang the path next summer. Increasing the area of transition between the path and the scrub by having  a margin of grass and herb species should provide habitat for butterflies and other insect next year, in effect we have made a miniature woodland ride. As ever the team did a load of work even though we only worked for a couple of hours or so.
