Caught on Camera

It has been a busy week at Blashford Lakes with volunteer work parties on four days, despite unpromising weather we actually got a lot done. On Sunday we repaired some damaged sections of the boardwalk, Tuesday saw us felling some non-native grey alder trees, Thursday’s task was scrub clearance to increase habitat connectivity for reptiles and today we were clearing the shore of Ibsley Water to improve habitat for nesting lapwing next spring.

About ten days ago the apprentices put out a trailcam and today we got it in to look at the images. There were not a great many but the range of species captured was impressive. There was one shot of a passing fox, several of fallow deer and grey squirrel. Bird were fewer with one shot each of blackbird and blue tit, but several of tawny owl and on more than one night too. The picture quality was not great but the owl was landing in front of the camera, possibly to take small invertebrate prey.

Throughout the week I have been checking the roosting great white egret on Ivy Lake when I go to lock up the hides, I suspect there are as many as five around but still have yet to see more than four together, this evening there were three.

The rain today caused the Dockens Water to flood into Ivy Lake and it is now filling at last, hopefully the reedbed in front of Ivy North hide will have enough water for the bittern to favour this area soon, one was seen from there on Wednesday.

A feature of this winter is the unusual number of pochard on the lakes, or at least unusual for recent years. This morning there were 109 on Ivy Lake and at dusk at least 150. It appears that they gather on Ivy Lake in the late afternoon before flying off at dusk in groups of ten to twenty, probably to feed. At the same time the tufted duck, which used to roost on Ivy Lake also leave, I am not sure where they go but I did notice a lot fly in just as it got dark when I was counting the goosander from Goosander hide on Tuesday, I suspect they go to roost there rather than to feed. Walking back from Ivy South hide after locking up usually happens more or less in the dark at this time of year and a feature has been the squeaking calls of mandarin duck gathered on the silt pond, in the gloom I have just been able to make out as many as ten drakes displaying on some evenings.

The black-necked grebe has been seen daily on Ibsley Water as has at least one water pipit and green sandpiper. The grebe has been favouring the western shore to the north of the low islands, the water pipit and sandpiper the shore near Tern and Goosander hides. However for many visitors it has not been the rarer bird that have attracted to interest but the starling roost. The numbers are not exceptionally large but they can put on quiet a good show looking west into the last light of the setting sun. this evening they were especially spectacular, climbing high into the air in an effort to avoid a hunting peregrine.

The peregrine was keeping the main flock high in the air but the draw of the roost was strong and they were falling down in a column whenever they could risk it.

Starlings 5

One group broke away in an exceptionally tight ball of birds and just dropped like a stone from the spiralling flock.

The starlings had all gone to roost by about 16:15, so if you want to give them a try I would try to arrive by 16:00 at the latest, viewing is good from the high point at the back of the main car park and possible, but sometimes less easy, from the Tern hide.

A Misty Morning

A fine and frosty morning, perhaps the first that has felt properly wintry. Having scraped the frost from my windscreen I headed to Blashford across a New Forest washed with mist. I stopped briefly near our reserve at Linwood and took the picture below.

In the Avon Valley the mist was thicker and there was almost nothing within viewing range at the hides, but it still made for an atmospheric scene.

The mist soon cleared and the day was a fine one for working with the volunteers out on the reserve. Our team is somewhat larger than usual at present as we have two Apprentice Rangers from the New Forest National Park working on the reserve until early January. Today we were felling grey alder trees on the path towards Lapwing hide. These trees are similar to our native alder but tend to grow rather larger and faster and have a habit of spreading far and wide by seed. We are removing them to allow the native alder to grow unhindered and diversify the habitat along the path edges where more light will now get down to the ground layer.

I took advantage of the fine evening to make a count of the goosander roost, I managed to see at least 118 gathered in two groups near the Goosander hide, there were at least 35 adult drakes, very close to the average of one third that I have recorded over many years. The rest were what are known as “redheads” that is birds with grey bodies and reddish-brown heads, these will include both adult females and immature birds of both sexes. Other bird in the bay were a single green sandpiper very close to the hide and at least 14 goldeneye.

Yesterday evening as I closed Ivy North hide I could clearly see 4 great white egret roosting in the dead alder trees. I have suspected there were more than the three that are often seen for sometime now but have been unable to prove it before. Generally yesterday was a better day for bird sightings despite the poorer weather, but then using a chainsaw all day is not particularly conducive to seeing birds! Other sightings yesterday included the black-necked grebe on Ibsey Water, along with at least 78 pochard, a good count these days and all the better as there were at least 73 on Ivy Lake as well. Ten or twenty years ago these figures would have been unremarkable, but these ducks are in decline all over Europe for a variety of reasons including lowered breed success due to a significant imbalance of the sexes.

Out on the reserve yesterday I flushed a woodcock between Goosander and Lapwing hides, my first of the winter, whilst in the same area 2 raven flew over and a chiffchaff was calling in the willows. At dusk I took a quick look at the gull roost, I could not find the ring-billed gull, but there were at least 11 yellow-legged gull, all adult and including the atypical adult bird with the heavily marked head. Yellow-legged gull adults usually have all white heads in winter, in contrast to most of the other large gulls, this well marked bird is similar to those of the race that is found on the Azores,  separated as the race “atlantis”. Gull watching came to an end when an adult female peregrine made several low passes over the roost, scattering it in all directions.

With more wintry weather it is perhaps unsurprising that the moth trap is getting quieter, despite this, but appropriate to the season recent catches have included Winter moth, December moth and mottled umber.

Damp Days

The long, hot summer seems an age away now, with most days dominated by drizzle (Friday excepted). It is still very mild, but the combination of damp and mildness makes for difficult working conditions. Winter work on the reserve is mostly fairly heavy, with lots of protective clothing and machinery, things that do not go well with mild damp weather. Despite this we have been busy with the volunteers clearing sites and generally preparing for the planned updates to the reserve. Alongside this there is still the usual maintenance to be done and today I was out with the team repairing the boardwalk and trimming back the path sides.

The Pop-up Cafe was in the Centre again today, sadly things were rather quiet, probably a result of the poor weather, the cakes were as good as ever, if you missed them, they will be back on the 16th of December and New Year’s Day with more.

Out on the reserve things seem fairly quiet, I say this but there was quiet a lot to see. On Ibsley Water there was a black-necked grebe, 2 dunlin, green sandpiper, a variety of duck including pintail, wigeon, pochard, goosander, goldeneye and at dusk the gull roost and starling murmuration. I just missed seeing a peregrine take a drake pochard, I would have thought rather a bulky prey item for this falcon. Other birds today included red kite, chiffchaff, Cetti’s warbler and at dusk on Ivy Lake three roosting great white egret, all in all not bad for a “quiet day”!

 

The Turn of the Season

As autumn slips into winter and the last of the leaves get blown from the trees we are seeing the wildlife of the reserve taking on a more wintry feel too. At the weekend the goosander roost passed 100 birds for the first time, whilst the gull roost is now well up into the thousands. A black-necked grebe has returned to Ibsley Water, although as is typical, it is frequenting the extreme northern shore of the lake. The startling roost in reeds just west of the A338 Salisbury Road, but best viewed from the main car park area or Lapwing hide, had built up and is now quite a sight in a fine evening.

At times this gathering is attracting various predators, over the last ten days or so I have seen peregrine, sparrowhawk, marsh harrier and goshawk all eyeing up the roost for a potential snack.

Green sandpiper and water pipit are still being regularly seen at various points around Ibsley Water, but Goosander hide seems to be the most frequent place for good views of both. At least 3 great white egret are wandering the reserve and out into the valley, I have not managed to see more than three at any one time, but I strongly suspect there are more, perhaps up to five?

Visitors to the reserve may find diversions or short path closures over the next few weeks as we are doing some tree thinning, it should be possible to access all the hides though. The trees we are removing are mainly planted aliens species such as grey and Italian alder or species such as sycamore and Scots pine that are crowding more desirable species oak, elm and ash. The objective is to thin areas that were planted too densely and promote native species over non-natives, this should benefit a range of wildlife in the long run. Where possible we will be leaving standing dead trees, or lying dead wood for beetles and other invertebrates.

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!

Round-up

A busy today started with a water pipit and a fine female marsh harrier from Tern hide as I opened up, it was also pleasing to see a small flock of linnet still present on the shore just east of the hide.

It was then into the main job of the morning, getting the ponies off site and into the trailers. Unfortunately they had other ideas, or at least two of them did, so this task too almost two hours. Luckily we had the quad bike available as with repeated doubling back I must have travelled the full length of the lake at least four or five times. Eventually we got them all into the corral, at which point it started to rain and I realised that my coat, which had been on the back of the bike had gone, no doubt bounced off at some point when I was negotiating some more bouncy part of the lake shore. The lack of my coat was unfortunate, but the lack of the keys in the pocket was potentially disastrous.  So it was back up the lake shore, finally I found it lying in a deep puddle at the north end, so I would have got wetter putting it on, but at least the keys were found.

Then back to the Centre to finish setting up for the gulls identification course that we were running with Hampshire Ornithological Society, due to start at 12:30 and needing the keys to get into the classroom. So just in time all was running like somewhat over-wound clockwork, fortunately I had Marcus Ward and Ollie Frampton to help out and fill in for my deficiencies.

Usually the gulls roost more or less int he middle of Ibsley Water, but this autumn they have been tending to stay closer to the northern shore, making them harder to see. Last Thursday the roost appeared to have settled into the more typical pattern, so I was hopeful of being able to get some good views for the course attendees. Unfortunately , from Tern hide where my groups was the gulls were very distant, making gull spotting trickier than I had hoped. Luckily, although they were fewer gulls we did see some other birds, most notably a good starling roost, which were kept in the air  by a hunting sparrowhawk. A group of three drake goldeneye close to the hide were also good to see and they spent a little time displaying, as they often do towards dusk.

Advance Notice

On Sunday we are running a training course on the identification of gulls at Blashford, this will mean that the Tern, Goosander and Lapwing hides will be in use by groups on the course from mid afternoon, so if you are visiting on Sunday and not on the course you might want to visit these hides in the morning or early afternoon instead.

I am sometimes asked for an advised route around the reserve and although the “best” route is always a matter of circumstances on the day there are some general rules that hold true. So Ivy North hide faces south-east, this makes it difficult on a sunny morning, Ivy South faces east and likewise difficult early on in sunshine, so both of these are probably best in the afternoon. The Woodland hide is less of an issue, although the light is best here in the afternoon also. The Tern hide faces north so is pretty good all day. Goosander hide faces north west, so is at its best in the morning and the same is true of Lapwing hide, which faces almost due west, so is very hard work on a sunny afternoon.

The above obviously is only a choice dictated by the direction of the light, there are other factors too of course. Wind direction can be important, most birds will seek shelter and this needs to be considered. In a strong northerly, Tern hide will be both a long way from the birds sheltering under the northern shore of Ibsley Water, nearly a kilometre away and if you open the window you will be looking into the teeth of the wind! By contrast the northern end of Ivy Lake near Ivy North hide will be sheltered and with luck full of birds.

Then there is what you want to see, not a problem if you just want to see a range of birds, being guided by the weather and lighting will probably be the best option. There are some obvious rules, the birds that gather to roost will only be doing so at the end of the day and you will need to be in the right place to see them. The gulls roost on Ibsley Water is well known and is the attraction for the identification course. Ibsley also hosts a roost gathering of goosander, which mainly roost in the bay at Goosander hide, although they are usually only there in the minutes just before darkness. They fly in from all directions but can often be best seen doing so from the bank at the back of the main car park, which is also the best place to view the starling murmuration and get an overview of the gull roost. If it is great white egret you want to see then Ivy North at the end of the day is the place, recently there have been three there each evening, there is also a cormorant roost in the trees here.

By contrast if you are looking for finches, don’t leave it too late, they tend to get up late and go to bed early, the Woodland hide feeders will be busy with tits from dawn ’til dusk but the finches tend to turn up in the middle part of the morning and are often heading off to roost not long after 3:00 pm in the winter.

Some species are more obvious at certain times of the day, birds of prey will soar around mainly during the middle part of the day when the ground has warmed to aid this kind of flight by causing upward air currents. Water rail and Cetti’s warbler are usually far more vocal around dusk. Pochard tend to feed at night and roost during the day, whereas tufted duck are typically the reverse, feeding in the day and roosting at night.

So if planning a birding trip consider the conditions on the day and what you are most keen to see and you should get the most out of your visit. The above is just about Blashford Lakes, but every destination will have a range of factors that will be at play. Wherever you go it always pays to be lucky of course, but to some degree you can make your own luck by making good decisions about how you go about your visit.

 

Time for a Trim

Tuesday is one of our volunteer task days at Blashford and today’s task was to cut the vegetation in front of Ivy North hide and open up some sight lines through the reedbed. The hides are great for seeing birds but only if we can keep the views open, but more than this we are also trying to ensure that people get the best possible views of the wildlife that might be on offer. One of the occasional treats at Ivy North is the chance to see a bittern and this is one of the main objectives of the reed cutting near this hide.

Reeds at Ivy North hide before cutting sight lines.

The reeds have been spreading and this year’s growth was especially vigorous, meaning than cutting the line was hard work. The one positive was that it was fairly dry, although this made cutting easier to do it means that there is not likely to be a bittern there any time soon.

This year I also cut a line through to the water right in front of the hide.

The objective of a hide should be to give the observer a view that they would not get otherwise. At Blashford we have tried, as much as possible, to get each hide to deliver something different and hopefully at least one or two will have something really worth seeing from them at all times of the year. Today there were two peregrine near Tern hide, with one adult perched on one of the posts near the hide, the water pipit was seen from both Tern and Goosander hide and a great white egret from Ivy North, despite our  working outside the hide. The only other birds there whilst we were working were two or more water rail heard calling and a singing Cetti’s warbler.

We are soon looking to replace the Tern hide, it is in a very exposed location and is showing signs of age ahead of most of the others. Replacement offers the chance to tweak things a bit too and the new hide is to be slightly larges, slightly higher off the ground and moved ever so slightly, all changes that should give improved views. Expect to read more about this and other updates top the reserve in the coming weeks.

Letting the Light in

For several weeks now there have been contractors working up at the Linwood reserve working to open up an areas of mire habitat that had become seriously shaded. This happens more or less imperceptibly, in this case it was easy to think the area had always been continuous woodland , but the flora told a different story. Many species present, although declining, were ones that do not tolerate being heavily shaded. In addition when the trees are looked at more closely it was obvious that many were no more than twenty or thirty years old. The Our Present, Our Future (OPOF) New Forest National Park project had a strand that was dedicated to helping to restore habitats such as this and it is this project that has enabled the heavy work to be done.

Work to clear shading trees from Linwood mire habitats

The oak and beech trees have been left alone, the opening up has been achieved by felling birch and pollarding willow. Some trees have been ring-barked to leave them as valuable standing deadwood habitat. It will be interesting to see how species such as white sedge and bog myrtle respond to having access to more light in the years to come.

Last night was very mild and I was looking forward to seeing what the moth trap had caught. The trap was against the wall of the Centre and there were 45 “November” moth on the wall alone! November moths are hard to identify reliably as there are a few very similar species, so I lump them together when recording. Other moths included three merveille du jour.

Merveille du Jour

Merveille du Jour – I know I have used pictures of them many times, but they are one of my favourite moths!

There were also late large yellow underwing and shuttle-shaped dart as well as more seasonable black rustic, yellow-line Quaker, red-line Quaker, chestnut and dark chestnut.

dark chestnut 2

Dark chestnut, it is usually darker than the chestnut and has more pointed wing-tips.

In all there were 16 species and over 70 individual moths, other notable ones were a dark sword-grass and two grey shoulder-knot.

We have been doing a fair bit of work around the hides recently, mostly aimed at improving the views from them. Tomorrow it is the turn of Ivy North hide, so I expect there will not be much to be seen in the northern part of Ivy Lake during the day. With luck I will get some sight-lines cut through the reeds, so perhaps the bittern will get easier to see, if it is still around.

Wilder Britain

The past week has seen a lot of coverage of the environment and our impacts upon it. There has been the WWF report on extinction of vertebrates Living Planet Report 2108 which mirrors the decline in invertebrates noted in the tropics and Germany I linked in my recent post. Today the Meteorological Office report indicating climate change Met Office Climate Report has received much media coverage.

All of these reports are pointing in one direction, we need to get on with doing something about the state of our environment, our efforts so far have just not been enough to make any real difference. Some issues will only be properly tackled by action at national or international level, we can lobby to get policies changed, but we need to be acting more immediately if things are going to be improved or even if declines are to be halted.

So what is to be done? Can anything be done? The Wildlife Trusts have proposed that we should be seeking a “Wilder Britain”, Wilder Britain press release  essentially one in which we halt and then reverse the declines by establishing a nature recovery network. The objective is stated as follows: “The Wildlife Trusts believe in a future Britain where nature is a normal part of childhood and where wildlife thrives across the landscape. Where our urban spaces are green jungles and our seas are bursting with life. Where seeing a hedgehog is an every day experience.” The full document expands upon just how this might be achieved, Nature Recovery Network. 

A Wilder Britain, it is surely what we need,  it is now acknowledged that access to nature is really good for our mental health, we need access to nature. In addition an environment that is good for wildlife will be one that has low levels of pollutants, is varied, interesting and exciting. This is not a people or wildlife dichotomy, this is nature because we need it.

My worry is perhaps that we have been saying these kind of things for many years now without much effect. For example the value of larger, more connected areas for nature are now well recognised. However the research that demonstrated the truth of this was published in 1967 Theory of island bio-geography , it has taken over fifty years to break through to become mainstream thinking! If nature is to stand any chance of recovering, we probably don’t have fifty years to wait for the idea to take hold. If you are interested in a more accessible approach to the theory the excellent Song of the Dodo by David Quammen is a must read, brilliantly written and the kind of book that cannot but make you stop and think about where we are going.

In amongst the reserve reports you can expect to see more about these issues in future blogs, you have been warned!
