Recently on the Reserve

There is a good range of species around the lakes at present, although numbers are not very high. Ibsley Water does not have a lot of wildfowl this winter due to rather weak water-weed growth, but what it lacks in numbers it makes up for in variety. The long-tailed duck has been showing well at times near Goosander and Tern hides and there is now a black-necked grebe frequenting the northern shore of the lake. Recent rain has resulted in some local flooding in the Avon Valley, conditions which lead to increases in numbers of pintail and black-tailed godwit, both of which will visit Ibsley Water during the day. Recently there have been 70 or more pintail and up to 400 godwit at times on the lake. In addition we have a wintering common sandpiper and at least 1 water pipit, both sometimes right in front of Tern Hide.

By contrast Ivy Lake has been very busy with large numbers of wildfowl with hundreds of gadwall, wigeon and coot. There have also been up to 4 great white egret, including “Walter”. Cetti’s warbler seem to be at an all time high on the reserve with one even using the woodland near the Centre and frequently in the vegetation beside the dipping pond. There have been a number of firecrest around, with the hollies along the Dockens Water a favourite location, this very fine picture was sent in last week.

Doug also sent in a nice shot of a female shoveler, a duck that is present in only moderate numbers this winter so far.

Each winter for the last few years we have had two apprentices from the New Forest National Park working on the reserve for a couple of months, they provide valuable assistance to me on days when I have no volunteer working parties. The apprentices have been doing great work recently, laying two sections of hedge along the western side of Ellingham Lake and on Friday we took to the water and cleared three of the islands on the western side of Ibsley Water of their annual vegetation.

On Saturday I ran a gull identification workshop in partnership with Hampshire Ornithological Society. These things are rather hit and miss when it comes to going out to see the gulls, so much depends upon the weather and even then the gulls may decide to roost distantly from the hides. We did not find any unusual gulls, but the long-tailed duck, black-necked grebe, goosander roost and a very fine peregrine were all highlights. I was with a group at Tern Hide and we had the peregrine perch on a post close to the hide.

Other recent sightings have included a regular female marsh harrier, a modest starling roost to the north of Ibsley Water, a young female scaup on Rockford Lake and an otter near Ivy South hide, although an American mink was seen there at the weekend. The Ibsley Water gull roost has contained 6 or more yellow-legged gull, an adult Caspian gull and up to 2 Mediterranean gull.

At Last, a Bit of Fine Weather

As December starts the winter has turned a little more like winter, with frost at night and finally a drier spell. This has allowed us to get a few outstanding tasks done, yesterday’s was clearing the vegetation in front of the Ivy North Hide and opening up the channels through the reedbed.

As we worked at least 2 Cetti’s warbler were moving about in the reeds and water rail were squealing frequently, although went typically unseen.

Other recent tasks have included laying some hedge lengths, clearing bramble from grassland areas and also making a start on removing some infected ash trees. The last will be a large task in the next couple of years. You may have heard about ash die-back, it is a fungal infection that kills ash trees and is expected to result in over 95% of our ash being lost. The disease originated in the Far East and probably arrived in Europe via the horticultural trade.

Where these trees are deep in the woods this will mean more standing deadwood habitat, so not an entirely bad thing. Where we have paths , hides, roads and car parks they will have to be felled before they fall. There is no doubt this is going to have a noticeable impact as ash is a frequent tree and it will impact upon species that depend upon this tree. It is also going to be a very expensive task for land managers, at Blashford we only have a couple of hundred, but still a lot of work. The one positive note is that work at Kew Gardens has revealed that some British ash trees show some immunity, so if these survive they will be available to provide a seed source to enable restocking. It will still be a long time before we get back to ash being once again a frequent tree in our landscape.

Out on the reserve things have also taken a more wintery turn, wildfowl numbers have picked up, although only on Ivy Lake is this very noticeable. The goosander roost on Ibsley Water is growing and has over 80 birds now. Also on Ibsley Water a long-tailed duck has been present for a while now and on Monday 3 black-necked grebe were present, but were perhaps only passing through as I don’t think they were seen yesterday. Less seasonal is the common sandpiper, these usually just pass through in autumn and only green sandpiper normally winter with us. The rain has resulted in a significant rise in water levels, the water pipits have become much less obvious following the rise, perhaps because the rise has covered a lot of the exposed weed along the shore.

We are hoping the dry weather will hang on for a day or two more so we can fill the pot-holes in the entrance track, with luck we will be doing this on Thursday, so access to the Centre car park will be somewhat restricted.

Summer Passing

It seems that once the 30 Days Wild are over, the signs of passing summer become increasingly obvious. I heard my last singing cuckoo on 22nd June, we now know that many will have left the country southward by the end of June, thanks to the advent of tiny satellite trackers fitted to some birds by the British Trust for Ornithology (BTO), you can follow their progress via a link on their website.

At Blashford Lakes common sandpiper are returning and on Sunday there was a greenshank, returned from breeding, probably in Scandinavia. Lots of the swift have left already as have the first generation of young sand martin. Over at Fishlake Meadows an osprey is being seen regularly, with other sightings including up to six cattle egret.

Around the reserves we are now at the peak of butterfly numbers, with lots of “Browns” especially.

This week will probably see “Peak-gatekeeper” and we may have just passed peak-meadow brown. Speckled wood, by contrast are perhaps the only butterfly with a real chance of being seen throughout the 26 weeks of the butterfly recording season as it has continuously overlapping broods.

In places you may notice a few very dark, almost black, meadow brown, actually these may well be ringlet, with slightly rounder wings and multiple eye-spots.

Several species now have their summer broods emerging, this is true for common blue, brown argus, small copper and peacock.

The warm weather has been great for insects in general, there have been good numbers of dragonflies, including a single lesser emperor, a formerly very rare migrant species that seems to be getting ever more frequent.

 

30 Days Wild – Day 24

A warm clam night, ideal for moths and so it proved, with the best catches of the year so  far. There was not a lot of great note, just all the usual suspects plus a lot of small species, which tend to be caught much more on calm nights. In fact it was the micro moths that provided the best moth of the night, assuming I have managed to identify it accurately, it was a Tortrix moth, Pammene trauniana.

The grass snakes were putting on a show again yesterday at Ivy South Hide, with four individuals on the tree stump in front of the hide.

Signs of the year moving on are starting to appear, a common sandpiper on Ibsley Water will be one on the return journey south and the moulting goose flocks are building in size.

There was clearly an arrival of painted lady butterflies with several around in the afternoon, perhaps more to follow and maybe other species too.

Following yesterday’s clearwing success, I tried the lures again at lunchtime and again attracted a single orange-tailed clearwing. This time I did manage some rather better pictures.

A Constellation of Garlic

A fairly busy day on the reserve today with a steady stream of new visitors, it is always good to encounter people who are still just discovering us after all this time! I was out with the volunteers removing brambles from a warm south-facing bank which I hope will prove popular with insects and reptiles.

It seems odd to say there was not a lot of bird news when the Bonaparte’s gull was still present, but it has been here a while now and most who were keen to see it have done so by now. The first summer little gull is also still with us, otherwise migrants were a dunlin, a whimbrel and at least three common sandpiper. Numbers of swift have increased again I think, with at least 100 zooming noisily about this afternoon.

Out on the edge of the lichen heath I saw a small copper and a grey-patched mining bee.

I only saw my first damselfly of the year a couple of days ago, I don’t think I have ever waited until May before I saw my first of the year before. My first was, as expected, a large red damselfly and today I saw a single female common blue damselfly.

As you can see it is not at all blue, but it has not long hatched out and has yet to acquire its colour, many females do not get all that blue anyway.

The wild daffodil have long since ceased flowering and the bluebell are starting to go over, but the reserve’s only patch of ramsons, also known as wild garlic, is looking very fine and in full, starry flower. Half close your eyes and it looks like a firework display  worthy of any New Year. I was hoping to find the hoverfly that feeds on it as it would be new for the reserve, but no such luck.

Although I had not luck with the hoverfly I did find a snail-killing fly near the Centre Pond, I think it is Tetanocera ferruginea.

Although it was a rather cool night the moth trap did catch a few species including my first pale pinion of this year, never an abundant species, I usually see only a few each year.

Rafts, Birds and Bees

It’s that time of year again, the tern rafts are going out and the migrant waders are on the move. On Tuesday the volunteers got two rafts out onto Ivy Lake, after wintering on the shore.

Adding nesting substrate to the raft.

They were occupied by common tern within minutes, although black-headed gull also arrived in numbers and by the end of the day were the only species present. This highlights one of the big problems that terns have these days, as their nesting habitats reduce they are competing more and more with gulls and usually lose out to them.

Yesterday’s migrant birds were mainly waders heading to the high Arctic and included a common sandpiper, a bar-tailed godwit,

The waders that nest with us are all displaying but none seem to have really settled down yet. Little ringed plover are especially in evidence near Tern Hide.

Although it has got cooler the spring insects are still in evidence and some of the earlier season species are beginning to disappear for another year. One such is the rare grey-backed mining bee Andrena vaga, there are only a few females to be found now, but as they feed on willow pollen their food will soon run out.

If you look at a solitary bee nesting bank there are usually lots of, what at first, look like wasps, but these are actually parasitic bees. Many are very specific as to their host species, I came across two species yesterday. I found what I think was Lathbury’s nomad bee, which uses grey-backed and  the commoner ashy mining bee as hosts.

I also found lots of painted nomad bee, which visits the nests of the common yellow-legged mining bee.

Work continues on the parking area close to the Education Centre, which means that it will not be available for parking until after the weekend, please take note of any signs to keep safe on your visit whilst we have machinery working on site.

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.

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

 

Reports and a Bit of Garden Wildlife

5th October reports from Blashford showed that all the main player are still present. On Ibsley Water the ferruginous duck was still around the north end of the Long Spit visible from either or both of Tern  and Goosander hides. The wood sandpiper seems to have relocated to the shore near Lapwing hide, with both common and green sandpipers also still present to “complete the set”. A few wigeon and a single pintail are mingling with the wildfowl and it is worth checking for the occasionally reported juvenile garganey. Both great white egret and several little egret were also about.

Over on Ivy Lake the bittern was seen on the edge of the reeds near Ivy North hide, viewed from the screen along the path between Ivy Lake and Rockford Lake.

I was not at Blashford myself so my wildlife sightings were restricted to my garden and especially the moth trap, a mild, calm, damp night resulted in a good catch of autumnal species.

The angle shades is perhaps the moth most adapted to hiding in piles of dead leaves and a species that can be seen as an adult all through the year.

The dark sword-grass is a migrant and although they can turn up at almost anytime, they are mush more frequent in autumn.

deep-brown dart

Whilst some autumn moths are yellow to hide in autumn leaves, others just go down the very dull and unobtrusive route, the deep-brown dart is one such species.

feathered ranunculus

feathered ranunculus

Feathered ranunculus is an autumn species that lives mainly around the coasts on cliffs. It colonised the mainland coast of Hampshire in the late 1970s. I remember this well as I was working at Titchfield Haven at the time and caught a number of them, indicating that there were established on the mainland and not just wandering from the Isle of Wight.

southern chestnut

southern chestnut

The southern chestnut was first discovered in Britain in 1990 in Sussex. At the time it was considered that it had previously been overlooked, this may be so, but what is certain is that it has increased greatly since and is now quiet frequent across the New Forest heaths and in similar habitat elsewhere in southern England.

Other species in the trap included large yellow underwing, lesser yellow underwing, lunar underwing, willow beauty, shuttle-shaped dart, black rustic, turnip, sallow, pine carpet, spruce carpet, cypress carpet, square-spot rustic and broad-bordered yellow underwing.

I have recently found a new species in my garden, a most unusual plant, called yellow dodder. The dodders are parasitic plants that have roots only as small seedlings and once their tendrils have found a host the tap into the plant to gain all their nutrients and do away with their own roots. There are native species of dodder that can be seen on gorse and heather plants, especially in the New Forest, yellow dodder is not a native and comes from the Americas, almost certainly with bird seed and most likely in nyger seed and this plant was climbing up a self-seeded nyger plant, supporting this idea.

Paths to Wildlife

A busy few days, either working with the volunteers or on a chainsaw course has meant that I have not really had time to look around the reserve or hear many reports from those that have. As it happens it seems there has been little change, the ferruginous duck is still present and frequenting the group of sticks at the end of Long Spit in Ibsley Water and when not there on the long Spit itself, although often only visible from Goosander hide. The wood sandpiper is also still around, although now often on the eastern shore of the lake between Goosander and Lapwing hides. There are still 2 green sandpiper a common sandpiper and a dozen or so wigeon and both great white egret remain. The only new bird that I was aware of today was a single black-tailed godwit on the western shore of Ibsley Water.

With the volunteers were have been cutting the shore west of Goosander hide and the site of the former concrete block works to keep the habitat suitable for nesting lapwing next spring. We have also been working on the paths between Goosander and Lapwing hides. In all we have something like 8 kilometres of paths on the reserve and keeping them in a reasonable state takes quiet a bit of time and effort. We also like to try to keep them interesting, not just routes from A to B, but ones on which you might come across things of interest. Today we were clearing the paths, but also opening up the edges to provide sheltered clearings and making a sand bank for solitary bees to nest.

I am keen to try and get the management of the reserve to always be maximising the opportunities for all kinds of wildlife, both because this makes it a more interesting place  to visit and because our beleaguered wildlife needs all the opportunities it can get.

 

 

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.
