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.

Looking out from Ivy North Hide before we started.

The main channel cleared

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.

Bee is for Blashford

Or maybe Blashford is for bees, well of course it is! Blashford is for all wildlife and the people who like to experience it. Everyone knows the honey bee and bumble bees, although perhaps not that there are 28 species of them. However there are something like 250 other species of bees in Britain and they all spend their days visiting flowers and pollinating them. These 250 are the so called solitary bees, despite the name they can occur in great aggregations, importantly though each nest is the domain of just one female, there are no worker bees.

There has been much coverage recently about the declines in insect numbers around the world and that of pollinating insects in particular, perhaps because they are economically important to us as pollinators of crops. Declines could be for many reasons and probably are multi-factored, but a general loss of habitat and an increasing uniformity in what is left, along with increased prevalence of chemical contaminants are all likely contributors. Some enlightened local authorities are modifying their grass mowing regimes on verges, roundabouts and recreation site to allow more flowering, some of the best are actually seeding back wildflowers or using “meadow mixes”. In fact we can all help by providing flowers that are good sources of nectar and by valuing some of the “weeds” that we might have removed in the past. For instance a lawn with dandelions may not win the green-keepers prize but these are a very important source of food for early flying bees and hoverflies.

Blashford Lakes has lots of nectar sources, especially at this time of year when willows are important for many species and so has lots of solitary bees. Many also need bare, sandy soil to dig their nests and we have that in abundance too.

One of the problems with solitary bees is that some species are very similar to one another and so difficult to identify in the field. Although the grey-backed mining bee female is distinctive the male looks very like the male of another species, the ashy mining bee.

One of the commonest mining bees around at present is the yellow-legged mining bee, which can be found nesting in bare ground in banks, lawns and various other places.

yellow-legged mining bee (male) – or at least I think it is!

Some bees are neither colonial nor make their own solitary nests, they are nest parasites of other bees. One genus of bees the Nomada bees specialise in this way of life, often specialising on one particular host species. The yellow-legged mining bee plays unwilling host to the painted nomad bee, which looks very wasp-like.

The last few of days have seen big arrivals of hirundines, Monday was almost all sand martin, yesterday there were a few swallow and the odd house martin and today there were even more swallow, probably over 50. On Ibsley Water there a couple of pairs of oystercatcher, a pair of redshank, probably five little ringed plover, several lapwing and today two green sandpiper. Meanwhile around the Centre and Woodland Hide the wheezing of brambling is very much in evidence, particularly in the morning, there are at least 30 and I suspect 50 or more around just now.

And remember it does not take much effort not to mow the lawn for a few days and let the dandelions flower to feed the bees. You could put your feet up and have a cup of tea, or a beer (other drinks are available), whilst making your own contribution to Wilding Hampshire!

From all Corners

There were birds from all over the place on the reserve today. All the way from Siberia; the yellow-browed warbler was again near Ivy South hide as I opened up, giving good views until it disappeared before our very eyes. It makes astonishingly fast changes of direction which mean that following its movements for very long is incredibly difficult.

From North America we had; lesser scaup, a drake near the furthest shore of Ibsley Water, probably last winter’s bird returned by popular demand. These duck are similar in appearance to the greater scaup which is much more familiar in Europe, but smaller, around the size of a tufted duck.

From all over northern and eastern Europe we had all the other wildfowl and a good few other birds too. Arrived from the Alps and now to be seen on the shores of Ibsley Water are the water pipit, I got a mediocre picture of one today.

And finally from just up the road somewhere we have the rest, including this adult female peregrine, seen here in another iffy picture!

Other birds to be seen out and about on the reserve today were the bittern at Ivy North hide along with Walter the great white egret. Other birds to be seen on Ibsley Water included green sandpiper, pintail and in the gull roost several yellow-legged gull and three Mediterranean gull. 

However the reserve is not just about birds, today there was also cake and lots of it, with another successful day for the pop-up cafe.  I also took some non-birdy pictures, largely due to a failure to get very good ones of the birds. There are quite a few fungi about now, scarlet elf-cup are just starting to appear in numbers as are lost of Turkeytail.

Moss, fern and Turkeytail

The bare trees make it possible to appreciate how much lichen some of them have on their branches, the willow near Lapwing hide are especially heavily festooned.

Other species grow on the trunks of trees.

Lichens are a mash-up of alga and fungus, although it now appears it is probably rather more complicated than this.

The reserve was busy today despite reduced parking due to the ongoing levelling works near the Centre, but hopefully this work will be completed by the end of the coming week and things will be slightly closer to normal again, at least for a time.

Another Year

What a great start to the New Year, a beautiful morning and the reserve was busy with visitors and birds for them to see. So busy in fact that the Pop-up cafe ran out of cake! This may also be because word is getting around that the cakes are exceedingly fine so people get in early, they will be back next Sunday though, so all is not lost.

A New Year means a new “list” not that I ever manage to keep one going to year’s end, but a good start for me at least, with 78 species recorded, 75 of them at Blashford.

Ibsley Water featured at least two (although I think there must be more) water pipit, seen from all three hides during the day, the black-necked grebe, typically near the north-western shore, a fly-over by the dark-bellied brent goose (rare at Blashford), a marsh harrier, green sandpiper and all the usual wildfowl. In the afternoon the Caspian gull was in the roost along with about 10 yellow-legged gull.

Meanwhile Ivy Lake had the bittern on view on and off for much of the day at Ivy North hide along with a supporting caste of Cetti’s warbler, chiffchaff and water rail, joined later by first one and then two great white egret which stayed to roost with the cormorants.

At Woodland hide the regular woodland birds have now been joined by a few reed bunting, but there is no sign as yet of any redpoll or brambling, but it is early days. More widely around the reserve a firecrest was at the road crossing to Goosander hide and several more chiffchaff were in the reeds and willows on the walk to Lapwing hide, where there was a reed bunting giving brief snatches of song, they usually don=t start until well into the spring.

Despite recording 75 species on the reserve, I never saw a greenfinch! and there were a few other species missing that are generally not that difficult to see.

I saw just four mammal species (not counting humans) all day and two of those were non-natives, grey squirrel, fallow deer, roe deer and a wood mouse, live-trapped in the loft. Meanwhile the year’s moth list got off to a roaring start with a single mottled umber, although by convention moths are recorded as being on the previous day as most fly just after dusk, so this is when they are attracted to the light.

29th Dec – Sightings

No pictures today as my camera has died on me. Opening the hides first thing there was a water pipit at Tern hide (later I also had singles at both Goosander and Lapwing hides as well), also from there a new high count of linnet 108, and a chiffchaff beside the hide. At Ivy North hide the bittern was standing high in the reedmace giving great views. At the Woodland hide the reed bunting count had risen to 7 along with all the usual woodland birds.

Walking round the reserve the number of species singing was notable, I heard mistle thrush, song thrush, great tit, treecreeper, robin and Cetti’s warbler between the Centre and Ivy South hide.

In the afternoon a first winter Caspian gull was showing well swimming among the larger gulls from at least 2 o’clock. Despite searches by a few people no other notable gulls were found apart from rather more yellow-legged gull than recently seen, with perhaps 10 or more.

Towards dusk a green sandpiper was at Goosander hide, a great white egret flew over heading south, I assumed the egret was heading to roost in the trees at Ivy Lake, but when I got there none were to be seen. A small starling roost gathered over the north end of Ibsley Water, maybe 1000 or so birds, being chased by a peregrine. The peregrine them forced low over the water, so low that many wings broke the surface and produced a sudden flash of spray.

 

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 gathering twisting to avoid a peregrine, there is a small group coming int to join them towards the top left.

Some of the flock trying to funnel down into the roost site

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.

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.

The valley of the Dockens Water on a frosty morning

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 misty view from Ivy South hide

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.

Felling grey alder beside the path to Lapwing hide

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.

Starling murmuration by Jon Mitchell

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!
