Seasonal Shift

Although the hides remain closed good views can be had of Ibsley Water from the viewpoint at the back of the main car park. Although views of most things on this large lake are distant at least from there you can see most of the lake. I have found one or two people wandering off the paths recently to try to get to the lakeshore, this is unacceptable which is highlighted by the fact that it has been the birds taking flight that has brought it to my attention. I also found someone standing on a badger sett the other day, also unacceptable. In each case the people concerned have failed to see much and caused any birds nearby to fly off.

From the viewpoint this morning I saw a merlin, a peregrine, over 50 wigeon, a few pintail (yesterday there were 8), 18 goosander, about 40 shoveler and over a 1000 house martin, not bad for a quick scan. The martins have been held up by the inclement weather and have been feeding over the lake for a few days, there have also been a few swallow and one or two sand martin. Later when I was checking the hide the peregrine was perched on a post near Tern Hide and I got the shot below. With that beak and those claws it is easy to see why this is such a feared predator.

I have yet to stay until dusk to check the gull roost, but numbers are building now, a quick look before leaving yesterday yielded 3 yellow-legged gull in the hundreds of lesser black-backed gull and a single first winter common gull in the black-headed gull part of the flock.

Elsewhere on the reserve there are good numbers of chiffchaff, so far no yellow-browed warbler, but I will keep looking. Two marsh tit have been visiting the feeders, the first for a few years. It looks like being a good winter for finches, with a steady movement of siskin and recently also redpoll overhead on several days. The first redwing will be along any day now and maybe a brambling or tow passing through.

For all of the sings of approaching winter it is still quite warm by day and speckled wood remain flying in good numbers with a few whites and red admiral too. Most of the solitary bees have ended their season now but I did see this one today, I think an orange-footed furrow bee.

Likewise there are still some hoverflies on the wing, today’s brightest was this Sericomyia silentis.

I will end with a quick warning that tomorrow morning we will be working beside the path and boardwalk near Ivy South Hide, this will mean that the path may be closed for short periods.

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.

A section of hedge being prepared for laying.

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.

Trapped

The night was a little warmer and the result was the best moth catch for some time, not saying a lot perhaps, but it is only mid February. In all there were four species, a dotted border.

Two chestnut, these will have over-wintered as adult moths.

And a single micro-moth, a Tortricodes alternella, actually there was another micro, but it flew off before I could see it well enough.

Not everything in the trap was a moth though, other insects are also attracted to light, in this case a female great diving beetle.

I understand that a bittern was seen again today at Ivy North hide and a redpoll at the Woodland hide. Out on Ibsley Water single black-necked grebe, a yellow-legged gull and a water pipit were seen.

Thinning

Not a reference to the effects of advancing age but to today’s volunteer task on the reserve, which was felling some sycamore trees to open up some space. In places we have dense stands of very tall, thin sycamores which tend to over-top and then shade out other species. To reduce the negative effects of this we are thinning out a lot of the smaller trees, especially where they are growing amongst other species such as oak. It was the perfect day for felling, at least until the rain started, being cool, so I did not overheat in the protective chainsaw gear and calm, so the trees would hopefully fall where I intended them to.

By the end of the day we had cleared quite a few trees, but the more we took down the more there seemed to be! At the same time there was a more open feel to the area so we must have done something. We did come across quiet a few small, self-sown hazel and even one covered in honeysuckle and these should benefit from some more sunlight.

I left a number of the stumps fairly high, this allows me to ring-bark the stump reducing the chance of it growing back, without using pesticide and also gives the opportunity to make some cut slots and holes to allow rot to get a hold and make habitat for various invertebrates.

Chainsawing for most of the day does reduce the chance of seeing wildlife somewhat, but not completely. Locking up the hides at dusk I was lucky enough to see both great white egret and bittern at Ivy North hide. I understand the yellow-browed warbler was again near Ivy South hide and out on Ibsley Water there were peregrine, Mediterranean gull,  yellow-legged gull and black-necked grebe, but no sign of the lesser scaup, perhaps it has moved to Blashford Lake where it spent much of its time last winter when it was here. At Woodland hide there was also a brambling reported, perhaps the same bird that Tracy saw yesterday.

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.

 

It’s a Small World

Boxing Day was quite busy at Blashford, with a fair few visitors on the reserve, most who were prepared to spend the time waiting saw the bittern at Ivy North hide. Whilst they waited good views were to be had of water rail and Cetti’s warbler.

From the hides on Ibsley Water the black-necked grebe could be distantly seen along with at least two water pipit and near Tern hide, at least 85 linnet. An adult female marsh harrier crossed over the lake a few times and a sparrowhawk was seen trying to hunt the small starling roost int he late afternoon. The starling roost has evidently relocated having dropped from tens of thousands to a few hundred. I could also find no sign of any great white egret, even at dusk when I looked at the usual roost site, none could be found.

Part of the linnet flock on the shore beside Tern hide, there are lots of them but they are hard to pick out!

I had a look through the gull roost and there were good numbers of lesser black-backed gull and black-headed gull, but only 14 common gull, two yellow-legged gull and no sign of the ring-billed gull or Caspian gull. Obviously I could not check all the gulls present but conditions were very good, so I was disappointed not to find either species.

Away from the birds I came across an oak branch with a remarkable habitat growing across it, just one branch had it’s own forest of lichen, moss and fungi, small in scale but extraordinary.

It might be only just after Christmas, but signs of spring were to be found. I saw snowdrops pushing through the ground and the hazel catkins are opening.

I also heard singing mistle thrush and great tit as well as the year round singers like robin and Cetti’s warbler.

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 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.

Thayer’s Gull

There has been much excitement in recent days at Blashford Lakes over the sighting of a potential Thayer’s gull. I say potential because these are not easy birds to identify or at least it is not easy to know exactly what you are looking at. Larger gulls are a particularly tricky bunch, they can vary quite a lot within species and not much at all between species and (even worse) sometimes hybridise!

So how do you ever know what you are looking at? For all the species there are the “Classic” birds, the ones that look like the have just stepped off the pages of the field guide, these should not be too difficult, although some genetic studies suggest even some of these might not be quiet what they seem. The others are more problematic, at least for people who like to put a name to them. Often it then comes down to looking at the various characters and scoring what is positive and what negative, after that you can consult experts or, for the more free-wheeling just decide if you are happy or not. For some there is no “right” answer, just the balance of probability.

So is this Thayer’s gull the real thing? The short answer is I don’t know and it will probably get decided by committee in the end and some will accept the decision and others not. Having seen the bird at some distance last night and then rather better tonight I have a few observations. The books often say they are structurally like Iceland gull and a claimed one I saw many years ago in Ireland was, to my eyes, identical in structure to Iceland gulls nearby. This bird looks bulkier than what I would expect for an Iceland gull, but it has the same wide, round head so typical of that species. Iceland gulls do have broader bodies and heads than herring gulls but this bird looks very heavy indeed. The wings do not look long and the rear of the bird on the water looks less attenuated than typical for Iceland, but this may be due to the rather large body size and males gulls are often a lot larger than females. As far as I can tell the plumage looks as though it has all the expected features.

Whatever it is, it is interesting and different from any other gull I have seen before, even the other one claimed as Thayer’s. It is quite obvious in the roost, it certainly stands out as different. Another way of looking at it is what might it be if it is not a Thayer’s gull? It seems American herring gull will hybridise with Thayer’s gull and that they will also hybridise with Glaucous-winged gull producing offspring that look like Thayer’s gulls. However it seems that these various hybrids tend not to have the round head, which this bird certainly does have.

If you are a bird lister it really matters if this is or is not a Thayer’s gull, importantly if it is accepted as such by the rarities committee once they have weighed up the pros and cons. Whatever they decide it is a very interesting bird and I am pleased I have seen it, I have looked at many, many thousands of gulls and never seen one quiet like it before. There is a school of thought that Thayer’s gull is just a form of Iceland gull and not a full species at all.

All this begs the question of just what defines a species, actually an important question for conservationists as rarity often drives much funding and conservation effort. A rare species will attract more effort than attract more effort than a sub-species. The definition of a species is  not a simple thing and not as clear as you might think and subject to change. Actually what matters are populations, we need to conserve populations, it does not really matter if they are species, sub-species or separate groups of one species. Keeping populations viable ensures their survival whatever their status, we should not consider them less because they are not a separate species by the current definition.

As for the Thayer’s gull, I enjoyed seeing it whatever it is eventually decided to be. Come to that I enjoyed seeing all the other gulls in the roost too. All 9,000 or so of them, including a juvenile Iceland gull, yellow-legged gulls, Mediterranean gulls and the thousands of lesser black-backed gulls and black-headed gulls. If you are interested there are pictures of the Thayer’s gull on the HOS go birding website, mine are so bad I will not torture you with them!

Elsewhere, away from the gulls, “Walter” the great white egret was on Ivy Lake and 2 black-necked grebe on Ibsley Water along with a single Bewick’s swan, a  real rarity here these days, although there were almost 200 wintering in the valley a few decades ago.
