Back Again

I was back at Blashford after a week away in North Wales. It was a good many years since I was there and it was great to visit familiar places and some new ones too. Seeing wildlife that I don’t see at home was also good. Birds such as dipper, chough, whooper swan, black guillemot and hen harrier were all a treat.

So it was back to work today, but as if to emphasise that it is not so bad, as if I needed reminding, on the way in I saw a hawfinch which flew across the road. Opening up the Tern hide a black-necked grebe was on view. Outside the Centre two male brambling were by the feeder and from Ivy South hide Walter the great white egret and an otter. There really are worse places to work!

I was in the office for a good part for the day, there is no way to escape the after-break email backlog. This did mean that I saw lots of people coming and going from the Pop-up cafe, which did a good trade despite it being quite q quiet day for visitors. If you want the chance to sample the splendid homemade cakes on offer there are just two more opportunities this winter, they will be back on the first and third Sundays in March and then taking their break until next autumn. It is a testament to the quality on offer that some of today’s customers were returnees who came in just for the cake and did not even visit the reserve.

There was one negative event to report, a car was broken into int he main car park, although nothing was stolen. Although a very rare event at Blashford, with well under one break-in a year it still pays to be careful. Just as in the New Forest car parks you should obviously not leave valuables on display, but also don’t put them in the boot in the car park, if you are being watched this just shows the criminal where to look and that there is something to steal. Either don’t leave things in the car or put them out of the way at a stop before you arrive to park. If you see anything or anyone suspicious let us know, note down a car number or anything else that might help. The reserve has always been very safe and we would like to keep it that way.

Locking up at the end of the day it was evident that there was no otter around Ivy Lake, the ducks were looking very relaxed, in stark contrast to their demeanour in the morning. Although we might think of otters as fish eaters they are far from averse to duck and locally they seem to favour signal crayfish when they are abundant.

Evening on Ivy lake, peace and quiet.

The cormorant have returned to roost in the trees around Ivy Lake after going elsewhere for a while, although they are only using the ones on the spit. I also noticed that “Walter” had come back to roost in his favoured dead alder tree, if you look closely you can just make him out as a white spot on the right hand side of the picture. I expect he will be heading back to France soon, he rarely stays into March and often goes in January. Hopefully he will be back in the late summer, but as he approaches his fifteenth year of life he is a grand old great white egret now and at some point we will not see him again.

At the very end of the day the gull roost included the ring-billed gull, a couple of Caspian gull, but no Thayer’s gull, despite it having been seen flying south over Alderholt for the day spent feeding in pig fields at Tidpit. It has evidently found an alternative roost, perhaps in Christchurch Harbour.

Wetlands

This week has been busy working with volunteers at both Blashford Lakes and Fishlake Meadows. Both are wetland sites, rich in wildlife and the tasks have been aimed at maintaining this diversity of habitat and wildlife. The value of many wetlands lies not in the water itself but what grows in it or immediately around it and how these species and habitats interact. They form a mosaic including open water with lush marginal vegetation, these plants act as the support for a huge foodweb, although it is often only those species such as reed warbler or marsh harrier near the top that we notice.

So what were the volunteers up to? on both Wednesday and Thursday each team was managing scrub willow, to recreate open areas, allowing in light and restarting the habitat succession. In the past such work might have accompanied by a roaring bonfire, something I moved away from a good few years ago. I have several reasons for avoiding fires, they pollute the atmosphere, they sterilise the ground with their heat at the fire site, the ash acts as a fertiliser for hungry plants like nettle and thistle and the twigs and branches burnt are potential habitat for lost of species. For years we left log piles for beetles and other wood boring species, but the smaller diameter branches and twigs were ignored, despite the fact that they support even more species. So now we avoid fires and use dead hedges wherever we can. Ultimately the wood will break down and the carbon in it be released, but much more slowly and only after use by many other species.

At Blashford Lakes the terrain was a little drier and the areas opened up will support a mixed reed and dry fen vegetation, there is also an additional reason for clearance as this habitat is favoured by adder at Blashford. Many adder populations are in trouble, with some rarely producing young, luckily Blashford’s adders seem to be doing well and we see young snakes quite regularly.

At Blashford we have combined the clearance of small willow with pollarding of larger ones to keep some dense willow growth favoured by many species. The dead hedges here provide valuable wind breaks for lots of wildlife including snakes and log piles placed in shelter are used for basking.

As it happens today is “World Wetlands Day“, this year’s theme is “Urban Wetlands – prized land, not wasteland“. Blashford Lakes is perhaps not an urban wetland, although it is not far from the town, but it is a prized wetland developed from a former industrial site, used for gravel extraction and making concrete products. Fishlake is perhaps a suburban wetland rather than a truly urban one, it is certainly right on the doorstep of Romsey town. In many ways it had been something of a wasteland since the abandonment of farming, but a “wasteland” that nature has reclaimed in a spectacular manner and well on the way to becoming a prize wetland site.

At dusk yesterday I was struct by just how valuable wetlands are for wildlife, from Ivy South hide I could see close on a thousand wildfowl, scattered all across the lake.

A little later still on Ibsley Water the huge gull roost emphasised how much wildlife depends upon wetlands, in this case as a roost site, as most of them spend the day feeding on farmland out on Salisbury Plain.

Although the Thayer’s gull of last Sunday has not returned, this week has seen regular sightings of the regular ring-billed gull and on Wednesday and Thursday evenings a juvenile Iceland gull.

 

Preparations for Spring

It was a properly frosty morning, but walking round to open up the hides this morning signs of approaching spring were everywhere.

The snowdrops near the store are well out now and primroses are flowering around the car park edge, near the Woodland hide the leaves of the wild daffodils have been up for  a while, but now the flower buds can be seen. Along the path sides shiny, bright green wild arum leaves are showing everywhere and near the alder carr there are the brilliant red spots of colour provided by scarlet elf cup fungi.

As it was Tuesday we had a volunteer task today and we were also looking forward to the warmer days. Our task was clearing back the path sides on the way to the Ivy South hide to open up sheltered scallops to give something of the feeling of a woodland ride. This path runs almost exactly north-south and so has many sun-traps beloved of insects and reptiles. Out plan was to create more such spots in the hope of making more encounters with these creatures later in the year.

Cleared path sides to create sunny “scallops”.

The end of the day saw rather fewer birders at the Tern hide hoping for a sight of the Thayer’s gull, they were disappointed again. There was the usual ring-billed gull, several yellow-legged gull, a first winter Caspian gull and an adult Mediterranean gull in the roost. My own sightings were rather few, “Walter” our great white egret was fishing in Ivy Lake and on Ibsley Water 2 shelduck and 3 oystercatcher were the most interesting records.

Tomorrow we are working at Fishlake Meadows again, clearing cut willow into dead hedges to create new views across the reedbeds and pools.

 

Listing, Lessons and Speculations

Like lots of people who look at wildlife I cannot resist keeping lists, not usually very thorough and I usually lose interest in about mid-February each year. So far I have kept going and find that I have seen 116 species of birds so far this year, all of them in Hampshire and at least 105 of them on visits to Hampshire and Isle of Wight Wildlife Trust reserves.

Of the 116 species I can see that five of them are introduced alien species (Canada goose, Egyptian goose, Mandarin duck, pheasant and red-legged partridge) and another an introduced population of a former native (greylag).  All of these  have been either introduced for “sport” or escaped from parkland collections.

Of the native species I am struck by the many species that have changed their status radically since I arrived in Hampshire. There are various reasons for this, the white trio of little egret (now breeding), great white egret (soon to be breeding here?) and spoonbill (perhaps likewise), have increased in number and range right across western Europe. The same could be said for Cetti’s warbler, avocet, yellow-legged gull and Mediterranean gull.

Birds of prey have increased, more or less across the board and seeing red kite, marsh harrier and peregrine is not now especially notable and buzzard has spread right across the county rather than being a New Forest bird. All of these species have benefited from a more benign environment, in which they are less exposed to harmful chemicals and suffer less persecution, at least in lowland England. One other species has gained from the same change is the raven, which now nests across most of the county. Goshawk has also colonised the county and benefited similarly, although the population is of escaped , or released, origin.

When I first came to Hampshire in 1978 there was no accepted record of ring-billed gull and I am not sure there was even such a thing as a Caspian gull thought about.

I estimate that if I had been doing the same thing forty years ago my list would most likely not have included at least 14 of those I have seen this year, so more than 10% of my list are birds that would have seemed remarkable then. Of course there would have been some species that I would have expected to see then by mid January, that we have now more or less lost, or at least which now need more particular seeking. For example Bewick’s swan, white-fronted goose, grey partridge, willow tit, corn bunting, yellowhammer and tree sparrow.

So listing may well be a rather pointless exercise in many ways but reflecting upon my list so far certainly tells a story of how much has changed and of course makes one think how much might change in the future. So what might a list in another forty years include?

I suspect we will have established populations of additional alien species, most likely is ring-necked parakeet (I suspect this will happen quite soon), but I think black swan may also get a firmer foothold too and Egyptian goose could become very common. Who knows perhaps even sacred ibis could make it over here in time if the continental populations develop uncontrolled.

Natural colonists that look like becoming regulars include, cattle egret and glossy ibis, both already occasional visitors. It is interesting to note the preponderance of wetland birds that are expanding their ranges. A bit of a wildcard might be the potential for a whole range of essentially  Pacific Arctic species to turn up as winter vagrants. The ice melt along the northern coast of Russia has opened up a route for many previously unconsidered species. The occurrence in Europe in recent years of slaty-backed gull hints at the potential for species to come via this route in years to come.

Unfortunately I think a lot of species are going to get much rarer. Coastal species will be under particular pressure, in forty years time there will be little or no saltmarsh along most of the Solent shoreline and much reduced mudflats, so wintering coastal wader populations will surely be much reduced. Couple this with and increase in “short-stopping”, which means that wintering birds coming from the north and east just don’t come so far in the increasingly mild winters. Overall I think it certain that the Solent will not be nearly so significant for wintering wetland birds.

This discussion of change is only considering the winter, our breeding birds could be in for at least as great a change, who knows I might speculate on this in a later blog.

 

Hedges, Terns and Starlings

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

P1090448

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

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

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

Re-coppicing the willows around the car park.

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

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

P1090451

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

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

Just the Job

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

start

At the start

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

end

At the end of a couple of hours work

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

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

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

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

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

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

New Years Day – Listers, Cakes and a Wolf Moon

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

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

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

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

The first flower – primrose

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

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

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

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

A Cold and Frosty Morning

Ivy Lake from Ivy South hide

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

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

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

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

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

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

A Fishlake Wander, Recent sightings and Festive Opening

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

P1090322

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

mistletoe at Fishlake

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

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

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

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

 

A Returning Visitor

Not a great day to be out and about, the temperature topped out at 4 degrees and it rained throughout the daylight hours. As a result the reserve was quiet, at least for visitors, there was a good range of birds about though. All the usual wildfowl were seen, apart from either of the pink-footed goose, although it might have been there as some of the geese were lurking behind the islands.

The woodland was busy with redpoll and several bullfinch much in evidence. The nyger feeders are starting to attract siskin and goldfinch already, so I think we might be needing considerable extra supplies before the winter is out, they don’t usually start feeding on these feeders in numbers until well after Christmas.

The peak time to be out was at dusk, the starling roost was again well over 25000 birds, mostly arriving from the north, although they did not perform for long before going to roost, perhaps conserving their energy with a cold night ahead. The gull roost included a ring-billed gull for the first time this winter. I think it was the returning adult that has joined the roost over the last few winters. I managed to get a few rather poor shots of it, typically it was not playing ball, mostly facing away from me.

This picture does show the pale grey mantle and narrow white tips to the tertials and scapulars. On a common gull these are much more obvious, being both broader and contrasting more strongly with the darker grey mantle of that species.

This picture shows the heavier ringed-bill than common gull and the pale iris, most common gull have a dark iris (although a few do not, so this is a character not to be used in isolation).

Last of all and when it was almost completely dark, I saw “Walter” the great white egret roosting in the dead alder beside Ivy Lake.
