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.

30 Days Wild – Day 19: Too Hot for Walking

I was down to do a guided walk at Blashford in the morning, but it was so hot that two of the walkers cried off and all we managed was a short amble along the Dockens Water to Goosander hide. At least going through the trees by the river was a bit cooler and the Goosander hide was quite busy with a fair few sand martin coming into the nesting wall. There are also now hundreds of greylag and Canada geese on Ibsley Water, come to moult their flight feathers on the relative safety of the open water. Unlike ducks, geese become completely flightless for quite a while when they moult so they have to seek out somewhere safe, but also with accessible food.

On the way to the hide we saw a few bee orchid and several butterflies, including a couple of summer brood comma, my first small skipper of the year and a few marbled white. One of the participants on the walk told me that they are also known as “Half-mourning”, something I had not heard before.

Sometime ago I posted that we had some puss moth caterpillars, they were quite small then, but now they have grown a lot and today I was dividing them up into three groups to make it easier to keep up with feeding them. They are very fine caterpillars and get ever more so with age.

Row, row, row your boat

As yesterday was so gloriously sunny, our Young Naturalists enjoyed a day exploring the further reaches of the reserve and finishing off a fun task started back in January at our volunteer get together.

We began the day though with our usual rummage through the light trap, where the group were thrilled with a good selection to identify, their best so far this year. Our haul included the following: white ermine, cinnabar, treble lines, poplar hawkmoth, common marbled carpet, marbled brown, orange footman, common white wave, angle shades, light brocade, brown silver lines, common pug and marbled minor. Here are a few photographs taken by Young Naturalist Talia Felstead:

It was then time to undertake a practical task with a difference, the lining of the coracle made earlier in the year at our volunteer get together. Coracles are small oval shaped boats traditionally used in Wales, but also in parts of western and south western England, Ireland and Scotland. Designed for use in swiftly flowing streams they have been in use for centuries, primarily by fishermen.

The structure is usually made up of a framework of split and interwoven willow rods, a material which we have plenty of here on the reserve, so it seemed silly not to take the plunge (literally) and attempt our own Blashford coracle.

The group were up for the challenge of finishing it off, cutting a slightly less traditional liner out of some left over pond liner from Testwood Lakes – thank you Testwood! This outer layer would have originally been an animal skin, covered with a thin layer of tar to make it fully waterproof. Today this has been replaced with tarred calico or canvas, with the Blashford way being whatever we could lay our hands on. So pond liner it was!

We carefully cut the liner to size, before Bella came up with the idea of looping cord through slits cut in the liner and weaving it in and out of the liner and willow rods. It was then time to take it down to the river for the all important will it float test…funnily enough no one else was brave or silly enough to give it a go:

Excitingly, it floats rather well, I think to the disbelief of some of the Young Naturalists, and possibly volunteers! So now we can get cracking with the rest of the flotilla…with plans already in place for a coracle themed Wild Day Out for the older children in the summer holidays.

After lunch we headed over to the northern side of the reserve on a wildlife hunt. We quickly spotted large numbers of Common blue damselflies sunning themselves on the gravel, moving a little further ahead as we approached them:

We headed up to Lapwing hide where on entering we were greeted with this view of a Canada goose with seven goslings:

We stayed for a while, spotting a couple of herons, a little grebe and watching a Common tern fishing over Ibsley Water before perching on one of the posts:

On our way back, Edie somehow spotted this Elephant hawkmoth in the long grass to the right of the path:

Finally, our last wildlife spot was this Beautiful demoiselle, which perched beautifully for a photo:

Words and Birds

Hello again.  It’s been a while (three weeks) since I posted on this blog, having been away and then, last week, after spending a time trimming back seed heads from buddleia to prevent them overrunning the reserve, and afterwards not feeling inspired enough to write anything.  I was berated, earlier this week,  by one of our regular volunteers and reader of the blog (you know who you are!!!) for not writing anything last Sunday, so I thought I’d better make an effort today.  Those of you who do any writing will probably recognise the problems of either  not feeling they have anything to say and/or struggling to find the words.     Along those lines,  I remember the tale of one professional writer who couldn’t think of a particular word for two weeks – but then it suddenly came to him….’fortnight’!!!

Having said all this, I guess most of you will want to read some news from Blashford, so here goes.

The bittern(s) is still in being seen regularly from Ivy South Hide, but has also been viewed, in its more usual habitat, in the reed beds outside Ivy North Hide. Whilst closing the reserve last Sunday,  I was lucky enough to catch a glimpse of this bird in the left hand side of the reeds, far off to the right side of the Ivy North Hide. As no one else has posted any pictures of this bird yet, I’ll start with this rather poor, distant image, taken in low light conditions ( getting all my excuses in first!!)  as evidence that the bird is here. P1460717 bittern Recent addition to the avifauna n the form of a ferruginous duck reported yesterday from Ivy South Hide. Otherwise the red-crested pochard is still around as are good numbers of many of the other ducks such as  mallard, shoveller, gadwall, wigeon, teal, pochard, goldeneye and tufted duck. A few green sandpiper  are scattered around the margins of the lakes.

For the gull fans (I know there are a few of you out there) up to nine yellow-legged gulls were seen coming in to roost on Ibsley Water yesterday.  Roost time can also produce increased numbers of goosander as they fly in from the Avon Valley to spend the night here.  Also in residence in and on the water, in roughly decreasing size order, we have mute swan, Canada goose, greylag goose, Egyptian goose, great-crested grebe, lapwing, coot, moorhen and little grebe. 

The alders are providing enough food to keep a regular flock of siskin in and around the Woodland Hide area.  This abundance of natural food means that many of the  winter visitors to our seed feeders haven’t yet put in much of an appearance although some lesser redpoll have been reported.  otherwise the usual collection of tit species including marsh tit as well as nuthatch and treecreeper are being seen from the Woodland Hide.  A water rail was seen, by some lucky visitors,  feeding on a fish (the rail feeding, not the visitor!), just outside the Ivy South Hide for about twenty minutes in the mid-afternoon.

A party from an RSPB local group have chosen Blashford for a day trip. One of the party reported seeing a large bird of prey flying low over the heath and going into the trees, from the description one of ‘our’ buzzards.

To finish here is a picture of what must be one of but maybe not the last ‘summer’ flowers to be seen on the reserve

The End of the Picture Gremlins

scarce merveille du jour

Here it is at last, that moth picture that would not load, the gremlins have hopefully ben banished.

A fine day at last today, but of course it was Thursday so it was perhaps to have been expected. Seventeen volunteers came out and we were once again pulling ragwort along the eastern shore of Ibsley Water. We have not been able to do the grassy promontory between the Goosander and Lapwing hides as the lapwing there has at least two chicks, the only ones I have seen on the lake this summer. We made good progress north towards the Lapwing hide and on the way saw a variety of insects including marbled white, meadow brown, emperor dragonfly, mint beetles, a white plume moth and lots of cinnabar moths and their caterpillars.

Having lunch back at the Center int he by now very warm sunshine it was again insects that caught the eye, a cream spot ladybird on the table was first for a picture.

Dragonflies are still rather few and even damselflies are not as numerous as would normally be expected. The large red damselfly is usually the first species seen in spring, sometimes from late March and they usually are over by the end of June, so to see several still flying around now was perhaps an indication of how late the season now is.

The damselfly was beside the pond and just below it was a young toad, not one of the tiny ones just leaving the ponds but an older, but still sub-adult one.

The surrounding vegetation offers various chances for sun-loving insects to bask and on one leaf a young dark bush cricket was catching some sun.

Looking at Ivy lake as I locked up the hides it was clear that a fair few of the common tern chicks have now moved away from the colony, although they have been replaced by other newly fledged ones, I think at least 25 have now flown and several are still on rafts still too small to fly. I also increased my record count of mute swan to 38. The arrival of a flock of mute swans is a new thing for this lake as the pair that used to occupy it would never tolerate incomers, their replacements are just not able to keep the hoards away. There are also two broods of Canada geese on Ivy Lake, this despite that fact that none nested there, these seem to have walked in from Rockford Lake.

The adult geese are all flightless now having dropped all their primary feathers and will regrow them at the same time as the goslings grow theirs, so all should become able to fly at pretty much the same time.
