30 Days Wild – Day 10 – Damp(ish)

Most of my “Wildness” involved being indoors looking out, although it was not too bad at the beginning and end of the day. The office window at Blashford looks out over the picnic tables and the small pond used by education groups for pond-dipping. It was a movement on the pond-dipping boardwalk that attracted my attention as I was using the photocopier.

It seemed to be eating mainly the flowers, but the books will tell you that every part of the plant is highly poisonous. I have previously noticed that cattle seem very partial to eating this plant, apparently without obvious harm.

I ventured out at lunchtime, but only as far as the Tern Hide, but I was rewarded with an adult lapwing accompanied by a juvenile with several colour-rings. I do not know for sure yet, but I am pretty certain it is one ringed by the Waders for Real project in the Avon Valley. Given the poor success of our own birds this year I was just pleased to see a fledged juvenile.

Although the juvenile was running around feeding well and could fly very well it was still being defended vigorously by the adult, which spent sometime dive-bombing a family party of Canada geese.

Other birds around were two wigeon, a drake and a duck, but not together, a black swan, hundreds of swift, similar numbers of house martin (in both cases over 350). The highlight though was a marsh harrier, hunched down in the shelter of the vegetation on one of the islands, looking rather miserable.

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.
