Not a very June-like day, with increasingly strong winds and rain getting heavy by the end of the day. Not the kind of conditions to be a newly hatched, fluffy lapwing chick and not the conditions to be an adult lapwing trying to keep your chicks alive. In front of Tern hide the brood of tiny chicks I first saw yesterday turned out to be a family of three. The adults have a difficult line to tread, if they brood the chicks, keeping them warm and dry, they don’t get enough food and ultimately starve, if they let them feed they run the risk of getting wet and cold and dying anyway. So prolonged wet windy weather is very bad for chick survival, let’s hope there are enough dry breaks in the weather to give them have a chance.
Lapwing and oystercatcher chicks
As it the weather was not enough the adult lapwing are very protective of their chicks and see danger everywhere, in this case they seemed to think that the oystercatcher and her chick and the starlings were unacceptably close and needed driving off.
The oystercatcher chicks are somewhat larger now and able to cope with a bit of adverse weather. When they get to this size the adults often take charge of one chick each, watching over them and feeding them, with the chick finding a little food itself.
The poor weather brought lots of swallows, martins and swifts to feed over Ibsley Water, the numbers growing throughout the day as the conditions worsened until, by the time I closed up I estimate there were at least 1000 swifts, an amazing sight. I got a picture, but in the rain it is hard to make out the birds, I think there are probably about 75 in this shot and the whole sky was filled with them.
I was out early doing a breeding bird survey off-site this morning and when I arrived at Blashford it was to be told that I had just missed a red-rumped swallow. This Mediterranean nesting cousin of our familiar swallow occurs as a regular, but still rare, migrant at this time of year, some of them migrate north with a bit too much vigour and over-shoot their intended destinations. They usually turn up in flocks of swallows and martins at places like Ibsley Water, so it was something of a surprise that we had not got a reserve record before now. It was reported again about an hour later and I did see a bird that was supposed to be it, but I could not convince myself that it was and before I could get a better look it flew off. One that got away!
However there were lots of other birds, at least 850 mixed swallows and martins, I estimated about 400 sand martin, 250 swallow and 200 house martin. There were also at least 6 swift, although I was told there were many more. Scanning around I also saw a red kite, 2 raven, at least 8 little ringed plover in an aerial dash past the hide and lots of buzzard. On the ground I saw my first common sandpiper of the spring and a white wagtail. In addition the first summer little gull was still there as were at least 6 common tern.
The main work recently seems to have been raft related. We are building a new set of tern rafts with money from a grant given by Hampshire Ornithological Society (HOS). A few days ago we launched the prototype before we get on with building the new fleet.
Although the common tern are starting to arrive they won’t be getting down to nesting for a little while yet unlike the resident birds. In the last few days I have found nests of both blackbird and song thrush. The pictures show the differences between the two, the eggs of song thrush are clear blue with black spots, clearly distinct from the more muted colours of the blackbird eggs. You can also see the difference in the nests themselves. Blackbirds have a lining of grass whereas song thrush have a smooth render of mud that dries to a hard shell and no lining at all.
Despite another miserable, wet day, as the subject title suggests there are at least glimmers of hope that spring might be on the way!
One of these is the growing number of “pussy willows” (pictured above) whose catkins have opened and are now ready to service the needs of hungry insects including early bee’s and butterflies and even birds such as blue tits have been known to feed on this rich supply of early nectar. You can try it yourself if you want, though you may get a few odd looks; simply pop the open catkin in your mouth and suck for a little sample of the sweet nectar. Just take care to only pick “fresh” looking flowers as bedraggled, damp ones may have recently been tried by someone else reading the blog! If the weather carries on like this you may as well try a few because there will certainly be no insects to pollinate the flowers until the weather improves.
Elsewhere around the reserve there are a few other signs that spring is around the corner – chiff chaffs are in full song and good numbers of and a number of swallows were feeding over Ibsley Water today and though there are not yet signs that the martins have begun excavating nest cavities in the sand martin bank other birds are certainly “in the mood” – a pair of great crested grebes were diligently constructing a nest outside Tern Hide this afternoon and I caught a pair of tufted duck “in the act” as I opened it up this morning too.
Though far from being in full leaf the hawthorn hedges have now got a very obvious “fuzz of green” about them and other tree leaf buds are swelling and will soon be emerging too.
