Today may have been the last day of April, but it felt more like the last day of January! a bitter north-east wind was blowing hard across Ibsley Water making it foolish to open the windows at the Tern hide. The cold had brought thousands of aerial feeders low in over the water in a desperate search for any sort of flying insects to eat. At first I though they were mostly swallow and sand martin, but it turned out things were a little more complicated.
Close to Tern hide there were a lot of swallow, whilst further out over the water sand martin were the majority. Further away house martin dominated, especially close to the northern shore of the lake. All this made estimating numbers a bit tricky. In the end I “guestimated” around 4000 hirundines were present with slightly more than half being sand martin, perhaps 2000-2500, then house martin with around 1000 and then 500-700 swallow. All in all it was quite a sight, although one that featured birds that were not at all happy. Luckily the promised rain never arrived and it actually got a little brighter later on and many of the birds left to feed elsewhere. Perhaps oddly by the end of the day swift were one of the more numerous species, maybe 500 were feeding over the water, many more than in the morning.
Other sightings today included a yellow wagtail and a white wagtail close to Tern hide, from where I also saw a single black-tailed godwit, 2 common sandpiper and 3 goosander. Elsewhere 2 drake pochard were notable as was a single whitethroat, an oddly scarce bird at Blashford and mainly seen in autumn.
The moth trap contained just 2 common Quaker, moths don’t like cold, windy nights, but then who does.
