A Full House

The poor weather over the last couple of days has brought in huge numbers of hirundines, that is swallows and martins, to Ibsley Water. there are especially very large numbers of house martin, they are impossible to count but I estimated at least 5000 today with probably 1000 swallow and at least 500 sand martin. Everywhere you looked over the water there were birds and then, scanning upward against the clouds there were many, many hundreds more. These higher birds are mostly house martin the swallow and sand martin tend to keep lower. They gather over water in an effort to find insects in weather when there are few flying elsewhere, often they pick prey directly from the surface of the lake.

The other aerial plankton feeder of summer is the swift, they mostly leave around the end of July, but a few can linger and searching through the hirundines can sometimes result in finding one and today was just such a time. Swift in September is a scarce bird, in fact in some years I don’t see one after mid August.

Other birds today included a hobby, lured in by the masses of martins as potential prey, although I did not see it catch one. The great white egret was around on and off, the ruff of the last few days was joined by another by the end of the day, when there were also 2 juvenile Arctic tern. A single black-tailed godwit dropped in for a while and there were 2 sanderling reported.

This is really not the weather for moths, so tomorrow’s planned “Moth Event” promises to be a bit of a damp squib. Today’s catch total a massive two moths! I suspect tonight may well be worse. The highlight was a fresh frosted orange, always a nice sight.

Several people mentioned the very good show of flower put on by our small patches of heather near Ivy North hide this year, in fact there at small patches of heather in several places across the lichen heath and I suspect these will expand in the coming years. All of this heather is the common ling, but we do have one plant of bell heather Erica cinerea on the reserve and this is in full flower now, somewhat after the ling has finished.

Although it is feeling very like autumn already there are still some reminders of summer out there, such as grasshoppers, I found this somewhat atypically coloured field grasshopper near the bell heather at the end of last week.
