We've only got a couple pairs of swallows and house martins about but the swifts are doing great.
There are the usual yearly 3 nests from the one in my eaves to the two my neighbour has and at first I was able to enjoy the 3 pairs red arrows impressions each evening, like every year, but in the last week the 6 have become around 20. Dont know if the others are nesting nearby I assume they must be, but of a morning and evening they're wizzing around for hours. its brilliant.
The only attraction I can think is that at the back of our houses there are playing fields and presumably the hot weather is combining with this to create an excellent food source. Once the youngsters have fledged they may stick around a couple of days as a group, so I can get into double figures, but this year if the young from our 3 nests join up I could get an excellent display albeit for a short time. I wonder if anyone can throw any light on where these extras have come from?
Last year they were gone by the 5th August so i dont expect any better this year and I'm going to enjoy them while I can. Its a long wait till next year.
