I've been a bit worried of late about the relatively low numbers of Swifts and House Martins in the skies over Radford Semele.
Possibly I was a little early in expecting them. Certainly in the last couple of weeks, things seem to be picking up - on Friday night there were perhaps a dozen Swifts screaming overhead at 9pm. Still not as many House Martins as I would expect, but perhaps the numbers will improve as the young fledge.
(Mind you, based on the two pairs I saw still building nests at nearby Charlecote House this weekend, there's some way to go before any young appear. Certainly no problems about numbers mind - there were scores of Swallows and House Martins across the whole estate.)
