Last swift left Bristol on August 3rd.

According to Mark Glanville - "Of my 3 pairs, one pair fledged around the 15th July, another pair on the 22nd and the last pair between the 23rd & 25th. The first pair that fledged, 1 adult left immediately, the other remained until the 1st August. The second pair that fledged, both adults remained, one departed on the 1st August, the other on the 3rd."

Will be interesting to see when the first are sighted in Southern Africa.
