Two Swifts were over Novar Drive, Hyndland first thing. Later, a walk along the Clyde, from Glasgow Green to Cambuslang, produced mostly common birds (Mute Swan, Mallard, Goldfinch etc), but a pair of Bullfinches were quite unusual. Cambuslang itself was swarming with winged ants - reminiscent of the "plague" of greenfly in the East Neuk two weeks ago.
