The Coots on the Murdieston Dams in Greenock are having another bumper year with at least four pairs tending chicks (including a brood of five packed into their nest). Tufted Duck numbers have risen substantially since last month - presumably due to the re-emergence of failed breeders and possibly the recruitment of this year's young (which must have been hiding somewhere while they grew to adult size). 
This evening, two House Martins twittered as they commuted over the house (presumably between their colony and the river).
