Today started with another sighting of the elusive Cardonald House Martins (again just one bird over Cardonald Gardens).
The Mute Swan flock at Langbank numbered about 50-100 birds this afternoon. It is quite a spectacle with birds strung out just offshore for about half a mile. Must try to find out the history of the flock. Presumably counts have been submitted to the Clyde Bird Report.
News from the web is of successful breeding of Little Bittern in southern England (hard on the heels of last month's Purple Heron success). All of which begs the question: Why are herons doing so well? Cattle Egrets have colonised south west England, Little Egrets are commonplace (with evidence, this week, of a post-breeding dispersal reaching southern Scotland). Is it something to do with climate change - or better breeding success further south, forcing northwards expansion? And why just herons?
