Egret Regret

There was quite a long newspaper article (http://www.timesonline.co.uk/tol/travel/best_of_britain/article6893929.ece) about the colonisation of the UK by the Little egret (Egretta garzetta) from foreign parts. The claim was made (true) that one of the first places they successfully bred here was on Brownsea Island in Poole Harbour. What the story didn't mention is that that breeding group was decimated by Ravens (Corvus corax) which, as an endangered UK species, could not be touched. The 'foreigners' have presumably gone somewhere else to try to raise a family. There is no doubt that the Little egrets migration north continues at a pace. Groups of them forage near the Loughor bridge at low tide.
