"After some initial frustration with birds wriggling out of the net," Gerry reports, "I got lucky on ... with a female Siskin [left], and then I was just about to take down the net to go out when I noticed a Mealy Redpoll [below] come to the feeder, and after a few nerve-wracking moments it popped into the net."
This Mealy is clearly a male, and appears to be one of the two well-watched males which have commuted between the park and Dukes Avenue this winter. The species is a scarce visitor to the London Area, and must be a real rarity for ringers in southern England.
