Godwit count

Assistant editor Mike Weedon writes:
Inspired by my friend Graham Catley's big counting technique (as featured in Bird Watching, November 2006) I coloured in a pic of a bunch of Icelandic Black-tailed Godwits chased into the air by a Peregrine on the Nene Washes last Friday 30.3.07. This was one of two flocks doing the rounds. And I was quite pleased by my estimate of 1,000 birds. As you can see by the clusters of 50, there are 900 birds in this photo. (DSLR)
