Twite in flight, Lancashire, taken by Tim Melling on 25 February 2012. 'I liked the way the morning sunshine backlit their wings as they flew in to feed on weed seeds on this patch of rough ground. Ringing studies have shown that this flock are from breeding grounds in western Scotland, whereas the nearby Pennine breeding population travel to the east coast to winter' Photograph: Tim Melling/Flickr

House with amazing views in Gretna, Scotland, taken by tricky (rick harrison) on 13 November 2010. 'This is a shot of the starlings murmuration at Gretna Green, where for a couple of months in the year starlings congregate at a few locations around the country and put on amazing aerial displays where they dance and weave in their tens of thousands at dusk, before roosting together overnight (they separate out in small groups in the daytime, then meet up again at dusk). Incredibly beautiful sight!' Photograph: tricky/Flickr
