Redpoll

If you fund yourself looking at a small bird with a pink breast, a red patch on its head and a small beak then you've got yourself a redpoll.  People sometimes confuse linnets with redpolls but the the two are relatively easy to tell apart with practice.

The real problem is trying to work out what sort of redpoll you have, as the species has recently been split into Common Redpolls (Acanthis flammea) and Lesser Redpolls (Acanthis cabaret).  The bigger Common Redpolls, counter-intuitively, are rare in the UK as they are native of mainland Europe and relatively few make it to this country let alone the South West.  The smaller Lesser Redpoll is the size of a Blue Tit and limited to Western Europe.  

The various bird identifying sites all agree that Redpoll Identification is "sometimes difficult" or even "often difficult".  Which just about sums it up nicely.

Given its size and location, I'm reasonably confident that this is "just" a lesser redpoll.  But even so that's a bird that has been on the red list since 2009 and which arguably requires a European conservation listing.  This particular male was in the company of two females but they didn't get close enough for me to photograph but I did manage to get a shot of one of them not so long ago here.
