Today the red male marsh harrier from Lodmoor put in an appearance after an absence of several weeks.
This is the bird that has successfully bred at Radipole and Lodmoor for a number of years now.
It is very unusually coloured, being predominately reddish-brown rather than the usual combination of dark brown, light grey and black.
Apparently these red males have been seen in Europe for a while now, but are very rare in Britain.
The theory is that they avoid aggression from other male harriers by looking more like females.
The other male around at the moment, the one that bred at Radipole last year, is this traditionally-plumaged sub-adult male.
The above video does not really show its colours very well so here's the video I got last month.
