this young male Marsh Harrier was at Barton today--It is a bird I have seen several times in the last 6 weeks up the Humber but always at a distance---clearly a male from the developing underwing pattern and the greyish central tail feathers and odd coverts I have aged it as a 2nd calendar year bird entering its second winter and moulting to thrid summer, first adult male plumage
