I'm interested in hearing from observers in the UK and Europe how common juv. Hen Harriers are that show orangey/rufous tones to their underparts??
I understand this may be hard to quantify, but I'm interested to know if these are seen annually in the Uk/Europe or are they indeed rare color phases of typical juv. cyaneus.
Also, if anybody has photos of these type of birds I'd be interested in seeing them since these birds would be difficult to separate from vagrant hudsonius "Marsh Hawks". Forsman has some adult females in his book that are ochre-toned, but I'm concerened with juveniles, and I'd be particularly
interested to hear if any of these rufousy hen harriers always show streaking below or whether they can be unstreaked.
Do these birds show orange tones to the tail and upperwing like typical hudsonius?
Mainly for curiosity's sake, but any input would be appreciated.
