Well, the short answer is that I was wrong in 2015 (and now cannot understand how I made such an obvious mistake 3:-)) but I think I've got it right in 2018 (happy to see Tom agrees). Sorry if I...

No.1. Yes, it's possible but not at all certain. Sexing STE on plumage seems to be a work in progress (haven't got latest Forsman to hand so I may well be out of date). According to Campora &...

Without checking the original sources I recall a rough average of 5 or 6 mm per day regrowth rate for flight feathers in a selection of raptors, so just guessing at the gaps in your images (where new...

Thanks for the feedback!



Not many in my patch in the Apennines either, just the occasional prospecting immature; be nice to think they might develop a local population but I suspect food would be...

Further to remarks above on mimicry. It's complicated! The usual idea is that Pernis may be Batesian mimics of eg. Spizaetus Hawk-eagles; others have suggested the reverse, that such powerful birds...

Thanks all for responding. I'm reassured you all agree with the accipiter ID! That encourages my belief that the story I immediately visualised could be what actually happened. Indeed it is pretty...

Candidate Northern Goshawk (July, N Apennines, Italy): opinions sought

I've got a bit of a puzzle. A couple of days ago (17 July 2018) I was overlooking a wooded valley in the northern Apennines looking primarily for Honey-buzzards in flight. Just after noon I spotted...

Interesting observation! FWIW this feature seems to hold up in a very small sample of Sparrowhawks in north Italy (I have not got many adequate images!). In four birds that I'm sure are juveniles...

Hi Ken, I'm guessing you suggest this image shows an analogous lighting effect to the Sparrowhawk of the OP? On the contrary I think it tends to confirm that the Sparrowhawk's apparent colouration...
