It's true, I quite like Pigeons
said that I'd look through my Sparrowhawk pics for any evidence of differing Nape patterns on males and female, especially juves. Also to see if there's a relationship between eye/head size and gender.
I've over 10,000 pics of Sparrowhawks, and the vast majority are of behaviour, as that's what I'm most interested in. Finding pics that show what I'm looking for won't be easy, and I don't have the time ATM. But, I thought that I'd upload 20+ pics that are of birds that I'm positive(ish) of the gender, and see if any here that are interested can see any of the aforementioned relationships. I must admit that my eyes aren't really good enough to see these differences unless there's a stark contrast, so I can see no difference in eye size. I can see differences in nape patterns, but I'll need to sort out more pics to illustrate this.
Anyway, here's a few pics to be getting on with; I only expect 2 or 3 in this forum to have any interest in this, and they need to see the thread and have the time first
Not that it matters in this case, but all pics through double glazing
Only the first pic in this group is a female
