I wonder if the male was one of her offspring from 2007, would he fight with his mom? I'm going to poke through their logs to see if this female was around back then...

That's a good question, Carly. It's difficult to know, because the female is unbanded. The site has only mentioned that the male is new this year - easy to tell because he is banded - but I think the female is also different. Last year the female was unbanded, but she had a slight beak problem; the upper and lower mandibles didn't quite align. It was noticeable, but not severe, and did not cause her any problems eating or feeding the chicks. She also had a lot of black on her beak. This year's female has no beak problem, and not as much black on her beak. This is only my opinion, and I haven't seen anyone else mention this possibility.

Wow that was quite the fierce battle. I've never seen raptors battle before but man oh man it was unreal. Thankfully they both survived for another day. It's amazing what technology has done to capture not just the lives of the eggs but every other aspect of being the Prince of Birds.

Wow! I've never seen this kind of battle before so thank you for passing it on. A word of warning for others, it's pretty violent.

alot (not all or not all the time) is sound and fury, dominance displays if you like. If one doesn't back down, then it gets a bit hairy and there is spitting and talons etc. And yes some disputes are to the death. They are also gender specific - females fight females, males fight males.

I have always read that territorial battles are gender specific, but it seems that at the Brighton, England nest yesterday there was a territorial battle between the resident female and a new male (who was actually born at that nest two years ago). There have already been changes at the nest this year - last year's unbanded male did not return, and a new banded male from Chichester, born 2005, moved in.
TPC, I'd be very interested in your comments on this battle - it seems unusual for a female and a male to fight. There is a video on the Diary page of the site:
