Yep! and what a scrap going onI have to go so will rely on yooo hoo.

So busy trying to get recording that I've only seen bits & bobs, mostly of flying around by one or t'other!

Soooo .... who is this??  

17.49

Some more unedited just for the record from my tablet ....... hope yours is better D!

Just tweeted same clip ... who on earth is it??? Very worrying!!

Was just watching that on mine D ... males are not very faithful are they??

Thanks, Everyone, for the pics and news. Fingers crossed that the resident female wins out. As for the male, being so much smaller than the females, he just has no option but to accept whichever female wins the battle. They are not bothering to ask him for his opinion, unfortunately!

Thanks, Alan. I wonder what happens in this situation. I don't know enough about birds, sadly. Will the original female reabsorb the eggs? Will she go elsewhere and search for another nest site, one without a female in residence? And the poor male--he has to start all over again.

Alan, Does Sheffield have huge numbers of pigeons? Food for more peregrines than there are nest sites for? How do you go about getting more boxes? How large are their territories, normally?

so is the one with silver ring on right leg the mew female ( my pic earlier)?
