Peter and I are monitoring clinical science and WEber from the ground regularly because of the ravens.
We were down there this afternoon. A merlin or coopers hawk landed on the south east corner of Weber building and was ushered out by the male.
Then a half hour later the male was still sitting on his letter and we were waiting for nest exchange. I then saw ,coming flying in, a female peregrine. I thought ,what is MIss Edmonton doing there. Not......It was an intruder . Dad chased after her and on her first time around building ,Miss Edmonton came out of box and started cacking and she chased after it also. Miss Edmonton then came back and sat on the W , and the male pursued the female and chased it off. Peter saw it fly way north. The male then swooped a bit and then went into box. We are monitoring closely because we should soon have babies here. Hope the intruder got the message
