We didn't see the resident Osprey and neither did we see any Marsh Harriers but there was a single Buzzard, certainly 2 and probably 3 Booted Eagles and at least 3 Kestrels, including a rather splendid male.
The bird of the day arrived just before I was getting ready to be off for home, although Ann and David were staying on. This bird of the day was a female Peregrine Falcon, but not just any female but a very big one and I was able to get enough on her head plumage, along with the size, to make me pretty certain that it was one of the northern calidus race from the frozen north. Apparently on Sunday she had been seen to get in amongst a flock of Teal which unsurprisingly had a massive mass panic and dived into the bushes with at least one getting cuaght in a mist net. The female nearly got herself caught too but I imagine that the ringers (banders if you are of nearctic origin) breathed a joint sigh of relief. Dealing with an angry, rather well armed peregrine would not make my day, I did it once with an Osprey and one feels terribly vulnerable. After I had left, Dave and Ann saw it have a go at a Cormorant and the Cormorant dived straight into the water. Sensible bird as I have little doubt that the female Peregrine could have done it a lot of damage.
So, althgough unable to compete with Dave's total, I don't think that ours of 42 is too bad.
