We have been watching a Brown Falcon for about 6 weeks, she is usually agitated and quite agressive swooping over the car and calling aggressively. We (Dorothy and I) supposed she must have nested close by.
On Thursday 1 Dec 2011, we found the reason why. She has a newly fledged young bird
This is a shot of them together, she will shepherd it about often flying interference against ravens and magpies.
