I live in a South London leafy Borough in a road lined with huge trees but it is also very developed with many blocks of flats. The last few weeks I have noticed a large flock of Greenfinches turn up, there is approximately 50 birds, I've attached a photo of some of them in one of our huge trees. I've lived here for 10 years and never seen a Greenfinch here before (we are lucky to have so many different birds but never Greenfinches). I've noticed they have decided to nest in a tree in our courtyard for the first time, at 5pm the tree is alive with fluttering of so many birds settling down for the night, it's amazing. My question is: is it usual for such a large flock of Greenfinches to change nesting sites?
In reply to Nigel O:
It is too early for greenfinches to be nesting. They also don't nest as a flock of 40 (20 nests). Pairs would build each year, as do most of species. If a tree has multiple nests, it could be multiple species and ones from previous years. Depends how well built and how sheltered as to how long nests can last. Godd that someone has greenfinches, and in such good numbers.
