Well, I got an expert opinion and it’s a chaffinch. I’d never have got it myself.
It is a very difficult
angle but you can make out the olive cheeks and the white in the tail
which both point to chaffinch. The position of the nest in the fork of a
tree like this is also classic Chaffinch, as is the construction.
lovely shot. I am new to nature photography myself and would be very happy to be taking photos like that. your son has a good eye for photography. hope he stays interested in the future. well done.
