The blackbirds and doves like this feeder because they can balance on the tray and have a tuck in. Some of the other feeders make it hard work for them which is why I have various types of feeders for different kinds of birds. The blackbirds can manage to just about balance on the suet ball feeder so they are quite adaptable.
Thank you for getting all 3 of my photos on PP and the amazing number of Favs on my tawny owl. It is very much appreciated.
