I saw a goldfinch I think, I remember it's red face but not the yellow on the wings. Very unusual for my garden. I also have some blackbirds building a nest in the rear garden which I'm very pleased about. I don't feed the birds at all because a lot of my neighbors had cats which were regularly seen walking through, so I didn't want to encourage the birds. Now I have noticed the nest building I have also noticed less cats. Are grey squirrels a danger to nesting birds?
