One of our blackbirds was pulling up worms when I went out to hang the washing this morning. He carried on regardless then decided he'd had enough of me in his garden and started to grumble at me, so I told him he'd have to share the garden, it's mine too. Then he came and sat on the fence right near me, carried on telling me off and glaring at me, then flew on to the shed roof and sat there until I went in.
He was obviously defending the nest and feeding his young but he was very vociferous, wasn't a bit scared and wanted to see me off!
All best wishes to Bertie
