Well, a pair of blackbirds (Turdus merula) have. And they've built a nest -
I always feel perversely proud when a bird chooses somewhere in our yard to nest and raise chicks. It raises the status of my unkempt garden and overgrown hedge to 'habitat'.
And I never get tired of watching a pair of wild birds rear their offspring. A common garden bird maybe, but the biology of pairing up, building a nest, laying and tending eggs, feeding offspring, which then fledge and go on to form their own breeding pairs next year, is extraordinary to me.
Expect update posts, if I can do so without disturbing the birds. I hope you like baby pictures.
