Blackbirds sing the sun down, as well as singing it up. To my mind, this makes them threshold guardians for the passage between night and day. In quiet surroundings with a fair density of blackbirds, it’s possible to hear them exchanging fragments of melody. They have huge repertoires.
Being modestly sized garden birds, and birds of the wood and hedge, they can turn up pretty much anywhere that worms might be available.
I am entirely convinced that blackbirds also sing about the weather. Between dusk and dawn, they call individually – alarm cries when there are predators about, the odd moment of song, unless a storm is coming. They can get it wrong but on the whole their weather sense is far ahead of mine. I’ve found this reliable enough that hearing a blackbird rainsong will cause me to bring in the laundry even if I’d thought the sky was ok. They’re usually right.
When the rain, or hail, or snow has stopped, they’ll sing again for a little while.
