Light pollution causes robins in particular to sing …… here it's from 1.30ish until the early hours with a break before he begins in the day

Since Sept we have had 3 frosts so far. I usually buy 2kg live meal worms weekly but stopped in NOvember because the birds were eating them quickly enough - I did put more out on Sat. and the feeders have been emptied.
We don't have anywhere near the amount or varieties of birds that were here in the 1990s and we had 3 cats and a dog at that time.
Our wren is back, nipping around the garden pots and nagging from close by ;-)
