Cambourne seems to have more than an average share of crows. One copse in particular was especially busy today and I watched for a while.
There seemed to be much territorial reshuffling going on. Every so often a pair, or three, would leave the vicinity of one nest, fly in a wide circle, then land at another nest, often nudging the incumbents to repeat the process.
Ah. Friday. Financial spreadsheets and discrepancy hunting can wait until tomorrow.
