Starlings debating society?
A flock of starlings congregate in the sloe bushes on the way down to the river and keep up a continuous twittering, whistling and chattering for about a couple of hours in the middle of the day. Can some bird expert explain why they do this? Is it just to be sociable and perhaps form a bond within the flock? Are they staking claims to nesting sites in advance of the next breeding season? Is there some survival benefit I have not thought of?
