We regularly see a variety of crows and rooks in the parks and we were recently discussing needing to know more about how to distinguish between these very similar birds. So I asked the interweb and found some very helpful answers. The video above, very much worth a couple of minutes if you are interested, comes from the British Trust for Ornithology website. Also this pictorial guide from Country Life magazine is excellent. But of course, then the search takes a different turn and we came across this wonderful list of collective nouns for all different bird species ... go and check out your favourites ... a parcel of oystercatchers, a squadron of pelicans and a committee of vultures.
Stay safe. Be kind. Identify some birds.
