Starlings (Murmurations) and Crows ( Cawcophany ?)
When many starlings gather together to decorate our skies, it is known as a "murmuration". See http://www.theguardian.com/environment/gallery/2014/jan/21/starling-mumuration-season-in-pictures I have seen such murmurations every now and then in the skies above Sarasota FL. They are gorgeous to behold. --------------------------------------------------------------------------------------------- The noisy crows form similar flocks. I have seen such flocks three times in the past week. This photo' is not mine. It is from Google images Crows do not create a "murmuration". That word is reserved for swallows. So I have created my own collective noun for the flocks of crows. I call them "a cawcophony of crows". (Doubtless some other "wise guy/girl" created this collective long before I).
