Murmuration

Did anyone see the article about ‘murmuration on the BBC news website yesterday?

This is the technical term for the aerial swarms of starlings that occur immediately prior to settling into their roost site in the evening.

It’s phenomenon I’ve seen before but not for many years. I was an undergraduate in Liverpool in the mid 1980’s and I recall on winter evenings there were frequently murmuratons of starlings going on over St Johns Garden behind St Georges Hall in the centre of the city.

This is a great name for one of natures truly spectacular, and mesmerising, events. I don’t know how many birds were involved in the murmurations I saw but I believe it can be up to tens of thousands. The overhead spectacle is awesome, and in a rather different respect so is the effect it has on the pavements beneath… and the resultant stench!

The BBC article refers to some new research from two Italian biologists who studied the flocks of starlings over Rome, and using clever camera work they divined how the birds maintain the shape of the flock. There was also speculation about why they murmurate. I think it must be down to evasion of predators such as peregrine falcons.

I can’t resist the temptation to gratuitously insert one of my starling photographs here, because on an individual level aswell as in enormous swarms they are beautiful creatures. They have sumptuously iridescent plumage particularly when they catch sunlight at the right angle:


Sturnus vulgaris

Alas, I don’t have any of my own photographs of murmurations but I intend to rectify that situation in the future, at which time I will post again about these endearing creatures.
