Starling (Sturnus vulgaris). During the winter months, the numbers of Starlings present within Britain and Ireland are swelled by the arrival of individuals from breeding populations located elsewhere within Europe. The numbers arriving vary from one winter to the next and are influenced by weather conditions on the Continent. Wintering Starlings roost communally and vast flocks may congregate at favoured sites, typically performing amazing aerobatic displays (known as ‘murmurations’) before dropping into the roost, which may be a reedbed, a group of conifers or a human structure, such as a pier. With many thousands of birds using a roost there is the potential for nuisance, their droppings fouling the ground beneath and around the chosen site.
These vast flocks have more humble beginnings, with small flocks of Starlings coming together as dusk approaches. Gradually, as more and more birds join the gathering, a huge pulsating flock is formed. As the light begins to fade so part of the flock will plunge down towards the chosen roost, almost as if testing its nerve to see who will be the first bird to drop into the roost itself. The birds have good reason to be nervous; these large gatherings attract the attentions of predators like Peregrine and Sparrowhawk. Photo by Nick Dobbs, Bournemouth, Throop Mill 09-03-21
