Urban birds eating insects on cars – A call for observations


Urbanization causes insect declines, an import food source for birds especially during the breeding season. Some species can use insects stuck on cars (i.e. as a result of collision) as an alternative food. In Finland, this behaviour seems to be common only among House Sparrows, and not so many observations have been made on other species such as Pica pica, Corvus corone corone and Corvus monedula.

I would be very interested to know how widespread is this phenomenon, and which species are involved, at a global level. I am therefore asking for relevant observations from the ornithological community.

I would be very grateful if you could send me any information on such behavior by adding your observations online at https://cutt.ly/Rwcxck1e
