Eurasian Hobby: A hunter of dusk or dawn?

Abstract

The European literature considers the Eurasian Hobby Falco subbuteo as active during the day, while in the southern African literature, the species is - often exclusively - called a hunter of dusk and dawn. This note tracks down the three original sources on which this misunderstanding is based and reviews evidence for the mainly diurnal activity of this species based on European standard literature.
