European Nightjar feeding habit

ZiegenmelkerWhen the sun has set and dusk turns to darkness, a discreet purring is heard often over the heath in Brandenburg´s landscape south of Berlin. The rhythmic purr of the Eurasian or European Nightjar (Caprimulgus europaeus) is increasing in volume in the background. The time lags between the purring of the Nightjar become shorter more and more. Finally, the male begins to patrol its territory. Slow, excessive wing beats enhance the impression of a relevant actor in the night theatre. It is beautiful to admire the white spots on the tail edge and the primaries. Only a few moment, this event takes place; then the Nightjar has disappeared already in the adjacent ash grove.

After consultation with an ornithologist specialized in African Continue reading Little Greenbuls fly catching insects in the rain
