Hello.I recently read about the diet of the American crepuscular swift (they build nests BEHIND waterfalls), then he was puzzled. "Isn't it all flying in the air?"??
An ornithologist I know suggested that they might pick up insects from the surface of a pond... - but I think Wikipedia is just bullshit, - and with this flightless kit, - you won't get enough, even in their Brazil.

- OK. But the distribution of flying families, which is food for the twilight swift , is nonsense in my opinion. I would like confirmation. Ornithologists did not answer me anything intelligible on their forum.

Why is that nonsense? Among the representatives of the beetle families found in the stomachs of birds (grains, staphylinae, weevils, leaf beetles, spangles), species of very small size and capable of flight predominate. There are also small and flying species among black-bodied beetles and ground beetles (especially). So during certain periods of their life cycle, it is not a problem for them to get on a flight to a haircut dinner. The same applies to bedbugs. And as for diptera, hymenoptera (ichneumonids and ants) and equiptera-God himself ordered
