This means the parents can only adapt their behavior if they can identify the sex of their offspring. Male nestling barn swallows have more brightly colored mouths than their female broodmates early in the nestling period. Sex differences in mouth coloration disappear later in the nestling period when, however, differences in begging calls develop.

[20] The preference for certain kinds of aerial insect as a food source seems to correlate with gregarious or colonial behavior versus territoriality. For birds ...
In the case of barn swallows, it was suggested that the holes were feeding traces of avian lice, either Machaerilaemus malleus and/or Myrsidea rustica (both Phthiraptera: Amblycera). [1] Hole counts were shown to be highly repeatable, and thus counts appeared to be useful measures to quantify the intensity of infestation.
The alternative genus Hirundo is the Latin word for "swallow". [7] Some authorities consider the West African swallow to be a subspecies of the red-rumped swallow. [8] Eight subspecies are recognised: [9] C. d. daurica (Laxmann, 1769) – northeast Kazakhstan and Mongolia to central south China
