The inside of a tree swallow nest A male gathering nesting material. The tree swallow has high rates of extra-pair paternity, 38% to 69% of nestlings being a product of extra-pair paternity, and 50% to 87% of broods containing at least one nestling that was the result of an extra-pair copulation.

A tree swallow attending its nest in a tree cavity. Swallows are excellent flyers and use these skills to feed and attract mates. Some species, such as the mangrove swallow, are territorial, whereas others are not and simply defend their nesting sites. In general, the male selects a nest site, and then attracts a female using song and flight ...
Begging rate and intensity varied in response to recordings of (1) a tree swallow adult landing on a nestbox and calling and (2) a common grackle (Quiscalis quiscala), a nest predator, landing on a nestbox. Nestlings increased the rate and intensity of their begging responses to both swallow and grackle stimulus sounds as time without food ...
Nesting behavior is an instinct in animals during reproduction where they prepare a place with optimal conditions to nurture their offspring. [1] The nesting place provides protection against predators and competitors that mean to exploit or kill offspring. [ 2 ]
The nest is a structure of primarily three levels: the first level acts as a foundation and is usually made up of twigs, mud, small pebbles, and in at least a few reported cases, small river mollusk shells were used; the second level of the nest is made up of grasses, finer smaller twigs; the third level of construction composing the nest is a ...
Tree swallow: north-central Alaska and up to the tree line in Canada and as far south as Tennessee in the eastern part of its range, California and New Mexico in the west, and Kansas in the centre Tachycineta cyaneoviridis: Bahama swallow: northern Bahamas: Andros, Grand Bahama, Abaco, and New Providence Tachycineta thalassina: Violet-green swallow
Cliff swallows are not common birds and to have them nesting on our vinyl-sided house is very unusual as they traditionally prefer nesting under bridges or eaves of old barns.
In general, nest complexity increases in relation to the level of parental care provided. [1] Nest building reinforces social behavior, allowing for larger populations in small spaces to the point of increasing the carrying capacity of an environment. Insects that exhibit the most complex nidification also exhibit the greatest social structure.
