The cave swallow measures 12 to 14 cm in length and weighs 19 g on average. The largest of the five subspecies, P. f. pallida, has an average wing length between 107.0 and 112.3 mm; the smallest subspecies, P. f. aequatorialis, has an average wing length between 93.0 and 93.5 mm. Differences between the sexes are minimal, both are similar in size and weight and are difficult to distinguish ...
The nests of Aerodramus swiftlets are constructed with saliva as a major component. In two species, saliva is the only material used, and the nests are collected for the famous Chinese delicacy 'bird's nest soup', the over-collection of which puts pressure on the swiftlet populations.

The nesting sites can be vulnerable to predation by other cavity-nesting bird species, such as the house sparrow. [4] [5] These birds will search a number of swallow nests for the perfect place to make their own nest, destroying numerous eggs in the process. [4] Nests, especially those at the periphery of colonies, are vulnerable to snake ...
Many if not all species are colonial nesters; some build their nests in high, dark corners on cave walls. Swiftlets in temperate zones do migrate, but most Aerodramus swiftlets live in the tropical Indo-Pacific region and do not migrate. These birds usually remain in one cave or other roosting/nesting site.
To add to this, even birds who will nest in houses don't all enjoy the same type of house. For instance, many owls prefer a nesting box versus a traditional bird house. If there's a specific bird ...

Nesting in colonies in caves, oilbirds are nocturnal feeders on the fruits of the oil palm and tropical laurels.
