Fun Tree Swallow Facts For Kids
Gallery
Tree swallows are migratory birds and nest in isolated pairs or loose groups. They are known as aerial insectivores as they feed on insects while being airborne.
Tree swallows can be found in North America during spring, summer, and fall. Their nest sites are found in fields or marshes near water bodies. Tree swallows have their own song, which can be heard clearly during the summer months.
It is a sweet chirping call. During the winters, they migrate to the south.
Tree swallows sing in three parts – the whine, the chirp, and the gurgle. The first one is a chirping call made by females during copulation – or by both males and females while interacting with the nestlings – and by the males when they leave or enter the nests.
The whine is an anxiety call and can be made to announce danger or predators. The gurgle comes at the end of the song, and it is said twice. It is an indication of pair bonding.

Tree Swallow Interesting Facts
What type of animal is a tree swallow?
A tree swallow is a kind of bird that is found mostly in North America and the Caribbean. Tree swallows are migratory birds known for their songs and brilliant colors.
What class of animal does a tree swallow belong to?
The tree swallow belongs to the Aves class of animals. It lays eggs like most birds in its nest sites which are present in open areas near water.
How many tree swallows are there in the world?
According to some calculations, there are about 19 million individual tree swallows in their natural habitats. Tree swallows are not an endangered species right now, but the population could be declining due to loss of habitat and human encroachment, especially the spots where they are wintering.
Where does a tree swallow live?
Tree swallows are found in Central and North America. They will travel northernmost only until there are trees and water.
They are migratory birds and winter, mostly in the southern regions of North America, which includes Florida, the Caribbean coast of Central America, and the Gulf Coast towards Panama. Tree swallows nest in tree cavities in their habitat region.
In and around cities, they are more than ready to accept nest boxes as their preferred habitat. Tree swallow nest is prepared from mud which is lined with feathers to provide insulation.
This nest is quite different from the traditional nest prepared by a sparrow which is prepared from bark strips, twigs, and weeds that is insulated with hair and feathers. But if given a chance, a sparrow will readily take over the nest of a tree swallow.
What is a tree swallow's habitat?
The tree swallow habitat is in open areas, near a water body. They are found in marshes, fields, shorelines, meadows, wooded swamps, and beaver ponds.
They build their nests in hollow trees or any such cavity. Mostly found in holes excavated by sapsuckers or standing dead trees, in artificial nest boxes, or under a building. In their natural habitat, tree swallow nests can be usually found in abandoned woodpecker holes in dead trees.
In urban areas, they take well to nest boxes. If you wish to install a nest box for tree swallow, make sure that it faces the northeast direction and is placed around 5 ft (1.66 m) from the ground.
Who do tree swallows live with?
They live in pairs or loose groups. The tree swallow is a social bird and may form a flock of thousands of birds for a nighttime roost. Swallows are highly territorial especially around the time when they breed.
How long does a tree swallow live?
The tree swallow lives for up to 11 years. The average life span is around 10 years. The survival rate for an adult tree swallow is 40-60% on average. The oldest one found was around 11 years old.
How do they reproduce?
Tree swallows are monogamous birds. Breeding pairs are formed once the females arrive in spring at the breeding sites.
They may also do extra-pair copulation as many nests may contain babies which are not fathered by the resident males. The breeding season of a swallow is between May and September, and one brood a year is raised by each pair.
The pair will nest solitary, but it is observed that they build nests close to other pairs. The females will start with the nest building in late April or early May.
The nest is lined with grasses and feathers from other birds. The females will take a few days to two weeks to build a nest. Then she will lay two to eight tree swallow eggs, one each day, and incubate them for 11-19 days in the tree swallow nest or tree swallow house.
For the first three days, the female will take care of the altricial nestlings. Both parents will feed and forage for food for their babies.
They fledge 15-25 days later and are ready to fly. The parents will continue to feed the kids after they have left the nests for three days.
The chicks can breed next season if they find a suitable nesting spot. At first, during courtship, the male may attack a female, and the female may respond back with a wing fluttering fight which is considered to be an invitation to court.
What is their conservation status?
Tree swallows have a stable population, with around 20 million individuals in the world, which justifies the fact that it is classified as of Least Concern by the International Union for Conservation of Nature.

They will feed from dawn until dusk on flies, beetles, and ants. Sometimes they feed on mayflies, stoneflies, spiders, mosquitoes, caddisflies, and grasshoppers. Unlike other similar species, tree swallows eat bayberries, bulrushes, and other seeds if the weather conditions are not suitable.
The known predators for a tree swallow are black rat snakes, American kestrels, chipmunks, American crows, and raccoons.

The tree swallow's nests
They build their nests in hollow trees or any such cavity. Mostly found in sapsucker-excavated holes or standing dead trees, in artificial nest boxes, or under the eaves of a building.
They may also build hollow nest stumps over water, fire hydrants, steel drums, holes in-ground, or holes dug by other birds like a woodpecker. The nest is made of mosses, grasses, aquatic plants, and rootlets and lined with feathers from other birds.
The females will take a few days to two weeks to build a nest. The nesting spot is decided by the males and shown off to the female before copulation happens.
How does the tree swallow compare to other swallows?
Tree swallows usually stay in cavities that are usually made by woodpeckers or tree boxes. They also have an iridescent back and a white underside. On the other hand, a barn swallow stays in mud nests, in open fields. They also have a dark blue back and a deep red throat and forehead.
When you compare barn swallow vs tree swallow, it is evident that the barn swallow is larger in size as compared to a tree swallow. Moreover, barn swallows use mud to prepare the nests that are placed along a supporting structure, while tree swallows used woodpecker holes in dead trees for their nests.
In terms of similarities in appearance, the northern rough winged swallow exhibits a remarkable similarity to the tree swallow.
