Anahuac National Wildlife Refuge, Chambers County, Texas, USA, March 2018
Breeds from Alaska east through northern Manitoba to Newfoundland and south to California, Colorado, Nebraska, and Maryland.
Northern limit to wintering range stretch from southern California to the Gulf Coast and the Carolinas; occasionally farther north along the east coast.
The main wintering range is from Florida along the Caribbean coast of Central and South America to north-west Venezuela.
Accidental vagrant to the UK and eastern Siberia.
Taxonomy
This is a monotypic species[1].
Habitat
Lake shores, flooded meadows, marshes, and streams, creeks.
Behaviour
It is the first of our swallows to reappear in the spring.
Tree Swallows often enjoy playing with a feather, which they drop and then retrieve as it floats in the air.
They gather in enormous flocks along the coast in fall, where they circle.
Breeding
Hole-nesters such as the Tree Swallow often face a housing shortage and must fight to get into, or keep, woodpecker holes or other sought-after nest sites. Man-made breeding boxes may help increase the numbers of these birds. The Tree Swallow almost invariably nests in the immediate vicinity of water. 4-6 white eggs in a feather-lined cup of grass placed in a hole in a tree or in a nest box
Diet
Insects caught on the wing. During winter, also feeds on berries.
This bird's habit of feeding on bayberries enables it to winter farther north than other swallows.
Vocalisation
Cheerful series of liquid twitters.
