Its breeding habitat is deciduous forests, often near water, across the eastern United States and southwestern Ontario.
These birds migrate through eastern Mexico and the Caribbean to southern Central America and the very northwest of South America in Colombia, western Venezuela, and Ecuador.

The numbers of these birds have declined somewhat in the southern parts of their range.
Brown-headed cowbirds lay eggs in the nests of these birds in some areas.
However, only 16% of cowbird young in Acadian flycatcher nests fledge successfully.

They wait on a perch in the middle of a tree and fly out to catch insects in flight (hawking), also sometimes picking insects from foliage while hovering (gleaning).
They may eat some berries and seeds.

They make a loose cup nest in a horizontal fork in a tree or shrub.

The Acadian flycatcher is an excellent flier; it is extremely maneuverable, can hover, and can even fly backward.
 Curiously, there is no scientific information on hopping or walking by this bird.

As of October 2015 there have been 2 records of Acadian flycatcher in Europe, the first being a bird found dead in Iceland in 1967, and the second a bird found on the beach at Dungeness in Kent, England in September 2015, the latter's identity being established by DNA from its droppings.
