Tree Swallows are found across the continental U.S. (except the southeastern corner) and Canada, and in parts of Alaska. They winter in the extreme southern US and Central America as far south as Honduras.

Tree Swallows do not eat birdseed, nor will they come to a mealworm feeder. They eat flying insects like beetles, horseflies, dragonflies, ants, moths, and mayflies. (A few people have gotten them to eat crickets or mealworms flung into the air.) Because they rely on bugs, extended periods of cold rainy weather can be deadly.

Tree Swallows consume approximately 2000 insects and feed 6000 insects to their young over a 45 day nesting period. That means that each nesting family consumes more than 300,000 insects. Since 90% of their hunting takes place below 39 feet, they are making a real dent in human pestering insect populations. ~ All About Blue Birds
