Agriculture and development have significantly diminished the colonies of prairie dogs and other burrowing animals where Burrowing Owls once nested by the hundreds. The greatest variety of subspecies is found in Central and South America. Young owls play-hunt by jumping on each other, on prey brought by their parents, and on dung around the burrow.Back to top, Burrowing Owls are still numerous, but populations declined by about 33% between 1966 and 2015, according to the North American Breeding Bird Survey. The female will lay a clutch of 4 – 12 eggs, with an average of 9 being laid.

They are found across North, Central, and South America in open areas with low vegetation. Version 2.07.2017. Burrowing owls inhabit open prairies in Florida that have very little understory (floor) vegetation. Burrowing Owls may be sexually mature at 1 year of age. They are mostly monogamous and breed close together in loose colonies. Burrowing Owls commonly hunt grasshoppers, crickets, moths, beetles, mice, voles, and shrews. The nest burrow can be several yards long and is usually less than 3 feet deep, but size depends on the mammal that originally excavated it. Different subspecies have different distribution ranges. Their diet consists of insects, mice, rats, chicks, and more. The owls often line their burrow with livestock manure, sometimes with feathers, grass, or other materials. White or light colored feathers give these birds a dappled appearance across their entire bodies. They also have a light patch of feathers on their chins that is expanded when communicating with one another. They also often nest near roads, farms, homes, and regularly maintained irrigation canals. A. and A. S. Love. 8. Unfortunately, these birds are not generalists in their habitat, and this makes them vulnerable to population decline due to habitat destruction. It is common and widespread in open regions of many Neotropical countries, where they sometimes even inhabit fields and parks in cities. Usually staying close to the ground, they fly, hover, walk, or run, seizing prey in their talons. Education is the cornerstone in building public support for Burrowing Owl conservation efforts. Burrowing owls are small owls with long legs that prefer terrestrial, or ground, living. They also prey on dragonflies, giant water bugs, earwigs, caterpillars, scorpions, and earthworms, frogs, toads, snakes, lizards, turtles,and salamanders, bats, ground squirrels, small weasels, young rabbits, songbirds, waterbirds, baby ducks, and even young burrowing owls.

Burrows tend to make numerous twists and turns, with a mound of dirt at the entrance and an opening at least 4–6 inches wide. Write CSS OR LESS and hit save. To accommodate this, the Corps places a t-stake near burrow entrances to provide a place for a male burrowing owl to sit. Male burrowing owls often find a raised place to perch in to guard their territory against predators and other burrowing owls. Partners in Flight estimates a global breeding population of 2 million, with 31% spending some part of the year in the U.S., and 15% in Mexico. The drainage of wetlands, although detrimental to many organisms, increases the areas of habitat for the burrowing owl. Disturbed owls bob jerkily up and down, as do hunting owls pinpointing prey. It is therefore listed as Least Concern on the IUCN Red List. Version 1019 Patuxent Wildlife Research Center, Bird Banding Laboratory 2019.

They use burrows dug by prairie dogs, ground squirrels, badgers, marmots, skunks, armadillos, kangaroo rats, and tortoises. The species is listed as Endangered in Canada and as a species with Special Protection in Mexico. The North American Breeding Bird Survey, Results and Analysis 1966–2015. Link (2017). Unlike some species of owls, these birds have no feather tufts on top of their heads. Pesticides, collisions with vehicles, shooting, entanglement in loose fences and similar manmade hazards, and hunting by introduced predators (including domestic cats and dogs) are also major sources of mortality. Burrowing owls are protected under the Migratory Bird Treaty Actin Canada, the United States, and Mexico. To help them survive life on the ground, these birds live in small groups called “colonies.” They live together in burrows, and just like meerkats, they will take turns standing guard. (2019). Preferred sites have loose soil, a bit of elevation to avoid flooding, and nearby lookouts such as dirt mounds, bushes, fence posts, or road signs. Habitat.
