Habitat destruction is a major threat to these little birds. When hunting, they choose a favorite perch and watch for any movement before pouncing to the ground after prey. Some common prey items include mice, lizards, frogs, toads, doves, termites, crickets, beetles, millipedes, spiders, and even cactus. These birds of prey feed on an incredibly wide variety of small creatures, virtually anything small enough to eat. Where their inflexibility with habitat fails, their flexible eating habits prevail. The greatest variety of subspecies is found in Central and South America. They are found in Florida, midwestern North America, Mexico, Central America, and eastern South America. Overall, their available habitat in North America has decreased significantly since the time of colonization. Distribution of the Burrowing Owlĭifferent subspecies have different distribution ranges. Some common habitats include grasslands, agricultural pastures, deserts, and rangelands. To burrow, or find previously occupied burrows, these birds require open areas with low vegetation. Unfortunately, these birds are not generalists in their habitat, and this makes them vulnerable to population decline due to habitat destruction. They specialize in hunting insects, and can even snatch them right out of the air! Hunting occurs both on the ground, in the air, and from low perches. Skilled Predators – These little creatures spend lots of time hunting for prey.Surprisingly, the only subspecies native to the United States are the Florida and Western burrowing owls. Subspecies – While all burrowing owls are considered to be the same species, there are as many as 22 different subspecies across the Americas.In this species both the male and female are the same size. For the most part, female birds of prey are larger than their male counterparts.
This means that females and males differ in some way, usually in size or color.
They also have a light patch of feathers on their chins that is expanded when communicating with one another. Their feathers are brown, and they have white or cream patches giving the appearance of eyebrows.
