Barn Owls are often found in rural areas near farmland and open countryside. They usually reside in the lofts of abandoned barns or silos but will also use nest boxes. Barn Owls have golden-buff markings on their wings and back, and a white chest that may be mottled with few black spots. Their heart-shaped face makes them easy to identify. Barn Owls make a variety of sounds including a hiss and a rasping screech that has been mistakenly identified as the terrifying screams of a woman. They primarily eat meadow voles and other rodents that are commonly found in farm fields. Barn Owls breed between April and early May and produce four to six young per year. Barn Owls are found throughout Maryland at any time of the year but are considered to be rare to uncommon.

The Eastern Screech-Owl lives in wooded areas adjacent to open fields and nests in tree cavities or nest boxes. Adults average around 8 to 9 inches tall and are found in two color morphs - a gray phase and a reddish-brown phase. They have two tufts of feathers called “ear tufts,” which are not actually ears but feathers used to camouflage themselves within tree foliage. Though their name implies that they make a screeching sound, their call is more comparable to the “whinny” of a horse. Eastern Screech-Owls hunt at night and eat small rodents, flying insects and small birds. Year-round residents of Maryland, they are fairly common in suburban areas.
