- The eastern screech owl is the smallest of the tufted owls in our area. The ear tufts or horns on the top of the head are not truly the owls’ ears. The tufts are used for communication and camouflage. The ears are actually hidden under the feathers.
- A cavity nester, the screech enjoys all the nooks and crannies of old apple orchards. They will use nest boxes.
- The screech owl does not make a screeching noise. Their vocalization is more of a high pitched trill. They also make a high pitched whinny sound.
- The eastern screech owl can be gray or rusty red in color. They gray phase is more common that the red with only about 1/3 of the population being red. An occasional brown color will be found in our area.
- Owls can turn their heads about 270 degrees in either direction due to the 14 vertebrae in their necks. This is necessary due to the fact that their eyes are cone shaped to let more light in and are stationary in their heads.
- An owl’s hearing is exceptional and is a primary hunting tool. One ear is lower on the head than the other to allow for triangulation, which allows the owl to pinpoint their prey more efficiently.
Tips for Walk Leaders:
- Screech owls are common at Beaver Meadow Nature Center.
