Pennsylvania’s Owl Diversity: An Overview
Pennsylvania is home to a surprising variety of owl species, from the large and imposing Great Horned Owl to the tiny Northern Saw-whet Owl. Here’s a look at some of the owls you might encounter in the Keystone State:
Common Owl Species
- Great Horned Owl: This is the owl you’re most likely to see in Pennsylvania. These majestic birds average around 3.5 pounds, measure 19 to 24 inches in length, and boast a wingspan of 3 to 5 feet. The state considers them a breeding and common species.
- Barred Owl: Another frequently encountered owl, especially in wooded areas. Barred Owls typically measure 16 to 20 inches long, weigh up to 2 pounds, and have a wingspan of 39 to 43 inches. Like the Great Horned Owl, they are considered a breeding and common species in Pennsylvania.
Less Common Owl Species
- Eastern Screech Owl: These smaller owls come in two color variations and are usually under 10 inches long (males can be as small as 8.5 inches). Despite their diminutive size, they are considered a breeding and common species in Pennsylvania.
- Northern Saw-whet Owl: One of the smallest owl species in North America, the Northern Saw-whet Owl stands only 7 to 8 inches tall. They are also considered a breeding and common species in the state.
Rare and Migratory Owl Species
- Long-eared Owl: This owl, standing around 15 inches tall with a 40-inch wingspan and weighing about 11 ounces, is considered a rare breeding species in Pennsylvania.
- Short-eared Owl: Often found in open fields and grasslands, the Short-eared Owl measures 13 to 17 inches long with a 42-inch wingspan. Pennsylvania considers them a migratory and rare species.
- Barn Owl: Barn Owls prefer open habitats and agricultural areas. They stand 14 to 20 inches tall and have a 44-inch wingspan. Unfortunately, they are considered a breeding and rare species in Pennsylvania.
- Snowy Owl: This striking white owl is a migratory species, typically seen during irruption years when they venture south from their Arctic breeding grounds. They can grow up to 24 inches tall with a wingspan of up to 60 inches. Snowy Owls are considered a migratory and rare species in Pennsylvania.
Where do owls live in Pennsylvania?
Pennsylvania is an owl-friendly state because it offers a diverse range of habitats.
Forested Regions
Because almost 60 percent of Pennsylvania is covered in forests, you’ll find many owls there. Barred Owls and Great Horned Owls love these areas.
Open Fields and Grasslands
If you’re in a rural part of the state, keep your eye out for Short-eared Owls and Barn Owls. Pennsylvania’s farmland also makes good hunting grounds for these species.
Wetlands and Riparian Zones
Some owls hunt and nest in wetlands, where they can easily find prey. If you’re near a river or stream, it’s a good place to spot an owl.
Urban and Suburban Areas
Even in cities and towns, you might see an Eastern Screech Owl. These owls adapt well to urban life, especially if there are plenty of trees or buildings with nooks and crannies for nesting.
Behavior, Characteristics, and Diet
If you’ve ever seen an owl in person, you probably remember how striking they are. Here are some common characteristics and behaviors of these fascinating birds.
Physical Characteristics
PA owls share some common physical traits that make them skilled hunters:
- Head rotation. Owls can turn their heads as far as 270 degrees, letting them scan their surroundings without moving their bodies.
- Facial discs. The specialized feathers around an owl’s face help them focus on sounds that can lead them to prey.
- Asymmetrical ears. An owl’s ears aren’t placed symmetrically on its head, which helps them pinpoint the location of prey.
Hunting Behavior
Most owls are nocturnal hunters, which means they hunt at night. They use specialized feathers that allow them to fly silently as they approach their prey. Often, they’ll scan for prey from a high perch, then swoop down when they’ve spotted a likely meal.
Diet
While an owl’s diet varies depending on the species and the habitat, PA owls generally eat:
- Rodents
- Small mammals like voles, mice, and shrews
- Smaller birds
- Insects (especially among smaller owl species)
Conservation status and threats to owls in Pennsylvania
Like many wild creatures, Pennsylvania’s owls face a number of challenges that threaten their populations.
Habitat loss
Deforestation and urban development both take a toll on owl populations, by reducing the amount of nesting space and hunting grounds available.
West Nile Virus
The West Nile Virus is thought to have contributed to the decline of Eastern Screech Owl populations in some areas.
Collisions
Owls are vulnerable to collisions with cars and trucks, especially when hunting near roadways. They’re also at risk of colliding with power lines, which can result in serious injury or death.
Conservation efforts
Protecting existing owl habitats is crucial to maintaining healthy owl populations. Nest box programs can help supplement the natural nesting sites that have been lost. The Pennsylvania Game Commission is actively involved in these efforts.
Endangered species
Sadly, some owl species in Pennsylvania are endangered or experiencing population declines.
For example, the Short-eared Owl is listed as an endangered species in Pennsylvania.
