Snowy Owls in New Hampshire: A Majestic Winter Sight
The arrival of winter in New Hampshire brings with it a stunning and majestic visitor - the Snowy Owl. This large, white owl is a captivating sight, and its presence in the Granite State is a much-anticipated event for birdwatchers and wildlife enthusiasts alike. Let's delve into the fascinating world of Snowy Owls in New Hampshire.
Understanding Snowy Owls
Scientific Name: Bubo scandiacus
Size: 23-28 inches (58-71 cm) tall, with a wingspan of 49-57 inches (124-145 cm)
Weight: 3.1-6.6 lbs (1.4-3 kg)
Lifespan: Up to 10 years in the wild, up to 20 years in captivity
Appearance
The Snowy Owl is one of the most striking birds of prey, with its predominantly white plumage providing excellent camouflage against the snow-covered landscapes of its Arctic breeding grounds. Both males and females have bright yellow eyes, but females are larger and have more dark spots on their wings and back. Juveniles are darker, with more brown and gray markings.

Snowy Owls in New Hampshire: A Winter Visitor
Snowy Owls breed in the Arctic tundra during the summer months, but they are known to irrupt - or move southward in large numbers - during the winter, making New Hampshire one of their southernmost wintering grounds. These irruptions can occur every few years, depending on the availability of their primary prey, lemmings.
Why Do Snowy Owls Irrupt?
- Lemmings: Snowy Owls rely heavily on lemmings for food. When lemming populations boom, owls breed more, leading to an increase in the number of owls that migrate south in search of food when the lemming population crashes.
- Habitat: Snowy Owls follow their prey, and when lemmings move south, the owls follow suit.
Where to Find Snowy Owls in New Hampshire
Snowy Owls can be found in various habitats throughout New Hampshire, including open fields, marshes, shorelines, and airports. They prefer areas with good visibility, where they can spot their prey from a distance. Some popular spots for Snowy Owl watching in New Hampshire include:
- Pease International Airport in Portsmouth
- Great Bay National Wildlife Refuge in Newington
- Odiorne Point State Park in Rye
- Wentworth-Coolidge Mansion State Historic Site in Exeter
Snowy Owl Behavior and Diet
Behavior
Snowy Owls are diurnal, meaning they are active during the day, unlike most other owls. They are also highly adaptable and can be found in a variety of habitats, from the Arctic tundra to urban areas. Snowy Owls are known for their distinctive "hoo" call, which they use to communicate with one another.

Diet
Snowy Owls primarily feed on small mammals, with lemmings making up a significant portion of their diet. They will also eat rodents, hares, and even other birds. They are opportunistic feeders and will take advantage of whatever prey is available in their habitat.
Conservation Status and Threats
The Snowy Owl is listed as Least Concern on the IUCN Red List, but their populations can fluctuate dramatically due to the boom-and-bust cycle of their primary prey, lemmings. Habitat loss and climate change are also potential threats to Snowy Owl populations.
How to Help Snowy Owls in New Hampshire
If you spot a Snowy Owl in New Hampshire, enjoy the sighting from a distance and avoid disturbing the bird. You can also help protect Snowy Owls by supporting local conservation efforts, reducing your carbon footprint, and advocating for responsible land use practices.
