11 Types of Eagles in Maryland

Golden eagles are rare in Maryland. They are occasional winter visitors, traveling south from breeding grounds in northern Canada and Alaska when cold weather restricts their hunting range. A golden eagle in Maryland is a notable sighting and birders often share reports on local birding networks when one is confirmed. Golden eagles are all dark brown or bronze with a golden tinge on the head and neck of adults, and they lack the white markings that define bald eagles, making them straightforward to tell apart once you know what to expect.

Juvenile and immature bald eagles look completely different from adults. Young birds have dark brown heads and bodies with no white markings for several years. During their first year they are dark all over. By age two or three they may show some white patches on the body, and by age four or five the distinctive white head and neck develop. This transformation means that winter flocks at places like Conowingo are a mix of ages, and knowing the age classes helps you count and enjoy the full population rather than assuming all brown eagles are a different species.

Bald eagles are distinctive once you see them but can cause confusion at a distance. They are much larger than most raptors, with broader wings than falcons and a longer neck than most hawks. In silhouette they have a straight leading edge to the wing rather than the angled or hooked shape of smaller raptors. Bald eagles are often mistaken for large vultures or even hawks by people unfamiliar with the size and shape, but vultures have a different head shape and fly with a slight dihedral (wings held slightly above the horizontal), while eagles hold their wings flat.

Hundreds of breeding pairs of bald eagles now reside in Maryland as year-round residents. By the early 2000s, the state had recovered to several hundred active nests, a dramatic increase from the 1970s low of about 40 pairs. These resident birds hold territories along the Chesapeake Bay and its rivers, maintain large stick nests year after year, and raise young in spring and early summer. The recovery program worked, and Maryland is now a national stronghold for the species.

Yes, resident bald eagles stay in Maryland throughout winter. The core breeding population lives along the Chesapeake Bay and its rivers in every season. On top of these residents, migrant eagles arrive from the north in late fall and early winter, congregating wherever open water keeps fish reachable. Winter water conditions concentrate the entire population at a few hotspots like Conowingo Dam, where the turbines keep water open and create feeding opportunities, and Blackwater Refuge, where the larger impoundments support massive gatherings.

Adult bald eagles are large raptors. They measure from 28 to 40 inches from beak to tail, with females on the larger end of the range. Their wingspan typically ranges from 6 to 7 and a half feet across. A perched bald eagle standing on a rock or tree snag is unmistakable, towering above any bird you might see. When they fly, their wings are broad and powerful, and they often soar high with a flat wing posture that is distinctive compared to smaller hawks or eagles of other regions.

Apart from the rare golden eagle sightings in winter, no other eagle species are regular visitors to Maryland. Some birders have reported vagrant sightings of steller's sea eagles or other western species blown off course, but these are exceptionally rare events. Your realistic expectation for Maryland is bald eagles as residents and migrants, with a golden eagle as an exciting winter bonus if you are lucky. Focus your search on these two species.
