Where did the banding of a swamp sparrow come from?

A Swamp Sparrow banded in eastern Massachusetts on October 4, 1937, was found in central Florida in January 1938, about 1,125 miles away. Before the development of tracking devices, banding returns such as this one helped clarify migration patterns for many bird species.

How many types of swamp sparrows are there?

Three subspecies of Swamp Sparrow are recognized. One, the “Coastal Plain” variant, prefers brackish rather than freshwater marshes and is only found in the Mid-Atlantic region, where it’s considered endangered due to ongoing habitat loss. Its Latin subspecies name, nigrescens, refers to its blackish nape.

Behavior. Swamp Sparrows are beautifully adapted to their wetland habitat, navigating agilely through dense cover whether in flight, running on the ground, or climbing through the reeds. Foraging birds walk along the water’s edge or just inside emergent vegetation, picking seeds and insects from the mud or water.

Where do swamp sparrows live?

Their clear, mellifluous trills resonate through wetlands from central Canada to the eastern United States, where Swamp Sparrows are fairly common but often hidden among aquatic plants.

What kind of bird is a swamp sparrow?

What causes song crystallization in Sparrows?

Artificially high testosterone levels in development cause early crystallization of song in zebra finches (Korsia and Bottjer, 1981), and reducing testosterone levels or blocking testosterone receptors delays song crystallization in sparrows (Marler et al., 1988).

Where do swamp sparrows forage?

Swamp Sparrows perch and forage in vegetation near the ground or water surface, where their rather long legs—longer than those of Song or Lincoln’s Sparrows—enable them to forage well. They typically forage near the water’s edge or in brushy patches within the habitat.

What happens to young male sparrows that are deaf?

Young male sparrows that are deafened or deprived of the opportunity to listen to any adult tutor (live or recorded) during song development develop songs that deviate substantially from a normal song yet still retain some characteristics of the species-typical song (Marler and Sherman, 1983 and 1985).

Where do swamp sparrows nest?

What is the difference between a swamp sparrow and Lincoln Sparrow?

Similar to the swamp sparrow, the Lincoln’s sparrow has a relatively small song repertoire with an average of 3.7 different song types per individual.
