Bank Swallow

Open sand of beaches, dunes and the hollows between them.

Tidal marshes of the Atlantic and Gulf coasts where the source does not say whether the water is fresh, brackish or salt. A stated salinity files the marsh under freshwater tidal marshes or salt and brackish marshes instead.

Shallow ponds in Coastal Plain depressions, such as limesinks and the ponds in some Carolina bays, that rise and fall with the seasons.

Wet ground taken over by weedy or introduced plants after disturbance, such as common reed, Chinese tallow or tamarisk stands; the upland counterpart is roadsides, fields and disturbed ground.

Forests on low ground beside rivers and streams that flood from time to time.

Marshes along tidal rivers where the water is fresh but rises and falls with the tide.

Wet, open, peaty mountain wetlands fed by seepage, often with sphagnum moss.

Still water and its edges: ponds, lakes, millponds and reservoirs.

Coastal marshes flooded by salty or brackish tides.

Salt and brackish open water of sounds, bays and estuaries, with the mud and sand flats and seagrass beds that tides cover and uncover; the vegetated marsh is salt and brackish marshes.

Forests and open woodlands on dry ridges and slopes, often oak or pine.

Open, thin-soil openings and rock on limestone, dolomite or other lime-rich rock, including cedar glades.

Treeless grassy or shrubby summits and ridges in the high mountains.

Steep, sun-baked slopes of loose shale with sparse oaks and Virginia pine and their own endemic wildflowers. Linked only where the source names shale barrens; calcareous shale stays with the limestone glades.
