HABITAT DESCRIPTION:
NATURE SERVE GLOBAL HABITAT COMMENTS:

Deciduous forest, open woodland, second growth, scrub, brushy areas and chaparral (Tropical to lower Temperate zones) (AOU 1983). Also open pinyon-juniper woodland. Wide range of brushy habitats in winter. Nests especially where tracts of brush, scrub, or chaparral are intermixed with taller vegetation (e.g., forest edge, riparian corridors). Often breeds near water. Nest is built in branch or fork of tree or shrub, usually 1-25 m above ground, by both adults (Harrison 1978).

 
MODELING DESCRIPTION:
Occupied Landcover Map Units:
Code NameDescription NC Natural Heritage Program Equivalent
75 Tidal Swamp Forest Swamp tupelo dominated forest with or without black tupelo and/or cypress trees. Restricted to the tidal zones in the coastal plain. May have inclusions of coastal red cedar woodlands. Tidal cypress - gum swamp
17 Maritime Forests and Hammocks Maritime forests and woodlands dominated by live or sand laurel oak. Estuarine Fringe forests dominated by loblolly pine. Coastal Fringe Evergreen Forest, Maritime Deciduous Forest, Maritime Deciduous Forest
173 Coastal Plain Riverbank Shrubs Shrub dominated riverbanks, commonly dominated by willows and/or alders. Sand and Mud Bar
50 Coastal Plain Mixed Bottomland Forests Includes forests dominated by a variety of hardwood species, including sweetgum, cottonwood, red maple. Coastal Plain Bottomland Hardwood (in part), Coastal Plain Levee Forest
49 Coastal Plain Oak Bottomland Forest Bottomland forests dominated by deciduous oak alliances. Oaks represented can include swamp chestnut, cherrybark, willow, and/or overcup oak. Inclusions of loblolly pine temporarily flooded forests occur in patches. Hydrology is temporarily to seasonally flooded. Coastal Plain Bottomland Hardwoods (in part) blackwater subtype, brownwater subtype
158 Coastal Plain Nonriverine Wet Flat Forests Loblolly pine - Atlantic white-cedar - red maple - swamp tupelo saturated forests as well as forests dominated by loblolly, sweetgum, and red maple in non-riverine flats. Non-riverine Wet Hardwood Forest
15 Seepage and Streamhead Swamps Includes extensive peat flats in the coastal plain, dominated by swamp tupelo, maples, and Atlantic white cedar alliances. In the sandhills includes streamhead pond pine and bay forests alliances. Saturated hydrology. Bay Forest, Small Depression Pocosin, Streamhead Atlantic White Cedar Forest, Streamhead Pocosins
30 Cypress-Gum Floodplain Forests Swamps dominated by black or swamp tupelo with or without Taxodium. Seasonally to semi-permanently flooded hydrology. Cypress-Gum Swamps
78 Pond-Cypress - Gum Swamps, Savannas and Lakeshores Cypress dominated swamps and lakeshores. Can include bays dominated by pond cypress or shorelines of coastal plain lakes with a narrow band of cypress. Non-riverine Swamp Forest, Natural Lakeshores (in part)
385 Oak Bottomland Forest and Swamp Forest The swamp chestnut oak, cherrybark oak, shumard oak and sweetgum alliance is one representative. Other alliances are dominated by water, willow, and overcup oaks. Swamp forests can be dominated by sweetgum, red maple, and black gum being dominant. Loblolly can occur in combination with sweetgum and red maple, or with tulip poplar. Includes saturated and semi- to permanently flooded forests in the mountains. Piedmont/Mountain Bottomland Forest, Piedmont/Mountain Swamp Forest
63 Coastal Plain Mesic Hardwood Forests Beech dominated forests with white oak and northern red oak as possible co-dominants. Dry-mesic to mesic forests on slopes and small stream bottoms in the coastal plain. Mesic Mixed Hardwood Forest, Basic Mesic Forests
267 Riverbank Shrublands Riverside shrubs with temporarily flooded hydrologies. Found in the both the Mountains and Piedmont. Containing dominants such as smooth alder and a Carolina or black willows. Sand and Mud Bar

230 Piedmont Mesic Forest American Beech - Red Oak - White Oak Forests. Mesic Mixed Hardwood
384 Piedmont/Mountain Mixed Bottomland Hardwood Forests Includes temporarily to seasonally forests dominated by hardwood species. Hardwoods include sweetgum, red maple, sycamore which co-occur in a mosaic of bottomland and levee positions. Includes alluvial hardwood forests in the mountains. Hemlock and white pine may occur as inclusions, but are generally mapped separately. Piedmont/Mountain Alluvial Forest, Piedmont/Mountain Levee Forest
383 Piedmont Mixed Successional Forest Generally loblolly mixed with successional hardwoods. Sweetgum, tulip poplar and red maple are common co-dominants in these successional forests. No equivalent
