HABITAT DESCRIPTION: |
|
Absent on the barrier islands (Fussell and Lyons 1990); present throughout the rest of the state (Potter et al. 1980). Bluebirds forage in short sparse vegetation (Nicholson 1997), and nest in cavities located in fairly isolated trees (Alsop 1991). These requirements can be found in a variety of semi-open habitats with scattered trees, such as farms, roadsides,
burned areas, forest clearings, open pine woods, suburbs (Kaufman 1996), swamps (Harrison 1975), lawns, and golf courses (Nicholson 1997). Requires a nesting cavity located away from other overhanging trees (Alsop 1991). Cavities may include old woodpecker holes, birdhouses (Harrison 1975), mailboxes, or holes in fence posts (Potter et al.
1980). NATURE SERVE GLOBAL HABITAT COMMENTS: Forest edge, open woodland, and partly open situations with scattered trees, from coniferous or deciduous forest to riparian woodland but most frequently in pine-oak association, also pine woodland or savanna in tropics. Nests in natural cavity, old woodpecker hole, bird box, or similar site,
1-6 m above ground. Nesting holes often are usurped by starlings and house sparrows.
