Ecology
- Habitat
- Tidal ponds, mangrove swamps and other coastal areas with salt or brackish
(mixture of salt and fresh water) water. Less often in inland pools, marshes,
and other open areas. Nests in wetlands and on coastal islands, usually
on low trees, thick bushes, mangroves or reeds, occasionally on ground.
-
- Niche
- Omnivorous; eats small fish, crustaceans and shrimps; water beetles
and other insects, mollusk, slugs also some plant materlal, (fibers and
roots of sedges). Forages alone or in small flocks. Colonial nesters. Moves
bill side ways in long arches through water to eat. Sometimes immerses
entire head and part of neck. Generally sedentary throughout most range,
however migratory in north.
Life History
Nesting season depending where the bird is located: Florida birds lay
eggs in Nov. Texas birds lay eggs in Apr. Costa Rica birds breed from Oct-Dec.
depending on year. Nest is a platform of sticks and twigs lined with grass
and other soft vegetation. 2-3 egcs; incubate for 22 days, Chicks fledge
at 6 wks, mature at 3 yrs. or more.
Special Adaptations
- Beak is spoon shaped to help sift water and food through it.
- Long legs facilitate wading.
- Feed by sense of touch. This happens due to a sensitive touch receptors
under the horny covering of the bill. This species wades in the water with
its mouth open to snatch anything that touches its beak. This allows the
bird to feed in turbid water, muddy pools, dense under-water vegetation
or at night.
