Porphyrio martinicus
| Conservation status | Still widespread in appropriate habitat, but undoubtedly has decreased with draining of swamps, and still vulnerable to loss of more wetlands. |
|---|---|
| Family | Rails, Gallinules, Coots |
| Habitat | Fresh swamps, marshes, ponds. In North America usually in extensive wetlands with still or slow-moving shallow water, lots of dense marsh cover and floating vegetation. In tropics may be found also on smaller ponds, ditches. During migration, individuals may stop over in odd habitats, even in cities. |
Forages while walking on land, while climbing through marsh vegetation or waterside shrubs or trees, or while swimming.
6-8, sometimes 5-10. Buff with brown spots. Incubation is by both sexes, 22-25 days. Young: May leave nest shortly after hatching, move to 2nd nest. In feeding young, parents are often assisted by other birds (as many as 8); these "helpers" evidently all are previous offspring of breeding pair, and juveniles less than 10 weeks old may help feed newly hatched chicks. Young are capable of flight at roughly 9 weeks.

Omnivorous. Eats a wide variety of plant and animal matter, including seeds, fruits, and leaves of aquatic and terrestrial plants, also insects, frogs, snails, spiders, worms, fish. At times, eats the eggs and young of other birds.
Breeding behavior has been studied mostly in Costa Rica. May breed at any season in tropics, only in spring and summer in North America. Nest site is in dense marsh growth, over water that is often several feet deep. Nest (built by both sexes) is platform of cattails, grasses, sedges, firmly anchored to standing marsh vegetation, at water level or 1-3' above it. Often build extra nests.
Olimpia Zagnoli's bird has plenty of style—both on and off the page.
Two-thirds of North American bird species are at risk of extinction from climate change. Urge Congress to act now.
