Overview

Distribution

Geographic Range

Laterallus ruber is found in the northern parts of South America and into the southern areas of North America. The highest densities found of the ruddy crake are in Columbia and Central America. This species favors the wetlands and wet forests throughout these areas.

Physical Description

Morphology

Physical Description

Laterallus ruber superficially resembles other rails. This species has the characteristic short conical bill. The legs are long with wide spreading feet to move around in wet areas. The body shape resembles a water drop when the neck is extended. The feathers on the head are dull black. The rufous wings and the back have a reddish brown coloring mingled with brown and black. The male has a rusty red colored breast similar to the color of a ruddy duck. The female is only slightly more drab than the male. The tail is very short and stubby. A rusty colored stripe envelopes the dark eyes of the crake.

Trophic Strategy

Food Habits

Laterallus ruber feed on the invertebrates and plants they can find living at the surface or just beneath the surface of the water. This species will also feed from the mud and decaying plants in wetlands and in pools formed in large tree crevices. They mainly prey on water snails and insects such as water beetles, mayflies and mosquitoes, as well as their larvae. Water plants and grass may also be eaten but this is unconfirmed.

Life History and Behavior

Reproduction

Reproduction

Information on reproduction is unavailable on Laterallus ruber. This information is general to crakes.

Crakes generally lay 6-12 eggs in a nest made among tall aquatic plants at the waters edge. Both male and female brood them in turn for up to 3 weeks. As incubation starts before all the eggs are laid, the chicks emerge at intervals over a period of several days. They can leave the nest shortly after hatching. After the eggs have hatched, the male cares for them while his mate incubates the younger eggs. After all the eggs have hatched, both parents guard the chicks, feeding them until they are a week old. Sometimes the chicks split into two parties, each under the charge of one parent.

Justification
This species has a very large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend is not known, but the population is not believed to be decreasing sufficiently rapidly to approach the thresholds under the population trend criterion (>30% decline over ten years or three generations). The population size may be moderately small to large, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.

Conservation Status

The largest concern for this species is the one common to most tropical birds. Deforestation and habitat destruction have lowered the populations of the ruddy crake. These birds have benefited from the parks and land preserved by governments and concerned groups.

US Federal List: no special status

CITES: no special status

Population
Partners in Flight estimated the population to number <50,000 individuals (A. Panjabi in litt. 2008), which is placed in the band 20,000-49,999 individuals here.

Relevance to Humans and Ecosystems

Benefits

Economic Importance for Humans: Positive

The ruddy crake has no major economic value. Money from bird watchers and ecotourists can be accounted for but this species is not of major interest since other tropical birds are of greater interest.
