Introduction

The White-throated Crake has occasionally been considered conspecific with the Rufous-sided Crake (Laterallus melanophaius), although most modern commentators have preferred to retain them as separate species, and indeed the present species might prove to be more closely related to Gray-breasted Crake (Laterallus exilis). The White-throated Crake occurs from southeast Honduras to Panama, thence south through western South America to western Ecuador. It overlaps geographically with only one other species of Laterallus, the Ruddy Crake (Laterallus ruber), which is easily separated from the present species by its dark-headed appearance and bright rufous underparts. The White-throated Crake is a generally fairly common but difficult-to-see resident of marshes, damp pastures, overgrown ditches and streamsides, as well as thickets and forest clearings. It has been recorded to at least 1600 m.

Field Identification

14–16 cm; male mean 50 g, female mean 45 g. Occasionally has remiges faintly mottled or barred with white. Sexes alike. Only sympatric Laterallus is L. ruber, which lacks barring on underparts. Differs from L. melanophaius in less extensive white on throat and only onto upper breast; undertail-coverts clearly barred. Immature similar to adult but duller; pale tips to head feathers; sides of head to sides of breast grey, flecked with cinnamon; belly dark brown, very narrowly barred whitish. Juvenile not described. Races separated on plumage: cinereiceps has grey face, cerdaleus has fairly uniform reddish brown head and throat.

Systematics History

Editor's Note: This article requires further editing work to merge existing content into the appropriate Subspecies sections. Please bear with us while this update takes place.

Sometimes considered conspecific with L. melanophaius, which replaces present species E of Andes; may, however, be closer to L. exilis. Three subspecies recognized.

Subspecies

SUBSPECIES

Laterallus albigularis cerdaleus Scientific name definitions

Distribution

N Colombia (Candoacute;rdoba to Santa Marta region and S in Magdalena Valley to Cundinamarca) and extreme NW Venezuela (1).


EBIRD GROUP (MONOTYPIC)

White-throated Crake (Gray-faced) Laterallus albigularis cinereiceps Scientific name definitions

Distribution

SE Honduras and Caribbean slope of Nicaragua S through Costa Rica to NW Panama (W Veraguas).

Distribution

Editor's Note: Additional distribution information for this taxon can be found in the 'Subspecies' article above. In the future we will develop a range-wide distribution article.

Habitat

Marshes, wet fields and damp grassy pastures, overgrown banks of ditches, canals, ponds and streams, and drying stream beds; also thickets and forest clearings. Does not require standing water; more associated with grass than with marshes in Colombia. Inhabits lowlands up to 1600 m.

Movement

Resident throughout range, but in wet season may wander to higher ground with low cover.

Diet and Foraging

Takes insects, spiders, seeds of grasses and sedges, and algae. Recorded feeding on fruits of Conostegia subcrustulata (Melastomataceae) (2). Although normally confined to dense vegetation, ventures into more open spots to feed at dawn and dusk or in dull, rainy weather.

Sounds and Vocal Behavior

Abrupt, explosive descending trill or churr, similar to that of L. ruber; alarm note a sharp “chip”.

Breeding

Breeds Costa Rica in wet season; Colombia, breeding condition Dec–Aug. Nest a ball, with a side entrance, of woven grass stems and leaves, placed up to 60 cm above ground or water in grass tussock or bush. Eggs 2–5; black downy chick has pale brownish white bill with black band anterior to nostril.

Not globally threatened (Least Concern). Very difficult to see and status unclear; considered common over much of its range in 1970s and 1980s, but in 1960s race albigularis was relatively uncommon except in some lowland regions. Recorded in extreme N Peru, near Tumbes, in 2014 (3).
