Madagascar Wood-rail Mentocrex kioloides
BirdLife is updating this factsheet for the 2016 Red List
Please email us with any relevant information

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). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size may be small, 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.

Taxonomic note
Mentocrex kioloides (del Hoyo and Collar 2014) was previously placed in the genus Canirallus.

Canirallus kioloides (Pucheran, 1845)

Population justification
The population is estimated to number 1,000-2,000 individuals, roughly equating to 670-1,300 mature individuals.

Trend justification
The population is suspected to be in decline owing to ongoing habitat destruction (del Hoyo et al. 1996).

Behaviour This species is a sedentary endemic of Madagascar (Taylor and van Perlo 1998). It breeds May-June, or November (del Hoyo et al. 1996), and normally forages in pairs (del Hoyo et al. 1996), or less frequently alone (Langrand 1990). Very little is known about this species social organisation or aggregatory behaviour (Langrand 1990, del Hoyo et al. 1996, Taylor and van Perlo 1998). Habitat The species shows a preference for forest habitats characterised by open understoreys and substrates of leaf-litter (Taylor and van Perlo 1998). It frequents water courses and reedy or papyrus-grown edges of ponds and marshes within primary and adjoining secondary rainforest with sparse herbaceous ground-cover (del Hoyo et al. 1996). It has also recently been observed in dry deciduous forest established on a karst subtratum (Langrand 1990). Diet Its diet is little known (Langrand 1990), but foods such as insects, amphibians and seeds have been recorded (del Hoyo et al. 1996). Breeding site The nest is a bowl of grass and leaves placed in a bush or a tangle of creepers (lianas) 2-3 m above the ground (del Hoyo et al. 1996).

The species is threatened by forest destruction from slash-and-burn agricultural practices, timber exploitation for firewood and clearance for rice and coffee plantations (del Hoyo et al. 1996, Taylor and van Perlo 1998).
