This species qualifies as Endangered because it has a very small population; suitable habitat is declining through clearance for agriculture and introduced predators are also reducing numbers.

Geographic Range [top]

Range Description:Melanospiza richardsoni is endemic to St Lucia in the Lesser Antilles, where it is most numerous in the mountains (Bond 1979, Keith 1997). Surveys in 1987 failed to find any large populations and noted that much apparently suitable habitat was unoccupied (Keith 1997), although due to its broad habitat tolerance its range is probably not severely fragmented (H. Temple in litt. 2007).

Countries occurrence:

Population [top]

Population:The population is estimated to number 250-999 mature individuals based on an assessment of known records, descriptions of abundance and range size. This is consistent with recorded population density estimates for congeners or close relatives with a similar body size, and the fact that only a proportion of the estimated Extent of Occurrence is likely to be occupied. This estimate is equivalent to 375-1,499 individuals in total, rounded here to 350-1,500 individuals.

Trend Justification:  There are no new data on population trends, but the species is suspected to be in a slow decline owing to habitat degradation.
Current Population Trend:Decreasing
Additional data:
Number of mature individuals:250-999Continuing decline of mature individuals:Yes
Extreme fluctuations:NoPopulation severely fragmented:No
No. of subpopulations:1Continuing decline in subpopulations:Unknown
Extreme fluctuations in subpopulations:NoAll individuals in one subpopulation:Yes
No. of individuals in largest subpopulation:100

Habitat and Ecology [top]

Habitat and Ecology:It exhibits considerable ecological flexibility, inhabiting rainforest, forest edge, secondary vegetation, plantations, shrubbery, semi-arid scrub and woodland, up to 800 m (Bond 1979, Trail and Baptista 1989, Keith 1997). However, it has a preference for dense undergrowth, which is naturally found in ravines within moist montane forest (Keith 1997). Birds feed primarily on the ground on seeds, fruit and insects (Keith 1997). Nesting has been recorded in April-June.

Continuing decline in area, extent and/or quality of habitat:Yes
Generation Length (years):3.8
Movement patterns:Not a Migrant

Threats [top]

Major Threat(s): The clearing of undergrowth, particularly in timber plantations, renders areas completely unsuitable and is probably the major threat (Keith 1997). Introduced mongooses and rats may also predate eggs, nestlings and adults (Keith 1997).

Conservation Actions [top]

Conservation Actions: Conservation Actions Underway
It occurs in a number of forest reserves, such as La Sorcière and Edmond (Raffaele et al. 1998).

Conservation Actions Proposed
Assess the species's current distribution and population, and use the results to design a conservation strategy. Curtail undergrowth clearing in plantations and other forested areas (Keith 1997).
