Justification of Red List category
This species has declined rapidly since the early 1980s, and the population and range are now small, fragmented and continuing to decline. It may decline more rapidly in the future owing to the westward spread of Pearly-eyed Thrasher Margarops fuscata and therefore deserves to be monitored closely. It consequently qualifies as Vulnerable.

Population size: 1500-7000 mature individuals

Population trend: Decreasing

Distribution size (breeding/resident): 8,300 km2
