Archived 2014 discussion: Balsas Screech-owl (Megascops seductus): downlist to Least Concern?

Balsas Screech-owl Megascops seductus has a moderately small range in west-central Mexico, where it is a fairly common resident. It is listed as Near Threatened on the IUCN Red List because it was thought to have a restricted range that approaches the threshold for listing as Vulnerable, however this species has been mapped by Natureserve/BirdLife International as having an estimated Extent of Occurrence (EOO) of 80,200 km2, hence it does not appear to approach the IUCN thresholds and appears to warrant downlisting to Least Concern.

Archived: How many subspecies have gone extinct in the Neotropics?

BirdLife International is currently working on a project to produce a synthesis of all bird taxa, at the species and subspecies level, that are known or thought to have gone extinct since 1500. This is the first time that subspecies extinctions have been systematically documented and analysed, and we hope that the results will provide new insights to support global efforts (including through the BirdLife Partnership) to conserve the world’s threatened birds. Subspecies extinctions are generally not well documented, and so we would greatly appreciate any information and updates (including on recent surveys or rediscoveries) to support this effort.

Blue-and-gold Tanager Bangsia arcaei is currently listed as Near Threatened under criteria A2c; A3c; A4c; B1a+b(i,ii,iii,iv,v) because, although its Extent of Occurrence (EOO) is less than 20,000 km2 and declines are suspected in its range owing to habitat clearance and degradation, and its population is suspected to be experiencing a moderately rapid decline owing to the same threats, the population, however, is not yet considered to be severely fragmented or restricted to a few locations. The latest population estimate for this species in Costa Rican Important Bird Areas of 2,500-3,900 mature individuals (Sánchez et al. 2009) suggests that the total population could number fewer than 10,000 mature individuals.

Military Macaw Ara militaris is listed as Vulnerable under criteria A2c,d; A3c,d; A4c,d on the basis that a population decline equivalent to 30-49% over 10 years is suspected in the past and projected in the future, owing to habitat loss and harvesting for the pet trade (Snyder et al. 2000). Recently it has been noted that the species appears to be rarely traded in Bolivia, where good numbers are protected in five national parks (B. Hennessey in litt.). This raises the question of whether the population is still in rapid decline.
