Archived 2011-2012 topics: Neblina Metaltail (Metallura odomae): request for information

Neblina Metaltail Metallura odomae is relatively common within three areas of southernmost Ecuador (including Podocarpus National Park), and on Cerro Chinguela, northern Peru (Piura), at 2,850-3,350 m. It occurs in elfin forest, forest edge and scrub where, despite its reasonable numerical abundance, it may be of conservation concern owing to its highly restricted distribution. However, Ridgely and Greenfield (2001) believe that “given its relative abundance in its very remote range – where habitat disturbance has, at least to date, been minimal or non-existant – we do not believe it merits listing as even a NT species”.

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.

This species is noted to be declining in Colombia and western Ecuador, owing to the clearance of subtropical forest, which has been severe and rapid on Andean slopes (Juniper and Parr 1998). Anecdotal evidence, based on the frequency of sightings, suggests that the species has declined in Piñas, southern Ecuador, over the past c.15-20 years (M. Sanchez per D. Díaz in litt. 2011). It is also said to have been extirpated from formerly occupied areas such as the Andean slopes of Cauca and Magdalena Valleys in Colombia, again owing to habitat loss (Juniper and Parr 1998).

Archived 2011-2012 topics: Hooded Grebe (Podiceps gallardoi): does it qualify as Critically Endangered?

The results of surveys conducted on more than 50 lakes and lagoons that could hold breeding populations, including the six key waterbodies that held c.40% of the total population in the 1980s, suggest that the rate of decline may have been more rapid than previously thought (Imberti and Casañas 2010). When mean counts from the 1980s are summed across these six main sites, a total of 1,832 adults are estimated to have been recorded; however, surveys at these same sites in 2009 yielded records of only 117 adults. Furthermore, an estimated total of c.580 nests were recorded at these six sites during the 1980s, with not one found during the surveys in 2009 (Imberti and Casañas 2010). The difference in the number of adults recorded suggests that a decline of c.94% has occurred at these sites over c.24 years. This equates to a decline of 90.5% over the past 21 years, assuming an exponential trend. Continue reading

Recent observations of the species in human-altered habitats such as eucalyptus plantations and young secondary forest (A. Lees in litt. 2011) suggest that it has a high tolerance of habitat degradation and disturbance. It has been suggested that the severe level of deforestation around Paragominas in the state of Pará has probably increased the area of suitable habitat for this species. No evidence was found during three months of fieldwork in this area to suggest it is a regular target for hunters (A. Lees in litt. 2011). It is proposed that the species be downlisted to Least Concern, as it is no longer believed to approach the thresholds for Vulnerable under any of the IUCN criteria.
