Pelzeln's Tody-tyrant Hemitriccus inornatus



Justification

Justification of Red List category
This species has a large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence under 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). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (under 10,000 mature individuals with a continuing decline estimated to be over 10% in ten years or three generations, or with a specified population structure). 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 (over 30% decline over ten years or three generations). For these reasons the species is evaluated as Least Concern.

Population justification
The global population size has not been quantified, but the species is described as locally common to fairly common (del Hoyo et al. 2004). This species is considered to have a medium dependency on forest habitat, and tree cover is estimated to have declined by 1.7% within its mapped range over the past 10 years (Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein). Therefore, as a precautionary measure, it is tentatively suspected that this loss of cover may have led to a decline of between 1-19% in the species' population size over the same time frame.

Distribution and population

This species was rediscovered in 1992 (161 years after the collection of the type-specimen) in campina forest on the east bank of the rio Negro, c.45 km north of Manaus, Brazil, extending its range by c.1,000 km east-south-east of the rio Içana type-locality (Whittaker 1995). It has subsequently been found in several other areas further up the rio Negro on two right-bank tributaries, the rio Apuaú and rio Cuieras, c.80 km north-west and 60 km west of the 1992 records (Whittaker 1995), and appears to be relatively common in white-sand and igapó forests on the east bank of the rio Negro (M. Cohn-Haft in litt. 1999).
