Flammulated Flycatcher Deltarhynchus flammulatus

This species is classified as Least Concern. It has a very large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (extent of occurrence <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 may be moderately small to large, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). The population trend is suspected to be declining owing to habitat loss. Should new research suggest the population has declined by ≥30% in the past 11 years (one generation = 3.6 years) the species would warrant uplisting to Vulnerable and should research show the declines approach 30% it would warrant uplisting to Near Threatened.

Population justification
Partners in Flight estimated the population to number fewer than 50,000 individuals (A. Panjabi in litt. 2008), thus it is placed in the band 20,000-49,999 individuals here.

Trend justification
Local extirpations and severe on-going deforestation suggest that this species's population may be in decline (Rivera et al. 2011). Only 27% of tropical deciduous forest cover in 1990 in Mexico is left intact and <10% of the area covered with deciduous forest is protected (Trejo and Dirzo 2000, CONANP 2009). Further research is needed to quantify these suspected declines.
