Cyornis magnirostris


Taxonomy [top]

Kingdom Phylum Class Order Family

Scientific Name: Cyornis magnirostris
Species Authority: Blyth, 1849
Common Name(s):
English Large Blue-flycatcher
Taxonomic Notes: Cyornis banyumas (Sibley and Monroe 1990, 1993) has been split into C. banyumas and C. magnirostris following Renner et al. (2009) who point out parapatric (and possibly sympatric) breeding between C. banyumas whitei and C. magnirostris, strong migratory habit in magnirostris which is weak or absent in banyumas and a number of morphological differences between the two taxa.

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2012

This species has an extremely 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 trend appears to be stable, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size has not been quantified, 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). For these reasons the species is evaluated as Least Concern.
