Collared Falconet (Microhierax caerulescens)


French: Fauconnet à collier German: Rotkehlfälkchen Spanish: Falconete acollarado

Falco caerulescens


, 1758,

Asia = Bengal


Possibly forms a species-group with M. fringillarius, which is sometimes treated as race of present species. Races differ little, and burmanicus perhaps not worthy of recognition. Two subspecies normally recognized.

  • M. c. caerulescens (Linnaeus, 1758) – E Himalayas from Uttarakhand and Nepal to NE India (N Assam; NE Odisha).
  • M. c. burmanicus Swann, 1920 – Myanmar E to C & S Indochina.
