Falco rufigularis


The Bat Falcon (Falco rufigularis) is a falcon that is a resident breeder in tropical Mexico, Central and South America and Trinidad.
It was long known as Falco albigularis; the name Falco fusco-coerulescens or Falco fuscocaerulescens, long used for the Aplomado Falcon
are now believed to refer to the present species .
Bat falcon adult males measure 24-29 cm (8-10 in.) in length with a wingspan of 56-58 cm (18-19 in.) females also range from 24-29 cm (8-10 in.)
in length but have a larger wingspan, which ranges between 65 and 67 cm (21-22 in.)
in length.
The head and upper parts of their body are black, with grayish edging to contour the feathers from their upper back to tail coverts.
Their throat and upper chest is white and tan extending to their neck.
They have a long black tail with many fine white or gray stripes, and buff tip.
The bat falcon has deep brown irises that may help camouflage while hunting at night.
They also have small hooked beaks that allow the bat falcon to easily tear its meat.
