Javan Scops Owl

The average weight of this bird species is 75-90 grams with a body length of 160-180 mm. It has a small tail (63-69 mm) but large wings (135-149 mm) to accommodate its lengthy gliding distance. O. angelinae has a light rusty-brown facial disc and prominent white brows that extend into ear-tufts. Their hooked bill is 19.5-21.5 mm long and varies in colour from dark straw-yellow to light greyish-yellow. The upper part of their body is brown or rufous-brown, generally, with a rusty-buff hindneck-collar, whitish scapular stripe and remiges barred. Voice: While most scops owls usually make themselves known by their persistent vocalizations, the Javan scops owl is relatively quiet. The bird's alarm calls are repeated explosive "poo-poo" with a 0.5-second delay and a pitch decrease between the two notes. This call will be repeated multiple times and often has a trembling quality. The contact call of these birds is a hissing "tch-tschschsch".
