Description
The forest owlet is small (23 cm) and stocky. It is a typical owlet with a rather unspotted crown and heavily banded wings and tail. They have a relatively large skull and beak. Unlike the spotted owlet, the forest owlet has the fewer and fainter spots on the crown and back. The upperparts are dark grey-brown. The upper breast is almost solid brown and the sides are barred with a white central wedge in the lower breast that is sometimes unmarked, especially in males. The primaries are darker and distinct. The wings and tail are banded with white trailing edges. A dark carpal patch on the underwing is visible in flight. The facial disc is pale and the eyes are yellow.[7]
Distribution and habitat
The forest owlet was recorded in central India, and until 1997 was known from just seven specimens in museums collected in northern
The forest owlet was observed in Odisha,
A survey in 2011 in non-protected areas of Maharashtra and Madhya Pradesh confirmed the presence of the species at two locations. In Maharashtra, a pair was observed (out of 7 pairs in 2004) in Toranmal Reserve Forest. In Madhya Pradesh, six individuals were observed in Khaknar.[12] In Maharashtra, it was also reported to inhabit the forest ranges of Taloda and Khaknaar.[13]All these places in central India harbour dense to open
In Gujarat, the forest owlet occurs in Purna Wildlife Sanctuary.[18]
Behaviour and ecology
The forest owlet typically hunts from perches where it sits still and waits for prey. When perched, it flicks its tail from side to side rapidly and more excitedly when it chases prey.
A study conducted in the forests of Madhya Pradesh revealed that the forest owlet is a generalist predator that consumes a variety of small mammals.[20]
The peak courtship season is in January and February during which time they are very responsive to call playback with a mixture of song and territorial calls.[14]
The forest owlet appears to be strongly diurnal, although not very active after 10 in the morning; it often hunts during daytime.[8] On cold winter mornings, it basks on top of tall trees.[19]
Filial cannibalism by males has been observed.[21]
Vocalization
They make several different calls, which include a hissing call of short duration. The song calls are short and mellow unlike those of most owls. They are usually disyllabic, "oh-owow" but sound monosyllabic and each note ascends and descends rapidly. The territorial calls have been transcribed as "kwaak … kk, kwaa..kk". A contact call of "kee yah, kee…yah" is given when the male brings food to the female at nest. The alarm call is a "chirrur… chirrur, chirr…chirr", while begging "kee…k, kee…k" calls are made when young or females seek food.[8]
