Notes on Mottled wood owl (Strix ocellata)

The Mottled wood owl (Strix ocellata) is a huge species  of owl (40 – 48cm) which is endemic to the Indian subcontinent.

They are found in gardens and thin deciduous forests adjacent to dry thorn forests or farmland. The best place to see them in Gujarat is Gir National Park. I have encounterd this species at GIR and Rajpipla Forest areas regularly. This being one of my favorite owls I never miss an opportunity to photograph them.

Mottled wood owl is a earless owl (without ear tufts) with a white facial disk with concentric black barring and splashes of rufous. As the name suggests, it is mottled on its crown and upperparts with with reddish-brown and black.. The sexes are alike. The chin is white which is clearly visible when they start calling. The eyelid is orange and the iris is dark brown. The tail is barred narrowly in brown and black. The concentric barring on the face and mottled crown separate it from the Brown Wood Owl ( Strix leptogrammica).

There are three subspecies recognized and there are no sharp demarcations in their distributions. Race S. o. grisescens intergrades with nominate S. o. ocellata in N India (Ref: HBW 5, p. 197)
