Identification: Similar to Brown Boobook. Overall brown colouration with large, yellow eyes and small, white patch above bill. Field identification from Brown Boobook is tricky with this bird possessing more elongated, teardrop-shaped streaking compared to the rounder, more heart-shaped streaks of the local subspecies of the Brown Boobook. This bird also possesses proportionally longer wings than the resident species, however, this is hard to make out in the field.
Similar looking species: Brown Boobook
Habitat: While on migration will make use of any habitat with trees, including scrubland and other areas outside of the closed forests that characterise our central reserves.
Behaviour/Ecology: Long-distance migrant from eastern Asia. Vocalisations are highly distinct from local Brown Boobook, but calls rarely in its wintering grounds.
Local Status: Rare migrant
Conservation Status: Least Concern (BirdLife International 2016)
