Northern Boobook

Scientific Name: Ninox japonica
Malay Name: Pungguk Betemak Utara
Chinese Name: 北鹰鸮

Range:
Breeding Range: (OR) Russian Far East to Korea, Japan; Taiwan

Taxonomy:
Polytypic. Subspecies are: florensis, japonica, totogo.

Size: 30-31 cm

Identification:
Similar to Brown Hawk-owl. Overall brown colouration with large, yellow eyes and small, white patch above bill. Field identification from Brown Hawk-owl 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 Hawk-owl. 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 Hawk-Owl

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 Hawk-owl, but calls rarely in its wintering grounds. 

Local Status: Uncommon migrant

Conservation Status: Least Concern (BirdLife International 2016)

Location: Records from Tuas South, Pasir Ris Park, and Satay By The Bay but could conceivably occur in any place with trees.
