Mindanao Boobook Ninox spilocephala

A fairly small owl of lowland forest on Mindanao. Dark brown on the head and upperparts with speckles on the wing, a reddish-brown chest, a white belly with thick reddish-brown streaking, and yellowish eyes. Similar to Chocolate Boobook, but Mindanao is much smaller and lacks any white on the chest. Song is a short three-noted phrase “boo-woo! boo!” with the first and second notes slurred.
