[4] The Tamaulipas pygmy owl is endemic to Mexico where it is only found in the mountains of northeastern Mexico, in the northern part of the state of Hidalgo and the southeastern part of the state of San Luis Potosí.

[4] This owl is partly diurnal and feeds on insects and small vertebrates such as lizards.

Little is known of its breeding habits but it generally chooses a hole in a tree previously used by a woodpecker.

A clutch of up to four white eggs is laid and the young are able to fly soon after they emerge from the nest.

The forests in which this owl lives are being logged and the bird's range is now thought to be smaller than it was in the past.
