Taxonomy and systematics

The eared poorwill has sometimes been placed in genus ''Otophanes''. Two subspecies, the nominate ''Nyctiphrynus mcleodii mcleodii'' and ''N. m. rayi'' are recognized by most authorities. However, some authors contend that the latter is invalid.Clements, J. F., T. S. Schulenberg, M. J. Iliff, S. M. Billerman, T. A. Fredericks, J. A. Gerbracht, D. Lepage, B. L. Sullivan, and C. L.

Description

The eared poorwill is long. Males weigh and females . The nominate subspecies' upperparts are grayish with black and white spots on the wings. A white band that is wider on the throat encircles the neck. They have crown feathers that project as "ear tufts". The breast is grayish and the belly buff with white spots. The tail feathers except the central pair have white tips. There is also a rufous morph that has an overall cinnamon to reddish brown color. ''N. m. rayi'' has darker and grayer underparts and the white spots on the wings are smaller.

Behavior

Feeding

The eared poorwill forages for insects by sallying from trees or the ground. Beetles and moths appear to form the bulk of its diet.

Breeding

The eared poorwill apparently breeds between April and June. The clutch of two eggs is laid directly on the ground and both sexes incubate them.

Vocalization

The male eared poorwill's song is "a loud, abrupt 'peeyo' or 'peejo' that ends emphatically", and is given at night from a perch or the ground. It also makes "a descending, wavering 'teu-uu-uu'." Calls include "gwik", "wuik", and "chuck" notes.

Status

The IUCN originally assessed the eared poorwill as Near Threatened but since 2004 has rated it as being of Least Concern. It has a large range and population, though the latter is though to be decreasing. No immediate threats have been identified.
