Plain Nightjar

Caprimulgus inornatus

A medium-sized, unusually plain nightjar. Overall coloration varies from rufous to brown to gray. Both sexes have a small pale mark in the outer wing, and males have a mostly white outer tail. Breeds mainly in arid savanna, but occurs in a wide variety of open habitats as a migrant and wintering bird. Similar in appearance to several other nightjars, but identified by the combination of overall plainness, lack of white on the throat, and vocalizations. The call is a mechanical trill, higher-pitched than that of Sombre Nightjar, but lower-pitched than that of Long-tailed Nightjar.

保护状况

This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence &lt;20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend appears to be stable, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (&gt;30% decline over ten years or three generations). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (&lt;10,000 mature individuals with a continuing decline estimated to be &gt;10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.

Rote Myzomela

Rote Myzomela

Myzomela irianawidodoae

A small honeyeater with a downcurved bill. Males blackish with a vivid red hood and rump and a paler belly. Females are brown with a paler belly and a noticeable red wash to the throat, forehead, and cheeks. Found singly or in pairs in lowland woodland, forest edge, and gardens, favoring the upper parts of trees. Unmistakable, as there are no other myzomelas in its limited range on Rote island. Vocalizations include a fast-paced sequence of staccato, metallic notes: “zip-zip-zip-zip-zip-zip…”.

Northern Carmine Bee-eater

Northern Carmine Bee-eater

Merops nubicus

Large and gorgeous bee-eater with a mostly carmine body, and blue-green head and belly. The central tail feathers are elongated. In flight, reveals a blue-green rump, and rosy underwings with black trailing edge. Found in a variety of savanna habitats. Usually in flocks, and breeds colonially in riverbanks. Often perches on the backs of mammals and large birds, catching the insects that they disturb. The call is low-pitched and raspy, less musical than most bee-eaters. Similar to Southern Carmine Bee-eater, but there is virtually no overlap in range, and easily separated by the blue-green rather than carmine throat.

Abert's Towhee

Abert's Towhee

Melozone aberti

Large, plain, long-tailed sparrow. Drab grayish-brown overall, with dark mask like a Northern Cardinal. Also note pinkish bill and orange undertail coverts. Inhabits riparian corridors, especially in dense brush. Mainly occurs in the Sonoran Desert of Arizona, barely extending into surrounding states and northern Mexico. Rather secretive as it forages on the ground for seeds and insects. Visits feeders.
