Jamaican Owl
Asio grammicus
A somewhat large nocturnal inhabitant of wooded areas including gardens and parks; roosts in tree cavities or dense foliage during the day. The Barn Owl is of similar size, but it is much paler and lacks the Jamaican Owl’s prominent ear tufts. Vocalizations include a low, gruff “wa-waaa-o” and a crescendo/decrescendo “whoa.”
识别特征
The Jamaican owl is 27 to 33 cm (11 to 13 in) long; one specimen of unstated sex weighed 335 g (11.8 oz). This medium-sized owl has long ear tufts, dark brown eyes, and a rufous facial disk rimmed in black-flecked white. The adult's upperparts are rufous with fine dark brown vermiculation. The tail is also rufous, with dark brown bars. The breast and belly are rufous with narrow dark brown streaks. The juvenile's back is light grayish brown and the rest of its plumage is light cinnamon-buff.
分类信息
The Jamaican owl was previously considered the only member of the genus Pseudoscops, but phylogenetic analysis has reclassified it within Asio. It is monotypic.

行为
The Jamaican owl is nocturnal and eats mainly large insects. Its diet also includes spiders, amphibians, lizards, and rodents. There is one record of its taking a bird, a Greater Antillean grackle (Quiscalus niger).<p>The Jamaican owl's breeding phenology is poorly known. Nesting has been reported between March and October and egg-laying between December and June. It lays a clutch of two eggs in a tree cavity or a concealed tree-fork.<p>Adult Jamaican owls make a "[h]igh, quivering hoot and guttural growl".

Whooping Motmot
Momotus subrufescens
Large motmot of lowland forest and edges from eastern Panama to northwestern South America. Green above and warm rufous below, with a black mask bordered by a dazzling cerulean crown. The crown is not solidly blue, but instead has a circular black patch in the middle as if it’s wearing a yarmulke. Like most other motmots, has conspicuous tail racquets. In typical motmot fashion, perches quietly for long periods of time anywhere from the understory to the canopy, occasionally flicking its tail side to side. Gives a low single “whoop” call.
Masked Lark
Spizocorys personata
An unusual, distinctive, relatively colorful medium-sized lark. Note the black "mask," the pale bill, and the rufous-washed belly. The sides of the tail are pale buff, which can be obvious in flight. Found very locally in dry country, in short grassland and on lava fields. The song is a simple whistled phrase that can be given on the ground or in a flight display.
Spot-billed Ground-Tyrant
Muscisaxicola maculirostris
Fairly small and drab terrestrial flycatcher of open rocky and stony slopes and valleys, and adjacent agricultural terraces in the Andes; also locally in desert lowlands mainly in winter. Virtual absence of field marks is a field mark: plumage unrelieved by strong contrast or color. Best told from other ground-tyrants by small size, faint dusky breast streaking, relatively short wings, and much stronger song. Also note yellow base of bill that is visible at close range.
