Red-and-green Macaw
Ara chloropterus
Enormous parrot with a long pointed tail, a red head and body with mostly blue wings and green wing coverts. It has a white face with distinct red stripes. Only possible confusion species is Scarlet Macaw, which has yellow (not green) wing coverts and lacks red stripes on the face. Found in lowland rainforests from eastern Panama to Paraguay. Usually found in pairs, flying over the forest and perching in the canopy. Can gather in small groups, especially at fruiting trees or clay licks. Nests in cavities. Listen for raucous calls, typical of large macaws.
识别特征
The green-winged macaw can be readily distinguished from the scarlet macaw. While the breast of both birds are bright red, the upper-wing covert feathers of the green-winged macaw is mostly green (as opposed to mostly yellow, or a strong mix of yellow and green in the scarlet macaw). In addition, the green-winged macaw has characteristic red lines around the eyes formed by rows of tiny feathers on the otherwise bare white skin patch; this is one of the biggest differences from a scarlet macaw to the casual viewer. Iridescent teal feathers are surrounded by red on the tail. If seen together, the green-winged macaw is clearly larger than the scarlet macaw as well.<p>In terms of length, this species is second only in size to the hyacinth macaw, the largest of the macaws. The red-and-green macaw attains a total body length of 90 to 95 cm (35 to 37 in) in adults. Twelve adults were found to average 1,214 g (2.676 lb). A weight range of between 1,050 and 1,708 g (2.315 and 3.765 lb) has been reported. While its weight range is broadly similar to that of the hyacinth, the average weight of the red-and-green macaw is slightly surpassed by both the hyacinth and great green macaws, and amongst all living parrots additionally by the kākāpō.

Flavescent Warbler
Myiothlypis flaveola
Yellowish warbler found in deciduous dry forests and gallery forests where it forages hyperactively on the ground. Olive-green above and yellow below with orange legs. Note the conspicuous yellow eyebrow. The song is loud and melodious “titzi teetee teetee chiiw chiiw chiiw."
Spotted Owl
Strix occidentalis
Medium-sized owl typically found in mountainous regions with mixed conifers and oaks. Overall brown with bold white spots on belly and back. Black eyes, unlike most other owls; main confusion species is Barred Owl. Spotted is well-named, with much more obvious spots on chest and belly than Barred Owl, and lacks distinct vertical stripes. Also note voice: one hoot, followed by a pair of hoots, followed by a final single hoot. Two separate populations: birds along the Pacific coast and the Sierra Nevada average darker, richer brown than birds further south and inland.
Rusty-throated Parrotbill
Suthora przewalskii
A distinctive mid-sized parrotbill with a highly restricted range; limited to a small part of central China where it inhabits mid- to high-altitude montane scrub and open forests with dense low cover, particularly bamboo stands. Dull brown with a gray head, long black eyebrow, and a dark rusty-red face and throat. Moves in small flocks and vocalizes frequently, giving jumbled high-pitched squeaks and rattly trills.
