African Barred Owlet
Glaucidium capense
Chunky brownish owlet. Shows bars on the breast and spots on the belly. There is significant though subtle geographic variation. The back can be solidly chestnut or brown and barred, the back of the neck is barred, and the top of the head is either spotted or barred. Found in a variety of forest, from lowland rainforest to montane forest, as well as in thickets, and thick woodland. Often active and vocal during the day. Gives a yelping series of hoots, which are usually followed by emphatic, modulated, descending “ptrrrrr” notes. Similar to Pearl-spotted Owlet but has barring rather than spotting on the upperparts, and spots and bars rather than streaking on the underparts. Very similar to the rare Albertine Owlet, but in the area of overlap, has white rather than cream spotting on top of the head, a less richly-colored chestnut back, and a white rather than buff slash across the shoulder. Also reminiscent of Red-chested Owlet, but larger, with a barred chest, and lacks white spots on the tail.
识别特征
The African barred owlet is a small owlet that shows some geographic variation (see Taxonomy). The nominate subspecies is greyish brown above with fine buff bars and a narrow white eyebrow. The scapulars and greater wing coverts have white outer webs with dark brown tips and form a white stripe across the shoulder and the folded wing. The brown chest is finely barred with buff and the breast and flanks are white with brown spots. The underwing coverts, legs and vent are white, while the flight feathers and tail are brown barred with rufous. The bill and cere are dull greenish yellow and the eyes, legs and feet are yellow. Length is about 17 cm (6.7 in) and wingspan is about 40 cm (16 in).<p>The call of the African barred owlet is a series of single pitched purring notes.
分类信息
There are currently three subspecies recognised but many authorities recognise each of these as a separate species. Others in the complex like G. capense etchecopari (or Etchecopar's barred owl) are of uncertain status. The subspecies are:

行为
The African barred owlet is partly diurnal. Calling occurs mainly at dusk and dawn but also through the night on calm and clear nights. It is frequently observed on open perches scanning for prey, even during the day. It roosts within cover, often in a natural cavity in a tree. If they are detected by other birds during the day they will often be subjected to mobbing. The African barred owlet feeds on small mammals, birds, reptiles, frogs, insects, scorpions and caterpillars which are normally caught following a short flight from a perch.<p>Both sexes call to proclaim their territory, most frequently before breeding. The nest site is usually a tree cavity 3–6 m (9.8–19.7 ft) from the ground. Two or three eggs are laid from September to November. The young are fed by both parents but only in the dark, fledging after 30–33 days and becoming independent after 7–12 months.

Cardinal Lory
Chalcopsitta cardinalis
A thick-bodied, long-tailed parrot with entirely red plumage. The head appears slightly brighter than the body. Widespread in most habitats up to around 1200 meters of elevation. Unlikely to be misidentified due to its unique entirely red coloration. Most common call is a high-pitched rising “tsleet!”
St. Lucia Amazon
Amazona versicolor
A stout inhabitant of wet montane forests; sometimes ventures into orchards. This species often appears green with a bluish head, though a variable amount of red is present on the chest and belly. In overflight, a small red patch on each wing can be seen above and below. No other parrots occur within its range, and no parrot commonly kept in captivity resembles this species. Calls include a somewhat sharp “ka-chuck” and plaintive “ay-uh.”
David's Fulvetta
Alcippe davidi
Rather plain, social bird of hilly and montane forests. Brown with a gray head and bright white eyering. Very similar in appearance to Huet’s and Yunnan fulvettas, both of which have a prominent black brow stripe; this feature is either extremely faint or absent in David’s. Forms large flocks, often with other species, which move around in the middle levels of forests. Gives chattering call notes.
