识别特征
The buff-rumped thornbill (Acanthiza reguloides) is a small passerine bird species belonging to the genus Acanthiza, most of which are endemic to Australia. Measuring 8–10 cm in length, this unassuming thornbill is characterised by its plain greenish brown upperparts and very pale-yellow underparts, with a distinctive buff coloured rump. The tail has a broad, blackish band with a paler tip. Adults possess white irises, whilst juveniles have dark eyes. The buff-rumped thornbill is one of 14 species within the genus Acanthiza genus, which are recognisable by their thin, pointed bill. Species are unique in their plumage and distribution. Despite their shared name, the genus is not related to hummingbirds.
分类信息
Early classifications of the genus Acanthiza based on plumage and morphology recognised one to three genera with a varying number of species in each. However, recent classifications have recognised one genus containing five species groups or four groups excluding the New Guinean murina.<p>The taxonomy of the Acanthiza reguloides has undergone significant change and debate since its early classification. Despite marked differences between A. reguloides and A. squamata, they have been combined as a single species since 1926. Four subspecies of Acanthiza reguloides are recognised. These are:

Ferruginous Pygmy-Owl
Glaucidium brasilianum
Widespread and generally common little owl of tropical lowlands, often seen and heard during the daytime. Favors open tropical woodland and edge, second growth areas with trees (including towns, even cities with wooded parks), tropical pine savannas. Persistent whistles and mobbing bands of small birds often draw attention to pygmy-owls, which can be perched up on open snags or buried deep in cover. Color varies from rusty to grayish overall, but all color types have fine whitish streaks on crown (not spots) and numerous, narrow dark tail bars.
White-winged Parakeet
Brotogeris versicolurus
Small bright green parakeet, with striking white-and-yellow pattern on wings, visible in flight. Long, pointed tail. Bill and legs dull pinkish. White eyering. Native to South America; established populations exist in southern Florida and southern California. Usually found in small flocks in wooded or suburban areas. Listen for harsh, high-pitched calls.
