Olive-crowned Flowerpecker
Dicaeum pectorale
A tiny bird of forest canopy from the lowlands to the mid-mountains in the west of New Guinea. Medium gray upperparts, pale gray underparts to whitish belly, and a whitish throat. Male has a bright red chest patch and a yellowish tinge to the head. Female has a broad pale stripe from the bill down to the center of the chest. Similar in size to a gerygone or Pygmy Longbill, but typical flowerpecker behaviour of flying vocally between the treetops. Voice, a buzzing “jig!” call, given regularly.
识别特征
The olive-crowned flowerpecker is a small bird, 9 cm (3.5 in) in length and weighing 7–7.8 g (0.25–0.28 oz). Nominate males have olive green upperparts and crown, yellowish rumps, grey-green underparts, yellowish-white central abdomen and undertail coverts, white throats, and a large scarlet patch on breast. Females are similar to males, but lack the scarlet throat patch and have yellower center of abdomen and undertail coverts. Juveniles are similar to females, but have more olive underparts.<p>Vocalisations include a short, insect-like buzzing note, a single, high upslurred note, and a drawn-out chew, repeated at intervals.
分类信息
The olive-crowned flowerpecker is one of 41 species in the genus Dicaeum. It is sometimes considered to be conspecific with the red-capped flowerpecker, Louisiade flowerpecker, or the Halmahera flowerpecker.<p>The olive-crowned flowerpecker was first described by Saloman Müller in 1843. The generic name Dicaeum is from the Greek δικαιον (dikaion), most likely referring to the scarab beetle, while the specific epithet pectorale is from the Latin pectoralis (of the breast).<p>There are two recognised subspecies of the olive-crowned flowerpecker:

Roadside Hawk
Rupornis magnirostris
Well-named, the common roadside hawk in tropical lowlands of East Mexico and Central and South America. Often seen on wires, phone poles, posts out in fields. Adult has staring pale eyes, streaked breast contrasting with barred belly. Immature streaked below, much like many other immature hawks, but its tail has broad and fairly even bands. Flies with rather quick, stiff wingbeats, recalling a Red-shouldered Hawk or an Accipiter; noisy flight display mainly in late winter-spring.
South Island Saddleback
Philesturnus carunculatus
A medium-sized songbird endemic to New Zealand, confined to predator-free offshore islands and South Island mainland sanctuaries. Glossy black plumage with distinct chestnut saddle across the back, which gives the bird its name. Note the bright reddish-orange wattles on either side of the bill. Juveniles have smaller wattles and are chocolate brown for their first year. Listen for distinct calls resembling a blaring “cheeet ta-chet ta-chet ta-chet” sound. Constantly moves noisily as it restlessly forages on the floor and through the canopy. Flicks over leaves and digs into rotting logs with its strong bill in search of invertebrates. Distinguished from Eurasian Blackbird by chestnut saddle and wattles.
Plain-breasted Piculet
Picumnus castelnau
Relatively plain piculet found in dense riverine and secondary vegetation along the Amazon and its tributaries in Peru, barely making it into southernmost Colombia and westernmost Brazil. Plumage generally pale below with a brownish back. Note the dark spots in the ear coverts; the short, sharp bill; and the glossy red feathers in the male’s crown. Song is a very high-pitched series of thin whistles, dropping at the end.
