Wattled Ploughbill
Eulacestoma nigropectus
A fairly small, plump bird with a unique bill shape of montane forest. Male is yellow-green with black wing, chest, and two large, pink, fleshy wattles beside the bill. The female is olive-green with paler underparts. Forages low and especially likes climbing bamboo. Uses its strong bill to strip wood and dig into branches. Male plumage is unique, but even with the female’s non-descript plumage, the bill shape should be a give-away. Voice, a single, long, high-pitch note.
识别特征
It is approximately 12.5 to 14 cm (4.9–5.5 in) , olive-brown songbird with a strong, thick, wedge-shaped black bill. It weighs 19–22 g (0.67–0.78 oz). The sexes are different. The male has black underparts, an almost golden forehead, black wings with golden scapulars, and a pair of large circular pink wattles on the cheek. The female has olive green plumage and pale olive below. Only the adult male has wattles.
分类信息
The wattled ploughbill was formally described in 1894 by the English naturalist Charles Walter De Vis. He introduced a new genus Eulacestoma and coined the binomial name Eulacestoma nigropectus. The genus name combines the Ancient Greek eulaka meaning "ploughshare" with stoma meaning "mouth". The specific epithet is from the Latin niger meaning "black" and pectus meaning "breast".<p>The wattled ploughbill was long thought to be related to the whistlers (Pachycephalidae), and shriketits (formerly Pachycephalidae, now often treated as its own family). In particular the wattled ploughbill and crested shriketit share a similar large bill. Genetic studies have shown that these birds are not closely related, and the wattled ploughbill is instead more closely related to the sittellas. Because of its genetic and morphological uniqueness, in 2014 Richard Schodde and Leslie Christidis placed it in its own monotypic family Eulacestomatidae.<p>The wattled ploughbill is a monotypic species, meaning it has no accepted subspecies. A subspecies clara has been proposed, but it is not reliably distinct from other birds in this species.

行为
The diet consists mainly of insects. The species feeds from the forest floor to up to 10 m (33 ft), from the understory to the mid-level of the forest. It particularly favours groves of bamboo as a micro-habitat for feeding. It forages on branches and twigs, gleaning insects from the surface and prising off bark to expose prey. The species will readily join mixed-species feeding flocks.
保护状况
Widespread throughout its large range, the wattled ploughbill is evaluated as least concern on the IUCN Red List of Threatened Species.

Freckled Duck
Stictonetta naevosa
Very finely-speckled dark-grayish duck with a dark eye and an obvious peaked crown. Beak is strongly curved like a ski-jump. Breeding males have a red base to their bill. Upper-wing is dark, while under-wing is paler gray. When perched, distinguish from Hardhead (which have a pale belly patch). Generally uncommon; found beside inland waterholes and ponds. More reliable inland, but can be common one year and absent the next from any given location.
Rufous Hummingbird
Selasphorus rufus
Adult males are almost entirely orange with bright white chest and some green on the back (can be solid green like Allen's Hummingbird). Throat is iridescent, and depending on the light, can look anywhere from red to orange to yellow to lime green. On females and immatures, look for orange on sides and tail to separate from Anna's and Black-chinned. Found in a variety of wooded habitats; more common in migration in suburbs, meadows, and other brushier areas. Feeds on nectar and tiny insects.
American Robin
Turdus migratorius
Fairly large songbird with round body, long legs, and longish tail. Gray above with warm orange underparts and blackish head. Hops across lawns and stands erect with its bill often tilted upward. In fall and winter, forms large flocks and gathers in trees to roost or eat berries. Common across North America in gardens, parks, yards, golf courses, fields, pastures, and many other wooded habitats.
