Reddish Hermit
Phaethornis ruber
Tiny and charismatic hermit hummingbird. Note a very contrasting black mask. Dark-olive above and cinnamon below and on the rump. Males have an incomplete black breast band and a shorter tail and wings than females. Common in the lower strata of forests and forest edges where it is fond of Heliconia flowers.

The reddish hermit is 8 to 9 cm (3.1 to 3.5 in) long and weighs 1.8 to 3 g (0.06 to 0.11 oz). All subspecies are generally dark green and rufous on the upperparts and cinnamon rufous on the underparts. Males have a black band on the chest and the tail feather have narrow white or reddish tips. Females have lighter underparts than the males. P. r. episcopus is about the same size as the nominate but has orange-rufous rather than cinnamon-rufous underparts and white tips to the tail. P. r. nigricinctus is the smallest subspecies; it has the richest rufous underparts. P. r. longipennis is the largest subspecies. It has a whitish chin and its central tail feathers have rufous tips.
分类信息
In 1743 the English naturalist George Edwards included a picture and a description of the reddish hermit in his A Natural History of Uncommon Birds. He used the English name "The little brown huming-bird". Edwards based his etching on a specimen owned by the Duke of Richmond that had been collected in Suriname. When in 1758 the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the tenth edition, he placed the reddish hermit with the hummingbirds in the genus Trochilus. Linnaeus included a brief description, coined the binomial name Trochilus ruber, and cited Edwards' work. The specific epithet ruber is a Latin word meaning "red". The type locality is Suriname. The reddish hermit is now placed in the genus Phaethornis that was introduced in 1827 by William Swainson. The reddish hermit has sometimes been considered conspecific with the white-browed hermit (P. stuarti).<p>Four subspecies are recognised:<p>Some introgression has been noted between the nominate P. r. ruber and P. r. longipennis. P. r. episcopus and P. r. nigricinctus might actually be separate species but data to confirm the hypothesis are lacking. The population of P. r. ruber in southeastern Brazil has been proposed as a separate subspecies P. r. pygmaeus but its apparent differences are within the range of variation in the rest of ruber.

行为
The reddish hermit is assumed to be sedentary.<p>The reddish hermit is a "trap-line" feeder like other hermit hummingbirds, visiting a circuit of many species of flowering plants for nectar. It also consumes small arthropods. Nectar robbing by piercing the base of a flower has been regularly observed in southeastern Brazil.<p>The reddish hermit's breeding seasons vary throughout its large range; in general in the north it is within May to October and in the south within October to February. The nest is a cone-shaped cup made of plant fibers, mosses, lichens, other plant material, and spider web. It is attached under a drooping leaf. The clutch size is two eggs and the female alone incubates them.<p>The reddish hermit's song is "a high-pitched phrase repeated incessantly with clear pauses between phrases...evenly-spaced, slightly descending, single notes followed by a number of accelerating descending notes, e.g. 'tsee....tsee...tsee...tsee.tse.tsitsi'." It frequently sings for long periods at leks. It has "long whining calls" made while hovering and a "stip!" flight call.

White-sided Hillstar
Oreotrochilus leucopleurus
Small hummingbird of the Andes from southern Bolivia through Argentina into central Chile; found in rocky and shrubby valleys, villages, and any open or semiopen areas with flowers. Often builds nest under eaves of buildings or bridges: a bulky cup of plant material and wool to insulate against cold nights. Fairly common. Readily identified in most of range by extensively white tail. Male has an emerald green gorget and a broad blue-black stripe on belly. Female is rather drab, but note slightly decurved bill, spotted throat, and tail pattern.
Spot-bellied Eagle-Owl
Ketupa nipalensis
Immense and imposing owl of dense wet lowland and hill forests. Silver-gray adult is majestic, with a large yellow bill, black eyes, and sweeping sidewards-facing “horns.” Juvenile is much paler, almost white, with shorter tufts. Gives deep echoing hoots. Primarily nocturnal, but will on occasion hunt by day; takes prey as large as small deer.
Gray-throated Martin
Riparia chinensis
A small gray-brown swallow with pale white underparts. It has a gray-brown chin, throat, and upper breast and does not show any kind of breast band. Tail is short, square-ended or sometimes marginally forked. It is mainly found around slow-flowing rivers, lakes, wet grasslands, and other wetland habitats; mostly seen in the air but sometimes sitting on wires or on the ground or on cliffs while breeding.
