Indigo-capped Hummingbird
Saucerottia cyanifrons
Medium-sized hummingbird with restricted range in central Colombia. Distinctive: all green with a contrasting blue crown, white leg puffs, and reddish lower mandible. Occurs in the middle to upper levels of forests, edges, and shrubby gardens from around 1,000 to 2,000 m. Visits feeders.
Identification
The indigo-capped hummingbird is 7 to 10 cm (2.8 to 3.9 in) long and weighs about 5 g (0.18 oz). Both sexes have a black bill with a red base to the mandible. The adult male has an indigo-blue crown, shining green upperparts with a bronze to coppery gloss on the rump, and bronze to bluish black uppertail coverts. Its tail is deep steel blue. Its underparts are glittering golden green with undertail coverts that vary from bronze-green to dark bluish with whitish edges. The adult female's crown is turquoise-blue towards the rear and its throat feathers have a grayish bar near the end. Juveniles are like the female with a grayer belly.
Taxonomy
The indigo-capped hummingbird was formerly placed in the genus Amazilia. A molecular phylogenetic study published in 2014 found that the genus Amazilia was polyphyletic. In the revised classification to create monophyletic genera, the indigo-capped hummingbird was moved to the resurrected genus Saucerottia. However, BirdLife International's Handbook of the Birds of the World (HBW) retains it in Amazilia.<p>The indigo-capped hummingbird is monotypic.

Range and habitat
The indigo-capped hummingbird is found in north and central Colombia, principally in Norte de Santander Department, the Magdalena River valley, and the upper Cauca River valley. It inhabits semi-open to open landscapes such as the edges of wet forest, savanna, shrubby areas, plantations, and gardens; most of these are fairly dry. It is most common between 1,000 and 2,000 m (3,300 and 6,600 ft) but regularly occurs down to 400 m (1,300 ft) in the breeding season and sometimes to near sea level. It also rarely occurs as high as 3,000 m (9,800 ft).

Behavior
The indigo-capped hummingbird apparently makes seasonal elevational movements in response to availability of flowering plants.<p>The indigo-capped hummingbird forages for nectar and small arthropods at all heights of its habitat, but mostly in the uppermost stratum. Though it sometimes gathers with other indigo-capped hummingbirds at flowering trees, it is usually territorial and defends feeding patches from hummingbirds and other nectarivorous birds like bananaquits (Coereba flaveola). It usually captures arthropods by hawking from a perch in the canopy but does so occasionally by gleaning from foliage.<p>The indigo-capped hummingbird's breeding season apparently extends from April to at least July. The nest is a cup of moss, cobweb, and lichen. The clutch size is two eggs but nothing else is known about the species' breeding phenology.<p>The indigo-capped hummingbird's song is "a repeated buzzy, squeaky phrase 'tzuk-keee ... tsrp'." It also makes "a high, sharp 'tsit'" call, sometimes in a series.

Drab Seedeater
Sporophila simplex
Well-named seedeater found in arid scrub and adjacent farmland in western Peru and southwestern Ecuador. Its best field marks are the distinct wingbars and bill color (pinkish on breeding males, nearly black on other individuals). Bill is smaller and less bulbous than that of Parrot-billed Seedeater. Sometimes found alone, but loose flocks may converge on areas with abundant food, such as fields of seeding grass. Males often sing a short series of buzzy notes.
Flores Jungle Flycatcher
Eumyias oscillans
A dark flycatcher of denser montane forest. Dingy brown above with a rufous wash to wings, rump, and tail. Dark gray throat and breast, whitish belly, and a buff base to the undertail. Singles and pairs are inconspicuous in the undergrowth and midstory, often joining mixed-species flocks. Separated from Asian Brown Flycatcher by larger size, entirely dark bill, duller underside, and lack of a white throat. Sings a jumbled, high-pitched warbling: “tiritirtir-tu…”
Spot-billed Pelican
Pelecanus philippensis
A large pale waterbird with a hefty pinkish pouched bill marked with diagnostic dark spots on the upper mandible. The head is grizzled with a hint of a shaggy crest and the back of the neck is dark. Rings of bare skin around each eye that make this bird look like it's wearing glasses. In breeding plumage, the rump, sides, and underwing coverts are salmon pink and the breast ochre yellow. Often seen in large lakes and estuaries fishing in groups. Nests in noisy colonies in trees bleached by droppings.
