Ecuadorian Seedeater
Amaurospiza aequatorialis
Scarce and very local. A rather plain, easily overlooked, small seed-eating bird. Usually found as singles or pairs in association with seeding bamboo in forested areas from lowlands to highlands, perhaps most numerous at mid-elevations. Male is dull dark bluish and female is rich brown overall. Note the stout grayish bill with curved culmen. Listen for sharp metallic chips and sweet warbling song.
Identification
The male Ecuadorian seedeater is mostly a pale slate blue; its crown is a lighter indigo. The female's upperparts are cinnamon and the underparts tawny.
Taxonomy
The Ecuadorian seedeater was formally described in 1888 by the English ornithologist Richard Bowdler Sharpe based on specimens collected in Ecuador. He coined the binomial name Amaurospiza aequatorialis. The specific epithet is Late Latin for "equatorial", a name commonly used for species from Ecuador, ecuador means "equator" in Spanish.<p>In 2015 the IOC split the subspecies Amaurospiza concolor aequatorialis from the blue seedeater (Amaurospiza concolor sensu lato) as the Ecuadorian seedeater (Amaurospiza aequatorialis) and renamed A. concolor Cabanis's seedeater. The decision was based on a molecular phylogenetic study published in 2014. However, the South American Classification Committee of the American Ornithological Society (AOS) had previously rejected the split, and as of May 2021 the AOS North American Committee has not considered it and the Clements taxonomy has not adopted it. Confusingly, BirdLife International uses the scientific name A. moesta for blue seedeater, but the IOC, AOS, and Clements assign that binomial to blackish-blue seedeater. The BirdLife account encompasses what are now Cabanis's, Ecuadorian, and blackish-blue seedeaters.<p>The Ecuadorian seedeater is monotypic.

Range and habitat
The Ecuadorian seedeater is found on the west slope of the Andes from southwestern Colombia's Nariño Department through western and central Ecuador into northern Peru, perhaps as far south as the Department of Piura. It inhabits openings in and edges of humid montane and secondary forest and is closely associated with bamboo. In elevation it ranges mostly from 1,100 to 2,300 m (3,600 to 7,500 ft) and locally as low as 800 m (2,600 ft).
Behavior
The Ecuadorian seedeater's diet includes insects, seeds, and bamboo shoots.<p>No information about the Ecuadorian seedeater' breeding phenology has been published.<p>An example of the Ecuadorian seedeater's song is [1]. Its call is [2].

Other Birds
Velvet Flycatcher
Myiagra eichhorni
Male is entirely glossy black with a slightly erect crest. Female has a rufous back and pale underparts; head color varies between islands, being dark on New Ireland, New Hanover, and New Britain, and pale on Djaul. Prefers primary forest and undisturbed second growth. Song is a series of loud, piercing whistles. Call is a buzzing nasal churr.
Anjouan White-eye
Zosterops anjuanensis
A small, sharp-billed warbler-like bird. Note the yellow patches on the throat and undertail and the bold white spectacles around the eye. Common on the island of Anjouan in the Comoros in habitats with woody vegetation, including remnant forest patches, plantations, woodland, scrub, and gardens. Usually found in hyperactive flocks. In its small range, easily identified by the white spectacles. The most common calls are a high-pitched, rising rattle and a descending “chew” note, which is also the main component of the quiet, chatty song.
Bridled Tern
Onychoprion anaethetus
Tropical tern with gray back, black cap, and white forehead. Nonbreeding and immatures have a messy dark nape. Most similar to Sooty Tern but paler gray above with more extensive white tail edges, paler undersides of flight feathers, as well as longer and more slender eyebrow. Also compare with the paler Gray-backed Tern. Bridled Tern is found in warm tropical waters worldwide. It breeds on islands, usually concealed by a large rock or bush. Otherwise, usually stays far offshore, often seen perching on floating wood or debris. Rarely seen near land except when blown off course by a hurricane.
