Riparian Parrotlet
Forpus crassirostris
Tiny parrot with green body, short pointed tail, and pale bill. Males have blue wings and a green rump; females are all green. Highly gregarious. Found in light woodlands, forest edges, second growth, open habitats, and urban parks, but typically avoids dense forests. Found in western Amazonia, from Ecuador to central Brazil.
Identification
Riparian parrotlets are typically 12–13 centimetres (4.7–5.1 in) long and weigh about 28 grams (0.99 oz). Their bodies are mostly yellow-green. Eyes are dark brown and beaks and feet are light peach. Riparian parrotlets are sexually dimorphic: males have blue rumps and lower backs, with blue feathers along the leading edges of their wings and blue secondaries; primary coverts are blue-gray. Females have no blue feathers and a yellow-green belly.
Taxonomy
According to most studies, the riparian parrotlet is considered a subspecies of the cobalt-rumped parrotlet as Forpus xanthopterygius crassirostris. However, there are some studies that argue that its morphological differences support the existence of the large-billed parrotlet as its own species, F. crassirostris. There is continuing debate over the validity of this claim. Most taxonomic authorities (including the American Ornithological Society) do not recognize this change in classification.

Range and habitat
Riparian parrotlets are found in southeastern Colombia to northern Peru and western Brazil. There is a small population on São Sebastião Island. Though they do not fully migrate, it has been suggested that riparian parrotlets are altitudinal migrants: abundance of the species in lowland areas increased during winter and spring; this is likely because during these seasons, the main plants of the large-billed parrotlets' diet were budding and providing more food.<p>Riparian parrotlets tend to inhabit forest edges, riparian woodlands, and degraded or deforested areas.
Behavior
Like all members of the genus Forpus, riparian parrotlets are highly gregarious and are often seen in flocks of up to 100 birds.<p>Riparian parrotlets nest in tree cavities or similar places. They have been known to use the abandoned nests of rufous horneros and other unrelated species.<p>Females lay 3-7 small white eggs, which are incubated for approximately 18 days before hatching.<p>Riparian parrotlets feed on seeds, fruits, flowers, buds, and other plants. They favor palm, Cecropia sp., Handroanthus serratifolius flowers and nectar, and Ceiba speciosa fruits.
Conservation
This species is currently unrecognized by the IUCN Red List, so it does not have an official conservation status. Its populations are included in estimates of cobalt-rumped parrotlets, which are listed as Least Concern with a stable population. It is suggested that the population of riparian parrotlets is relatively low.

Golden-collared Manakin
Manacus vitellinus
A small, plump, and short-tailed manakin with a restricted range in Panama and western Colombia. Males are striking with a bright yellow throat and collar, a black cap, and a black back with greenish rump and belly. Females are entirely olive-green with red legs and dark bill and eye. Hybridizes with White-collared and White-bearded Manakins; hybrid males typically have yellow upper backs. Apparently no range overlap with similar Orange-collared Manakin. Occurs in dense understory of forest, second growth, and edges. Males gather in groups to display for females; otherwise most likely to be found at a fruiting tree or sitting quietly in the lower levels of forest.
Malabar Parakeet
Psittacula columboides
This striking parakeet is restricted to the forests of India’s Western Ghats. Bluish-gray male has a bright red upper bill and a black-and-blue collar. The greener female has an all-dark bill and a weaker black collar. Both sexes have blue in the wings and tail, though male’s is more prominent. Gives harsh, buzzy, high-pitched screeching, often as the birds shoot overhead. Favors forest and forest edge.
Brown Hornbill
Anorrhinus austeni
As the name suggests, a brown bird with a horn (casque) on its bill. Males are more brightly marked, with a white face and light orange-brown underparts. Females are darker brown with an almost black face. Both sexes have pale bills with small casques and a patch of bare blue-gray skin around the eye (smaller and darker in females). Inhabits lowland and hill forests. Gives high-pitched, rather raptor-like screams.
