Endangered
Long-tailed woodnymph
Thalurania watertonii
Long-tailed woodnymph is a bird in the family Trochilidae (order Apodiformes) — Thalurania watertonii, recorded as Endangered.
Appearance
Males have a conspicuous iridescent plumage in blue, green and purple. The crown and neck are bronze-green, back is iridescent violet-blue, shining grass-green undersides and violet-blue flanks. Its long, deeply-forked tail is blue. Female plumage is much more faint, allowing them to stay unnoticeable as they build nests and care for their young, and a shorter, slightly forked white-tipped tail with a blue subterminal band and a pair of blue-green rectrices.
Males are approximately 11.8–13 centimetres (4.6–5.1 in) long, among them a tail of 6 centimetres (2.4 in) cm. While females measure roughly 10–11 centimetres (3.9–4.3 in) in length, with a tail of 3.6 centimetres (1.4 in).
Range and habitat
The species is thought to be found only in the Atlantic Forest. The long-tailed woodnymph inhabits coastal lowland habitats such as coastal rainforest, cerrado, plantations and parks throughout its Atlantic forest range, from sea-level to 550 metres (1,800 ft). It is found in humid forest in northeastern Brazil, where it is known from the states of Pernambuco, Alagoas, Sergipe and the northernmost Bahia.

Diet and breeding
The long-tailed woodnymph feeds on the nectar of flowering vines, cacti, epiphytes, trees and bushes, occasionally foraging on invertebrates captured in the air. Breeding takes place between November and February.
The woodnymph builds a cup-shaped nest made of fine rootlets and moss, tightly tied together by a spider's web. The nest is attached to a horizontal branch in a shrub or small tree, usually protected by overhanging leaves, 1.5–2.5 metres (4.9–8.2 ft) above the ground.
In crisis
Its population is estimated to be around 1,000–2,500 individuals, currently in decline due to deforestation and habitat loss. Long-tailed woodnymph is listed as endangered by the IUCN Red List, due to the ongoing reduction of its populations, mainly due to the extensive and continuing loss of habitat and the depletion of lowland forests in north-eastern Brazil. The population is severely fragmented, with the total population estimated to be less than 2,500 individuals, and each subpopulation contains less than 250 of them.
CITES lists this taxon on Appendix II. Confirm the current appendix on the CITES checklist.
