      EN       Long-tailed Woodnymph Thalurania watertonii

    ... Ecology   It is restricted to lowland habitats such as coastal rainforest, cerrado, plantations and parks throughout its Atlantic forest range. It forages in the understorey and middle strata, usually on the periphery of vegetation on nectar and occasional invertebrates. Males defend territories against conspecific intruders and other hummingbirds. Breeding occurs between November and February.

    Threats      Widespread and continuing disappearance of lowland forest in north-eastern Brazil is likely to be causing declines, the Atlantic forests north of the Sao Francisco river having been drastically reduced, with less than 4% remaining by 1995. It seems able to accept man-made habitats as long as patches of forest or stands of scattered trees remain.  ...

       IUCN Status: Endangered

       Trend: Decreasing

       Habitat: Lowland humid forests, plantations, and parks

     ... Like its mythological namesake, the beautiful Long-tailed Woodnymph is a creature of forests — in this case, eastern Brazil's Atlantic Forest, a tremendously diverse habitat home to hundreds of bird species. Many of these, including Seven-colored Tanager, Banded Cotinga, and Pin-tailed Manakin, are found nowhere else.

    The endangered Long-tailed Woodnymph is just one of many of Brazil's birds that are threatened by habitat loss as forests give way to sugarcane fields, coffee plantations, and other agriculture. ...

     The long-tailed woodnymph (Thalurania watertonii) is a species of hummingbird in the family Trochilidae. It is found in humid forest in northeastern Brazil, where it is known from the states of Pernambuco, Alagoas, Sergipe and the northernmost Bahia.[3] It is usually thought to be widespread, but seen at low density in its increasingly fragmented range.[3] Its population is estimated to be around 1,000–2,500 individuals, currently in decline due to deforestation and habitat loss.[4]

     Description

    The long-tailed woodnymph is sexually dimorphic. The males are heavier, with significantly larger wings and tails, whereas the females have longer bills.[5] Males are approximately 11.8–13 centimetres (4.6–5.1 in) long, including 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). Individuals have a weight of 3.7–5.2 g.[3]

    Males have a conspicuous iridescent plumage in blue, green and purple. The crown and neck are bronze-green,[6] back is iridescent violet-blue, shining grass-green undersides and violet-blue flanks; Its long, deeply-forked tail is blue.[3] Female plumage is much more faint, allowing them to stay unnoticeable as they build nests and care for their young,[4] and a shorter, slightly forked white-tipped tail with a blue subterminal band and a pair of blue-green rectrices. Juveniles are similar to adult females.[3] ...
