Scientific Name: Thalurania watertonii
Species Authority: (Bourcier, 1847)
Common Name(s):
English Long-tailed Woodnymph

Assessment Information [top]

Red List Category & Criteria: Near Threatened ver 3.1
Year Published: 2012
Date Assessed: 2012-05-01

This species has a moderately small and severely fragmented range within which is the population is suspected to be declining owing to habitat loss (del Hoyo et al. 1999). It is consequently classified as Near Threatened.

Geographic Range [top]

Range Description: Thalurania watertonii is confined to eastern Pará (probably erroneous), Pernambuco, Alagoas, Sergipe and northern Bahia, north-eastern Brazil (Pacheco and Whitney 1995) where it is common but presumably declining due to habitat loss.

Population [top]

Population: The global population size has not been quantified, but the species is described as common throughout its range (del Hoyo et al. 1999).
Population Trend: Unknown

Habitat and Ecology [top]

Habitat and 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.

Systems: Terrestrial

Threats [top]

Major Threat(s): 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.

Conservation Actions [top]

Conservation Actions: Conservation Actions Underway
CITES Appendix II. It occurs in Monte Pascoal National Park and Pedra Talhada State Park.

Conservation Actions Proposed
Effectively protect and manage protected areas where the species occurs. Study its ecology and its ability to persist in degraded and fragmented habitats. Attempt to obtain an accurate estimate of its population size and trends.
