Justification of Red List category

This species's population size is suspected to be declining moderately rapidly as a result of ongoing deforestation. For this reason, it is listed as Near Threatened.

Population justification
It is not considered common (del Hoyo et al. 2004). The global population size has not been estimated directly. Based on the first quartile and median recorded population densities of congeners (6.7 and 16 individuals per km²), the estimated area of tree cover with at leats 50% canopy cover within the mapped range in 2020 (c.773,000 km²; Global Forest Watch 2021), and assuming tree cover to be 10-40% occupied, the population size is suspected to fall within the range 500,000 - 5,000,000 indivduals, roughly equating to 300,000 - 4,000,000 mature individuals.

The number of subpopulations is not known. Much of the habitat in the east of the species's range is extremely fragmented, so there are likely to be a large number of isolated subpopulation.

Trend justification
The species appears to have been extirpated from some areas that have been extensively deforested (Henriques and Dantas 2009). Remote sensing data on tree cover loss indicates that approximately 9% of tree cover was lost from within the species's range over the past ten years to 2020 (Global Forest Watch 2021). Based on the rate of forest loss over the period 2016-2020, it is projected that up to 14% of tree cover may be lost from the species's range over the next decade. Research in northeast Brazil has indicated that degradation led to an additional 51% loss of biodiversity (Barlow et al. 2016). Although this species shows a degree of tolerance of habitat degradation and fragmentation (A. Lees in litt 2011), it is precationarily suspected to undergo a population reduction of 5-25% over the next ten years.

Xipholena lamellipennis is endemic to Amazonian Brazil, south of the Amazon river, from eastern Amazonas and the lower Rio Tapajós, Pará, east to north Maranhão, and south into northern Mato Grosso and Tocantins (Pascoal et al. 2018, GBIF.org 2021).

This is a canopy species of humid lowland forest, occurring up to 400 m (del Hoyo et al. 2004). It shows some tolerance to secondary habitats and fragmentation (Hohnwald 2009, A. Lees in litt. 2011). Its diet is poorly known, but it is likely to feed on fruits (del Hoyo et al. 2004).

The primary threat to this species is accelerating deforestation in the Amazon basin as land is cleared for cattle ranching, soy production, selective logging and escaped fires, facilitated by expansion of the road network (Soares-Filho et al. 2006, Bird et al. 2011).

Conservation Actions Underway
It occurs in a number of protected areas.

Conservation Actions Proposed

Carry out surveys to determine the species's range limits, population density, population size and population trends.
Expand the protected area network to effectively protect IBAs. Effectively resource and manage existing and new protected areas. Enforce legislation to prevent clearance of forest.

19-20 cm. Medium-sized, dimorphic cotinga. Has a distinctive wide-based and somewhat flattened bill, hooked at the tip. Male is glossy purplish black, apart from the tail and most of the wings, which are white. Female is ash grey above and paler below, with black on the wings and tail.
