LC
Rusty-necked Piculet Picumnus fuscus



Justification

Justification of Red List Category
This species was thought to have a moderately small range which was suspected to be decreasing owing to habitat loss, and within which it was known from few locations. It was consequently classified as Near Threatened. Its range was remapped in 2010 and found to be well above the threshold at which a species may be considered Vulnerable. It has therefore been downlisted to Least Concern.

Population justification
This is a poorly known species and no population estimates are available.

Trend justification
This species is suspected to lose 12-20.7% of suitable habitat within its distribution over three generations (13 years) based on a model of Amazonian deforestation (Soares-Filho et al. 2006, Bird et al. 2011). It is therefore suspected to decline by <25% over three generations.

Distribution and population

Picumnus fuscus has a moderately small range in várzea forest along the río Guaporé (Iténez) in Beni and Santa Cruz (Noel Kempff Mercado National Park), Bolivia and Rondônia, Brazil (Short 1982, Parker and Rocha 1991, Killeen and Schulenberg 1998). It is poorly known, but observations suggest that it may be relatively common.

Ecology

It is restricted to várzea forest, where it may favour vine tangles and bamboo (Parker and Rocha 1991).

Threats

The río Guaporé is largely uninhabited, and almost continuously forested (Parker and Rocha 1991), but by 1996 there was increasing human colonisation of river banks in the west of the species' range (T. E. H. Stuart in litt. 1998).

Conservation actions

Conservation Actions Underway
It occurs in Noel Kempff Mercado National Park, Bolivia.

Conservation Actions Proposed
Effectively protect and manage protected areas where the species occurs. Monitor population at strongholds and search for the species in potentially suitable habitat at new sites. Study its ecology and dependence on várzea forest. Evaluate threats to its habitat.
