Justification of Red List Category
This species is Endangered because it has a very small range, which is presumably declining significantly in response to changing agricultural practices and conversion to plantations.
The population is estimated to number 1,000-2,499 individuals based on an assessment of known records, descriptions of abundance and range size. This is consistent with recorded population density estimates for congeners or close relatives with a similar body size, and the fact that only a proportion of the estimated Extent of Occurrence is likely to be occupied. This estimate is equivalent to 667-1,666 mature individuals, rounded here to 600-1,700 mature individuals.
A moderate and ongoing population decline is suspected owing to rates of habitat loss.
Phyllomyias urichi occurs on the northern Cordillera de Caripe (on the borders of Anzoátegui, Sucre and Monagas) and the westernmost Paria Peninsula (Sucre) in north-east Venezuela (Kirwan and Sharpe 1999; Phelps and Phelps 1950; Ridgely and Tudor 1994). In the Cordillera de Caripe, specimens have been taken from four localities (Phelps and Phelps 1950; Hilty 2003; Sharpe 2008, 2015), but there have been few recent sight records. There is a single sight record from Cerro Humo on the Paria Peninsula (Kirwan and Sharpe 1999).
It appears to inhabit montane, humid forest, with all records at elevations of 800-1,100 m (C. J. Sharpe, J. P. Rodríguez and F. Rojas-Suárez in litt. 1999). Basic biology almost unknown (Fitzpatrick and Sharpe 2015).
There has been widespread clearance for agriculture and pasture in the Cordillera de Caripe. The forests here have been reduced by 60% over the past 25 years (Sharpe 2008). Even in El Guácharo National Park there is clearance, repeated burning and understorey removal for coffee (Boesman and Curson 1995). The slopes of Cerro Negro are largely bare with the more obvious forest patches actually shade-coffee plantations (Boesman and Curson 1995). There is conversion to coffee, mango, banana, and citrus plantations in the Serranía de Turimiquire, but extensive forested areas remain (Colvee 1999, Sharpe in litt. 2011). On Cerro Humo, increases in cash-crop agriculture, especially the cultivation of ocumo blanco since the mid- to late 1980s, have resulted in uncontrolled burning and forest degradation.
Conservation Actions Underway
It is formally protected by Paria Peninsula and El Guácharo National Parks. The latter reserve was expanded to include a further 500 km2 of largely undisturbed forest (Gabaldón 1992). It is considered nationally Endangered in Venezuela (Sharpe 2008, 2015).
