Demography and Populations

The first population estimate for the White-lored Warbler was given by López-Lanús and Renjifo (2002), based on the abundances of similar species (Myiothlypis nigrocristata Black-crested Warbler and Myiothlypis luteoviridis Citrine Warbler) and was estimated to be between 4500 and 49,500 individuals. Utría-Ortega (2012) produced stratified elevation density estimates based on standardized transect observations in the San Lorenzo Important Bird Area. He estimated a population of between 35209 and 53113 individuals just for this 570 km2 area. This estimate gives a prospect of a much larger population for the species in the whole of the Sierra Nevada de Santa Marta (Utría-Ortega 2012).

Interestingly, Utría-Ortega (2012) also detected differences in the abundance of White lored-Warbler along the elevation gradient. The elevation range where they are more abundant is from 1000 to 2000 m. Above that range, the species abundance decreases significantly (Utría-Ortega 2012). The population estimates from this study took into account the variation in abundance by elevation.
