Abstract

Long-term bird population changes in response to natural or anthropogenic factors have been relatively well documented in the temperate zone, but rarely in the tropics, where there are few long-term data sets. Here, we analyze a 25-yr sequence of records of two species of Lophura pheasants, Siamese Fireback L diardi and Silver Pheasant L. nycthemera in Khao Yai, Thailand's oldest national park. These data suggest that the number and proportion of detections of the lowlands-inhabiting L. diardi have increased significantly in relation to those of the higher elevation inhabitant L. nycthemera. Environmental factors mediated by changing climate are the most plausible explanation for the changing proportions of sightings of the two species. Further work is needed to explore in detail microhabitat selection of these birds and whether changes in microsite conditions on the forest floor or other factors are driving the observed distribution. Long-term monitoring of the avifauna along an elevational gradient is also recommended in tandem with increased monitoring of local climatic conditions.
