KBO 2003 Bird Nest Search Data

This dataset contains Klamath Bird Observatory's 2003 nest monitoring data. This data was analyzed to assess nesting behavior and nest success of 8 focal species in various habitats. This was part of a study that compared bird abundance and nesting to determine whether habitat islands retained within timber harvests (Wildlife Protection Areas, WPAs) were effective in providing habitat for birds in the years shortly after harvest. Two years of point counts revealed that bird abundance in WPAs was more similar to abundance in clearcuts than mature forests, and that species richness did not differ between clearcuts, WPAs, clearcuts and WPAs combined, and mature forests. Nest monitoring results showed WPAs within clearcuts provided nesting habitat similar to clearcuts and WPAs within thins contained less nesting species than thins. Results from both abundance and nesting data concur that WPAs are providing habitat for the forest species Cassin’s Vireos (Vireo cassinii) and two habitat generalists; Western Tanagers (Piranga ludoviciana) and Yellow-rumped Warblers (Dendroica coronata).
