dc.description.abstract | The objectives of this study were to develop standardized techniques for evaluating mourning dove breeding habitat along call-count transects from a vehicle ("windshield approach"), and identify those habitat parameters correlated with dove densities obtained from call-count surveys in Texas. A habitat classification was developed in which 562 habitat types were recognized. Habitat type was defined as a unique combination of ground cover height and composition, canopy composition, and spatial distribution (physiognomic class). Structural features (fences, powerlines, windbreaks, etc.) were also considered. Call-count and habitat surveys were conducted on 133 random transects in Texas between 20 May and 10 June 1976. Linear distance of each habitat type intersecting a transect and number of structural features within 0.8 km were recorded. Habitat parameters were analyzed for correlations with call counts using stepwise multiple regression. Habitat interspersion and diversity were included. Analyses were conducted by transect interval (1.6 km) and transect within ecological areas and statewide. Simplifications of the habitat classification were evaluated based on R-squares and number of parameters within models. The simplified habitat classification (26 habitat types) including physiognomic class with canopy composition and cropland divisions was selected. Estimates of ground cover height and composition were not necessary to effectively evaluate breeding dove habitat.. | en |
