Warbling Vireo (Productivity)

Predictive model of the number of Swainson's Thrush adult captures expected during the operation of a standard Monitoring Avian Productivity and Survivorship (MAPS) station (http://www.birdpop.org/maps.htm ). EBird observations (all historical records, May-Jul inclusive) were superimposed upon the predictive model for visual validation of predictions (yellow dots).

Warbling Vireo predictive productivity model states that more adult individuals are captured in medium shrub coverage rather than high shrub coverage, and lower elevations.

Bozdogan's ICOMP information complexity index selected the following model

Warbling Vireo Productivity model Warbling Vireo station lifetime productivity (STAPI) (log transformed) ranged between -0.061 and +0.300 with a mean value of +0.120 and a median value of +0.095. ________________________________________

 Model 2 (3 parameters) Warbling Vireo station lifetime productivity (STAPI) (log transformed) was a function of:
a) INTERCEPT (0.38275),
b) GTOPO30_AL (-0.03663) - elevation (m), ranged between +5.304 and +8.423 (95% CL) with a mean value of +6.863 and a median value of +7.137,
c) NLCD06SH5KP (-0.00738) - percent shrubland cover, 990m-resolution in a landscape context of 5km radius, ranged between +1.045 and +3.879 (95% CL) with a mean value of +2.462 and a median value of +2.645.
