Object-discrimination learning set data were obtained from 4 crows and 4- bluejays. Three of the 4- crows received $00 problems and demonstrated little or no learning set* The bluejays received 700 problems and did acquire a learning set as indicated by an average performance level of 72$ correct for Trial 2 on the last 100 problems of the experiment. Further analyses of hypothesis behavior (Levine, 1959) indicated that the crows made many errors based on position and stimulus preferences. The performance of the bluejays was characterized by consistent decreases in random responding and increases in the maximizing strategy (win-sbay~lose-shift with respect to object).

Agelaius phoeniceus (red-winged blackbird), Quiscalus quiscula (common grackle), and Sturnus vulgaris (European starling) are three of the most abundant bird species found in North America, and along with Euphagus carolinus (rusty blackbird) and Euphagus cyanocephalus (Brewer’s blackbird), make up a significant proportion of the avian population. Population trends of these four blackbird species and European starlings (EUST)were analyzed from the Christmas Bird Count (CBC) data collected between 1988 and 2008. Population analyses were conducted using linear mixed-effect regressions from the Lmer package of Program R. This approach was effective in modeling the population trends of widespread species with large populations. However, it was not as effective in modeling species with smaller populations and distributions. Only RWBL had significant change in population during the study period, showing a positive increase in mean count number of approximately 2.4% each year. Habitat selection showed some parallels among species.
