1981 Christmas Count

Nebraska Bird Review

Eighty-eight species (fourteen less than last year) were reported in the 1981 Christmas Count, and one species (two less than last year) was reported present during the count week but not recorded on the count day on any count. Seven localities reported this year, the same as last year, but Grand Island and Tri-state replaced Kearney and Hastings. Two additional races were reported, the same as last year. The individual count this year was 64,054, compared to 317,910 last year. The drop in the Snow Goose (178,719) and Mallard (81,291) counts more than accounts for the difference. Nineteen species were …

Stimulus Control Exerted By Remember Cues Over Processing In Pigeons’ Short-Term Memory, Patricia E. Hernandez Torres

Theses and Dissertations (Comprehensive)

The aim of the present research was to provide further evidence regarding the role of remember cues on pigeon short-term memory. The first two experiments were conducted to determine whether, using a single cuing procedure, control over delayed matching-to-sample (DMTS) performance could be demonstrated by establishing a no cue condition as an implicit cue to forget. In Experiment 1, subjects were provided with training in a procedure where both forget cue (F) and no cues indicated the omission of the comparison stimuli at the end of the delay interval. In Experiment 2, naive subjects were trained with remember (R) and …
