Features of the Spatial Organization of the Behavior of Great Tits (Parus Major) and Robins (Erithacus Rubecula) During Testing in the «open Field» Instalation

In the “open field”, Great Tits and Robins had no significant differences in the locomotor activity, but their spatial distribution significantly differed. Robins spent time on the floor longer than Great Tits did. The latter, in comparison with the first, tended more strongly to the upper parts of the “open field” actively clinging to the grid on the ceiling and perched on the ledge in the upper part of the door. The proportion of time they spent in the middle part of the “open field” was similar in both species. Thus, in a neutral environment, Robins and Great Tits showed a pattern of behavior that largely reflected the structure of their locomotion and spatial distribution in the natural environment.
