Imitative pecking by budgerigars, Melopsittacus undulatus, over a 24 h delay
On video, budgerigars observed a conspecific demonstrator depressing a stopper by pecking or by stepping and then feeding from the box below. The observers were given access to the stopper, immediately after observation or following a 24 h delay, and we recorded the proportion of their stopper removal responses that were made by pecking and by […]
Avoidance-related behavioural variables and their relationship to milk yield in pasture-based dairy cows
The behavioural responses of Jersey, Friesland and crossbred cows to humans were determined by recording their avoidance distance scores (AD), exit speed (ES), pen score (PS), pen behaviour score (PBS), platform score (PLS), and the occurrence of kicking (KCK) and stepping (SPG) during milking in four different seasons (hot-wet, hot-dry, cool-dry and post rainy seasons).
