Carnivores: Hide food around enclosure
A small replicated, before-and-after study in 2007 of maned wolves Chrysocyon brachyurus in a research centre in the USA found that when dead mice were hidden around the enclosure, activity rates increased for three out of four wolves and exploratory behaviours increased for all wolves compared to when no mice were hidden. There was an increase in activity (proportion of active time per individual: 0.6, 0.8 and 0.7) and exploratory rates (events/minute for each individual: 0.9, 1.3, 1.7 and 2.3) when presented with hidden mice compared to no enrichment (proportion of active time per individual: 0.3, 0.2 and 0.5; exploratory: 0.13, 0.06, 0.07 and 0.05 events/minute). Four individually housed wolves were observed daily using focal sampling during 30-minute observation sessions for two weeks of no enrichment, two weeks of hiding mice, a further two weeks of no enrichment and two weeks of boomer balls.
