Figure 2 in Impacts of food-based enrichment on behaviour and physiology of male greater rheas (Rhea Americana, Rheidae, Aves)

Figure 2. Exhibition of behaviours "walking" (F = 31.51, p <0.01, N = 30, DF = 2), "foraging" (F = 28.31, p <0.01, N = 30, DF = 2), "eating faeces" (F = 6.01, p = 0.05, N = 30, DF = 2) and "pacing" (F = 32.06, p <0.01, N = 30, DF = 2) by greater rheas in the three phases of a food enrichment study in the enclosure at the Belo Horizonte Zoo, Brazil. Different letters represent treatments that significantly differed between each other. b = baseline; e = enrichment; p = post-enrichment.
