Nursing, sustenance, and exploratory activities. For each data set, the first 12 PNDs were grouped into 3-day bins for analysis and for graphing: PND1–3 = PND Bin 1, PND4–6 = PND Bin 2, etc. (A) BP-mothers and SMs nurse pups at essentially equal rates. (B) There are also no differences in sustenance-related eating and drinking activities. (C) BP-fathers engage in a slightly higher frequency of exploratory activities (wandering, gnawing, digging, climbing, jumping) than BP-mothers; BP-mothers have a trend toward a higher rate than SMs (p = .051). Bars represent mean ± SEM. *p < .05, NS, not significant.
