Figure 3

Responsiveness of current breeders with dependent infants (DI) versus independent infants (II) during (a, c) own infant vocalization tests (OV) and versus noncurrent breeders (NI) during (b, d) unfamiliar infant vocalization tests (UV). (a, b) Latency to explore stimulus. (c, d) Latency to enter stimulus nestbox. Means are shown with SE (box) and SD (vertical lines). Lines spanning different histograms indicate categories of breeders between which differences were significant at P <0.05.
