Patterns of Alloparental Care Helpers are not just resident on the home territory, but actively assist the family by 1) guarding pups, 2) feeding pups, 3) socializing pups, 4) feeding the lactating female, and 5) defending the territory. The time budget of parents without helpers differs from parents with helpers. In five silverbacked pairs, each of which raised a litter without helpers, pups were left alone up to 40% of the time (267 h of observations). During the first 3 weeks mothers spent a major- ity of time in the den, which may have prevented hypothermia. When the pups were about three weeks old the mothers decreased the time at the den from 90% to approximately 35%. Concurrently the mates started spending more time within 100 m of the Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Eisenberg, John Frederick; Kleiman, Devra G; American Society of Mammalogists.
