The movement and landscape use of Blue Cranes in the Western Cape
… and distance travelled throughout the day of breeding and non-breeding cranes to determine whether the breeding status/season influences their ranging behaviour. There was no significant difference of the home range size between breeding cranes and non-breeding cranes (p > 0.05). There was …

Vigilance behavior and land use by sandhill cranes (<i>grus canadensis</i>)
… tall alert posture with differences in gender, breeding status, time of day, traffic on the nearest road, and human disturbances. The southern Michigan populations of sandhill cranes nest closer to roads and houses than they have in the past and do not preferentially avoid them. They favor …

Odour signals contain multi-modal information in the banded mongoose (Mungos mungo).
… such as relatedness, health parameters and breeding status from potential mates. Although visual and auditory signals are utilised, scent is a crucial and ancient form of communication yet, with the exception of certain model systems, we understand little of how it functions in wild mammals. …

THE ROLE OF PROLACTIN AND REPRODUCTIVE EXPERIENCE IN THE ONSET OF PARENTAL CARE IN THE ZEBRA FINCH (TAENIOPYGIA GUTTATA)
… (PRL) levels are generally low during non-breeding times, but significantly increase during late incubation and early post-hatch care. Because of this pattern, PRL has been suggested to be involved in the initiation of parental care in birds, but rarely has this hypothesis been causally …

Know your place - Social network analysis in cooperatively breeding white-winged choughs (Corcorax melanorhamphos)
Cooperative breeding is a specialised type of social system in which individuals work together as a group to raise young. This breeding system entails variable costs and benefits for individuals based on their position in group social structure. Social network analysis has become an important tool …

Behavioural ecology of the Redbilled Woodhoopoe Phoeniculus purpureus in South Africa
… social system and high level of inbreeding of Redbilled Woodhoopoes have evolved primarily in response to environmental constraints on dispersal, rather than by particular benefits that arise from group living. Therefore, the habitat-saturation hypothesis best explains group living …

Ecological and molecular basis of differential resource use in populations of burying beetles Nicrophorus vespilloides
… whether this fierce competition for a carcass breeding resource has driven the evolution of beetles that specialise in breeding on dead mammals or dead birds. With field experiments at three different woodlands, I tested for evidence of a bias in the type of carcass favoured by Nicrophorus …
