Summary:
Parents of millennials still
living at home aren't the only ones with children that refuse to leave. Many
animal species have adult offspring that are slow to take flight, but when and
how they leave has been poorly understood by scientists. Now, new UBC research
on a desert-dwelling African bird is yielding some answers.
Martha Nelson-Flower, a
postdoctoral fellow at UBC, studied the behaviour of wild southern pied
babblers, which live in family groups of up to 14 in the Kalahari Desert in
South Africa. Her findings, published in the Journal of Animal Ecology,
suggest that better prospects elsewhere, as well as family dynamics between
brothers and stepfathers, play a big part in determining when offspring disperse.
