Songbird study offers new insights into how malnutrition impairs development and cognition

Slim postpartum pickings for young birds may stunt their brain growth and impede their ability to later remember where they store food. In fact, early deprivation may send adult birds into a downward spiral and thwart their survival, according to new research by Vladimir Pravosudov, PhD, of the University of Nevada, Reno, and Pierre Lavenex, PhD, and Alicja Omanska, PhD, of the University of California, Davis.
They studied the impact of early malnutrition on the western scrub-jay, a long-tailed, blue-feathered songbird. They underfed scrub-jay chicks. Then a year later, when these scrawny chicks grew up, they were worse off as adults than birds who ate better when young–even though the experimental group had caught up by then in weight. The experimental birds had smaller hippocampi with fewer neurons than the control birds and performed worse on spatial-memory tasks that required them to recover seeds they had cached away.
