Changing of the Guard: Hairy Woodpeckers Sharing Parental Duties

5-30-16 hairy woodpeckers  215

When their offspring are very young, Hairy Woodpeckers feed them by regurgitation.  As the nestlings mature, the parents bring food back to the nest.  Most species of birds (85%) engage in bi-parental care, where the male and female contribute equally to feeding and guarding their young.  Often the male does more of the food gathering and the female more of the brooding.

In some of these species the male and female both brood as well as gather food.  Hairy Woodpecker parents share these duties equally for the month that their young remain in their cavity nest.  They both brood their young, with males typically getting night duty, and both gather food for their nestlings.  Lawrence Kilham, a New Hampshire MD and ornithologist, found that male Hairy Woodpeckers foraged farther from the nest, made fewer feeding visits, and brought larger prey to nestlings, whereas females remained closer and fed young three to four times as frequently as males.  (Photo: female Hairy Woodpecker arriving with arachnid food, male about to depart.
