What ecological principles apply to the following scenario? Known as the "Hawaiian woodpecker," the akiapola' au (aki-a-pul-a-ow) is found only in montane mesic old-growth koa/ohi forests, and only on the Big Island (Hawail) It has a distinctive beak that is like a multiple-use tool. The short straight lower mandible is used to peck holes in the wood and the long curved upper le is used to probe for insects and larvae. Males have larger beaks than females and feed on the trunks of trees. Females feed higher on branches and twigs. Akiapola au are thought to have the lowest reproduction rate for a small bird -only one chick per year, which is cared for by the parents for 6 months or more. The decline in their numbers appears to correspond with the introduction of rats, cats, and logging on the island.
