Scientists aren't sure how long giant pandas live in the wild, but they are sure it's shorter than lifespans in zoos. Chinese scientists have reported zoo pandas as old as 35. The National Zoo's Hsing-Hsing died at age 28 in 1999.
Today, Montezuma National Wildlife Refuge boasts six active bald eagle nests. The infamous trio's nest can be viewed from Armitage Road, located off of NY State Route 89. The trio has nested on the refuge since 1987; the two males are from a reintroduction program conducted in the late 1970s.
Pairs may remain together all year, joining small flocks with other titmice in winter. Flocks break up in late winter, and pairs establish nesting territories. Male feeds female often from courtship stage until after eggs hatch. Breeding pair may have a helper, one of their offspring from the previous year. Nest site is in hole in tree, either natural cavity or old woodpecker hole; averages about 35' above the ground, ranging from 3' to 90' up. Unlike the chickadees, apparently does not excavate its own nest hole. Will also use nest boxes.
