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.
Perhaps the strangest nests of all are those built by the species of Swiftlet in the genus Collocalia. They nest in caves and build their nests of saliva.

To make them even more amazing, these Swiflets often nest in pitch dark caves.ustralasian Bowerbirds are not the only birds to build structures that are not ever destined to be nests. Others include the Tooth-billed Cat Bird (Scenopoeetes dentirostris), also from Australia, and Jackson's Whydah (Euplectes jacksoni) from Kenya and Tanzania.
