| − | Phillipine eagle pairs mate for life, and only mate with another when a partner dies. A single egg is laid in a large nest constructed in a treetop, and is incubated for about 60 days. The nesting period can last nearly four months, as both parents take turns feeding the chick, which won't begin to fend for itself until at least its fourth month after leaving the nest.<ref>http://library.thinkquest.org/27257/philippineeagle.html</ref> The eagle has been known to live up to 40 years in captivity.<ref>http://www.philippineeagle.org/index?pageval=thephileagle</ref>
