Growth and recovery of the bald eagle population in Oklahoma

Abstract

We conducted surveys twice annually from 1990–2003 to determine the occupancy and reproductive success of known and newly reported bald eagle (Haliaeetus leucocephalus) nests in Oklahoma. During the study period, the number of nesting pairs of eagles increased from 0 to 41, and the number of young fledged per nest has remained between 1 and 2. The population and productivity level of bald eagles appear sufficient to declassify the species from its current listing as a federally threatened and state endangered species in Oklahoma.
