The Laysan finch (Telespiza cantans) is endemic to Laysan Island in the Northwest Hawaiian Island. (See Laysan duck entry for a description of island ecology and management history). The population has fluctuated significantly since censusing began in 1966 [1, 2], but shows a weakly increasing trend since 1967. The population was estimated at 7,779 in 1967 and 9,393 in 2004 . It reached highs of 20,802 in 1976 and 18,274 in 1984, and lows of 6,188 in 1978 and 5,201 in 1988.
A population of 108 birds was introduced to the four islets of Pearl and Hermes Atoll in 1967 [1, 2]. In 2005, 707 finches were present . This population has also fluctuated significantly, with three of the islet subpopulations dying out at least once. Although the population has a positive population trend, it is unstable and will always remain small due to the carrying capacity of the islets.
