Breeding Biology and Design of Population Monitoring Methods for Lapland Longspurs
Entry ID: usgsbrdfresc0012

Abstract: The Colville River Delta in northern Alaska
supports large populations of breeding waterfowl,
shorebirds, and loons. The Colville field station
is one of the only programs devoted to monitoring
long-term trends in tundra-breeding birds. Nesting
density and reproductive success of all species
occurring in fixed plots is monitored at this
station. Species of current management interest
include white-fronted geese, spectacled eiders,
oldsquaw, and tundra swans. Shorebirds and loons
are monitored as part of other USGS-Biological
Resources Division studies.

Purpose: Data on variation in nesting density and clutch
size will be used to understand how productivity
varies among habitats and among years, especially
in relation to the timing of spring. Data on
reproductive success in various habitats prior to
oil development will also serve as a baseline
against which post-development estimates can be
