This data package supports raw legacy data collected during 1980 on the Yakutat Forelands of Alaska. The data were collected to support a short-term study of waterbird migration patterns and habitat use during spring (April - May) and fall (August - October). The primary objectives of the study included: 1) determine the timing and rates of migration by waterbirds; 2) correlate observed patterns of migration with weather; 3) determine the use of estuarine and riverine systems by waterbirds during migration; 4) determine the use of wetlands and deep-water habitats by migrant waterfowl and shorebirds.

About the Legacy Data

In spring and fall of 1980, biologists with the U.S. Fish and Wildlife Service Office of Biological Services- Coastal Ecosystems (precursor to USFWS Alaska Region departments and ultimately the Ecosystems Office at the USGS Alaska Science Center) collected observational data on birds and marine and terrestrial mammals occurring within the Yakutat Forelands of Alaska. Primary results were summarized in Petersen et al. (1981; see 'Related Reports and Publications').

This U.S. Geological Survey Data Release is a collection of original field data, maps, notes, and infrared photographs. All documents and photographs have been digitally scanned in PDF format and are archived along with original physical copies at the USGS Alaska Science Center.

Data Constraints

Observational raw data, notes, maps, and infrared photographs are available for download in PDF format upon request by contacting ascweb@usgs.gov. All PDF documents were checked for accuracy and completeness prior to retirement by the principal investigator. Finally, all PDF documents are provided “as is” and do not follow 508 compliance standards.

Please note: All bird species checklists have been submitted to the eBird database hosted by the Cornell Lab of Ornithology (ebird.org). Checklists are also available as a data download from USGS Alaska Science Center under the :Southeast” region (Bird Species Checklists from USGS Alaska Science Center Field Camps).
