This data package presents raw legacy data collected during 1980 on the Yakutat Forelands of southeast Alaska. The data were collected to identify and understand the occurrence and distribution of birds and mammals in the ocean and wetlands near Yakutat. Migration "sea watches", aerial surveys, and ground plot surveys were conducted in the foreland area of Yakutat in spring (April - May) and fall (August - October) of 1980. The data are presented as PDF files of digitally scanned information as follows: 1) original field data forms describing migration "sea watches" in spring and fall, 2) original field data forms describing aerial survey observations of migratory birds in spring and fall, 3) photos, maps, and notes describing locations of aerial survey observations, 4) original field data of birds observed on ground plots in spring and fall, 5) original field data of habitat classifications for ground plots, 6) original field data of observations of habitat use by migratory birds, and 7) notes on images and maps used in analyses of habitat data.
