This data release contains observational data from a breeding bird inventory using standardized point counts conducted during May-June 2005 in Kenai Fjords National Park (KEFJ), Alaska. It also includes a single survey conducted for owls on the night of 30 April 2005. Data tables include 1) survey route details, 2) survey point details, 3) survey habitat details at survey points, 4) bird detection distance and behavior, 5) bird checklists along survey routes and any evidence of breeding behavior, and 6) bird taxonomy. Although the survey design was optimized for diurnal landbirds, observers recorded all species of birds detected during and between point counts along survey routes. Data were also recorded systematically for a single mammal (red squirrel, Tamiasciurus hudsonicus) during the surveys.
