Sex, length, total mass, fat mass, and specimen condition data for 248 Burmese pythons (Python bivittatus) collected in the Florida Everglades

These data were collected from Burmese pythons removed from the Florida everglades as part of invasive-species management. After euthanasia, we sexed (male or female) and measured the snout-vent length (SVL; cm) and total body mass (g) for each python. We also measured total fat mass (g) by removing all visible fat bodies from the coelomic cavity and weighing this mass. For a subset of specimens, we recorded whether the pythons were put on ice after euthanasia and measured within 24 hours ('fresh') or whether the pythons were frozen after euthanasia, thawed, and then measured ('frozen'). These data were used to validate several body condition indices in Burmese pythons.

Migrating Bird Survey Data Along the San Pedro River and its Tributaries, Southeastern Arizona, 1989-1994

Data files in this data series represent migrating bird count and habitat information collected during 1989, 1991, 1993, and 1994 field seasons at 13 riparian sites along the San Pedro River and its tributaries in southeastern Arizona, USA. At each site observations were made at up to 20 points, separated by 100 m arrayed along the riparian zone. Observation periods started at 20 minutes after sunrise, lasted for 7 minutes at each point and were completed within 4 hours. Bird detection and species identification were based on visual sighting, song, and call. Recorded observations were the number of individuals of each detected species detected using each detection method at each point and site within specified distance...

Data measuring avian influenza infection, mercury concentration, and body condition in wild waterfowl

These data represent mercury contamination, influenza infection, and body condition in 11 species of dabbling and diving ducks in the Pacific Flyway. These data support a USGS lead scientific publication.
