This data package contains one table with nest initiation and end dates and clutch sizes from Black Brant (Branta bernicla nigricans) at two breeding colonies in Alaska. Data include nesting period determined by either nest visits or light-level data recorded by geolocators attached tarsal bands.

This data package includes 2 child items with data from Pacific Black Brant (Branta bernicla nigricans) during winter and migration periods. Child Item 1: "Body mass, Morphological Measurements, Flock Counts, and Age-Ratios from Black Brant Overwintering in Three Lagoons Along the Baja California Peninsula, Mexico". The data include: (1) body mass and morphological measurements from sport hunter harvested brant, and (2) census counts of brant in Bahia de San Quintin, (3) counts for flock age ratio determination, and (4) behavior. Child Item 2: "Black Brant (Branta bernicla nigricans) Radio Detection and Migration Timing Alaska to Mexico". Data from brant tagged with VHF radio transmitters in July 1999 on the Yukon Kuskokwim Delta, Alaska and detected in the following two years during their annual migration. Data include: 1) one table with attributes of the tagged brant, 2) one table with estimated dates of migration events, and 3) seven tables of detection data from radio tracking scans at coastal sites between Alaska and Mexico.

This data release includes 2 child items with tracking data for Black Brant, a goose species that breeds in coastal areas of Alaska, northwestern Canada, and northeastern Russia and winters along coastal areas of North America from western Alaska to Mexico. Child Item 1: "Light-Level Geolocator Tracking Data for Black Brant (Branta bernicla nigricans)" -- Tracking data collected from light-level geolocator attached Black Brant at breeding areas in Alaska, 2003-2007. Child Item 2: "VHF Triangulation Tracking Data for Black Brant (Branta bernicla nigricans) in Waters Adjacent to Izembek National Wildlife Refuge, Alaska" -- Tracking data collected from triangulation tracking of VHF transmitters at Izembek National Wildlife Refuge, Alaska, during fall 1987-1990.

Child Item 1: "Light-Level Geolocator Tracking Data for Black Brant (Branta bernicla nigricans)" -- Tracking data collected from light-level geolocator attached Black Brant at breeding areas in Alaska, 2011-2014.

This data package contains estimated location data from triangulation tracking of VHF transmitters on 93 Black Brant at Izembek National Wildlife Refuge, Alaska, during fall 1987-1990. The transmitters were attached to second year and older Brant on breeding colonies in Alaska, northwestern Canada, and northeastern Russia. The data include: a deployment attributes file with details of each brant at the time of capture, the raw bearing data, and location estimates from triangulation.
