Black Brant (Branta bernicla nigricans) Radio Detection and Migration Timing Alaska to Mexico This is a child item of the USGS Data Release: https://doi.org/10.5066/F7T43R88 This data package provides data from Pacific Black Brant (Branta bernicla nigricans) 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.
