Black brant Growth Data

Data was collected on the Yukon Kuskokwim Delta, Alaska, USA from 1987-2014. Goslings were web-tagged at hatch, so age in days was able to be calculated at recapture. Goslings were recaptured and weighed at approximately 30 after hatching. Column Headers: MASS is individual gosling's mass in grams at capture at approximately 30 days; AGE is individual gosling's age at recapture; YEAR is the year an individual gosling's mass was recorded; TAGDAY is the Julien date of an individual gosling's web-tagging
