Tule Goose Migration Tracks, 2019 and 2020
Fall migration routes for tule geese in 2019 (five geese) and 2020 (four geese) through arrival at Summer Lake Wildlife Area, Oregon. This area experienced massive wildfires in 2020 which resulted in aberrant migration behavior, increased energetic demands, and increased mortality risk.
