The golden-crowned sparrow (GCSP) migrates along the Pacific flyway, wintering in California.

Autumn Iverson is a wildlife ecologist and Ph.D. student in the Ecology program at UC Davis. She studies wildlife movement ecology, behavioral plasticity, and the impacts of environmental change.

Migration is one of the least understood phases of the life-cycle of these birds. During the winter of 2019, Autumn will put GPS tags on 10 birds in California, as part of a larger tagging project. The next year, she will go back to the same location to recapture the birds and collect the tags.
