Migratory strategy drives species-level variation in bird sensitivity to vegetation green-up. Nature Ecology and Evolution. DOI:10.1038/s41559-021-01442-y.


Data used to derive these arrival estimates come from eBird, which should be cited as:

Green-up data were derived from the MCD12Q2 (https://lpdaac.usgs.gov/products/mcd12q2v006/) and MCD12Q1 (https://lpdaac.usgs.gov/products/mcd12q1v006/) data products and should be cited as:
