  1. *Last fix on October 16, assuming overwintering site but could potentially still be on migration
  2. **Mean (± Standard Error) but not including length or speed for units with less than 10 fixes
  3. Summary of GPS tags attached to Gray Catbirds in the South Okanagan Valley, British Columbia, Canada, and in the Bitterroot River Valley, Montana, USA with an emphasis on migration. Year is year GPS tag deployed. The fall depart date represents the last fix at the breeding site and the arrival date represents the first fix at the overwintering site. The spring depart date represents the last fix at the overwintering site and the arrival date represents the first fix back at the breeding site. Locations (Loc.) are abbreviated as Nuevo Leon (NLE), San Luis Potosi (SLP), Tamaulipas (TAM), Veracruz (VER), Hidalgo (HID), Puebla (PUE), and Texas (TX). Dashes indicate missing data: fall depart date is unclear from three Bitterroot River Valley catbirds due to first fixes occurring mid-migration; lack of spring migration data is due to premature battery exhaustion
