1 Project partners include the Gulf Coast Bird Observatory at Smith Point and Audubon of Florida at Curry Hammock.
2 Data provided by project partner Pronatura Veracruz; Hawk Mountain Sanctuary is also a partner.
3 Due to high abundance of local birds and the difficulty of obtaining reliable and consistent counts of migrants, we no longer tally Turkey Vultures in the Grand Canyon.
4 Dashes indicate that the species has never occurred at the site, whereas zeros mean that the species does occur at the site but was not seen in the current year.
