In Florida, avian species in the families Cardinalidae (northern cardinal, Cardinalis cardinalis), Columbidae (mourning dove, Zenaida macroura), Corvidae (blue jay,
Cyanocitta cristata), and Icteridae (common grackle, Quiscalus quiscula) are frequently exposed to SLEV (14).

Nest predation is another factor potentially affecting warbler numbers; Engels and Sexton (1994) found a negative correlation between an important nest predator in urban environments, the Blue Jay (
Cyanocitta cristata), and Golden-cheeked Warbler breeding density.
