Most Florida scrub-jays breed for the first time when they are between 2 and 4 years of age. Nesting occurs from March to June when 3 to 4 eggs are laid in cup-shaped nests. The nests are constructed in shrubby oaks 3 to 7 feet from the ground. The female incubates the eggs for 17 days until hatching. Both parents and helpers bring food to the nestlings who remain in the nest for 16 to 21 days after hatching.
Predators including raccoons, cats, snakes, blue jays, and crows eat the eggs and hatchlings .
Nest predation is generally higher in suburban areas than in more isolated areas. However, the biggest threat to the scrub-jay is habitat loss and degradation due to the construction of buildings and roads. As development increases, habitats become fragmented and can lead to the isolation of populations or leave individuals without mates. Scrub is frequently converted into agricultural fields, especially citrus groves, and housing developments. In addition, when natural fires are suppressed, trees grow too tall and dense for scrub jays to forage and nest successfully.
