Swallowtail kite migration
From south america in winter
Swallowtail kite nesting behavior
high in tall trees but not at the very top - gives time to build up speed for diving without making 2 egg nest open to great horned owl predators
Habitat of swallowtail kite
wetlands as well as commercial timber land
Pre-migration behavior of ST Kites
Communal roosting
Migration issues for ST kites
Max 4 days of constant flight before death, “dead man’s curve,” leaving Yucatan
Crested caracara
sharpest beak, first on a carcass, vultures follow. breeding pairs do not intrude on each other’s space
number of endemic birds in FL
1 - FL Scrub Jay
Three other scrub jay species
island, california, woodhouse
Male vs female scrub jay
Females have rattling call
Scrub jay young
Altricial, juveniles have brown head and thinner neck but are the same size as adults
Scrub ecosystem
coastal + inland sandy ridges, xeric, nutrient poor soils, pyrogenic vegetation, open structure
Scrub jay breeding behaviors
Cooperative breeding, young individuals help established breeders (0-5) doing everything but mating and incubating
Efforts for conservation of FL scrub jay
Habitat protection and management, education, translocation (not substitute for habitat management but high survival rate)
House sparrow
introduced in 1851 for biological control of caterpillars
