Spring Watch USA premiered on Animal Planet on April 28, 2007. Spring Watch USA is a four-week, as-it-happens, multi-media, nationwide event. Filmed just prior to broadcast, this miniseries is a celebration of the arrival and beauty of spring across the nation. Hosted by Jeff Corwin and Vanessa Garnick, viewers learn about the amazing mammals, birds and insects that herald the arrival of spring. From their Spring Watch USA headquarters on Kiawah Island, located off the coast of South Carolina near Charleston, Jeff and Vanessa give viewers a backstage pass to spring from the animals' point of view. With cameras positioned in nests, caves and other habitats, Jeff and Vanessa track such inhabitants of Kiawah Island as bobcats, red-tailed hawks, alligators, bluebirds and screeching owls. Corwin and Garnick are joined by Animal Planet correspondents Philippe Cousteau and David Mizejewski, who also take cameras along as they report on animal activities from the rest of the country. Cousteau covers sea otters, sea lions and gray whales in California, from Sausalito to Monterey to the Channel Islands. Meanwhile, Mizejewski checks in on the great horned owl and the beaver in Georgia, flying squirrels in Northern Virginia and black bears in Upstate New York.
