Birders who reside in or visit Florida know that many of the State's avian species, especially the larger ones, can be seen from a moving vehicle, even while traveling on the Interstates. While not an ideal form of birding, it does help to pass the time when road trips are necessary.
Cattle egrets and sandhill cranes are often observed on the open fields and pastures while ospreys, bald eagles and vultures (both turkey and black) frequently soar overhead. Ibis, wood storks, anhingas, roseate spoonbills, egrets and a variety of herons tend to cross your path and swallow-tailed kites may be observed strafing the roadside treetops. Should your drive be close to the sea or large bays, you might also encounter brown pelicans, cormorants, magnificent frigatebirds and a host of gulls and terns.
I suppose it is best to keep your eyes on the road (and, for the record, I officially recommend it) but, as an avid birder for almost fifty years, I know that we reflexively identify any passing, airborne image.
