There is only one record of a Magnificent Frigatebird in Ontario. October 16, 1949 at Port Rowan.
Frigatebirds are residents of the tropics but, unusual for seabirds, their feathers are not waterproof. They never go into the water but “pirate” their food from other birds or catch fish by skimming along the surface. The bill looks like a fish hook.
Here are many photos of these “magnificent” creatures in the sky.
