A large, lightly built seabird with brownish-black plumage, long narrow wings, and a deeply forked tail, the Magnificent Frigatebird can be seen soaring above the bay and gulf. The male has a striking red gular sac which it inflates to attract a mate.
Kristine Rivers offers this:
“Frigatebirds are amazing aerialists, staying on the wing for weeks at a time, rarely needing to flap and steering with their tails. Although they are water birds, their feathers aren’t waterproof, so they are unable to land on or dive into water. They forage by skimming over the surface of the water and using their long, hooked bills to capture fish and other prey. However, they are better known for their habit of chasing and harassing other birds to steal food from them in midair, even shaking them upside down to force them to release their prey. This pirating behavior caused sailors to give the species the nickname “Man’o’war bird”.”
“Look for them soaring overhead on the West End, perched on pilings near San Luis Pass, and following the ferries on the East End. No matter where you see one, be prepared for an awe-inspiring experience.”
