1. Frigate warships were built for extreme speed. Whether powered by sails long ago or modern engines today, frigates are war vessels designed to be faster and more nimble than heavier, bulkier battleships.

2. Old sailing frigates were "the eyes of the fleet." During war, massive battleships were too slow to scout ahead. Fast sailing frigates sped across the ocean to scout out enemy fleets and send back messages.

3. Modern navy frigates hunt submarines. Today's navy frigates are packed with high-tech sonar systems and helicopters used specifically to search for and track hidden submarines underwater.

4. "Old Ironsides" was a famous US frigate. The USS Constitution is an American frigate built in 1797. During a war battle, enemy cannonballs bounced right off its thick oak hull, earning it the famous nickname "Old Ironsides"!

5. Male frigatebirds inflate bright red balloon throats! Male frigatebirds have a special skin pouch under their beak called a gular sac. To attract a mate, they blow it up like a giant red balloon!

6. Frigatebirds are real-life "pirates" of the sky. Frigatebirds often steal food right out of other birds' beaks! They chase down gannets or boobies in mid-air until the other bird drops its fish, then catch it mid-fall.

7. Frigatebirds can stay airborne for weeks without landing! These amazing birds can sleep while gliding on wind currents and stay flying over the ocean for over a month at a time without ever touching ground.
