. Bird lore . MAN-O-WAR BIRDS The Tortugas Tern Colony 83 staccato laugh than anj^thing else to which it may be compared; also afew low and musical tones, used when a pair are communicating witheach other, as when the male has returned from a fishing expedition.Their warning note is a high and shrill e-e-e—e. Normally, in the Tortugas, there are, on an average, a score of Man-o-War Hawks {Fregata aquila), but when the Terns arrive their num-ber is increased to over three hundred.
