Common Tern Sterna hirundo ``A vibrant, purring tearrr'' (Chapman) 17kB Tearrr 13kB Long Island, August 1997.
Courting vocalizations. The courtship scene for Common Terns is somewhere
between the Debutante Cotillion and the Roller Derby. In this instance,
about 100 Terns are standing on a steadily shrinking sand bar. At any one time
five or six are undertaking ritual bathing in the adjacent shallows.
At any one time three or four couples are engaged in the "stand on my back"
phase of courtship. A few fish are served, but it is nothing like the
inflexible protocol of the Little Terns (see below). The two main
sounds are
tearr, tearr, tearr, ...
(males?) and a rapid
yip, yip, yip, ...
(females?). Here is how they sound
