The Sooty Tern is common along 

 the coast of Southern Florida in summer. It probably breeds in Florida, as 

 it does so in large numbers in the Bahama Islands. Eggs usually two, buff 

 white marked with chocolate brown.

 The Bridled Tern is a tropical species which is accidental on our coast. 

 It has once been taken in Florida and probably will be found to occur regu- 

 larly in summer. I found it breeding in the Bahama Islands in June, 1879, 

 in company with the Sooty Terns. The eggs are usually two, cream color 

 or brownish white blotched with chocolate brown.
