THALASSEUS SANDVICENSIS ACUFLAVIDUS (Cabot) 



Cabot's Tern 



Sterna acuflavida Cabot, Proc. Boston Soc. Nat. Hist., vol. 2, 1847, p. 257 

 (Tancah, Yucatan). 



Several Cabot's terns were seen on May 10 at sea about 15 kilo- 

 meters north of Beata Island, Dominican Republic. 



ANOtJS STOUDUS STOLIDUS (Linnaeus) 



Noddy Tern 

 Sterna stolida Linnaeus, Syst. Nat., ed. 10, vol. 1, 1758, p. 137 (West Indies). 



The noddy tern, known to the native fishermen as bubi, was com- 

 mon about the off-lying rocks opposite Ocrik on the north coast of 

 Beata Island, Dominican Republic, and on May 10 came flying about 

 our sloop in flocks when we were 15 kilometers north of the island. 

 The birds fed entirely at sea and were not observed again, save through 

 binoculars at a far distance, until May 14 when we visited the isolated 

 rocks mentioned in search of sea birds. Colonies of noddies were 

 found nesting on two of these, and two adult females and 10 sets of 

 one egg each were collected. Two eggs were slightly incubated and 

 the others were fresh. On May 16 noddies were noted at sea north 

 to Puerto Caiman, below Enriquillo. 



The eggs v/ere placed on slight piles of vegetation and were scattered 

 at random over the open surface of the rocks, in contrast to the eggs 

 of the bridled terns that nested here also and that were placed more 

 or less under shelter. 



In ground color the 10 eggs obtained vary from dull white to very 

 pale cartridge buff. They are spotted with brown ranging from 

 chocolate and warm sepia to bone brown, which is changed to vary- 

 ing shades of bluish slaty gray where the markings are overlaid by 

 calcareous shell material. The markings vary from fine to bold, in 

 one or two eggs being confluent over certain areas so as to present 

 the appearance of blotches. They are most abundant about the 

 large end of the egg, but are scattered in varying amounts elsewhere, 

 some eggs having few markings while in others they are abundant. 

 Measurements, in millimeters, are as follows: 50.5 by 36.2; 51 by 35.7; 

 51.5 by 36; 51.8 by 34.5; 52.3 by 36.2; 53.1 by 35.2; 53.4 by 36.5; 

 53.9 by 36.7; 54.1 by 35.2; 56.2 by 35.6.
