This noddy was one of the most frequently observed oceanic birds 

 in Micronesia. At Ulithi Atoll service personnel reported a large 

 nesting colony in May, June, and July at Potangeras and at a smaller 

 island nearby. Nests were observed in trees and on the ground. One 

 nest was found by our party at Bulubul Island on August 21. A 

 single egg, in an advanced stage of incubation, was collected from 

 the nest, which consisted of a few rough twigs in a shallow depres- 

 sion in the sand above the high-tide mark. The egg is: shape ovate, 

 gloss slight, shell smooth, color white with small irregular spots of 

 the two colors "pale drab-gray" and "pale smoke gray" (the latter 

 predominating), concentrated at the large end, size 36.6 by 50.1. At 

 Truk, McElroy found noddy terns nesting on a high cliff and in 

 adjacent coconut trees at Moen Island in December. 



Weights of birds taken at Guam and Rota are: 4 adult males 187- 

 204 (197), and 3 adult females 177-203 (189). Measurements of 

 10 adult males are: wing 275-291 (283), tail 159-187 (168), exposed 

 culmen 39.8-43.5 (41.4) ; of 4 adult females, 266-283 (274), 154- 

 178 (165), 38.7-40.0 (39.3). Stomachs of birds from Ulithi and

 had enlarged testes.
