GALLINULA CHLOROPUS GUAMI Hartert 



GaUinula chloropxts giiami Hartert, Nov. Zool., vol. 24, 1917, p. 268. (Guam.) 



Guam Island : Achaiig Bay — i male, i female, June 7, 18. 



Ten specimens from Guam, Saipan, and Tinian in the collection 

 of the United States National Museum have been compared with 

 gallinules from other areas. These birds are similar to G. c. indica 

 Blyth and to C. c. lozanoi Lletget but the upper wing-coverts are 

 darker and near "olivaceous black," and the back, rump, and scapulars 

 are also darker and less richly washed with olivaceous brown, though 

 not as dark as representatives of G. c. orientalis Horsfield from Java. 

 In size, the Mariana birds are similar to the former two races. 



At Guam, gallinules were found in fresh-water marshes and in 

 fallow rice paddies. Weights of the birds are: adult male 291, adult 

 female 256. The male, collected June 7, had enlarged testes. 



GALLINULA CHLOROPUS snbsp. 



Palau Islands: Angaur Island — i unsexed adult, 2 juvenile males, 

 September 21. 



The single unsexed adult appears very distinct when compared with 

 gallinules from adjacent areas. Its coloration is paler, the upper 

 wing-coverts being less olivaceous brown and more slate colored, and 

 the back, rump, and scapulars being less richly washed with olivaceous 

 brown than specimens of G. c. indica, G. c. lozanoi, and G. c. guami. 

 In size it resembles G. c. orientalis with wing 150 and tarsus 46, but it 

 is also much paler than this race. The Handlist of Japanese Birds, 

 3d ed., 1942, p. 221, records G. c. indica from Babelthuap Island, 

 Palau Islands. 



The three birds were taken at fresh-water and brackish-water 

 swamps on Angaur Island. Several birds were also observed at 

 Peleliu Island (pi. 3, fig. 2). One of the juveniles was growing its 

 wing feathers when collected, indicating that the birds must breed 

 in the Palau Islands.

Palau Islands: Angaur Island — i chick, September 21. 

 One chick was caught by Davison at the edge of a fresh-water lake 

 at Angaur Island. An adult was flushed from the same area.
