NO. 15 BIRDS OF THE PACIFIC WAR AREA BAKER 67 



Warblers were found in jungle areas and in the new vegetation 

 which was covering the battle-torn parts of Peleliu. This species 

 occurred in the same environment as the large white-eye, Rukia 

 palauensis, and the similarity between these two forms in the field is 

 striking. Stomachs contained insects. 



ACROCEPHALUS LUSCINIA LUSCINIA (Quoy and Gaimard) 



Thryothorus luscinius Quoy and Gaimard, Voy. Astrolabe, Zool., vol. i, 1830, 

 p. 202, pi. 5, fig. 2. (Guam.) 



Guam Island : Agafia Spring — 2 males, i female, June 2 ; Piti — 

 I male, June 13; Agat — i male, August 30. 



At Guam, reed warblers were found in association with the ex- 

 tensive cane growths in fresh-water and brackish-water marshes. 

 Birds appeared fairly numerous in some of these areas; their songs 

 could be heard, but it was difficult to approach them. The birds 

 seemed shy and hopped about in the cane usually close to the ground. 

 Fire appears to be a hazard to the reed warbler. During very dry 

 periods, its habitat might be easily destroyed by fire. 



Weights of three adult males from Guam are 29-35 (33), and of 

 one adult female 2"/. This bird was not found at Rota by our collecting 

 party. 



ACROCEPHALUS LUSCINIA SYRINX (Kittlitz) 



Sylvia Syrinx Kittlitz, Mem. Acad. Imp. Sci. St. Petersbourg, vol. 2, 1835, 

 p. 6, pi. 8. (Lugunor and "Ulcei," Caroline Islands.) 



McElroy found reed warblers in cane swamps at Moen, Udot, and 

 Dublon islands in the Truk Atoll. He saw birds carrying nest 

 materials. Two adults examined in December had enlarged gonads. 

 Specimens were lost in shipment.

Fantails were found in forested areas where there was a thick under- 

 cover of vines and shrubs. Birds collected in May and June were in 

 molt. Weights of nine males are 8.0-10.0 (9.0), of three females 

 7-3-9.6 (8.8).
