_Geographic range._--Breeds in Alaska south to Prince William

Sound. Winters in North and South America and west in Oceania to

Melanesia. In Micronesia: Mariana Islands--Guam, Rota, Saipan,

Agrihan; Palau Islands--Angaur, Koror; Caroline Islands--Yap,

Ulithi, Truk, Faraulep, Lamatrek, Ponapé, Kusaie; Marshall

Islands--Jaluit, Mille, Arhno, Majuro, Maloelab, Wotze, Likieb,

Ailuk, Bikini.

_Specimens examined._--Total number, 47 (23 males, 20 females, 4

unsexed) as follows: Mariana Islands, USNM--Guam, 13 (May 21-29,

Sept. 19-27, Oct. 10, 23),--Rota, 2 (Oct. 23, 25); AMNH--Guam, 4

(April 23, Aug. 16); Palau Islands, AMNH--exact locality not given,

1 (no date); Caroline Islands, USNM--Ulithi, 3 (Aug. 20, 22);

AMNH--Truk, 1 (June 25),--Ponapé, 1 (Dec. 15),--Kusaie, 19 (Feb.,

Mar., April 1-10); Marshall Islands, USNM--Bikini, 3 (Feb. 26, 28,

April 28).

_Weights._--In 1948 (1948:53) I listed weights of two males from

Guam as 175 (May) and 109 (September); weights of two females from

Guam were 175 and 192 (both in May). These data were obtained by

the NAMRU2 field party.

_Parasites._--Wharton and Hardcastle (1946:296, 316, 318) list the

following chiggers (Acarina) from tattlers taken by NAMRU2

collectors at Guam and Peleliu: _Neoschöngastia bougainvillensis_,

_N. ewingi_, _N. carveri_, and _N. namrui_. Wharton (1946:174,

175) records the chiggers, _Acariscus pluvius_ and _A. anous_,

from tattlers from Guam. It is not certain from which species of

_Heteroscelus_ these chiggers were obtained.

_Remarks._--Records indicate that the American Wandering Tattler is a

regular visitor to eastern Micronesia, and that it only occasionally

reaches the Palau Islands in western Micronesia.

The NAMRU2 field parties found _H. brevipes_ as singles or in small

groups of five or less. They remained apart from other species and

appeared to prefer rocky beaches and coral-reef rocks to the sandy

beaches. At Guam in 1945, the latest spring migrants were taken on May

29. These birds were in nuptial plumage. Birds taken at Bikini by

Morrison on February 26 and April 28, 1946, were in worn, winter

plumage. At Guam, the NAMRU2 observers obtained the first fall migrants

on September 19. These observations in 1945, showed that _H. incanus_

arrived at Guam on its southbound flight fully one month after the first

individuals of _H. brevipes_ began to appear (mid-July). This difference

may partly result from the fact that the distance to the Asiatic

breeding grounds of _H. brevipes_ is not so great as that to the

American breeding grounds of _H. incanus_.

Whether the two tattlers, _H. brevipes_ and _H. incanus_, are distinct

species (allopatric species insofar as breeding ranges are concerned),

or whether they are mere subspecies (geographic races) is open to

question. I failed to find evidences of intergradation in the few

specimens which I examined critically; however, the final answer to the

problem might be obtained by collecting series of birds from breeding

grounds where ranges closely approach each other or overlap (if they

do). Stickney (1943:6, 7) lists the distinctive differences in these two

birds, particularly the character of the nasal groove, and does not

mention having found any evidence of intergradation. Wetmore (in

Townsend and Wetmore, 1919:180) gives evidence that they belong to two

separate species.
