_Geographic range._--Micronesia: Mariana Islands--Guam.
_Characters._--Adult male: A small flycatcher with head and neck
near "dark delft blue" with a metallic luster; lores and anterior
forehead ashy-gray, more bluish and darker on auriculars and sides
of neck than on lores; back and upper wing-coverts near
"green-blue slate" but darker and with metallic luster less
apparent than on head; rump grayer than back; chin and throat
white; breast light "cinnamon," fading to pale buff and white on
abdomen, sides, and under tail-coverts; tibia smoky-gray, tips of
feathers paler; wings dark brown edged with light bluish-gray;
tail bluish-slate, especially middle rectrices, tips of tail
feathers edged with white; bill and feet black; iris dark brown.
Adult female: Resembles adult female of _M. o. erythrops_, but
crown and neck near "deep Payne's gray," auriculars grayer than
neck; anterior forehead and lores buffy and tinged with cinnamon;
back browner than lores with upper wing-coverts and scapulars edged
with slightly lighter brown; rump resembles crown but grayer;
underparts paler than those of _M. o. erythrops_, especially chin
and throat; tibia more brownish.
Immature male: Resembles adult male, but back more brown and less
blue-green, lacking luster; anterior forehead more rufous;
scapulars, upper wingcoverts, and wings edged with light brown;
underparts variable but generally more buffy than those of adult.
Immature female: Resembles adult female, but more brown and less
blue on head and back; underparts more buffy; base of bill paler.
_Measurements._--Measurements are listed in table 42.
_Weights._--The author (1948:68) records the weights of five adult
males as 10.5-12.5 (11.9), and those of two adult females as 11.4
and 12.0 grams.
_Specimens examined._--Total number, 64 (33 males, 22 females, 9
unsexed), as follows: Mariana Islands, USNM--Guam, 26 (Jan. 21,
March 16, May 21, 29, 30, June 1, 3, 14, 24, 26, July 10, 12, 13,
20, 23, Aug. 30); AMNH--Guam, 38 (Jan., Feb., March, July, Aug.).
_Nesting._--The writer (1948:68) records a nest containing one egg
found by Muennink at Guam near Mt. Santa Rosa on May 7, 1945. The
nest was in a bamboo stump approximately six feet from the ground.
The egg hatched on about May 21. Seale (1901:50) reports on a nest
and egg taken in the period from May to July. The NAMRU2 party
obtained a female on March 15 with an enlarged gonad. Strophlet
(1946:539) observed a pair of broadbills building a nest on
September 20, 1945; it was completed on October 4 and was
approximately seven feet above the ground. Hartert (1898:33)
reports on a nest taken at Guam on February 14, 1895.
_Molt._--As shown by the specimens examined, molt begins in June
or July.
_Food habits._--The stomach of a bird obtained on January 21,
1945, contained one unidentified bug (Hemiptera) and several parts
of other insects.
_Remarks._--The Micronesia Broadbill at Guam is not a common bird, and
like its relative _Rhipidura rufifrons_ is an inhabitant of forested
areas, especially those containing brushy undercover. It is an active
bird, although less conspicuous than _Rhipidura_. The birds were found
as singles or in pairs. The pair of birds which had a nest at the west
base of Mount Santa Rosa in May, 1945, allowed the observers to approach
closely to them. The birds are easily attracted by squeaking sounds.
There is considerable variation in the amount of cinnamon coloring on
the breasts of adult birds.
The Micronesian Broadbill at Guam was first discovered by Quoy and
Gaimard, who called it "Moucherolle à gorge rouge." Kittlitz (1836:304)
evidently records two species of flycatchers from Guam, which he calls
_Muscicapa_. I judge these birds to be _Myiagra_ and _Rhipidura_. It was
not until 1881 that Oustalet recognized this bird to be new. The first
large series of specimens was obtained by Marche for the Paris Museum
and was reported on by Oustalet (1895:194). Marche collected 12 skins in
August and September, 1887, and 4 additional skins in February, 1889.
