64 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 134 
MEGARYNCHUS PITANGUA MEXICANUM (Lafresnaye): Boat-billed 
Flycatcher, Pico Canoa 
Scaphorhynchus mexicanus LAFRESNAYE, Rev. Mag. Zool. (Paris), ser. 2, vol. 3, 
October 1851, p. 473. (México.) 
One was observed on Isla Rancheria on February 4. Countrymen 
usually include this species under the all-inclusive name of pechi- 
amarillo. 
MYIARCHUS CRINITUS BOREUS Bangs: Great Crested Flycatcher, 
Pechi-amarillo de Paso 
Myiarchus crinitus boreus Bancs, Auk, vol. 15, No. 2, April 1808, p. 179. 
(Scituate, Mass.) 
A male taken on the Punta Damas trail January 19 was the only 
one recorded. In Panama, attention is drawn to this bird by its clear 
call note, and when seen it is readily distinguished from its close 
relatives by the cinnamon-brown tail. 
MYIARCHUS FEROX PANAMENSIS Lawrence: Short-crested Flycatcher, 
Pechi-amarillo Comin 
Myiarchus Panamensis LAWRENCE, Ann. Lyc. Nat. Hist. New York, vol. 7, 
May 1860, p. 284. (Atlantic slope of Canal Zone on the Panama Railroad.) 
This was the most common species of the flycatcher family, found 
in the crown of the high forest, in brush back of the beaches, and in 
the wooded swamps near the river mouths. The birds move about 
deliberately, watching for insects, and also come to berry-bearing 
trees. Though they are active in seizing prey in the air, they regularly 
search for food, rather than rest in one spot waiting for insects to 
pass. I saw one fly out at a butterfly which, however, it missed. The 
call note is a high-pitched whee-ee-ee, a sound with little carrying 
power. Two were taken on Isla Rancheria February 4. 
The specimens obtained on Coiba Island resemble those from 
Veraguas and Chiriqui in being slightly darker, more grayish above, 
than typical specimens from the Province of Panama eastward into 
Colombia, and thus show some approach to the grayish Myiarchus 
ferox actiosus Ridgway of southwestern Costa Rica. All the Pana- 
manian birds, including those of Coiba, are much brighter yellow on 
the lower breast and abdomen and darker gray on chest and foreneck 
than actiosus.
