FAMILY TYRANNIDAE 587 



Museum, secured in Veraguas by Benson, are male and female taken 

 at Santa Fe, March 25 and 28, 1925, El Villano, near Santiago, 

 August 19, 1924. and Cerro Montuosa (at 650 meters) August 6, 

 1925. J. R. Karr netted and banded one at Chiva Chiva, Canal Zone 

 (December 14. 1968). The most eastern specimen on record at 

 present is a female in the Rothschild collection in New York, taken 

 February 23, 1899, by E. Andre, on the savanna east of Panama 

 City. 



In the British Museum (Natural History) there is one (sex 

 marked 5, but with wing 63.5, probably a male) collected by Arce 

 from Calovevora, Veraguas. Griscom (Bull. Mus. Comp. Zool., vol. 

 78, 1935, p. 354) cites two records from "Veraguas" but I have found 

 only this one. Another (sex not marked) was collected March 25, 

 1863, by Salvin near the old San Pablo Station between Gamboa and 

 Frijoles (now submerged in Gatun Lake). Lawrence listed a male 

 collected by McLeannan and Galbraith on the Atlantic slope near 

 the railroad, without citing the actual locality. The U.S. National 

 Museum collections include a male taken by R. R. Benson at Farfan, 

 Canal Zone, January 27. 1931. 



On March 11, 13, and 16, 1957, I found this species in stands of 

 open forest along the lower Rio Caldera, below Pedasi, Los Santos. 

 The area was one with low undergrowth beneath trees of moderate 

 height. Clumps of the spiny corozo palm stood among rather open 

 shrubs that often were bound with vines. The flycatchers perched 

 quietly and rather stolidly a few meters above the ground, coming 

 near when attracted by squeaking. In their quiet mannerism they 

 suggested Wood Pewees, often resting motionless, only turning the 

 head slightly to look about. On one occasion when swarms of small, 

 dull-colored butterflies hovered over the dead leaves on the ground 

 I found the stomachs of two of these flycatchers crammed with frag- 

 ments of butterfly remains. 



Moore (Condor, vol. 46, 1944, pp. 6-8) described the nest of 

 Leptopogon a. pileatus (the northern race) in Veracruz, as a round 

 ball of "green and dried moss, woven around a fragile framework 

 of very fine roots, plant stems and grasses" with a small entrance 

 hole in one side. The three nests seen were suspended from hanging 

 roots, two of them in dark shadows beneath large rocks. On May 1. 

 1942, one sheltered two small young. A third nest, beneath a huge log 

 over a stream, held three heavily incubated eggs which "were im- 

 maculately white with a slight gloss." One was broken. The other 

 two measured 18.5 X 14.8 and 19.8 X 14.5 mm.
