Davis 1942 77 Lake Amega, Zoo; deft. San Miguel, El Salvador Feb. 20, 1942. Remains, and it is possible that these birds were resting in the cool shade of the canyon. Feb. 21, 1942 Hunted in dense jungle forest. Shot an El Salvador Attila. These birds sing near the tops of the very tall trees, 60 or 70 feet from the ground, and will sing from one perch for lengthy intervals. The song is rather complex, and very distinctive. When disturbed, they utter a series of very harsh notes, which are in marked contrast to the clear song. They never seem to fly very far when disturbed, but move from one branch to another, or possibly from one tree to another, where sin- ging is resumed. These birds, from what I have seen, are not paired yet. In a very dark, well shaded spot ran across a pair of Pygmy Woodthrushes, of which I took the ♂, the other bird flying at my shot. The birds were working on separate, but adjacent trees. Later in the a.m. I saw across a third, rather near the place where I had seen the pair. This bird may have been the ♀. I could not collect it. Shot a Glaucid Flycatcher perched low in a small shrub. The resemblance between these and a medium-sized Empidonax when perched is striking. These birds are also unpaired, & not singing. Collected a Bent-billed Flycatcher, all of these I have seen thus far are silent and unpaired. The fly- catchers seem to show very definite perching preference. Spade-bills prefer dense undercover, remaining 20 or feet from the forest floor. Glaucid Flycatchers are usually found 5 or 6
