Il6 BIRDS OF THE REPUBLIC OF PANAMA PART 4 



massif, and is often seen or heard in this area along roadside thickets 

 and hedgerows separating open fields, at a distance from surviving for- 

 est. In this highland region, Eisenmann found it the commonest wren, 

 having adjusted to clearing and cultivation, and calling attention to itself 

 by persistent singing, even through it skulks in vegetation, generally 

 from a few centimeters to 1 or 1.3 m from the ground. Notably abun- 

 dant in the Cerro Punta area, now largely devoted to vegetable crops, it 

 frequents the shrubbery at field boundaries (as well as forest borders 

 and interiors) . In this region it occurs below El Volcan at least down 

 to 1 1 10 m along the highway, and about the Volcan lakes. It occurs also 

 at the summit of the trail to Boquete, and seems to be everywhere in the 

 outskirts of Boquete, even in the rather scantily vegetated El Salto. On 

 Cerro Campana, where sympatric with H. leucosticta, it is much less 

 numerous than that species and is confined to humid forest about the 

 summit. 



This species less frequently carries its relatively longer tail cocked 

 up than does the White-breasted Wood- Wren, and its rufescent lower 

 underparts are conspicuous in the field. 



The song, although musical and loud, is not of as rich or mellow a 

 quality as that of its congener, but usually consists of many more 

 syllables, and lasts longer before it is repeated. One bird seen by Eisen- 

 mann on September 20, 1958, gave three different songs, all loud, 

 rollicking whistles of similar timbre. He noted the following songs : too- 

 tee-ooweet, weetee, weetoo, also weeloo-weechee, too-loo-wheew, and 

 cheerooeechee-cheeweecheerooweechee, with variants of each, and all 

 repeated over and over. On September 21, he saw a bird give a very 

 different, sweet, soft, almost formless, warbled song — a subsong, per- 

 haps by an immature individual. A rattling chatter tit-tit-t-t-t-treet, 

 sometimes shortened to tit-teerrrt was often heard by Eisenmann (tape 

 recorded by E. S. Morton, Cornell Laboratory of Ornithology) . 



H. Loftin reports that 1 banded at Cerro Punta March 26, 1967, was 

 recaptured March 27, and April 28, 1968, and March 1, 1970.
