512 BIRDS OF THE REPUBLIC OF PANAMA — PART 3 



Kennard collected one February 28, 1926, and Austin Smith one 

 April 24, 1927. One in the British Museum marked Calovevora, 

 Veraguas, was taken by Arce in 1869. On the upper Rio Indio I 

 found one in heavy forest near El Uracillo, on the northern slope of 

 Code, on March 2, 1952. In the northern Canal Zone the bird has 

 been recorded on Barro Colorado Island and elsewhere. 



Hasso von Wedel secured specimens in eastern San Bias at Perme, 

 Ranchon, and Puerto Obaldia. At the latter locality I collected one as 

 it moved quietly in a leafy tree top on February 17, 1963. I have 

 found them common only in eastern Darien. Near Jaque on the coast 

 I saw them in pairs in thickets of guava along the Rio Jaque, and also 

 in tall, swampy forest. In 1959 we found them in pairs in late Febru- 

 ary and early March in the forest along the Rio Tuira at the mouth 

 of the Rio Paya. And later on the Rio Pucro farther inland in 1964 

 I saw them alone, and once in company with a moving band of small 

 birds in the forest. 



On Barro Colorado, April 6, 1948, I saw one carrying nesting 

 material, but did not locate the site. I have seen no record in literature 

 of the form of the nest or of the eggs.
