NO. I AVIFAUNA OF PANAMA — WETMORE II 



V. ADDITIONS TO THE RECORDED LIST OF BIRDS FROM THE 

 REPUBLIC OF PANAMA 



Salmon's Tiger-Bittern, Tigrisoma sahnoni Sclater and Salvin : 

 This species, described from Medellin in the Province of Antioquia, 

 northwestern Colombia, with a recorded range east to Venezuela and 

 south through Ecuador and Peru to western Bolivia, ranges also 

 along the Caribbean slope of the Isthmus of Panama. It was first 

 noticed for this area on February 29, 1952, when I collected an adult 

 male on the Rio Uracillo. near the town of that name in the foothills 

 of the Caribbean slope of Code. I secured another, an immature 

 bird, near the Peluca Hydrographic Station on the Rio Boqueron, 

 Province of Colon, on February 21, 1961, and have a third, shot on 

 the Rio Changena, Bocas del Toro, September 9, 1961. This species 

 differs from the banded tiger-bittern Tigrisoma lineatinn (Boddaert) 

 structurally in the form of the bill, which is shorter and also heavier, 

 less attenuate at the tip. The adult sahnoni is definitely blacker, but 

 the immature differs only in being more extensively white on the 

 lower surface. With the presence of the species known T have found 

 several immature birds in other collections taken earlier in Darien 

 and the eastern Comarca de San Bias, but wrongly identified as 

 Tigrisoma lineatum. 

 Slender-billed Kite, Hclicolcstcs haniatus (Temminck) : 



The slender-billed kite is reported for Colombia on the basis of a 

 record by Salmon from the Rio Ite, near Remedies in Antioquia, 

 and is known from scattered localities from eastern Peru to Vene- 

 zuela (Caicara), Surinam, and the lower Amazon. In Darien, on 

 February 24, 1959, as I landed from a piragua at the mouth of a 

 tiny stream that enters the Rio Tuira a short distance above where 

 the Rio Pa3'a joins this larger river, I was interested to note shells 

 of an apple snail scattered along the sandy shore, and immediately 

 saw one of these kites perched over a shaded pool inside the forest 

 border. The bird was a female. Later I received another skin from 

 the Gorgas Memorial Laboratory, taken near the same point in the 

 previous year. These are the first reports of this little-known species 

 beyond South America. 



Guacharo, Steatornis caripensis Humboldt: 



On the night of March 19, 1959, Bernard Feinstein, assistant to 

 Dr. Charles O. Handley, Jr., captured a female of this species in a 

 mist net set for bats at an elevation of 975 meters near the old 

 Tacarcuna village site on Cerro Tacarcuna, Darien. The guacharo
