145. Glaucis hirsuta affinis (Lawrence). Lesser Hairj' Hermit. 



Two males and a female, Gatim, February 5 and May 7, 1911, and 

 April 30, 1911. Iris black, maxilla black, mandible yellow with black 

 tip, feet flesh color. 



A bird of the thick jungle, always well below the top foliage. 



Four nests found April 30 hung on blades of thorny palm leaves 

 fastened with cobweb. May 7, one nest contained two pure white 

 eggs, .35 X .61 and .34 x .62 in. 



146. Phoethornis adolphi saturatus Ridgway. Dusky Hermit. 



Two males, Gatun, April 9, 1911. Iris black, maxilla black, mand- 

 ible bright yellow abruptly black near tip, feet flesh color. 



Frequently seen but always near the same spot, a stretch of jungle 

 just west of Gatun dam. They seldom ^y ov^er twelve inches from the 

 ground, usually under the foliage, darting al^out like bees. They are 

 very noisy, chirping constantly one note at a time and then several 

 rapid notes of varying pitch. This sounds so like several birds that I 

 have more than once crept close and looked long to find a single indi- 

 vidual perched on a leaf stem a few inches from the ground, beating 

 his little tail up and down as though he would break himself in two and 

 chirping away for dear life. Once I saw one leave a leaf stem about 

 eight inches from the ground and hanging on invisible wings revolve 

 around and around as if he were a weight suspended at the end of a 

 thread, first one way and then the other as if winding and unwinding. 

 Then with great energy he flew in a figure eight back and forth over 

 the same path, and the figure was not over eighteen inches long.

147. Phoethornis longirostris cephalus (Bourcier and Mulsant). Nicaraguan Hermit. 



Two males and a female, Gatun, February 12, May 7 and 30, 1911. 

 Iris-black, bill black with base of mandible yellow, feet pink. 



A bird of the thick j ungle. Its nest Avas hung on the underside of a 

 broad leaf at the pendant tip. It was a compact cup of grass stalks 

 wrapped onto the leaf tip with spiders' webs, the nest tapering down 

 below the end of the leaf. The bird sits facing the leaf with his bill 

 pointed straight up against it. The broad point of the leaf arches 

 overhead like a roof. (Jewel.)
