BIRDS OF ARGENTINA, PARAGUAY, URUGUAY, AND CHILE 225 



Colaptes J). ]?itin.s was encountered near Concon, Chile, in small 

 numbers. Three of these birds frequented a small valley with slopes 

 grown with low bushes studded with occasional trees along a water- 

 course, where they fed on the ground among the bushes in small 

 openings grown with grass. In spite of this cover they were so wary 

 that it was difficult to approach them, as at the slightest alarm they 

 rose and traveled away with stronglj-- bounding flight that displayed 

 alternately the white rump and the yellow undersurf ace of the wings. 

 Their call was a high-pitched double note, flickerlike in nature, but 

 of different character than the species encountered in Argentina. 

 Like other flickers, I found that they decoyed readily to a " squeak " 

 when they had no cause to suspect danger, a trait that brought two 

 within range and added them to my collection. 



A specimen secured on April 28, 1921 (probably a male), had the 

 bill dark neutral gray, iris chalcedony yellow, and tarsus and toes 

 deep olive gray.

Two skins preserved from the vicinity of Puerto Pinasco, Para- 

 guay, exhibit the characters assigned to the subspecies hehnL A 

 male differs from specimens from eastern Brazil in larger size, re- 

 striction of white on the tips of the lateral rectrices, and more 

 greenish cast to head and breast. The female is larger in size. The 

 white breastband appears wider in both sexes than in the typical 

 form. The male from Puerto Pinasco measures: Wing, 128; tail, 

 124; exposed culmen, 16.5; tarsus, 14 mm.; the female, wing. 120; 

 tail, 120; exposed culmen, 15.4; tarsus, 13.6 mm. 



On September 1, 1920, a female was secured in heav_y timber on 

 a low^ hill at Kilometer 25, west of Puerto Pinasco, Paraguay. The 

 bird flew from some unseen perch to alight as easily as a jay on an 

 open limb, 3 meters from the ground. When it observed me the crest 

 feathers were slowly raised. On September 21 tAvo were taken in 

 the border of somewhat open forest, near Kilometer 80. The call 

 note of this species is a fairly loud regular coo coo coo varied to 

 coh coh coh coh coh. The flight is direct and darting, and on the 

 wing the birds suggest cuckoos in manner and actions. The body 

 in this species exhales the same strong odor found in cuckoos, par- 

 ticularly in the Crotophaginae. 



An adult male, when fresh, had the bill court gray; lower man- 

 dible washed with light celandine green; margin of eyelids yellow 

 ocher; iris carob brown; toes storm gray, with the scales outlined 

 in whitish. In an adult female the bill was light celandine green;
