1S90.] Cherie, Nesti)ig Habits of Costa Rican Birds. 2 7*7 



eggs measure respectively .87 X -62, and .90 X -63 inch. They 

 are creamy-white, thickly speckled, chiefly about the larger end, 

 with irregular spots varying in color from liver brown to orange 

 rufous. On finding the nest I waited a few minutes. The female 

 flew quickly to a tree near by, but gave no note to indicate her 

 presence. 



On this same date I took the first fully fledged young. It dif- 

 fered from the adult only in the absence of the concealed crown 

 patch and in much softer plumage. 



I took a fourth nest June 11. It w^as placed about twelve feet 

 from the ground in the upright forks of a small tree that stood 

 alone in a large field. It is a little unusual in shape, being oval 

 in form, while ordinarily they are almost round. The measure- 

 ments inside are 2.3S by 1.3S, by 1.12 inches deep; outside 3.50 

 by 3.00, by 1.75 inches deep. It is beautifully covered with lich- 

 ens, and is lined first with a few horse-hairs, and then completely 

 with white chicken feathers. The eggs measure .S7 X -65 and 

 .SS X .66 inch, and in color are like those already described. 



The last nest I took was on June 14. With this the birds were 

 as unexpectedly slow in the use of their nest as the owners of the 

 nest of May 5 were quick. I found it just completed, but without 

 eggs, on June 7. On June 9 it was still empty. On June 14 it 

 contained two fresh eggs. The nest was about seven feet from the 

 ground in a tree that grew at an angle of about 45 with the 

 ground ; at the first branches there was formed a broad, flat space, 

 and there the nest was placed. None of the materials of construc- 

 tion went around the branch to bind it there, but it w r as attached 

 quite firmly with lichens and spider webs. It measures inside 

 2.25 inches in diameter by [.3S inches deep ; outside 3.50 X 3-oo 

 inches by 1.50 deep. It is lined first with horse-hairs and then 

 with soft light-colored feathers. The eggs measure .84 X -6 "J and 

 .85 X -66 inch, and are marked like the preceding. While I 

 was at the nest both birds remained close at hand, flying restlessly 

 back and forth. Whenever they alighted they stood very erect 

 with the crest fully expanded. They seldom uttered a note.
