lands of both the Atlantic and Pacific slopes, up to not more than 

 2,000 feet above sea-level. They are denizens of the heavy forests, 

 which they never leave, frequenting the banks of sluggish creeks, 

 springs, and boggy spots. They are almost always to be seen in pairs 

 and are not very shy, but with caution can be approached quite closely. 

 Their usual station is on the ground, but when flushed they sometimes 

 alight in the trees at no great height. I was never able to learn 

 anything of their breeding habits, and indeed they are birds very 

 rarely encountered.

Carnegie Museum : Pozo Azul de Pirris, Coronado de Terraba (Car- 



riker). Five skins. 



I found them quite common on the lower part of the Rio Grande 

 de Terraba, especially in the delta, where they have good feeding- 

 grounds on the mud-fiats left by the receding tide. Only a few were 

 noticed at Pozo Azul, along the Rio Grande de Pirris. They are 

 common in many places in Guanacaste, especially around the lower 

 portion of the Tempisque River. 



87. Plegadis guarauna (Linnaeus). 



Scolopax guarauna LiNN/EUS, Syst. Nat., ed. 12, T, 1766, 242. 



Plegadis guarauna Ridgway, Proc. U. S. Nat. Mus., I, 1878, 163. — Zeledon*

Zool. en C. R., 1891-2, 1893, 52 (El Pozo de Terraba, one specimen, not 



common). 



The above record by Mr. Cherrie is the only one I have seen of 

 the taking of this bird in Central America, although it would seem 

 quite natural that it should be found there. Seflor Zeledon gives the 

 bare record, but cites no specimen, so we cannot be positive concern- 

 ing his record.
