 Like many other species which are so rare in Costa Rica, the range of 

 this bird does not normally include that country, and it is only an 

 occasional straggler which is sometimes taken. It is a common bird 

 further north.

This exceedingly rare and local species of hummingbird was dis- 

 covered by M. Adolph Boucard, at Puntarenas, probably in January, 

 1877, where he procured a few specimens in the mangroves near the 

 town. It was known only from these type specimens for the next 

 twenty-eight years, until finally in 1905, Mr. Robert Ridgway in 

 company with the eminent Costa Rican ornithologists, Senores Zele- 

 don and Alfaro, discovered its habitat and secured about a dozen speci- 

 mens at Pigres on the Pacific coast not far from Puntarenas. They 

 found it in the mangroves along the salt-estuaries at that point. 

 Mr. C. H. Lankester secured a single male at Palo Verde on the 

 Tempisque River in 1906, but saw no others. I believe this bird was 

 taken in the mangroves also. In 1907, when I made atrip to the Ter- 

 raba region, I determined to put forth every effort to secure the bird, 

 and hunted carefully in the mangroves at Puntarenas for it without 

 result. However, I was more fortunate at the mouth of the Rio Grande 

 de Terraba, where I found it fairly abundant in one small spot in the 

 mangroves along one of the branches of the delta of that river, and was 

 enabled to secure a splendid series of both males and females. These 

 specimens have been distributed among various museums in this 

 country and in Europe, so that this bird, so long unknown and rare, is 

 now fairly well known.
