thence into Chiriqui. It seems to be more abundant in Costa Rica, within 

 its range, than is D. c. ultramarina on the eastern side. I found it 

 very abundant all around Boruca in July, and later at Buenos Aires in 

 August and September, feeding in flocks on a small berry-like fruit.

 This form of Dacnis cayana is confined in Costa Rica to the Caribbean 

 lowlands and lower slopes, probably from about sea-level up to 2,000 feet. 

 It seems to be a rare bird and not many records are extant for its occurrence 

 in Costa Rica. It was taken by Carmiol at Angostura and by Zeledon 

 and Basulto at Bonilla, but in addition to these, the five skins which I 

 secured at El Hogar seem to be all of which I can find any record. My 

 specimens were taken August 16, December 6, and January 1. On 

 Dec. 6 there was quite a large flock of the birds in a low tree in a pasture 

 near the house, but after securing three, they flew away and I could not 

 find them again.
