A WINTER WITH THE BIRDS IN COSTA RICA

one and which had an enormously broad top, spreading certainly more than 150 
and possibly 200 feet) macaws, parrots and parrakeets were exceedingly numerous 
and noisy, the species collected being Ara macao, Amazona auripalliata, and A. 
salvini, and Brotogerys jugularis. A rare toucan Pteroglossas frantzii was also found, 
likewise Trogon bairdii , both of which were obtained. Several times we saw the 
snow-white cotinga with yellow bill ( Carpodectes antoyiia Zeledon) and although 
one was shot it could not be found. 
Among the biscoyal palms and tall ferns in more open parts of the forest, as 
well as in a clearing, grown up with bushes and tall weeds, the Pacific red-backed 
tanager ( Ramphoccelus cos/arice?isis Cherrie) was abundant and as the National 
Museum possessed only one specimen of this bird, and that a young male, we of 
course collected a fine series. 
IN THE POTRERO AT COLIBLANCO 
The next place to engage our attention was Bonilla, on the Atlantic slope, 
whither we proceeded by way of the railroad to Limon, leaving the train a few 
miles below the town of Turrialba and walking from there to our destination, 
our outfit being transported on horses up the steep and rough mountain trial. 
Bonilla is an estate of 3000 acres belonging to Don Francisco Lopez Calleja. 
who, together with his partner and manager, Don Juan Gomez, of Turrialba, 
made every possible provision for our comfort and the successful prosecution of 
our work. Although Bonilla is in the humid so-called hot zone, its climate was 
by no means uncomfortable; but owing to the roughness of the ground and density 
of vegetation, collecting was very difficult except in the cleared areas. The latter 
( potreros or pastures), however, were wonderful places on account of the 
great variety and abundance of birds and the ease with which they were procured.
