This noisy jay was very common at Guayabo, but less so at Coli- 

 blanco. They usually rove about in small bands (5 to 10) screaming 

 a great deal. They are magpie-like in habits, and often visit the 

 vicinity of dwellings.

This interesting little bird haunted vine-hung trees, many indi- 

 viduals being found together. It is very active, flitting quickly 

 from twig to twig and keeping almost constantly in the deep shade. 

 Occasionally one will fly out and hover in front of a flower after t he 

 manner of a humming-bird. The natives sometimes refer to this 

 bird as "Azul." The males look quite blue in the sunlight. One 

 female had been incubating.
