 This species seems to occur all over the country up to 4,000 

 feet, wherever suitable conditions prevail. I found them fairly- 

 numerous in a lagoon at the mouth of the Matina River, where they 

 were quite partial to the large patches of water-hyacinth. When 

 flushed from these they would often fly into the Silico palms lining 

 the banks of the lagoon and remain perfectly quiet among the leaves, 

 where they were extremely difficult to see, their color seeming to 

 blend perfectly with the dark green of the palm-leaves.

Evidently not very abundant so far south as Costa Rica. It is 

 known to be found in the Laguna de Ochomogo and at Las Concovas 

 near Cartago, at La Laguna del Infernillo at Juan Vinas, and probably 

 at various points along the coast. I shot one bird in the lagoon at 

 the mouth of the Matina River on November 14, 1907, but did not 

 preserve it. It was swimming along the edge of the water-hyacinths 

 and seemed very tame. I have not been able to learn at what date 

 they arrive in the autumn, or leave in the spring.
