I believe this bird to be confined to the Pacific lowlands of Costa 

 Rica, for in all my collecting on the eastern slope I have never seen 

 it, nor are there any records for that side. It is of a very sluggish 

 nature and apparently feeds on frogs and lizards, for it is always found 

 in the vicinity of water, usually a sluggish lagoon or pond. In its 

 habits it somewhat resembles Urulritinga, but is still more sluggish.

A very rare bird in Costa Rica, but doubtless a resident. Mr. Lan- 

 kester' s bird was taken about May 5-10. I saw a bird on the edge of 

 the lagoon at the mouth of the Matina River in November, but was 

 unable to secure it. Mr. Nutting says that this bird is an inveterate 

 chicken-thief and associates with vultures, eating carrion.
