Two skins. 



This is a common heron throughout the lower parts of the country 

 on both slopes, frequenting the edges of streams and marshy pastures, 

 but is very shy as a rule and hard to approach. It is also found in 

 the interior, but in fewer numbers. I have never seen more than two 

 together and usually they are to be found singly.

 Carnegie Museum : Guapiles, El Pozo de Terraba (Carriker). Five 



skins. 



With the exception of Buterides virescens maculata, the most abun- 

 dant heron in Costa Rica. While not so abundant in the highlands, it 

 is to be seen on both the Pacific and Caribbean lowlands in consider- 

 able numbers. They are very fond of feeding in wet or marshy pas- 

 tures, and a flock can almost always be found in pastures of any size. 

 They also frequent the streams.
