We found this heron especially abundant in the mangrove swamps

Only one specimen of the American egret has been obtained at the 

 Galapagos ; it was taken by the Harris expedition and determined by 

 Rothschild and Hartert to be the same as South American birds. 

 Baur and Adams reported finding on Albemarle " a rookery of white 

 herons." We saw one individual on a small island in the center of a 

 lake in the bottom of the large tufa crater just south of Tagus Cove, 

 Albemarle.
