STREAKED HERON 



in the Zone or not. On the Pearl Islands a 

 dark resident subspecies, maculata (Vieillot) 

 occurs rather commonly. 



7. Butorides striata (Linnaeus) 

 Streaked Heron 



Length 370 mm. (14.50 in.). 



Sexes alike. Adult. Top of head greenish 

 black, a black streak under eye; sides of head 

 and neck gray; a stripe of white with brown 

 streaks down the foreneck, this stripe widens 

 on the chest; back mostly grayish green; wings 

 grayish, the coverts margined with buff, the 

 long scapulars glossy grayish green; lower back 

 and rump pale gray; tail greenish black; breast 

 and under parts gray, paler on abdomen. Bill 

 dark, yellow at the base; feet yellow. 



Similar in habits to Butorides virescens, fre- 

 quenting the same localities. The gray neck 

 and prevailing grayer colors of the plumage 

 readily distinguish it from that species.

 127 mm. (5.00 in.).
