SLATE-COLORED GROSBEAK 



some brownish buff or dull tawny edgings to the 

 wings. 



Common in open places. Often to be seen 

 with Sporophila aurita on the sides of the Gam- 

 boa road. Hallinan writes of a male in Balboa, 

 "This bird would perch on a twig and after 

 short intervals would jump vertically about a 

 foot and alight again in the same place, uttering 

 a few short notes during the jump." I ob- 

 served this performance on several occasions at 

 Quarry Heights.
