44 A NATURALIST [IN THE MAGDALEN JSLANDS. 
32. MELOSPIZA MELODIA, (Wits ha. 
(SONG SPARROW.) 
It cannot be considered as common; only two specimens 
were taken, but I have no doubt that it is a regular summer 
visitor, and breeds here. 
33. ¥UNCO HVEMALIS, (L.) Sci. 
(SNOWBIRD. ) 
An abundant species. They were very tame, and came 
around the house fearlessly. On July 18 I discovered a nest 
containing young birds nearly able to fly. The old birds 
showed their anxiety as I approached by flitting from one 
branch to another, sometimes almost within reach of my 
hand, continually uttering a short, clear “chip” of alarm. 
In a series of specimens measured, I found quite an 
appreciable difference in size; some adult birds were darker 
than others.
