a tt 
Chrysomitris tristis. 
Middlesex County, Mass. 
A nest in a tall maple in the Maple Swamp, twenty- 
five feet above the ground an inaccessible; the sitting 
female kept up a continual twittering which guided me 
to the spot. This seems to bo a regular habit as I 
noticed at Lake Umbagog in 1873. 
Several v/hieh I shot to-day had their crops filled 
exclusively with green pulpy seeds. The members of this 
genus eat very few insects at any season.
