1392. Mass. Zenaida macroura. 
July 29. Concord . - safety either some time yesterday or this morning. I ; 
(NO. 2. ) did not see either of the parent "birds on the 27th and to-day 
I could find only one Dove on my entire premises, an old male 
which I saw flying into the woods on Davis's Kill where, prob- 
ably the young were in hiding. 
I found this nest July 4th when it contained the comple- 
ment of two eggs. Tliese( at a distance of 15 feet) looked 
slightly incubated. One was nearly a third larger. than the 
other. The larger egg hatched on the I5th, the smaller on the 
following day. It follows that the period of incubation with 
this species is at least II days and that the young remain in 
the nest only IS or 14 days.

nest.
