Zenaidura macroura 
July 14. 
(NO. 2) 
Concord .- started off along the ground alternately fluttering Dovers 
and walking. X did not follow her and she did not return while nest. 
I was near the nest. As an imitation of the behaviour of a 
I 
badly-wounded or rather dying bird I have never seen anything 
equal to the performance just described. It was not accompa- 
nied by any vocal sounds whatever. Perhaps the most intereat- 
ing thing connected with it v:ts the fact that the nest about 
which all this fuss was made was in a tree and the eggs still 
unhatched . When I looked at them a few minutes later I noticed 
for the first time that one was fully a third larger than the 
other. The "runt" egg loked transparent and infertile but the 
larger egg was dark colored and evidently near hatching. After 
descending to the ground I drove away the Jays and left the v'l 
place. 
July 15. Concord.- Visiting the Carolina Dove's nest at 6 P. M. I found 
The Dove started from her nest just as I stopped under it 
and fluttered downward through the branches much as she did 
yesterday but on this occasion she did not repeat the wounded 
bird performance but on reaching the ground merely alighted and 
stood erect and motionless looking at me. When I moved forward 
the female sitting facing H. as on my first visit (July ) 
with her head raised. This confirms my conclusion that the 
crouching or flattened attitude which she presented yesterday 
was due to the presence of Jays in the tree above her. There 
were no Jays near the place this evening.
