Passer ina ovanea . 
Concord, 
1893. 
July 3. 
Mass. Plight Song. 
While walking along the Estabrook road this evening after 
sunset I saw an Indigo Bird mount into the air over an open 
, field and sing on wing. A few low stuttering notes were pre- 
fixed to the usual song which was delivered as the bird was 
rising and ended when it had attained a height of about 40 ft. 
It then closed its wings and shot down a steep incline into 
some bushes on the edge of the field. I do not recall seeing 
I 
i 
see in g this species sing on wing before.
