1890 Mass .- Parus attricapillus . 



June 28 Martha's Vineyard .- 



Three birds heard singing one in oak scrub, the other two 

 in apple orchards. Song of one normal ; of the other two 

 peculiar in that both notes { or all three) v/ere on the same 

 key or pitch v/hich was that of the normal first note.- I did not 

 see any of these birds.'
