Nest with one egg. 
Found i.est with one fresj^ egg. 
One to-day. 
Something must have happened to the Cuckoos as I

Most, one fresh egg.

Heard a male, 
One shot. 
Very scarce this year.

Shot three in lexington. This species is much 
commoner than the diackbill this season. I an now 
sure of the difforonco in their notes; that of' the pres- 
enu specios is a long, hoarse rattle, or sometimes a deep 
dove-like cooing in notes on ono syllable; coo , coo , con 
coo_. The Black-bill has a softer coo of never'' 
less than two, and freqently as many as four syllables. 
Thus: coo- coo- coo-coj); this is I 
think its only iioto. 
I settled the differonco in the Cuckoos notes to-d-.y 
beyond any question. T?y observations ofi Juno 5 are 
correct as far as they go. The Black-billed Cuckoo 
:: has, however, a proliminarv cuyi-cuc-cigc etc. very like 
that othe Yollow-bill, but uttered more rapidly, and ^ 
little softer and loss guttural; both sexes of both 
specxos use all the notes in common, so that those birds 
caiA 
scarcely be said to have a real sont 
1875 . 
_ They are very scarce t^is season, thoreas the Black- 
bill IS more than ordiharily numerous.
