C yano oit ta cristata. 
Concord, Mass. Singular vocal performance. 
| 1396. A little after sunrise this morning a Blue Jay came into 
| Apr. 13. the mountain ash in front of my window at the Keyes's and at 
short interfals, for 15 to 20 minutes, made a long series of 
i 
the most singular sounds - clucks, chuckles, low whinings 
(like Vireo solitari\is ) and (more frequently than any of the 
other calls) a noise precisely like that produced by twisting 
I 
a wet cork in the neck of a bottle and hence very like one of 
i 
the Eave Swallows wellknown notes. The Jay would keep up 
i 
. 
this medley of sounds without the slightest pause for two 
minutes or so, then stop for a minute before beginning again. 
At the end of it all he screamed a few times before flying 
away. It was a very grotesque ana indeed laughable seranade. 
A Jay at take Umbagog last autumn .did precisely the same thin
