Jasper Jay in "The Search"

After telling Mr. Crow what he was going to do to the strange bird, which he had never seen, but only heard, Jasper Jay renewed his search for the unknown.
There was not the slightest doubt in his mind that the stranger could out-scream him. And he knew he could never be happy so long as such a loud-voiced rival remained in the neighborhood.
Jasper hoped, at least, that the newcomer was not too large.
"He can't be very big, or I'd have found him before this," he reassured himself.
