All the while the Junco with open beak is uttering the most plaintive notes. It is certain that this bird would act at once if given the opportunity.

It would seem that such might be a very favorable condition for the appearance of imitation, and certainly no small amount of suggestion and the "following instinct."
In the twenty-fifth test and those immediately following the boiled rice was omitted in order to see what effect this would have on the efforts of the Sparrow.
