This species has often reminded me of the Robin Redbreast of Europe, to which it bears a considerable resemblance in form and habits. Like the Blue Bird the Redbreast has large eyes, in which the power of its passions are at times seen to be expressed. Like it also, he alights on the lower branches of a tree, where, standing in the same position, he peeps sidewise at the objects beneath and around, until spying a grub or an insect, he launches lightly towards it, picks it up, and gazes around intent on discovering more, then takes a few hops with a downward inclination of the body, stops, erects himself, and should not another insect be near, returns to the branch, and tunes his throat anew. Perhaps it may have been on account of having observed something of this similarity of habits, that the first settlers in Massachusetts named our bird the Blue Robin, a name which it still retains in that state.
Were I now engaged in forming an arrangement of the birds of our country, I might conceive it proper to assign the Blue Bird a place among the Thrushes.
