Mr. O. Salvin states (Ibis, III, p. 352) that he found this species, though not of very common occurrence, pretty generally distributed, in winter, throughout Vera Paz. He met with it on the Plains of Salamà, and all the collections from the warmer districts to the northward of Coban contained specimens. It was found by Mr. George H. White near Mexico.
Wilson speaks of this bird as retired and solitary, and also as a scarce species, and as having but few notes, its most common one being a loud chuck. He was, however, aware that at times they have a few low sweet-toned notes. He mentions their being kept in Charleston in cages, but as seldom singing in confinement. He fed a caged bird of this species on Indian corn, which it easily broke with its powerful bill; also on hemp-seed, millet, and berries. He speaks of them as timid, watchful, silent, and active.
Mr. Audubon was, apparently, somewhat at fault in regard to the peculiarities of this species. His accounts of the eggs of the Pyranga æstiva are entirely inapplicable to that species, and, so far as I know, apply to no other bird than the Blue Grosbeak, to which they exactly correspond. He makes no mention and gives no description of the eggs of the latter. His statements as to the nest appear to be correct.
Dr. Bachman kept several of these birds in an aviary; two of these mated, took possession of the nest of a Cardinal Grosbeak, which they drove off, and laid two eggs that were unfortunately destroyed. In the aviary these birds were silent. Mr. Audubon kept one, in confinement, with him in Edinburgh. It had been raised from the nest. This bird frequently sang in the night, and before dawn. It was extremely tame, coming out or going into its cage at pleasure, perching on the head-dress of Mrs. Audubon, or on the heads of other members of the family, alighting on the table and feeding on almost anything given to it. If a gold or silver coin was thrown upon the table he would go to it, take it up in his bill, and apparently toss it about with pleasure. After bathing he would go to the fire and perch on the fender to dry himself. He would attack other birds, if put into the cage with him. In feeding he sometimes held his food in his claws like a Hawk.
The eggs of this bird are of a uniform light-blue color, and most resemble those of the Sialia arctica, but are larger and of a lighter color. Their color is quite fugitive, and readily fades into a dull white upon even a slight exposure to light. They are of an oval shape, equally rounded at either end, and measure .98 of an inch in length by .65 in breadth.
