When it finds the right spot, it is not very particular about nest-building.

A jumble of weeds, twigs, roots, and sometimes rags or bits of paper, serves to hold its light-blue eggs with brown markings.
"If it be ever right to cage a wild bird, you may make a prisoner of this Grosbeak; but remember, you must take a young male before it has known the joys of freedom, and give at least a half-hour every day to taking care of him.

Then he will grow to love you and be a charming pet, living happily and singing gladly; but under any other circumstances it is less cruel to shoot one than to make it a prisoner." The Rose-breasted Grosbeak Length about eight inches.
Male: black on the head, back, wings, and tail; the belly, rump, several spots on the wings, and three outer tail-feathers, white; rose-colored breast and wing-linings; bill white and very heavy.
Female: streaked brownish above and below, without any rosy color, but orange-yellow under the wings; she looks like an overgrown Sparrow with a swelled face.

THE INDIGO BIRD (THE BLUE CANARY) "Blue birds and blue flowers are both rare; you can count our really blue birds on the fingers of one hand, and a Blue Canary is even stranger than a green rose or a black tulip.
"The Indigo Bird has many of the Canary's gentle ways, and though his music is not so fine or varied as that of the Goldfinch or Song Sparrow, he sings a sweet little tune to his brown mate on her nest in the bushy pasture.
"She is fortunate in having a dull dress; for, if she were as splendidly blue as her husband, nesting would be a very anxious occupation for her.
Indeed, her poor mate has anything but an easy time; his color is so bright that everybody can see him at a glance, and when he picks up grass-seed in the streaming sunlight, his feathers glisten like sapphires." "We saw an Indigo Bird yesterday!" cried Nat and Dodo together.

"It was in the geraniums by the dining-room window, eating the seed I tipped out of my Canary's cage when I cleaned it," continued Dodo.
