The Blue Grosbeak is an unfamiliar bird to most eastern students.
Ridgway states that its haunts resemble those of the Field Sparrow or
Indigo Bunting. Its call is a strong, harsh _ptchick_, its song a
beautiful, but rather feeble warble. The nest is usually built in bushes
and the 3-4 pale bluish white eggs are laid in May.

ROSE-BREASTED GROSBEAK

_Zamelodia ludoviciana. Case 7, Figs. 25, 26_

The male needs no introduction; the streaked
plumage of the female betrays her Sparrow
ancestry; the white stripe over her eye is a
conspicuous mark. Young males in the fall resemble
the female, but have a rose-tinted breast. L. 8.

_Range._ Nests from central Kansas and central New
Jersey north to Canada, and, in the mountains,
south to northern Georgia; winters in the tropics.

Distinguished alike by plumage and song, the Rose-breast is one of our
most notable bird citizens. His song resembles in form that of the
Robin, but has a more lyrical, flowing, joyous quality, and, unlike the
Robin, he often sings while flying. The call-note of both sexes is a
sharp _peek_ which, like the Cardinal's _cheep_, seems too small for the
bird.

The Rose-breast lives and nests in woodland, particularly
second-growths, building a frail nest ten to twenty feet from the
ground. The 4-5 blue, brown-marked eggs are laid the latter half of May.

INDIGO BUNTING

_Passerina cyanea. Case 7, Figs. 23, 24_

The male, well seen, is unmistakable. The female
is very 'sparrowy' and, unless one gets a
suggestion of blue in her plumage, can best be
identified by her unsparrow-like, sharp _pit_. L.
5-1/2.

_Range._ Nests from Georgia and Louisiana to
Canada; winters in the tropics.
