Blue Grosbeak Accessory Pouch

The Blue Grosbeak (Passerina caerulea) is an uncommon bird of riparian woodland edges. The thick bill enables it to crush both hard seeds and insects’ exoskeletons. As in all blue birds, their color is due to the play of light in the microscopic structure of the feathers, not to a blue pigment. Male Blue Grosbeaks become fully blue when they are about 1 year, 3 months in age—until then, they typically have only irregular blotches of blue. Females are a much less conspicuous tawny brown, better for camouflage as they incubate.

The birds featured here are just a few of the 79 Blue Grosbeak specimens in our collection, ranging in date from 1876 to 2020.

This eye-catching flat pouch can be used for collecting and toting pretty much anything. Made of polyester with non-woven laminate interior. Small size measures approximately 8.25” x 6” and large measures approximately 11.5” x 8. 25”.
