<P> The genus name Pheucticus is from Ancient Greek pheuktiko, "shy", from pheugo, "to flee", and the specific ludovicianus is from New Latin and refers to Louisiana . </P> <P> Adult birds are 18--22 cm (7.1--8.7 in) long, span 29--33 cm (11--13 in) across the wings and weigh 35--65 g (1.2--2.3 oz). Grosbeaks measured during migration in the West Indies averaged 43 g (1.5 oz), while those banded in Pennsylvania average about 45 g (1.6 oz). Very little sexual dimorphism in size is seen; females were found to be marginally smaller in standard measurements, but in some seasons were marginally heavier than males when banded in Pennsylvania . At all ages and in both sexes, the beak is dusky horn - colored, and the feet and eyes are dark . </P> <P> The adult male in breeding plumage has a black head, wings, back, and tail, and a bright rose - red patch on its breast; the wings have two white patches and rose - red linings . Its underside and rump are white . Males in nonbreeding plumage have largely white underparts, supercilium, and cheeks . The upperside feathers have brown fringes, and most wing feathers white ones, giving a scaly appearance . The bases of the primary remiges are also white . The coloration renders the adult male rose - breasted grosbeak (even while wintering) unmistakable if seen well . </P> <P> The adult female has dark grey - brown upperparts--darker on wings and tail--, a white supercilium, a buff stripe along the top of the head, and black - streaked white underparts, which except in the center of the belly have a buff tinge . The wing linings are yellowish, and on the upperwing are two white patches like in the summer male . Immatures are similar, but with pink wing - linings and less prominent streaks and usually a pinkish - buff hue on the throat and breast . At one year of age--in their first breeding season--males are scaly above like fully adult males in winter plumage, and still retain the immature's browner wings . Unlike males, females can easily be confused with the black - headed grosbeak (Pheucticus melanocephalus) where their ranges overlap in the central United States and south - central Canada . The rose - breasted grosbeak female has slightly darker brown markings on the underside, paler rather yellowish streaking on both the head and wings and paler, pinkish (rather than bi-colored) bill when compared to the female black - headed grosbeak . A potential confusion species also is the female purple finch (Haemorhous purpureus), but that species is noticeably smaller with a less robust bill and a notched tail . </P>
