The cone of Pinophyta (conifer clade) contains the reproductive structures. The woody cone is the female cone, which produces seeds.

One way to distinguish between them is by their cones. Each has barbs at the end of the scales. The sharp Jeffrey pine cone scale barbs point inward, so the cone feels smooth to the palm of one's hand when rubbed down the cone.

The woodpecker adults are characterized by being 7 inches (18 cm) long, with a black head, white cheek patch, and barred back with black and white stripes that give the appearance of a latter. [ 12 ] [ 16 ] In males, a red strip atop the head is only visible when young or up close.
The pine grosbeak was formally described in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his Systema Naturae under the binomial name Loxia enucleator. [2] The type locality is Sweden. [3] It is now the only species placed in the genus Pinicola that was erected in 1808 by the French ornithologist Louis Pierre Vieillot.
