Colophon

The animals on the cover of Web Development with Node and Express are a black lark (Melanocorypha yeltoniensis) and a white-winged lark (Melanocorypha leucopter). Both birds are partially migratory and have been known to range far afield of their most suitable habitat in the steppes of Kazakhstan and central Russia. In addition to breeding there, male black larks will also winter in the Kazakh steppes, while females migrate southwards. White-winged larks, on the other hand, fly farther west and north beyond the Black Sea during the winter months. The global range of these birds extends still farther: Europe constitutes a quarter to one-half of the global range of the white-winged lark and only five percent to a quarter of the global range of the black lark.

Black larks are so named for the black coloring that covers nearly the entire body of males of the species. Females, by contrast, resemble the coloring of the male in only their black legs and the black feathers of their underwings. A combination of dark and pale grays covers the rest of the female.

White-winged larks possess a distinctive pattern of black, white and chestnut wing feathers. Gray streaks down the white-winged lark’s back complement a pale white lower body. Males differ in appearance from females of the species only in the males’ chestnut crowns.

Both black and white-winged larks evince the distinctively melodious call that has endeared larks of all variations to the imaginations of writers and musicians ...
