[4] C. becki has been found to be the product of a double colonization event beginning around 199,000 years ago, and had been formed through introgression, where greater male selectivity was exhibited by purebred females in one of the lineages.

[5] It is most commonly found on the northern, western, and southwestern slopes of Volcán Wolf,[6] the volcano that it is named for.

Having evolved to live in a specific environment, C. becki only occupies an estimated range of about 263 square kilometers.

[7] The specific name, becki, is in honor of American ornithologist Rollo Howard Beck.

[8] The preferred natural habitats of C. becki are forest and shrubland.
