cachila

a small bird (possibly the long-tailed reed finch, Donacospiza albifrons), of brown color with dark streaks and yellowish throat and belly, of terrestrial habits, and that performs acrobatic flights in time of mating

Uncertain. Likely derived from cachirla.

An antique car, especially a veteran car from the early decades of the 1900s.; A car that is old and broken down from use.

Likely in reference to the dust the cachila kicks up during its run-up before flight, like the dust the first cars (now antique) would kick up on the dirt roads of the time.
