The common buttonquail resembles the common quail, it has streaked sandy brown upperparts, buff underparts with black flank markings, and a plain face. In flight, a whitish wingbar contrasts with the grey wing.
By the meteorological calendar, winter always starts on 1 December. The seasons are defined as Spring (March, April, May), Summer (June, July, August), Autumn (September, October, November) and Winter (December, January, February).
Winter begins December 22. First day of Spring is March 20. And Summer starts June 21. Depending on where you are in the US, these dates are sometimes sort of goofy .... winter *weather* starts in many northern areas by mid-November, for example. (or even earlier!)
