Oh, Sweet sweet sweet plums.
You can put any mnemonic device to this bird's song, as long as you say it in the right cadence. I think this guy was singing to the plum bounty it found. (At second glance, they might be crabapples) . "The White-throated Sparrow comes in two color forms: white-crowned and tan-crowned. The two forms are genetically determined, and they persist because individuals almost always mate with a bird of the opposite morph. Males of both color types prefer females with white stripes, but both kinds of females prefer tan-striped males. White-striped birds are more aggressive than tan-striped ones, and white-striped females may be able to outcompete their tan-striped sisters for tan-striped males."
