My National Geographic 'Birds of North America' says, in part, "
Northern Mockingbird [
Mimus polyglottos] . . . Song is a mixture of original and imitative phrases, each repeated several times. Often sings at night. Imitates other species' songs and calls. Both sexes sing in fall, claiming feeding territories. Call is a loud, sharp
check. Aggressive territorial defense; may attack any intruder."
Scrapple, you probably never saw these guys in Denver; they may sometimes breed in the higher elevations there, but almost never along the Front Range.
I've enjoyed many a concert sitting on my lanai as a mocker or maybe even a couple sing and sing and sing in the tree nearby.
