the “White Throats” arrive in late fall and leave in mid-spring
roughly corresponding to the timing of the Junco
when they finally start singing in the spring I know they won’t stay much longer
there are two color morphs - white-striped and tan-striped
each sex usually pairs with a different color morph
keeping both colors equally represented in the population
science might tell us there is a simple genetic advantage to this
keeping the gene pool diverse and enriched - pulling the species forward
perpetuating the song
