White-throated Sparrows Migrating

 

White-throated Sparrow (Zonotrichia albicollis) numbers are building in northern New England as they head towards the mid-October peak of their migration south.  Even though they are no longer constantly singing their “Poor Sam Peabody-Peabody-Peabody” song, which allows quick  identification, White-throated Sparrows’ white throats, striped crowns and yellow lores (the area between the eye and the bill) make them one of the easier sparrows to identify.  Don’t be surprised if you see this bird with a tan, and not white, crown.  There are two color forms, white-crowned and tan-crowned.  Interestingly, an individual bird almost always mates with a bird of the opposite color form. Males of both color types prefer females with white stripes, but both kinds of females prefer tan-striped males.

    Please explain how you know who they mate with?

    • Cornell — they know everything you would possibly want to know about birds — plus Birds of North America Online! Apparently the research was done in Manomet.

    Hi Mary,

    As I recall, the male and female color preferences in mates was discovered via color banding not too far from here at Manomet. Have I got that right?

    Thanks,

    Meade

    • Hi Meade,
      You’re far more informed about this than I. That’s so interesting that the research was done at Manomet!

    Now that you mention it, I know I have seen both color stripes here. Fascinating!
