Answer to Bird Quiz #164: Crimson-collared Grosbeak

Our quiz this past week did not give everyone very much to work with. A good chunk of those that responded were able to figure it out though!

Last Week's Quiz:

How to Identify:

The difficulty of this bird quiz is not having a clear view of the bird.  Once, we realize what is going on with this bird we can pick out a few key field marks.  It’s quite easy to see that this bird has a yellowish-olive chest, olive crown and nape, limited black throat, and silvery base to the bill.  These features alone do not leave many options but let’s look at the shape.  The thick bill, rather thick-bodied look, and fairly long tail help us key in on the grosbeaks, tanagers, and similar species.  But given the field marks that are visible we can identify this as a Crimson-collared Grosbeak.  We can eliminate the incorrect answers of Yellow Grosbeak and Red Crossbill for a couple of reasons.  A Yellow Grosbeak would show a much brighter yellow chest and belly, larger bill, and black-and-white patterned wings.  A Red Crossbill would not show the black mask, silvery base to the bill, or the long tail that the quiz bird shows.  So we can safely identify our bird as a Crimson-collared Grosbeak.
