How many black stripes typically mark the crown of an adult White-crowned Sparrow?
Answer
Five
Adult White-crowned Sparrows are distinguished by a striking pattern on their head composed of five black stripes separated by four white stripes that extend from the bill to the back of the head. This pattern is the source of the bird's common name. While the central white stripe is usually the widest, the configuration consists specifically of five distinct black bands alternating with the white ones.
