Question 4 |
Now look at the greater coverts on each of the three species above. Two species have all of the greater coverts more or less the same pattern, and one species has a strikingly different color pattern on some of its greater coverts. Which species has non-uniform greater coverts?
Prairie Warbler | |
Yellow Warbler | |
Cape May Warbler |
Question 4 Explanation:
Correct! Cape May Warbler. The median coverts are bright white, and merge with white on several of the middle greater coverts, But the innermost (upper) and outermost (lower) greater covert are dark gray with greenish edges. No other warbler shares this pattern, and neither does the female Cape May. You can see more photos, including a female, here - http://briansmallphoto.com/cape_may_warbler.html
