This picture shows the 3 essential ID characteristics that nail it down to a Hammond's Flycatcher: 1) long primary extension of the wing tips, 2) straight sides to a narrow, short bill, and 3) a dark lower mandible.
观察细节
In the first picture you can see the fairly significant eye-ring and a small, dark beak (Measuring the beak length and dividing it by the beak to back of head length gives a ratio of about .25. The Pacific Slope ratio is about .34.). The second shows the 3 essential ID characteristics that nail it down to a Hammond's Flycatcher: 1) long primary extension of the wing tips, 2) straight sides to a narrow, short bill, and 3) a dark lower mandible.
