2. 2

   Beak shape

   Shape and color of the bill: a key field mark.

   Long, heavy, straight, and dagger-like bill, dark gray to black in color.

   Iris color and any distinctive eye markings.

   Dark brown.

4. 4

   Leg color

   Leg and foot color.

   Small, weak, and dull grayish-orange legs and feet.

5. 5

   Distinguishing features

   Standout features that separate this species.

   Large, shaggy crest; long, heavy, pointed bill; slate blue-gray and white plumage with a prominent breast band; distinctive rattling call.

6. 6

   Juvenile appearance

   How young birds differ from adults.

   Juveniles resemble adults but have a more mottled or rusty wash on the breast band, which can sometimes appear as two bands in both sexes, similar to an adult female. The bill may also be slightly shorter and less robust.

7. 7

   Seasonal changes

   Plumage variation between breeding and non-breeding seasons.

   No significant seasonal plumage changes; plumage remains consistent year-round.

8. 8

   Sexual dimorphism

   How males and females differ.

   Females are more colorful than males, possessing an additional rusty band (rufous flank band) across the lower belly/flanks, below the blue-gray breast band. Males only have the single blue-gray breast band.

Key field marks

• Size and Shape. Look for a medium-sized, stocky bird with a large head, shaggy crest, and a long, heavy, pointed bill. It often perches hunched over water.
• Plumage. Note the slate blue-gray upperparts and white underparts. The prominent blue-gray breast band is key. Females have an additional rusty band below the blue-gray one.
• Behavior. Observe its characteristic hunting style: perching patiently over water, then diving headfirst. Also, watch for its direct, rapid flight low over water.
• Vocalization. Listen for its unmistakable loud, dry, rattling call, often given in flight. This is one of the most reliable identification features.
