Physical features to check

1. 1

   Plumage

   Overall feather coloration and pattern.

   Adults have bright yellow underparts, a prominent black crest, and a black throat and breast band that extends down the belly as a broad central stripe. The upperparts are olive-green to greyish-green. The wings are dark with two distinct white wing-bars. The tail is dark with white outer tail feathers. A distinctive black eye-stripe runs through the eye, contrasting with yellow cheeks and a yellow supercilium.

2. 2

   Beak shape

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

   Small, conical, sharp, and black.

3. 3

   Eye color

   Iris color and any distinctive eye markings.

   Dark brown.

4. 4

   Leg color

   Leg and foot color.

   Dark grey to blackish.

5. 5

   Distinguishing features

   Standout features that separate this species.

   The prominent black crest, bright yellow underparts with a broad black central stripe, and two white wing-bars are key identification features. The facial pattern of black eye-stripe, yellow cheeks, and yellow supercilium is also diagnostic.

6. 6

   Juvenile appearance

   How young birds differ from adults.

   Juveniles are duller overall, with less vibrant yellow underparts, a less distinct black central stripe, and a shorter, less prominent crest. The upperparts may be browner, and the facial markings less sharply defined.

7. 7

   Seasonal changes

   Plumage variation between breeding and non-breeding seasons.

   No significant seasonal plumage changes are observed. Plumage remains consistent throughout the year, though wear and tear might make it appear slightly duller before molting.

8. 8

   Sexual dimorphism

   How males and females differ.

   Males and females are generally similar in plumage, though males may have slightly more intense coloration and a broader, more prominent black central stripe on the underparts. The crest might also be slightly larger in males.

Key field marks

• Crest. Look for the prominent, erect black crest on the head, a key feature distinguishing it from many other small passerines.
• Underparts Coloration. Observe the bright yellow underparts with a broad, distinct black stripe running down the center of the breast and belly.
• Facial Pattern. Note the black eye-stripe contrasting with bright yellow cheeks and a yellow supercilium (eyebrow).
• Wing-bars. Identify the two clear white wing-bars on the dark wings, which are visible even in flight.
• Upperparts. The upperparts are typically olive-green to greyish-green, providing a contrast to the bright underparts.
• Vocalization. Listen for its distinctive, ringing 'chee-wee, chee-wee' song or sharp 'chick-a-dee' calls, which are often the first indication of its presence.
