How to identify the Twite

To correctly identify the Twite (Linaria flavirostris), check each of these features. Birds can be tricky: habit, habitat, and call often confirm a sighting that a single photo cannot.

Physical features to check

1. 1

   Plumage

   Overall feather coloration and pattern.

   Overall streaky brown plumage. Upperparts are heavily streaked dark brown on a buffy-brown background. Underparts are paler, buffish-white, with streaking on the flanks. Rump is unstreaked and often pinkish in breeding males. Wings are dark with pale edgings to the flight feathers, forming two indistinct wing-bars. Tail is dark and forked.

2. 2

   Beak shape

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

   Small, conical, and pointed. Yellowish-horn in winter, becoming greyish-black in breeding season.

3. 3

   Eye color

   Iris color and any distinctive eye markings.

   Dark brown.

4. 4

   Leg color

   Leg and foot color.

   Dark brown to blackish.

5. 5

   Distinguishing features

   Standout features that separate this species.

   Lack of red on the head or breast (unlike Linnet), unstreaked pinkish rump (in breeding male), and a distinctive yellow bill in winter. The 'twite' call is also a key identifier.

6. 6

   Juvenile appearance

   How young birds differ from adults.

   Juveniles are similar to adult females but are more heavily streaked overall, including on the rump, and lack any pink flush. Their plumage is generally duller and less defined.

7. 7

   Seasonal changes

   Plumage variation between breeding and non-breeding seasons.

   In winter, the bill is bright yellow with a dark tip, and the plumage is generally duller and more buff-brown. In breeding season, the bill darkens to greyish-black, and males develop a prominent pink rump. The streaking becomes more defined.

8. 8

   Sexual dimorphism

   How males and females differ.

   Males in breeding plumage develop a distinctive pink flush on the rump, which is absent or much fainter in females. Females are generally duller and more heavily streaked.

Key field marks

• Plumage. Look for a small, streaky brown finch. The overall impression is of a 'scruffy' brown bird. Note the lack of any red on the head or breast, which immediately distinguishes it from a breeding male Linnet or Redpoll.
• Rump Color. In breeding males, look for an unstreaked pink flush on the rump. This is a key diagnostic feature. Females and juveniles have a streaked rump.
• Bill Color. Observe the bill color. In winter, it is distinctly yellow with a dark tip. In the breeding season, it darkens to greyish-black. This is a crucial differentiator from Linnets.
• Call. Listen for the characteristic dry, nasal 'twee-it' or 'twite' call. This is often the first and most reliable way to identify them, especially in flight or when in flocks.
• Habitat. Consider the habitat. Twites prefer open, treeless moorlands, uplands, and coastal areas, often where heather or gorse is present. Linnets are more often found in farmland and scrub with taller bushes.
• Behavior. Watch for their ground-feeding behavior, often in flocks, meticulously picking seeds. Their undulating flight pattern is typical of finches.
