How to identify the Woodpecker (General)

To correctly identify the Woodpecker (General) (Varie selon l'espèce (e.g., Dendrocopos major, Picus viridis).), check each of these features. Birds can be tricky: habit, habitat, and call often confirm a sighting that a single photo cannot.

Size at a glance

Length

14-50 cm (5.5-20 inches)

Wingspan

25-80 cm (10-31.5 inches)

Weight

20-500 g (0.7-17.6 oz)

Physical features to check

1. 1

   Plumage

   Overall feather coloration and pattern.

   Highly variable by species. Common patterns include black and white barring, green, red, yellow, and brown. Many species feature red or yellow patches on the head or nape. Plumage is generally cryptic, blending with tree bark.

2. 2

   Beak shape

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

   Strong, chisel-like, and pointed, adapted for drilling into wood. Color is typically dark grey or black, sometimes lighter at the base.

3. 3

   Eye color

   Iris color and any distinctive eye markings.

   Dark brown, red, or yellowish, depending on the species.

4. 4

   Leg color

   Leg and foot color.

   Grey to dark grey, zygodactyl feet (two toes pointing forward, two backward) for gripping tree trunks.

5. 5

   Distinguishing features

   Standout features that separate this species.

   Stiff tail feathers used as a prop against tree trunks, zygodactyl feet, and a long, barbed tongue for extracting insects. Many species have distinctive head patterns, often with red or yellow markings.

6. 6

   Juvenile appearance

   How young birds differ from adults.

   Juveniles often resemble adults but may have duller plumage, less defined markings, or more extensive red on the crown (e.g., in Great Spotted Woodpecker, both sexes have red crowns as juveniles).

7. 7

   Seasonal changes

   Plumage variation between breeding and non-breeding seasons.

   Generally minimal seasonal plumage changes. Some species may show slight variations in feather wear or brightness, but no distinct breeding vs. non-breeding plumages.

8. 8

   Sexual dimorphism

   How males and females differ.

   Often present, with males typically having more extensive or brighter red/yellow markings on the head or nape than females. In some species, males and females are very similar.

Key field marks

• Size and Overall Coloration. Note the bird's size (small like a sparrow, medium like a thrush, large like a crow) and primary plumage colors (e.g., black and white, green, all black). This immediately narrows down possibilities.
• Head and Nape Markings. Look for red or yellow patches on the crown, nape, or forehead. Note if these are present in both sexes, or only in males, and their extent. This is a key sexual dimorphism indicator.
• Back and Wing Patterns. Observe the pattern on the back and wings. Is it solid black, barred, or does it have large white patches (e.g., 'shoulder patches' on Great Spotted Woodpecker)? Are the flight feathers barred?
• Undertail Coverts. Check the color of the feathers under the tail. Many species have distinctive red or pink undertail coverts.
• Vocalizations and Drumming. Listen carefully to calls and drumming patterns. Each species has a unique call repertoire and drumming rhythm/duration, which is often more reliable than visual identification in dense foliage.
• Foraging Behavior. Note how the bird forages. Is it actively pecking and excavating, gleaning insects from bark, or drilling for sap? This can provide clues to the species (e.g., sapsuckers).
