How to identify the Lineolated Parakeet

To correctly identify the Lineolated Parakeet (Bolborhynchus lineola), 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.

   Predominantly emerald green, with a darker green crown and nape. The back, wings, and flanks are finely barred with black, giving a 'lineolated' or laddered effect. The primary coverts and flight feathers are blackish with blue-green edges. The underparts are a lighter green, often with less prominent barring. A distinctive black patch is present on the lesser underwing coverts.

2. 2

   Beak shape

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

   Small, hooked, and horn-colored (pale yellowish-brown) with a darker tip.

3. 3

   Eye color

   Iris color and any distinctive eye markings.

   Dark brown with a narrow, pale grey periophthalmic ring.

4. 4

   Leg color

   Leg and foot color.

   Pinkish-grey to grey.

5. 5

   Distinguishing features

   Standout features that separate this species.

   The fine black barring across the back and flanks is the most distinctive feature. The black patch on the underwing coverts is also a key field mark, especially in flight. Their stocky build and relatively short tail are also characteristic.

6. 6

   Juvenile appearance

   How young birds differ from adults.

   Juveniles resemble adults but may have slightly duller plumage and less distinct barring. The black underwing patch may be less pronounced in very young birds.

7. 7

   Seasonal changes

   Plumage variation between breeding and non-breeding seasons.

   No significant seasonal plumage changes.

8. 8

   Sexual dimorphism

   How males and females differ.

   Minimal to none. Males and females are virtually identical in plumage. Some anecdotal reports suggest males might be slightly larger or have more prominent barring, but this is not consistently reliable for field identification.

Key field marks

• Plumage Pattern. Look for the fine, ladder-like black barring on the back, wings, and flanks against a predominantly green body. This is the most diagnostic feature.
• Underwing Patch. Observe the distinct black patch on the lesser underwing coverts, visible when the bird is in flight or stretching its wings. This is a reliable field mark.
• Size and Shape. Note its small, stocky build and relatively short tail, characteristic of the Bolborhynchus genus.
• Vocalizations. Listen for its soft, chattering calls, which are much quieter and less harsh than many other parrot species. This can help distinguish it in dense forest.
• Habitat and Elevation. Consider the habitat (humid montane forest) and elevation range (800-2,500m). This helps narrow down possibilities, especially when distinguishing from similar species with restricted ranges.
