How to identify the Pacific Parrotlet

To correctly identify the Pacific Parrotlet (Forpus coelestis), 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 bright green plumage. Males have a distinctive cobalt-blue streak behind the eye, blue primary and secondary coverts, and blue on the rump. Females are entirely green, sometimes with a faint yellowish wash on the face and underparts, and lack the blue markings.

2. 2

   Beak shape

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

   Small, hooked, and strong beak, typically horn-colored or pale pinkish-grey.

3. 3

   Eye color

   Iris color and any distinctive eye markings.

   Dark brown with a narrow, pale periophthalmic ring.

4. 4

   Leg color

   Leg and foot color.

   Greyish-pink to grey.

5. 5

   Distinguishing features

   Standout features that separate this species.

   Its small size, stocky build, and the male's striking blue markings are key. The short, pointed tail is also characteristic of parrotlets.

6. 6

   Juvenile appearance

   How young birds differ from adults.

   Juveniles resemble adult females, being entirely green. Young males gradually develop their blue markings, which may be duller or less extensive than adult males.

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.

   Pronounced. Males have extensive blue markings (post-ocular streak, wing coverts, rump). Females lack these blue markings and are entirely green, sometimes with a slightly paler or yellowish face.

Key field marks

• Size and Shape. Look for a very small, stocky parrot with a short, pointed tail. Its compact build is distinctive among parrots.
• Male Plumage. Observe for bright green overall plumage with striking cobalt-blue markings: a streak behind the eye, blue on the primary and secondary wing coverts, and a blue rump. These blue patches are diagnostic for males.
• Female Plumage. Females are entirely green, sometimes with a subtle yellowish tint on the face or underparts, but crucially lack any blue markings. Their uniform green color distinguishes them from males.
• Vocalizations. Listen for their characteristic sharp, high-pitched 'chit-chit' or 'tsit-tsit' calls, often given in rapid succession, especially in flight or when disturbed. These calls are a good indicator of their presence.
• Flight Pattern. Note their fast, direct, and somewhat undulating flight with rapid wing beats. They often fly in small, tight flocks.
