How to identify the Shorebird Chick (Likely Sandpiper or Plover)

To correctly identify the Shorebird Chick (Likely Sandpiper or Plover) (Varies depending on species (e.g., Calidris alba, Pluvialis squatarola)), 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

Varies greatly by species, typically 5-15 cm

Wingspan

Wings are undeveloped at hatching, not measurable in the same way as adults. Adult wingspan varies from 20-60 cm.

Weight

Varies greatly by species, typically 5-50 g at hatching

Physical features to check

1. 1

   Plumage

   Overall feather coloration and pattern.

   Downy, cryptically patterned with shades of brown, grey, black, and white. Patterns often include stripes, spots, or mottling on the back and crown, with paler underparts. The specific patterns are crucial for species identification.

2. 2

   Beak shape

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

   Short to medium-length, straight or slightly decurved/recurved, depending on species. Often proportionally shorter and thicker than adult bills.

3. 3

   Eye color

   Iris color and any distinctive eye markings.

   Dark brown, often appearing large relative to the head size.

4. 4

   Leg color

   Leg and foot color.

   Typically dark (grey, black) or pale (yellowish, greenish), often duller than adult leg coloration.

5. 5

   Distinguishing features

   Standout features that separate this species.

   Precocial nature, downy plumage, cryptic coloration, relatively large eyes, short bill, and often disproportionately long legs for their body size. Specific patterns of down, leg color, and bill shape are key for species identification.

6. 6

   Juvenile appearance

   How young birds differ from adults.

   Chicks are covered in down. After fledging, they develop juvenile plumage which is typically duller and more cryptically patterned than adult breeding plumage, often resembling adult non-breeding plumage but with more distinct feather edgings or streaking.

7. 7

   Seasonal changes

   Plumage variation between breeding and non-breeding seasons.

   Chicks are only present during the breeding season. Their appearance changes as they grow, transitioning from downy chick to juvenile plumage, then to adult non-breeding and eventually breeding plumage over subsequent seasons.

8. 8

   Sexual dimorphism

   How males and females differ.

   None apparent in chicks.

Key field marks

• Downy Plumage Pattern. Observe the specific patterns of stripes, spots, and mottling on the chick's back, crown, and sides. These patterns are often species-specific and serve as camouflage.
• Bill Shape and Length. Note the relative length and shape of the bill (straight, slightly decurved, or recurved). While shorter than adults, the general shape can hint at the species.
• Leg Color. Observe the color of the legs and feet. This can range from dark grey/black to yellowish or greenish, and can be a distinguishing feature.
• Behavior and Habitat. Consider the chick's behavior (e.g., foraging style, interaction with parents) and the specific habitat it is found in. This context can narrow down potential species.
• Parental Association. The most reliable way to identify a shorebird chick is to identify its parents. Observe which adult birds are attending to the chick, as they will be of the same species.
