Southern Lapwing Chick

About

The Southern Lapwing chick is the juvenile stage of the Southern Lapwing, a widespread and conspicuous wader in South America. Chicks are precocial, meaning they are relatively mature and mobile from birth, able to feed themselves shortly after hatching. They are characterized by cryptic downy plumage, designed for camouflage against predators.

Size & lifespan

Length

Approximately 10-15 cm (at hatching)

Wingspan

Not applicable for chicks (wings are undeveloped)

Weight

Approximately 20-30 g (at hatching)

Lifespan

Not applicable for chick stage; adult lifespan is typically 8-10 years in the wild.

Diet

Insectivore (primarily small invertebrates)

Physical characteristics

Plumage

Chicks are covered in dense, soft down. The dorsal side is typically mottled with shades of buff, brown, and black, providing excellent camouflage. The ventral side is usually paler, often whitish or light buff. They often have a dark stripe running from the crown down the back, and sometimes a dark eye-stripe.

Beak shape

Short, straight, and dark grey to black, proportionally smaller than adults.

Eye color

Dark brown, relatively large for their head size.

Leg color

Pale grey to yellowish-grey, becoming darker and reddish-pink in adults.

Distinguishing features

Cryptic downy plumage, relatively long legs for a chick, and a small, dark bill. They lack the prominent crest and facial markings of adults, as well as the carpal spurs.

Juvenile appearance

After the downy chick stage, juveniles develop a plumage similar to adults but duller, with less defined markings, a shorter crest, and often lacking the prominent carpal spurs or having them in a rudimentary form. The black areas of the adult plumage are often replaced by dusky brown in juveniles.

Seasonal changes

No seasonal plumage changes in chicks; their plumage is solely for camouflage during their vulnerable early life stage.

Sexual dimorphism

Not discernible in chicks.

How to identify

1. 1

   Size and Shape

   Very small, downy, and round-bodied with relatively long legs for its size. Lacks the adult's prominent crest and carpal spurs.

2. 2

   Plumage

   Cryptic mottled brown, buff, and black down on the back, with a paler belly. This camouflage makes them very difficult to spot against the ground.

3. 3

   Behavior

   Often seen scurrying quickly through short grass, staying close to adult Southern Lapwings who are usually very vocal and aggressive in their defense. They will freeze in place when alarmed.

4. 4

   Location

   Found on open ground, often in pastures, fields, or lawns, always accompanied by at least one adult.

Habitat & range

Biomes

Grasslands, pastures, agricultural fields, open wetlands, savannas, and urban parks.

Geographic range

Widely distributed across South America, from northern Colombia and Venezuela south through Brazil, Uruguay, Paraguay, Bolivia, Argentina, and Chile. Also found on Trinidad and Tobago.

Elevation range

Sea level up to approximately 3,000 meters (9,800 feet) in some Andean regions.

Preferred environments

Open, short-grass areas, often near water sources. They prefer disturbed habitats such as cultivated lands, airports, and urban green spaces, which provide good visibility for predator detection and access to invertebrate prey.

Behavior

Activity time

Diurnal. Chicks are active during daylight hours, foraging and resting under parental supervision.

Feeding habits

Chicks forage independently shortly after hatching, pecking at small insects and other invertebrates found on the ground. They primarily eat ants, beetles, grasshoppers, and other small arthropods. Parents often lead them to suitable foraging areas.

Social behavior

Chicks stay close to their parents, who are highly protective. They are part of a family unit until fledging. Adults are often seen in pairs or small family groups, sometimes forming larger flocks outside the breeding season.

Flight pattern

Chicks are flightless. Adults have a distinctive, somewhat erratic flight with deep wing beats, often accompanied by loud calls.

Migration pattern

Chicks are non-migratory. Adult Southern Lapwings are largely resident throughout their range, though some southern populations may undertake short-distance altitudinal or latitudinal movements during winter.

Territoriality

Chicks are not territorial. Adult Southern Lapwings are highly territorial, especially during the breeding season, aggressively defending their nesting and foraging areas from intruders, including much larger birds and mammals.

Breeding & reproduction

Breeding season

Varies geographically, typically during the local spring and summer. For example, in Argentina, it's August-January; in Brazil, September-March.

Nesting habits

Chicks are born in a simple scrape on the ground, often in open areas with short vegetation. The nest is typically unlined or sparsely lined with grass, pebbles, or small twigs. Parents choose sites with good visibility to detect predators.

Clutch size

Not applicable for chicks. Typically 2-4 eggs per clutch.

Egg description

Not applicable for chicks. Adult females lay 2-4 eggs, typically olive-brown to greenish-brown, heavily spotted and blotched with dark brown or black, providing excellent camouflage.

Incubation period

Not applicable for chicks. Incubation period for eggs is 28-30 days, primarily by the female, though the male may assist.

Fledging period

Chicks are precocial and leave the nest scrape within hours of hatching. They are able to fly and become independent at approximately 30-35 days old.

Parental care

Both parents are highly involved in caring for the chicks. They lead them to foraging areas, brood them for warmth and protection, and aggressively defend them from predators. Parents will perform distraction displays (e.g., 'broken-wing' display) to lure predators away from the chicks.

Where to find

Field tips

1. Look for Adults First. Southern Lapwing chicks are incredibly well-camouflaged. The easiest way to find them is to first locate agitated adult Southern Lapwings, as they will be very vocal and defensive if chicks are nearby. Watch where the adults are focusing their attention or defending.
2. Scan Open Ground Carefully. Once you suspect chicks are present, scan the ground very slowly and meticulously. Chicks will often freeze when they perceive danger, blending perfectly with their surroundings. Look for any slight movement or an unusual 'clump' on the ground.
3. Observe Parental Behavior. Adults may perform distraction displays (e.g., feigning injury) to draw attention away from their young. If you see this, it's a strong indicator that chicks are hidden nearby.
4. Use Binoculars. Even at close range, binoculars are essential for spotting these tiny, camouflaged chicks.
5. Maintain Distance. To avoid stressing the parents and chicks, always observe from a respectful distance. Approaching too closely can cause parents to abandon the chicks or expose them to predators.

Quick facts

Parents are fiercely protective, using loud calls and aggressive displays.

Diet:

Primarily small insects and invertebrates.

Habitat:

Open grassy areas, often near water.

Fun facts

• Southern Lapwing chicks are masters of disguise; their mottled down makes them almost invisible against a background of dry grass and soil.
• Despite their small size, these chicks are incredibly active and can run surprisingly fast to escape danger or follow their parents.
• The aggressive defense by adult Southern Lapwings, including dive-bombing and loud calls, is primarily to protect their vulnerable chicks from predators.
