Many bird species exhibit sexual dimorphism, i.e., male and female
have differing appearances which can be quite subtle.
In the case of the Red-necked Avocet the only way one can tell
male and female apart is by the length and shape of their bills.
The male, top, has a somewhat shorter and less extremely up-curved
bill than the female.

Breeding information |
| Breeding season: Aug - Dec | Eggs: 3 - 5 | Incubation period: 23 - 25 days | Fledging age: 28 - 35 days |
The breeding season depends significantly on geographical latitude. Given the right conditions, especially after good rain, they can breed any time of the year. Red-necked Avocets nest in small, loose colonies of up to ca. 150 pairs. One brood is raised per season.
| Nest building: ? | Incubation: Female & male | Dependent care: Female & male |
The young are "precocial", which means that they leave the nest almost immediately after every chick has hatched (which can be within hours of the last chick hatching). They follow their parents, who lead them away and show them how to feed themselves. The chicks do not return to the nest.

Nest |
"bungobittah", "lar", "malunna", "jindi" [bundjalung] = nest [Aboriginal] |
| Type: Scrape | Material: Bare soil, possibly a few twigs or plant debris | Height above ground: N/A |
The nest, usually a scrape with a minimum of material added to it, is usually camouflaged between plants such as samphire, small reeds or small shrubs.

Food, Diet |
Red-necked Avocets feed on small animals they sweep up from just under the mud surface of shallow waters.
This photo illustrates Red-necked Avocets' hunting technique; they
sweep their bills sideways, often vigorously, dredging through mud
in pursuit of small animals just under the surface

Here one can see how Red-necked Avocets sift water for prey; the upper
mandible is held steady while the lower mandible is moved up and down

Red-necked Avocets can feed at various depths, even with the
head completely under water
