All The Facts & Info You Need To Know About Lesser Scaup
Despite being a non-migratory species, scaup numbers fluctuate significantly, and they tend to congregate in sheltered areas.
This is because they can be fliers, so their movement is primarily dictated by wind and ice conditions during the winter.
In the 1990s, the New Zealand scaup population was estimated at around 20,000 birds, though this may have increased as their range expanded to Canterbury and other regions.
Lesser Scaup
A little-known fact about Lesser Scaup is that they breed in Canada and the United States, and can be found in all types of water.
In fact, they are often found breeding on hayfields and prairies. When not breeding, you can find them in ponds, lakes, and streams.
Facts about Lesser Scaup include where they live, where they can be seen, and where they breed. This scaup breeds in lakes, reservoirs, and large marshes.
In the winter, they spend their time mainly on freshwater lakes. They often overlap with their larger cousins.
The average number of Lesser Scaups per nest is eight to nine, so it’s easy to spot them in the wild. But what you need to know about the breeding habits of Lesser Scaup is the species’ behavior in different environments.
Female Lesser Scaups spend most of their time on breeding sites. During migration, the species lags behind other waterfowl.
In fact, they can stay on breeding grounds until the water freezes, and that makes them one of the last species to migrate north from their wintering grounds.
The breeding population of this species is estimated to be at 3.8 million.
Pateke
The New Zealand scaup (papango) is a diving duck that lives in lakes in New Zealand.
Its black body and striking yellow eyes make it look like a bath-toy duck. In breeding season, females display a white face patch.
They also have a black wing bar when flying. These ducks are endemic to New Zealand and are protected under the country’s conservation laws.
In recent decades, New Zealand’s scaup population has decreased due to human settlements in the country, but some regions are beginning to see a rebound.
In urban areas, this species has been helped by the planting of low-hanging vegetation along waterways.
Though they’re not migratory, the New Zealand scaup is considered a threatened species and has been fully protected since 1935.
Its numbers fluctuate from year to year, but the total population of the species is estimated at around 20,000 birds. A New Zealand scaup’s appearance is dark and rounded.
It’s similar to that of a cork, allowing it to float for a long time. Despite their small size, the scaup is one of the most versatile duck species, capable of swimming several meters underwater and resting on land. Its large bill allows it to float on water, but its bill is covered with feathers.
Grey Teal
The Grey teal, also known as the Black Teal, is a small, endemic duck from New Zealand.
It lives primarily in freshwater lakes. It is also known as a Papango by Maori. It has a black, rounded body, striking yellow eyes, and iridescent plumage.
In flight, its long, curved wing bar is white, which makes it look like a cork. The grey teal is a mottled brown duck with white and green flashes on its wings.
Its calls are often heard at night, with the male giving a soft preep and the female a loud quack. It is a relative of the black teal, which is also found in New Zealand’s clear lakes.
Other names for this duck include matapouri, titiporangi, and raipo. The grey teal is found throughout New Zealand, but its population is still relatively low, with an estimated 20,000 birds.
Although there are no official statistics regarding the number of grey teals in New Zealand, the bird’s conservation status is Least Concern.
The grey teal lives in coastal lagoons and freshwater lakes. In addition, it is rarely seen on the Chatham Islands and Stewart Island.
Australasian Shoveler
The Australasian Shoveler is a species of duck that lives in the swamps of Australasia.
During the breeding season, the birds have a mottled brown body, with white patches and black bars on the back and shoulders.
Their bills are made of fine hairs, which are used to strain the water. During the breeding season, the males molt to dull brown feathers.
After breeding, the females care for the brood for about eight weeks. Young birds grow to be fully grown in one to two years.
The Australasian Shoveler is a rare visitor to Brisbane, where it is found on rare occasions. Its distinct plumage makes it easy to spot, especially in the breeding season.
Eclipse males, however, have duller plumage. The species is not globally threatened but is still at risk of decline due to water pollution and other human activities.
Fortunately, the Australasian Shoveler has many friends in its habitat, including the zoos, despite its limited numbers.
Weight
The New Zealand scaup weighs about twenty-five pounds (610 grams) and the female a little less, at about twenty-five ounces.
This is five times more than the Guam rail! Although there is no specific male or female New Zealand scaup name, it is usually known as a chick, and they start feeding shortly after birth.
The female tends to feed more than the male, however, and this is the main reason for aggressive disputes among rivals.
The male and female scaups look nearly identical in the field, although there are subtle differences in their appearance.
In the male, the iris of the eye becomes yellow when it is about twelve weeks old. Both sexes have a broad white bar on the upper wing and white underwing.
They fly swiftly and often hover above the water. They may rest on land for short periods, but will quickly return to the water if disturbed.
Habitat
The New Zealand scaup, also known as black teal, is an endemic bird of the South Pacific.
Other names for this bird include matapouri, titiporangi, raipo, and papango. Its habitat is primarily marine, in areas with plenty of food.
The scaup’s occurrence is highly dependent on its food sources. In New Zealand, it is found in many marine areas, mainly coastal waters.
The scaup’s preferred lakes vary from year to year. The birds congregate in sheltered areas and move as wind conditions change.
While the New Zealand scaup is a non-migratory species, it can vary widely in population numbers, and their numbers fluctuate greatly.
The species’ population is estimated to be around 20,000 in the 1990s but may have increased due to range expansion in Canterbury.
The habitat of the New Zealand scaup includes freshwater lakes and coastal lagoons. The male scaups have a blue-grey beak with a black tip, and dark brown flanks and underparts.
Female scaups are distinctly lighter brown, with a white patch around their beak. The scaup’s habitat includes sheltered waters and lakes that are not disturbed by humans.
Whistles
The Whistles of New Zealand scup are distinctive calls of the scaup bird. Males make a high-pitched whistle, while females make a low-pitched whistle.
The New Zealand scaup is found on both the North and South Islands and in lakes, waterways, hydroelectric facilities, and inland bodies of water.
These birds are nocturnal and feed only at night. The population of these birds is estimated at approximately 3,300-6,700 mature individuals and is increasing.
Their population status is considered Least Concern, and they are not threatened. The scaup weighs up to 1.4 kilograms and breeds in boreal forests and tundra.
They nest in isolated islands in northern lakes, and the males attract females with soft whistles. The females respond to these whistles with raspy vocalizations.
They form monogamous pairs, and the males leave after the females lay their eggs.
The young scaups can walk almost instantly. The birds are threatened by pollution and other humans, which destroy their habitats and eat their eggs.
Diet
The diet of New Zealand scaup differed between the two winters, 2016-2017 and 2017-2018.
The major differences were found in the proportion of Chironomidae and Polygonum seeds, with the latter comprising almost a quarter of the dissimilarity between the two diets.
Although a similar percentage of fish was also found, the proportion of Polygonum seeds was higher in winters 2016-2017 than in winters 2017-2018.
The diet of the New Zealand scaup is a complex mix of aquatic plants, invertebrates, and insects.
They dive up to two meters in depth and remain underwater for fifteen to 40 seconds. When feeding, their bill sticks into the water and catches aquatic insects.
They prefer to forage in deep freshwater bodies and avoid shallow wetlands. Males are vocal and often perform courtship displays with a high-pitched whistle.
The diet of the New Zealand scaup consists primarily of aquatic plants and animals, as well as small fish and water snails. They also eat mussels and mollusks.
The New Zealand scaup can dive quite deep, spending up to 20 seconds underwater to find food.
Its preference for water bodies makes this a desirable species for hobbyists and fishermen. Its dietary needs are also a key component of the species’ survival.
