What is Teal?
A teal belongs to one of the 15 small ducks that emerge from the family of Anatidae. Commonly, teals are found on many islands besides six chief continents. You will easily find teals in gravel pits, reservoirs, and flooded meadows in winter. People get amazed when they watch flocks of teals in a winter sky. Primarily, teals are herbivorous though animal foods might include 25 percent of some species' diet like the blue-wing. In some species, flocks of teals take off as groups, and they also change their directions united.
Most teals are Baltic or Siberian cold climes. In summer, teals breed in little numbers in the United Kingdom, commonly in the north. Male teals are grey, and they have black-and-yellow tails and speckled breasts, whereas females are recognized as mottled brown. However, both sexes demonstrate bright green wing patches in flight.
Teals are social creatures, and they habitually join mixed flocks that comprise several dabbling ducks, like widgeons, mallards, and northern shovelers. Teals join several teal species too.
Variations of Teals
Some teals are well known as game birds, and the best among them are the Holarctic green-winged teals (A.crecca). These birds are 13-15 inches or 33-38 centimeters. Holarctic green-winged teals are found in thick flocks. Small blue-winged teals (A. discors) breed across the northern US, Winters South of the United States, and Canada.
You will find cinnamon teals (A. cyanoptera) in North America, and they are deep-colored reddish birds that have blue wing patches. African Hottentot teals (A. punctata) are pretty tame, and they remain immobile amongst vegetation even when they hear the firing of shots close to their places.
What are Common Teals?
A common teal or Eurasian teal is a widespread duck that breeds in temperate Euro siberia. They migrate south in winter. These teals are gregarious ducks, and they form huge flocks. Commonly, they are found in feeds on aquatic invertebrates and seeds and sheltered wetlands.
Description of Common Teals
A common teal is the smallest existing dabbling duck that is found in a length of 7.9-11.8 inches. The male teals weigh around 340 g, and the females weigh 320 g. The wings happen to be 6.9-8.0 inches long, and they yield a wingspan of 21-23 inches. The bill measures 1.3-1.6 inches in length, whereas the tarsus happens to be 1.1-1.3 inches.
When you watch a drake in nuptial plumage from a distance, then it will appear grey, a yellowish behind, a white stripe, and a dark head that runs along the flanks. The upper neck and head of the drakes are chestnuts, and there are shimmering dark green patches of a teardrop- and half-moon shape that begins fast before the eye. After this, they arc to the higher hindneck.
What are Teal Ducks?
Teal ducks are small freshwater dabbling ducks, and you will find their different species that share similar traits that comprise their habitat preferences, feeding behavior, proportions of their body, petite size, and exclusive coloration. Most often, novice and professional borders utilize various identifiers for cluing themselves into the kind of duck they spot at the time when the birds watch.
Where are Teals Found?
Normally, a teal is found in shallow freshwater places, and its chosen habitats comprise rivers, ponds, swamps, marshes, ponds, flooded agricultural fields, and also riparian zones that have ideal shelter and vegetation. A teal duck is the most prevalent duck species, and you will find some varieties of teal on all the continents except Antarctica.
Physical Features of Teals
Teal ducks are characterized by short tails and stout necks, and they emerge as smaller in comparison to other kinds of ducks. Though similar in stature and size, both female and male teals look remarkably different in various identifiable manners. The male teals boast of characteristic plumage that comprises unusual patches or swathes on the face, wings, or head. On the other hand, female teals happen to be highly camouflaged, and they habitually spot mottled patterns and earthly tone colors. They act as protection to these birds when they care for or nest their young ducklings.
Breeding and Diet of Teals
The season of breeding of teals begins from April, and it lasts till May. Pairs of teals form in winter, and they travel to the breeding ground together in March. Their nests tend to be hollow, and they are lined with down feathers and leaves in thick vegetation closer to water. Usually, clutches are 8-11 eggs, and they are incubated for nearly 23 days. The young ones continue to remain with their mothers for nearly 25-30 days before they fledge.
A teal eats insects, larvae, crustaceans, and invertebrates. In winter, they feed on seeds of a few aquatic plants and grasses. They feed during the daytime while breeding and eat at twilight. At times, teals eat mollusks and insects, especially at the time of nesting season, and during this time, ducklings need sufficient protein for adequate growth and development.
The Reproductive Habit of Teals
A blue-winged teal bird has only one mate at the time of breeding, though these birds change mates in-between breeding seasons. Males do courtship displays for enticing females. The process of courtship starts in flight, and during this time, males call as well as pursue females. The usual display happens like this: the males swim in front of females, and their bodies happen to be at a particular angle to them, and their heads point away. The female teal bird stretches its head outward, and it shows it has accepted the male. After this, the female teal bird lowers its head and points its bill towards the male. Towards the end, both of them dip their heads.
The blue-winged teals nest from the end of April through the beginning of May, and they breed in some wetland areas that are within shallow marshes, grasslands, temporary ponds, flooded ditches, and sloughs. A female teal lays 6-14 eggs, and it takes somewhere between 21 and 40 days for hatching. The young ones reach the stage of fledgling at nearly 24 days, and they become free after forty days.
The female teals take charge of the maintenance of the nest, and they also lead the young ones, though males never help them in this job. Females also take charge of making nests, and they do this by digging bowl-shaped depressions, and they also pull in dried grass. They lay only one egg every day and, at times, ten or over ten eggs. At the time of the hatching of the eggs, the females clean their hatchlings and make them clean and dry. After this, they lead their young ones to a close wetland and don't get back to the nest. The ducklings stay with their mothers till the time they do not become prepared to fly, and it happens after 40 days of hatching.
The Species of Teal Duck
Every teal is found in the technical genus Anas, and it hails from the family Anatidae besides other geese, swans, and ducks. There are presently over twenty species of teal that are found throughout the world, although there is a possibility that similar species of dabbling duck might be reclassified or various teals that could be lumped or split into extra species in the forthcoming days. So, they change the number of exclusive species of teals.
In several areas where just one species of teal predominates, the birds might be known as teal in place of their full names. Sometimes, the common names of teals confuse the birders who have many listing choices or those who do travel to various areas to watch various teal species.
Keeping Teals in Custody
People prefer to keep a few teal ducks in the form of domestic waterfowls either at various agricultural operations or in private collections. Sometimes, teals are harvested too for game hunting or food. People see these teals in different botanical garden settings, zoos, or aviaries. The captive teals do escape occasionally, and they propose unexpected sightings in some places that happen to be far from the common range of species.
The Behavior of Blue-Winged Teals
Blue-winged teals happen to be highly social, but their behavior changes at the time of breeding when females and males migrate to nesting places. They also migrate between breeding and wintering ranges every year, and they happen to be hugely active all through the day. The teals are also capable of walking well in shallow water and on land. They habitually preen on rocks and logs that are a little above water. The blue-winged teals gain flight from water or land directly. They dive in the water only when they attempt to get rid of other ducks or get frightened by a predator.
The Nesting Pattern of Green-Winged Teals
Green-winged teals line their nests with down weeds, leaves, and grass. Most often, the females cover the eggs with down to keep them warm at the time when they leave the nest. The female green-winged teals are capable of incubating the eggs. The hatching process of chicks takes about 21-23 days. The males leave the females as soon as they incubate. The females lead the chicks to the water when they become only one day old. However, they fledge only when they become one month old. The female green-winged teals appear to be highly aggressive when they defend their chicks. Most often, the female green-winged teals work collectively to shield broods from some predators, such as crows and skunks.

Teals are small ducks that turn in unison and happen to be swift in flight. Seemingly, the blue-winged teals do not remain present in major parts of North America. Their nest site remains on the ground of coastal meadow, hayfield, and prairie. Teals form pairs in early winter, and this process continues at the time of spring migration too. The male teals have different courtship displays, and they comprise one where the entire forepart of their bodies remains submerged and tail raised. Their feet also waive in the air. The nests of teals happen to be a shallow depression where some weeds and grass are included, and they are lined with down. They remain concealed well with surrounding vegetation too.
FAQs on Teal
1. How Do Teals Communicate With One Another?
Ans: The male blue-winged teals make some sets of sounds, and they allure females. The sounds comprise lower-pitched nasal "pay" and higher-pitched whistle-like "peew." A female teal also uses louder quacks at the time of the breeding season for communicating with their young and mates too.
2. How Do Teals act as Game Birds?
Ans: Professional sportsmen habitually hunt teal ducks, and when they hunt teal, they end up minimizing the issue of overpopulation. This permits the more agile, smarter, and stronger ducks to live and also reproduce. It finally strengthens the general species' health. Some specifics such as the precise length of a hunting season, the number of teals that a hunter might harvest, and where these birds can be lawfully hunted do vary a lot based on the local teal population's strength. Nonetheless, hunting confinements are habitually adjusted every year, formed on the changes of the breeding population from one season to another. In a few years, teals are not hunted at all due to some legal issues.
3. For How Long Do Teals Live?
Ans: The majority of the blue-winged teal ducklings fail to survive through their initial few years as they get diseases and parasites. Avian cholera or Pasteurella multocida or Botulism or Clostridium botulinum are both bacterial diseases, and they kill countless blue-winged teals as they remain present in water. However, the blue-winged teals that manage to survive till their adulthood survive up to 17 long years.
4. Are Teals an Endangered Species?
Ans: The blue-winged teals, though not rare, get protection from the Migratory Bird Act. Teals get hunted all through their range though hunting is commonly regulated. The population of blue-winged teals gets harmed by pesticides, like dieldrin and they, at times, get trapped in some plastic trash. Sometimes, cars also hit them, and at times, they get entangled in fences, various human structures, and power lines. Due to the destruction of wetlands, the population of blue-winged teals has decreased remarkably in recent years.
