1. GULLS
(pict taken from Gpedia.com)
Gulls are very familiar birds with
different species found in a range of habitats worldwide.
All gulls belong to the Laridae bird family, along with
terns, kittiwakes, skimmers, and noddies. There are approximately 50 species of
gulls found throughout the world, depending on how different species
classifications are split or lumped
At least one
gull species is found on every continent, including Antarctica, and many gulls
have widespread ranges that make them familiar to birders from vastly different
regions. This makes gulls one of the most widespread families of birds in the
world
Despite the
universal use of the general term "seagull" these birds are not
associated just with pelagic, marine, or coastal
environments, and in fact, there are no birds officially named seagulls. Many
gulls thrive in inland habitats, and they are often
found in wetlands, agricultural fields, parking lots, or even in urban and
suburban areas hundreds or thousands of miles from the coast. Gulls are not
usually found in the densest jungles, steepest mountains, or most barren
deserts, however.
Gulls
are omnivorous and eat a wide
variety of foods, including fish, insects, carrion, eggs, trash,
mollusks, and more. They are opportunistic feeders and will try just about any
type of food, even raiding picnic areas and landfills for scraps.
2. HUMMINGBIRDS

Hummingbirds are
small birds of
the family Trochilidae.They are among the smallest of birds: most species measure
7.5–13 cm (3–5 in). The smallest living bird species is the
2–5 cm Bee Hummingbird. They can hover in mid-air by
rapidly flapping their wings 12–80 times per second (depending on the species).
They are also the only group of birds able to fly backwards. Their rapid
wing beats do actually hum. They can fly at speeds over 15 m/s (54 km/h,
34 mi/h).
Hummingbirds help flowers to pollinate, though most insects
are best known for doing so. The hummingbird enjoys nectar, like the butterfly
and other flower-loving insects, such as bees. Hummingbirds do not have a good
sense of smell; instead, they are attracted to color,
especially the color red. Unlike the butterfly, the hummingbird hovers over the
flower as it drinks nectar from it, like a moth.
When it does so, it flaps its wings very
quickly to stay in one place, which makes it look like a blur and also beats so
fast it makes a humming sound. A hummingbird sometimes puts its whole head into
the flower to drink the nectar properly. When it takes its head back out, its
head is covered with yellow pollen, so that when it moves to another flower,
it can pollinate. Or sometimes it may pollinate with its beak.
Like bees, hummingbirds can assess the
amount of sugar in the nectar they eat. They reject flowers whose nectar has
less than 10% sugar. Nectar is a poor source of nutrients,
so hummingbirds meet their needs for protein, amino acids, vitamins, minerals,
etc. by preying on insects and spiders
3. WOODPECKERS
(pict. taken from ebird.org)
Woodpeckers are colorful and beautiful birds,
well-known for pecking the wood of trees with their pointed beaks.There are
about 200 different species of woodpeckers worldwide.
They live in
every place in the world except Australia, New Guinea, New Zealand, Madagascar, and the
extreme polar regions.Most species live in forests or woodland habitats,
although a few species are known to live in treeless areas, such as rocky
hillsides and deserts.
The most common plumage colors for
all woodpeckers are black, white, red and yellow. A few species also have
orange, green, brown, maroon and gold in their coloration. Brighter colors are
usually flashy patches, typically on the head, neck or back where they will be
easily seen. Woodpeckers have strong bills for
drilling and drumming on trees and long sticky tongues for
extracting food.
The tongue of a
woodpecker is up to 10 centimeters (4 inches) long and three times the length
of its bill. Many woodpeckers have barbed tongues that help them extract bugs
from trees and holes. When the long tongue is not in use, the woodpecker wraps
it around the back of its head, between the skull and the skin. The diet of
woodpeckers consists mainly of insects and their grubs taken from living and dead trees, and
other arthropods, along with fruit, nuts and sap from
live trees.
Woodpeckers
are monogamous. Both male and
female prepare nest in the tree. Female lays between 2 and 5 eggs. Incubation period lasts 11 to 14 days. It takes about 18–30
days before the young are ready to leave the nest. The main
predators of the woodpecker include wild cats, foxes, coyotes, snakes and large birds although many other species of animal
will prey on the woodpecker too
4. PEACOCK
(Pict taken from. pinterest.com)
The term “peacock” is commonly used to refer to birds of both
sexes. Technically, only males are peacocks. Females are peahens, and together,
they are called peafowl.Peafowl are members of the pheasant family.
There are 3 peafowl species; two Asiatic species and one African
species.The Indian
peafowl or blue peafowl (Pavo cristatus) originally
of India and
Sri Lanka, the green peafowl (Pavo muticus) of
Myanmar, Indochina, and Java and the Congo peafowl (Afropavo congensis) native
to the Congo Basin.
Their natural habitat is the forest or rain forest.Peafowl can live in
the wild for up to 20 years. Domesticated peafowl have been known to live as
long as 40 to 50 years. eacocks are a larger sized
bird with a length from bill to tail of 140 to 160 cm (55 to
63 in) and to
the end of a fully grown tail as much as 180 to 250 cm (70
to 98 in) and weigh 3.8–6 kg (8–13 lb). The females, or
peahens, are smaller at 90-110 cm (35-43
in) in length and weigh 2.8–4 kg (6–8.8
lb).
The peacock has some of the brightest feathers and one of the most
impressive courting displays of any bird in the world.Peacocks
have a top running
speed of around 16 km/h (10 mph). Peafowl are omnivores and
eat mostly plant parts, flower petals, seed heads, insects and
other arthropods, reptiles,
and amphibians
Peafowl are social birds. It’s typically only older peacocks that stay
by themselves. They sleep in large groups in tall trees, which is called
roosting, to protect themselves from other animals. They make shrieking sounds
to alert each other of danger.

5. THE BIRDS OF PARADISE
(Pict. taken from jakartaglobe.id)
The birds of paradise are
members of the family Paradisaeidae of the order Passeriformes. The majority of species are found in
eastern Indonesia, Papua New Guinea ,
and eastern Australia. Their habitats are: rain forests and mid-montane forests,
with a few species found in open savannas. There are an estimated 42 species of bird of paradise. The lifespan is unknown in the wild and up to 30 years in zoos.
Size varies depending on species, from the king bird of
paradise at approximately 15 centimeters (5.9
inches) to the black sicklebill at 110 centimeters (43
inches).Most species are distinguished by striking colors and bright plumage of
yellow, blue, scarlet, and green. These colors distinguish them as some of the
world’s most dramatic and attractive birds
The feeding habits of birds of
paradise are not well known, but it is believed that most species are fruit eaters. Most birds of
paradise also eat insects; they have been
observed tearing apart dead wood to get to insects. Some species have been seen
eating seeds, frogs and reptiles. Birds-of-paradise
build their nests from soft materials, such as leaves, ferns, and vine
tendrils, typically placed in a tree fork
Little
is known of wild bird of paradise behavior, but it is thought that natural predators include hawks and snakes. Eggs and chicks are the most vulnerable to attack. Hunting for plumes and habitat destruction have reduced some species to
endangered status; habitat destruction due to deforestation is now the
predominant threat.
