What predators do hummingbirds have
humming-bird (Trochilidae) is a tiny bird, they are so small that they are known to have been captured by dragonflies and praying worshipers, trapped in spider webs, torn by frogs, and trapped in thistles.
The bright, shimmering colors of the feathers of many species (usually only for men) prompted the British naturalist John Gould of the XNUMX. Century to give exotic common names to many species of hummingbirds, many of which are still in use, for example, flirt, fairy, mountain star, wooden star, sapphire, topaz, sun gem and sylph.

All species of hummingbirds are small and many are tiny. Even the largest, the giant hummingbird (Patagona gigas) in western South America, is only about 20 cm long and weighs about 20 grams, less than that of most sparrows. The smallest species, the bee hummingbird (Mellisuga, sometimes Calypte, Helenae) from Cuba and the Isle of Pines, measures a little more than 5.5 cm, of which the beak and tail make up about half. Weighing around 2 g, this species is the smallest living bird and, together with the shrew, the smallest warm-blooded vertebrate.
They have compact, strongly muscular bodies and fairly long wings that, unlike the wings of other birds, only connect to the body from the shoulder joint. The architecture of the wing allows them to fly not only forward, but up and down to the sides and back, and fly in front of the flowers when they receive nectar and insects from them.
The speed at which a hummingbird flutters is the same during directional and hovering flight. It varies with the size of the bird. The bigger the bird, the lower the rate. As a result, the smallest have extremely fast wing beat rates. The Calliphlox amethystina, one of the smallest species, has a wing beat rate of approx. 80 per second; The larger woman flaps her wings at a rate of about 60 times per second. The giant hummingbird, for example, only flaps its wings about ten times per second. In fact, the largest hummingbirds appear to flap their wings more slowly than other birds of comparable size.
The body feathers are sparse and often heavily metallic and look quite creepy. The sexes look similar in some species, but differ in most species; Males of the latter species display a multitude of brilliance and ornamentation, surpassed only by birds of paradise and certain pheasants. The most typical badge is the gorget, a shimmering feather bib, the color of which depends on the viewing angle. Other specializations include ridges; shortened or thickened arrows on wing feathers; Spatula, wire, or flag-shaped tail feathers; and "pants", clumps of puffy feathers on the thighs (usually white).
The hummingbird's beak, which is adapted to provide the nectar of certain types of flowers, is usually quite long and always thin. In thorns (Ramphomicron and Chalcostigma) it is quite short, in hummingbirds with sword bills (Ensifera ensifera) it is unusually long and makes up more than half of the bird's 21 cm length. The calculation is slightly curved in many species, strong in sickle cell diseases (Eutoxeres); appears at the tip of the needle (avocado) and avocado (opisthoprora).
Most species that have been adequately studied do not show pairing. Pair bonds are formed in the purple ears (Colibrí) and some others, and both sexes assume parental responsibilities. In most other species, the male defends an area where females are exhibited in flight, passing with steps, strokes, and sudden stops and starts.
It is often placed in front of the female and oriented so that the light reflects the color of her twitter. Territorial males drive away hummingbirds of their own and other species, and immerse themselves in large birds such as crows and hawks, and even mammals, including humans.
Most hummingbirds, especially the smaller species, have squeaky, screeching, or squeaky songs. However, during their U-shaped exhibition flights, the wings often generate hum, hiss, or click that appear to function similarly to the songs of other birds. In many species it is the tail feathers that make the noise.
These birds live between trees, bushes and grapevines in their respective habitat. They are very territorial and keep a close eye on who else is within range. They will fight each other for food sources and living space.
They try to find a place to sleep where they can find shelter. Since these birds are small and have no real defense, they do their best to hide well from predators and other dangers. They are sometimes found asleep face down in pine trees. It is believed that this is just another way to blend in with their living space to stay hidden.
Experts believe that the hummingbird has an amazing memory. They are believed to have a pattern of where to go for groceries and around items in their niche. Some experts even say that the hummingbird can remember all of the flowers and plants it has been feeding on and how long it will be before it can feed on them again.
These birds are also quite territorial. They will fight each other to protect where they lived and where to find food. They seem to do reasonably well in captivity, but they also seem to thrive outdoors, where they can roam freely. Many places of captivity, such as B. Zoos, provide a beautiful forest area to find food and hide in the trees.
The distribution of hummingbirds is restricted to the New World, where the greatest diversity and number of species are found in South America. About 12 species occur regularly in the United States and Canada. Only the blond-throated hummingbird (Archilochus colubris) breeds in eastern North America, where it occurs from Nova Scotia to Florida. The northernmost hummingbird is the Rufous (Selasphorus rufus), which breeds from Southeast Alaska to Northern California. The broad-tailed hummingbird (S. platycercus) breed in the western United States and Central America, and Allen's hummingbird breeds in coastal regions of California.
The hummingbird's diet is mainly based on nectar from flowers, tree sap, insects, and pollen.
Fast breathing rate, fast heartbeat, and high body temperature require frequent eating. You also need a large amount of food each day. They have a long tongue that they use to lick their food at speeds of up to 13 licks per second.
The hummingbird feeds mainly on nectar.
While an adult hummingbird may not seem like a significant source of food to a human, it can be a quick and tasty snack to an animal predator.
Fat hummingbirds are full of sweet nectar and good sources of fat, especially in late summer and early fall when hummingbirds are fattening up for migration. Many predators will not think twice about hunting hummingbirds, such as wild or domestic cats, large insects such as praying mantis and web spiders, large snakes and lizards, large frogs and fish, poultry, birds of prey.
These predators often watch feeding areas like bird feeders or flower beds and wait until they are within range before striking. When feeding, they tend to focus on the food source rather than the threats around them, and those few moments of swallowing can put them at great risk from cunning predators.
The hummingbird nest is a small cup made of plant fiber, cobwebs, lichen, and moss attached to a branch, forked twig, large leaf, or ledge. In certain species known as hermits (Phaethornis), the nest is hung from a narrow stem at the bottom of a ledge or from the ceiling of a cave or passageway. The nesting cup, placed on one side of a mass of mud and plant matter, is held straight by carefully weighting the other side of the mass.
The two elliptical white eggs (rarely one) are the smallest that a bird lays, although proportionally they make up about 10 percent of the female's body weight. They incubate for about 15 to 20 days. The young, blind and practically naked, are fed by belching and flee in about three weeks; The time between laying and hatching appears to correlate with the food supply.
State of preservation
It is classified as an endangered animal. Historically, hummingbirds were killed for their feathers, but today they face different but equally devastating threats.
Habitat loss and destruction are the main threats to the hummingbird. Because they are often specifically adapted to each individual habitat, all hummingbird species currently listed as Endangered or Endangered on the IUCN Red List are threatened due to habitat destruction and loss.
Changes in land temperatures due to climate change affect the migration patterns of hummingbirds, causing different species to be seen in places outside of their normal range, where it can be more difficult for them to find food.
