Hummingbird Elegance

Topic	Information
The Smallest Birds	The weight of the Cuban bee hummingbird is a little 1.95 grams. One stamp might theoretically be used to mail sixteen letters first class. The fourth-smallest bird, the calliope hummingbird, is found in the mountains of western North America and weighs 2.5 grams.
The Tiniest Egg	The walnut-shell-sized cup made of plant material and spider webs holds the one or two pea-sized eggs in a ruby-throated hummingbird clutch.
The Avian Helicopter	Swifts and they have powerful wing flap strokes on both the upbeat and downbeat, which gives them exceptional flying agility. The only vertebrates that can continuously hover, fly backward, and fly upside-down are their.
Life in the Fast Lane	The heartbeat of a ruby-throated hummingbird ranges from 225 beats per minute while at rest to more than 1,200 beats per minute when in flight. In straight flight, wings beat roughly 70 times per second; during diving, they beat more than 200 times each second.
Asleep on the Job	To save energy, they enter a profound, sleep-like state known as torpor. This physiological condition keeps the body temperature extremely low and drastically reduces metabolic activity. Any night of the year, depending on the meal and temperature, tors is used.

Habitat

They are found only in the New World, from Tierra Del Fuego to southern Alaska, from subterranean deserts to steaming tropical forests at elevations of up to 16,000 feet in the Andes of South America. There are around 340 species of hummingbirds.

The majority of species are found in tropical regions, and although 17 species typically nest in the United States, many of them are found in close proximity to Mexico. One or two breeding species can be found in most parts of the United States, and only the ruby-throated hummingbird nests east of the Mississippi.

Particular personality characteristics and metabolism

Aspect	Details
Humming Duration	Hovering close to a feeder, a calliope hummingbird produces a humming sound by rapid wingbeats and vocalizations (12 seconds.0:12).
Wingbeats and Humming Sound	A humming sound produced by the aerodynamic forces created by fast wingbeats during flight and hovering. – Unusual among animals that can fly. – Has a musical instrument-like acoustic character.
Wingbeats Mechanism	Made possible by the pectoralis major and supracoracoideus muscles producing an elastic recoil of the wing strokes.
Vision	Small eyes that can accommodate things well. – Larger corneas, which make up 50% of the entire width of the eye, improve vision. – An exceptional 45,000 neurons per millimeter square of retinal ganglion cells for improved visual processing. An enlarged cornea makes it easier to fly at night. – Changes in the brain to enable better spatial resolution during flight. – A fourth color-sensitive visual cone is present in certain animals.
Vocalization and Hearing	A variety of vocalizations used in speech. – Learning vocal production to add diversity to songs. – A specialized syrinx with a wide frequency range for pitch adjustment. – Seven forebrain structures related to voice acquisition. – Some species can vocalize in ultrasonic frequencies.
Metabolism	The highest metabolism found in animals. – Ten times more oxygen consumed than world-class human athletes. – Effective usage of consumed carbohydrates to produce quick wingbeats. – Strong ability to oxidize fats and carbs. – Evolutionary adaption for carbohydrates to be oxidized directly.
Heat Dissipation	Specialized heat dissipation mechanisms. – Convective cooling, featherless regions, and evaporation all contribute to thermoregulation.
Kidney Function	Flexible renal function for changes in nectar mineral content. – Morphological modifications for accurate control of electrolyte and water balance.
Hemoglobin Adaptation	Adaptation of hemoglobin for life at high altitudes. – A higher affinity for binding oxygen at high elevations.
Adaptation to Winter	Northerners spending the winter in chilly climates. – Sugar’s transformation into fat in cold weather. – Growth in population as a result of invasive plants, bird feeders, and climate change.
Torpor	Torpor during the night to avoid energy loss. – A decrease in breathing, heart rate, and body temperature during torpor.
Lifespan	Durability despite a quick metabolism. – A three to five year lifespan is typical. – Records for longevity of 12 years or more.

Feeding

As specialized nectarivores, they are specially designed to extract nectar with efficiency. Their excellent hovering flight combined with their lengthy bills and tongues enable them to visit flowers quickly without perching. With their sophisticated digestive systems that enable them to absorb nearly

99% of the glucose from nectar in just a few minutes, they stand out as the only birds that predominantly rely on nectar for energy. Thousands of New World plant species have coevolved with hummingbirds, an important vertebrate pollinator. The association between certain plants and exclusive

their pollination is not as selective as previously believed. Several different species of their are necessary for pollinating even more inaccessible plants. Maximize their eating efficiency on flowers that correspond to their bill morphologies, even if they are not very choosy.

• They prefer specific flowering plants based on color, diurnality, and sucrose content.
• Commonly consumed plant genera include Castilleja, Centropogon, Costus, Delphinium, Heliconia, Hibiscus, Inga, and Mimulus.
• They may visit 1-2 thousand flowers daily to meet energy demands.
• Nectar lacks nutrients, leading hummingbirds to supplement their diet with invertebrates.
• Insectivory, though not calorically crucial, is essential for them, with some species being largely insectivorous at times.
• Common invertebrate food items include flies, spiders, Hymenopterans, and Hemipterans.
• Estimates for insectivory in the hummingbird diet vary from 5-15% of feeding time.
• Overall diet composition is approximately 90% nectar and 10% arthropods by mass.
• They show adaptability in feeding behavior based on factors like floral abundance.
• Despite their high metabolism, they spend the majority of their time sitting or perching, with feeding occupying around 20% of their activity.

They have a high metabolic rate, which makes them prone to famine and makes them very alert of food sources. In order to protect their future food sources, a number of animals in North America are ferociously protective of their feeders.

A larger hippocampus helps them with their spatial memory when mapping previously visited flowers during nectar foraging

Migration

Information
Migration Patterns and Numbers
Their migration is rather rare; about 12–15 of the 366 species that are known to migrate each year, mostly in North America, do so.
The tropical rainforest belt spanning Amazonia and Central America is home to the majority of hummingbirds, negating the need for migration.
Seasonal variations in food, temperature, competition, predators, and innate cues are all factors that affect migration.
North American Hummingbirds
The majority of them in North America fly southward for the winter, while certain species stay in particular areas all year round.
Examples are the buff-bellied hummingbird, which winters in South Texas and Arizona, and the Anna’s hummingbird, which is found in Arizona.
Throughout their migration, ruby-throated hummingbirds can be seen all the way to Atlantic Canada. They spend the winter in Mexico, South America, Texas, and Florida.
Many kinds of their can be seen in southern Louisiana in the winter.
Rufous Hummingbird’s Extensive Migration
Rufous hummingbird breeds in coastal British Columbia and Alaska, winters in southwestern US and Mexico.
large spring migration, nesting farther north than any other species, to the Yukon or southern Alaska.
Being cold hardy makes it possible to survive in subfreezing temperatures with enough food and shelter.
Longest Migratory Journey
One of the longest migratory flights is made by the rufous hummingbird, which travels 3,900 miles from Alaska to Mexico in one direction.
According to a body displacement calculation, this trip is equal to 78,470,000 body lengths.
In contrast to the 11,185 miles that the Arctic tern travels (65% of its body displacement during rufous hummingbird migration).
Time-Coordinated Migration along Pacific Flyway
The migration of rufous hummingbirds northward along the Pacific flyway may be synchronized with the blooming of springtime flowers and tree leaves, as well as the availability of insects.
A breeding opportunity may be impacted if one arrives at the nesting grounds before nectar is available.

Reproduction

Males don’t participate in nest building. On a tree or shrub limb, the majority of species construct a cup-shaped nest. Depending on the species, the nest can range in size from less than half the size of a walnut shell to several centimeters. Lichen and spider silk are used by several their species to anchor

and bind the nest materials together. As the fledgling grow, the nest can accommodate them thanks to the special qualities of the silk. Despite being the smallest of all bird eggs, the two white eggs that are laid are big in comparison to the adult hummingbird’s size.

14 to 23 days are needed for incubation, depending on the species, the surrounding climate, and how attentive the female is to the nest.The mother puts her bill into a fledgling’s open mouth to feed it small arthropods and insects, which

the chick then regurgitates into its crop.The mother bird may continue to nurse the chicks for an additional 25 days, but after 18 to 22 days, the swallows depart the nest to go on their own.

Communication

Courtship dives

• Male Anna’s hummingbirds soar 35 m above females before falling at a speed of 27 m/s and making a high-pitched song. The acceleration of this dive is the highest of any vertebrate, with a speed twice as fast as peregrine falcons relative to body length. At its maximum drop, 10 g of gravitational force are experienced.
• Male Anna’s and Selasphorus hummingbirds shake their outer tail feathers during courtship, creating an audible chirp due to aeroelastic flutter; this sound is mimicked in a wind tunnel by the feathers that are absent, which also allow the bird to sing at the same frequency but at a lower loudness.
• The sound is produced during courting dives when fast air flow past tail feathers causes flutter and vibration due to aerodynamics.
• Numerous species of their, such as the calliope, broad-tailed, rufous, Allen’s, streamertail, Costa’s, and black-chinned, make noises with their wings or tails while they fly, hover, or dive.
• Various their species produce different harmonics during their courtship dives.

Trill of wing feathers

• During normal flight, male rufous and broad-tailed hummingbirds (genus Selasphorus) produce a characteristic trill that sounds like a loud whistle or jingling sound.
• Air rushing through slots in the ninth and tenth primary wing feathers produces the trill, which may be heard up to 100 meters away.
• In terms of behavior, the trill notifies other birds of the male’s presence and sex, acts as an audible kind of aggressive defense, an incursion strategy, a means of communicating a threat, and improves mate attraction and wooing.

Flight

• Aerodynamic Studies:
• Wind tunnels and high-speed cameras have been used to study they flying in great detail.
• Lift generation during upstroke and downstroke was found in studies conducted on Rufous or Anna’s hummingbirds in wind tunnels.
• The birds’ “figure 8” wing motion produced a downstroke that supported 75% of the body weight and an upstroke that supported 25% of it.
• Wake Vortices and Hovering:
• While hovering, they form wake vortices beneath each wing.
• Previous beliefs on the generation of equal lift during wingbeat phases were questioned.
• Unlike insects of a similar size, such as the hawk moth, they don’t hover in them.
• Muscle Adaptations:
• Research on electromyography reveals distinct muscular adaptations in hovering rufous on them.
• The downstroke muscle, the pectoralis major, is not overly stressed.
• proportionally larger supracoracoideus (upstroke muscle) than in other bird species.
• An alula is superfluous when an organism is adapted for fast wingbeats during hovering and flying.
• Wingbeat Characteristics:
• The wings of a giant they beat as little as twelve times per second.
• They can beat their wings as fast as 80 times per second on average.
• In species suited to higher altitudes, larger wings mitigate the impact of low air density on lift production.
• Rain Response:
• Their adaptation to rain during flying is seen in slow-motion footage.
• They shake their heads and body like a dog does to get rid of water.
• They adjust their bodies and tails, quicken their wingbeats, and decrease their wing angle during periods of intense rain to offset the water weight that can account for up to 38% of their total body mass.

Natural Foes

Predators

Numerous observations have confirmed that praying mantises are recognized their predators. Apart from that, other predators that hunt hummingbirds include house cats, amphibians, dragonflies, orb-weaver spiders, and a variety of bird species, such as the roadrunner.

Parasites

Two genera of Ricinid lice, Trochiloecetes and Trochiliphagus, show a unique fondness for hummingbirds and often infest 5–15% of their populations. Hummingbirds are home to a highly specialized lice fauna. On the other hand, Myrsidea and Leremenopon, two genera of Menoponid lice, are noticeably rare on them.
