Ruby-throated Hummingbirds do not hibernate, but others do

They are less active in winter but they don't migrate. It was just looking for a place to rest for a minute that offered a little shelter from the weather.

Many survive the same way reptiles and amphibians do. They hibernate by digging into the mud and burying themselves within. Others are capable of surviving in low-temperature water. The rest migrate like birds.

How fast the wings beat depends on species, its weight, and what it is doing.\n\nTake the simple case:  a Ruby-throated Hummingbird, hovering in open space, has a wingbeat rate of about 50-52 times per second, which sounds like a low hum and is responsible for the American name, "humming bird."  Another onomatopoeic name, in which the word sounds like its meaning, is the Cuban name for hummingbird, "zum-zum."  \n\nThink about that:  50 times per second is equal to 3,000 times per minute!\n\ncheck this url out for more info:\nhttp://www.hummingbirdsociety.org/eletters/Hummingbirds.On-Line.Issue.5.htm

Yes, Birds can cover MANY miles each and every day. When they stop to feed, drink or bathe they pad around in water. Most often nothing sticks to the birds, but there are the times that eggs and materials stick on their feet and legs. This most often happens with ducks and their webbed feet.

Bears are thought to hibernate or sleep for 5 months to 7 months each year. In very cold climates bears may hibernate longer than in moderate climates, because the food supply in frozen climates is under snow cover longer. \n\nBears in captivity DO NOT hibernate at all because there is a ready food supply. Most bears do not eat, defecate or urinate during hibernation. This is accomplished through their metabolic systems. The bears appear to maintain the water content of their blood. The breakdown of fat reserves balance water losses. A small amount of urea is formed and is degraded and recycled into non-toxic elements. Much is yet to be known about this metabolic cycle. Grizzlies hibernate in dens. Some grizzlies utilize natural caves for dens, while others build dens in the sides of mountains, under hollow trees or other forested locations.

the answer is probably that if it is less than 40 degrees F, crickets die/hibernate and dont chirp at all. above 40, the formula would work, giving a positive number of chirps.

In my experience, hummingbirds won't visit a feeder that is close to another one frequently visited by larger birds (i.e. Blue Jays, Cardinals, Cowbirds, etc.).  They are very easily frightened.  I would put the hummingbird feeder in a nice, quiet spot, at least ten feet away from other feeders, preferably in a tree or other sheltered area.  Also, make sure you change the food every 1-2 weeks, as it does go bad.  Good luck!

The Life Cycle of the Bumble Bee.\nEvery Autumn as the first frosts begin the mated young queens seek out a place to hibernate in safety. If you come across a live but sleepy bee in a pile of leaves in Winter don't damage it. Its not dying, just in a deep cold sleep like a hedgehog. Put it back where you found it and cover it gently against the cold.\n\nIn the first warm days of Spring you may see the large queens flying busily about the early bulbs and flowers. These large slow bees are searching for nectar and pollen to turn into honey and food for their newly hatching brood. So the organic gardener plants lots of pollen producing flowers and leaves an unmown patch of early dandelions in the wild garden or hedgerow to feed the young queens.\n\nThe queen will locate a suitable place to build her nest. There are over 200 types of bumble bee and they look for a variety of sites. Most common are the leaf litter in a hedge bottom, an old mouse hole, a cool dark place under a large stone or under the wooden floor of a garden shed or other building. Because the bumble bee does not live in a large colony the nest is usually little bigger than half a grapefruit even in the busiest days of high Summer.\n\nThe queen begins a new nest with a ball of pollen and wax into which she lays just a few (approx 6 ) eggs at a time. When the eggs hatch they try to eat their way through the pollen reserve but the queen continually adds to the pollen and wax sealing them in. Eventually the grubs pupate and the queen spins a bright yellow cocoon of the finest silk from which the grubs emerge a few days later as fully grown worker bees.\n\nAs soon as they dry their wings the worker bees begin work to support the colony and their queen. She continues to lay eggs but as it takes more and more of her time the pollen and nectar collection is delegated to the workers, the queen spending her whole time in the nest. \n\nThis co-operation continues throughout the high days of late Spring and Summer until the nest has reached the right size for its species. At that point the queen lays eggs destined to become next years queen bees as well as drones or male bees. The drones once hatched leave the nest and live independent lives, their only purpose being to mate with the young queens to ensure the survival of the species. Unlike honey bees the young bumble queens will continue to live and work in the mother colony for the remainder of the Summer and Autumn.\n\nCome the first sharp drop in temperature and frosts the old queen, her workers and the independent drones will die. Only the newly mated queens will survive in hibernation to begin the cycle again the following Spring.

It's called 'humming'.

yeah..though i think they just hibernate...don't they. I'm being swarmed by ladybugs,it's crazy! Don't worry though global warming isn't happening!

some of them might hibernate. hibernation allows some small mammals to reduce their metabolism during times of scarce resources, such as winter. they accumulate body fat for a while, then it's like their system «shuts down»: their body temperature decreases, their pulse too, and they might breathe as few as 1 to 10 times a minute!\nhibernation is a real advantage because, when it's cold, it would take a lot more energy to keep normal body heat, consuming more nutrients, when, in fact, it's the time of year when it's more difficult to feed!

The largest hummingbird is called Patagona gigas, it lives here in Argentina and it's as large as a small songbird (about 10 cm I guess). They're also very dull-colored, in contrast with other, smaller species.\nMost species are smaller, I'd say 3-6 cm without the tail. \nHummingbirds are native to the Americas only, and there are none in Portugal. \n\nHowever, hummingbirds once lived in the Old World, since fossils have been found there:\nhttp://news.bbc.co.uk/1/hi/sci/tech/3691169.stm

It doesn't adapt to it's environment, it only lives and survives in conditions that it is suited to. In the winter it hibernates and it the summer it flies around and feeds.

The first point you need to realise is that bears don't really hibernate. They simply go to sleep for the winter, which is quite a different thing.\n\nIt is perfectly normal for a 'hibernating' bear to wake up and go for a walk around outside for a few hours or a few days and then go back to sleep. So that answers your question regarding bears. It will do them absolutely no harm whatsoever for them to be woken up.\n\nReal hibernating animals however are small mammals. The biggest of the true hibernators is the marmot, which is about 100X smaller than a bear. These true hibernators do not simply go to sleep, they enter a state of virtual suspended animation. All their body systems slow down. Many    systems such as the kidneys shut down entirely. Body temperature falls to just a few degrees above freezing.\n\nIt is quite impossible to wake these hibernating animals through normal means. They have a pre-programmed time clock that will wake them up, and nothing short of drugs will alter that.\n\nHowever if they are woken through the use of drugs and returned to the wild they will die. Once the annual hibernation cycle is disrupted it can't be restarted until the following autumn. Being awake in the middle of winter they will either freeze or starve to death within a day.\n\n\nIn summary: hibernation can never be disrupted without killing the hibernator. Bears however don't truly hibernate, they simply sleep, and it won't harm a bear to be disturbed during their winter sleep.\n\nHowever they will be mighty angry and probably take your head off. And having done that they will almost certainly eat you before going back to sleep.

When perching birds sit, a tendon on the backside of the ankle automatically flexes locking their toes around the branch. With feet locked, sleeping birds don't fall. As the bird stands up its feet release.

Frogs hibernate in burrows or under leaves or bury themselves in mud. Their organs contain a high concentration of glucose which prevents the frogs from freezing.
