When do ruby throated hummingbirds return

To extract the nectar, the bird inserts its long extensible tubular tongue deep into the honey wells of the flower, preferring tubed flowers, such as bee balm and columbines. When feeding from a larger flower with a very deep honey well, such as a tiger lily, it pierces the calyx, or neck of the blossom, with its bill and by this shortcut extracts the drop of nectar.

Bright-coloured flowers that contrast sharply with the background attract the hummingbird. It favours red flowers, followed by orange, both of which show up well in dark shady places, and visits green flowers only when the background foliage is another colour.

The hummingbird, like the bee, contributes to cross-pollination. As it visits one flower it is dusted with pollen, which it carries to another flower of the same species.

Holes made by the Yellow-bellied Sapsucker often release the sap of trees, which is also an important food source. The Ruby-throated Hummingbird is often seen gently buzzing a sapsucker in the expectation of being led to another food source.

Hummingbirds are easily attracted to feeders containing a solution of one part sugar to four parts water. This should be boiled to prevent fermentation, and the mixture should be changed at least once a week.

The hummingbird is a curious creature. Some birds take to a feeder at once; others learn to associate the strange contraption with sweet food only with difficulty. But once a hummingbird finds a feeder it will go back to it, as long as it is hanging in the same place. A hummingbird returning in spring always looks for the feeder where it last fed from it eight months before.

The hummingbird also drinks water. Flying across open water, it may descend like a swallow to the surface, touching it with the bill and leaving widening rings on the water to mark the site of the drink.

The male dives down towards the resting or feeding female. Like a pendulum he sweeps past her and up to a point 2 to 3 m in the air, then back along the same path in reverse. He repeats this swinging display time and again, all the while uttering squeaky notes. As he dives past the female his wings hum the loudest; as he swings closer to the female his hum becomes more intense and his speed increases. Abruptly, the display ends; both dart off together, to start again elsewhere.

After the pair has mated, the male takes no part in raising the young. He spends his time darting from flower to flower, sipping nectar, or sitting for hours atop a selected lookout watching for small insects. The female builds the nest without help. She usually saddles it on a limb of a leafy tree or shrub, 3 to 10 m above ground. A skilful builder, she uses cobweb and plant down, such as the fluff from catkins and cattails, as nesting materials.

Working with her bill, she cements these materials together and lashes the structure securely to the branch with sticky spider silk. She picks bits of lichen and sticks them on to the outside walls. This gives the nest the appearance of a natural knob.

With her body she moulds the inside of the cup and then draws loose ends over the edge and smoothes it all out with her bill.

The Ruby-throated Hummingbird lays two white eggs, the size of large peas. The female spends long sessions incubating, or warming, the eggs until they hatch, sheltered from rain and sun by the umbrella of green leaves under which she has placed her nest. She leaves to feed only briefly, and her trips from and to the nest are cautious, stealthy, and by selected routes.

The nestlings hatch after 11 to 14 days. No longer than honeybees, they are almost naked. Their eyes are closed at hatching and their bills are short. After five days their eyes begin to open and their feathers start to develop.

Later, the nestling can utter longdrawn peeps. The female broods, or keeps them warm, feeding them from her bill with food regurgitated, or brought up, from her throat. She picks up the droppings and carries them away.

Observers noted that one female had trimmed the nest branch with droppings placed in a neat row. The young birds leave the nest after 14 to 28 days, but may continue to be fed by their mother for several days. In the spring before migrating north, both adults and juveniles go through a complete moult, or shedding of old feathers, from which the young birds emerge in their full adult plumage. Generally speaking, populations of Ruby-throated Hummingbirds across Canada are healthy.

However, poor weather, including storms and untimely frost, sometimes pose serious threats. Finally, predation can threaten these birds. Because they may resemble large insects, hummingbirds are vulnerable to predators such as insect-eating hawks. Also, there is one record of a hummingbird flying over a pool being caught and swallowed by a fish.

What you can do Although hummingbird feeders draw this tiny bird to our backyards, feeders are often placed too close to windows. Since hummingbirds are highly aggressive and protect these food sources, they may mistake their reflection in windows for intruding birds and will attack and injure themselves.

Also, like most birds, they may consider windows to be openings through which they can fly. To protect hummingbirds, it is recommended that feeders be placed at least metres from windows.

Care must be taken in filling and maintaining hummingbird feeders, to ensure that they are a healthy source of food. Clean your feeders at least once a week to remove accumulations of mould or bacteria, which may be lethal to the birds.

As an alternative or complement to a feeder, why not plant a hummingbird garden? This tiny bird will enjoy the nectar from specific species of flowers as well as the insects in the garden.

The Northern Leopard Frog Lithobates pipiens is named for its leopard-like spots across its back and sides.

Historically, these frogs were harvested for food frog legs and are still used today for dissection practice in biology class. Northern Leopard Frogs are about the size of a plum, ranging from 7 to 12 centimetres. They have a variety of unique colour morphs, or genetic colour variations. They can be different shades of green and brown with rounded black spots across its back and legs and can even appear with no spots at all known as a burnsi morph.

They have white bellies and two light coloured dorsal back ridges. Another pale line travels underneath the nostril, eye and tympanum, ending at the shoulder. The tympanum is an external hearing structure just behind and below the eye that looks like a small disk. Black pupils and golden irises make up their eyes. They are often confused with Pickerel Frogs Lithobates palustris ; whose spots are more squared then rounded and have a yellowish underbelly.

Male frogs are typically smaller than the females. Their average life span is two to four years in the wild, but up to nine years in captivity. Tadpoles are dark brown with tan tails. Lampreys are an amazing group of ancient fish species which first appeared around million years ago. This means they evolved millions of years before the dinosaurs roamed the earth.

There are about 39 species of lamprey currently described plus some additional landlocked populations and varieties. In general, lamprey are one of three different life history types and are a combination of non-parasitic and parasitic species. Non-parasitic lamprey feed on organic material and detritus in the water column. Parasitic lamprey attach to other fish species to feed on their blood and tissues. Most, 22 of the 39 species, are non-parasitic and spend their entire lives in freshwater.

Males will usually migrate first followed by the females about 10 to 14 days later. The Fall migration south back to Mexico and Central America starts when the abundance of insects their main food source starts to dwindle with cold temps. This usually starts in late August into September. However, not all hummingbirds migrate each year. Some will spend the Winter along the western coast of North America.

If temps are generally getting warmer, flowers maybe blooming earlier resulting in flowers that are past bloom when hummingbirds arrive in the area Hummingbirds need the nectar from blooming flowers to fuel their long journey. They have the ability to alter their migration routes according to the flowers that are in bloom. Weather conditions will vary from year to year which affect when flowers will bloom in a particular area. Some years flowers will be in bloom when hummingbirds are passing through and another year they might not be blooming.

However, miles or so east or west of their usual migration route there may be flowers ready to fuel their needs. Studies have shown that hummingbirds have the sense to alter their routes according to the resources available. So this gives us hope that these very adaptable little creatures will have the capability to adapt and survive changing conditions. See our state by state hummingbird migration table listing the average arrival dates.

Submit your hummingbird sightings each Spring and Fall to update the latest travel patterns of hummingbirds to prepare for their arrival. Below is a table of the estimated Spring migration arrivals by state. We compiled this data taken from our visitors sightings from previous years. If it wasn't for you, our visitors, we wouldn't be able to relay all this important information to our fellow "Hummingbird Lovers"! We, and I'm sure you, appreciate everyone's participation in posting sightings every Spring during the hummingbird's flight to their Summer homes.

You will learn how this cross continental trip, truly an astonishing marvel of nature, is accomplished. We recommend hanging your feeders 2 weeks before the estimated time of arrival just in case they show up earlier.

If you have seen hummingbirds in your state earlier than these dates please let us know by contacting us.

This is also the time when nature lovers begin to put their feeders out. When to hang hummingbird feeders will vary according to the state you live in and the species you will see. For example, the Costa's hummingbird of Southern California and other southwestern states begin to arrive in late February.

On the other hand, the Ruby-throated hummingbird, the most predominate of the eastern states may not arrive in the northern states and Canada until May. It is true that most hummingbirds fly north in the spring and south in the winter to complete the hummingbird migration.

This hummingbird species may not leave the United States at all but migrate simply to lower elevations in the spring and higher elevations in the summer. It is a matter of food supply and climate. Another example of a deviation to the typical hummingbird migration Spring to Autumn schedule is the desert breeding Costa's hummingbird of Arizona that leave for a few short months but return in December to nest. You can keep track of their journey by using our interactive map and our list of sightings.

It can be fun to report to others your first sightings and keep a record for yourself from year to year. Enjoying one last Summer Party of on our back porch before her trip south for the Winter! It is a good idea to put up your feeders a few weeks ahead of the expected arrival. If you happen to be on a hummingbird migration route, a hungry traveler might enjoy the meal and possibly even stay.

Your regular hummingbirds will expect to return to their normal routine once they arrive. Are your feeders in good working order? Plant Flowers. Hummingbirds love nectar-producing flowers such as bee balm and honeysuckle. Be sure to plant early- and late-blooming flowers to give hummingbirds a selection all season long. Providing a combination of feeders and nectar-producing flowers is the best way to attract hummingbirds to your yard.

Provide Nesting Materials. Unlike some species of birds that prefer houses and nest boxes, hummingbirds build their own nests. They will not use birdhouses to lay their eggs and raise their young. Instead, provide them with nesting materials in your yard such as cotton, moss, feathers and spider silk so they can build nests on your property. Maintain Shelter. Hummingbirds are very active during the day, but they rest during the night hours.

Provide them with safe shelter such as trees and shrubs to protect them from wind, rain and predators.

Juveniles and non-breeding birds look similar to females. However, adult females have white outer corners on their tails while adult, non-breeding males do not.

In the summer, ruby-throated hummingbirds can be found throughout the eastern half of the United States and within parts of southern Canada. In the winter, ruby-throated hummingbirds travel to Mexico and Central America. Ruby-throated hummingbirds can be found in open woodlands, forest edges, meadows, grasslands, and in suburban parks, gardens, and backyards.

Ruby-throated hummingbirds are primarily nectar feeders, though they also will dine upon flying insects and caterpillars, particularly while nesting. Ruby-throated hummingbirds are naturally attracted to red and orange tubular-shaped flowers such as beebalm, cardinal flower, jewelweed, trumpet creeper, trumpet honeysuckle, and red buckeye. A list of plants that attract hummingbirds, butterflies and bees can be found on this page.

In addition, they will visit nectar feeders.
