When Do Maine Hummingbirds Arrive?
The earliest arrivals of Maine hummingbirds are seen in late April, and new arrivals continue through June.
The majority of Maine hummingbirds arrive in May.
Maine hummingbirds begin their spring migration north from as far away as Panama or as close as Mexico. Maine hummingbirds arrive in Maine as early as April, while some late migrators may arrive as late as May.
By the end of June, all hummingbirds that are migrating further than Maine will be gone from Maine.
The first migrating hummingbirds will be males, followed by females about a week later. The males arrive first to stake out the territory that they will defend as they try to attract a female.
Ruby-throated hummingbirds are by far the most commonly seen Maine hummingbirds, and will probably be the first migrating hummingbirds to be seen in Maine.
Watch for the male’s vividly colored gorget; a week or so later, the females will begin to appear at your feeders.

According to the Missouri Department Of Conservation, if Maine hummingbird enthusiasts start feeding them when they arrive, there is less chance they will move on and will decide to spend the summer in Maine.
The first migrating hummingbirds will be males followed by the females about a week later. The males arrive first to stake out the territory that they will defend as they try to attract a female.
Maine hummingbirds starting their spring migration north from Panama City, Panama need to fly about 4,870 miles to reach Bangor Maine over land or 2,549 miles flying across the Gulf of Mexico.
Maine hummingbirds starting their journey north from Mexico, at the United States’ southernmost border at Brownsville Texas, need to fly 2,062 miles to reach Bangor Maine.
Are There Maine Hummingbirds That Live in the State Year-round?
There are no hummingbird species that live in Maine year-round, however, the Ruby-throated and Rufous hummingbirds have, on very rare occasions, been seen in the middle of winter in Maine.

The general public is unaware of how cold-tolerant hummingbirds actually are.
Some banded hummingbirds have been observed at temperatures as low as -9 degrees Fahrenheit with a wind chill of -36 degrees Fahrenheit, according to eBird.org.
Which Maine Hummingbirds Breed and Nest in the State?
The Ruby-throated hummingbird is the only hummingbird that breeds and nests in Maine.
Ruby-throated – The Ruby-throated hummingbird has an extensive breeding area that covers the entire eastern half of the United States and extends into Canada as far west as Alberta.

The entire reason for northern migration, much like salmon swimming upstream to their place of birth to lay eggs, is to return to the area where they were born. There the female builds a nest, mates, and raises a family.
When a female hummingbird arrives at the breeding grounds, her attention shifts to building a nest and then looking for a mate.
Hummingbird females prefer to build their nests in deciduous trees, 10 to 20 feet above the ground.
It will take her between 5 and 7 days to construct the nest of materials such as plant down, moss, and fine plant fibers, decorated with lichens and held together by spider webs.

Each species of male hummingbird has its own unique mating dance ritual of courtship to attract a female. They do perfectly choreographed dives and dance maneuvers to attract a flirty female.
See my article: Hummingbird Dance: 5 Interpretive Explanations
During the mating ritual, there is no penetration since male hummingbirds lack external sexual organs.
The “Cloacal Kiss occurs when the cloacae, (pronounced “kloh-ay-see”), of both hummingbirds are brought together during the brief mating procedure, which lasts only three to five seconds.
After the Cloacal kiss, the female must begin building the nest immediately.
Each brood of hummingbirds typically produces two eggs, laid on consecutive days.
The majority of hummingbirds have two broods annually, although some may have more depending on the timing of their migration and the duration of the days they spend in their breeding areas.
Maine nesting hummingbirds usually have 2 broods per year but some may have time to work in a third brood.
When Should I Put Up My Feeders For Maine Hummingbirds?
Maine hummingbird enthusiasts should put out hummingbird feeders at the beginning of April to attract the very earliest arriving migrating hummingbirds.
The majority of Maine migrating hummingbirds will arrive in May.
If migrating hummingbirds are fed when they start to arrive there is less chance of them moving on.
Hummingbird aficionados can reduce the likelihood that hummingbirds will leave the state and elect to spend the summer thereby providing food for them as soon as they arrive, according to the Missouri Department of Conservation.
Approximately one week after the arrival of the male hummingbirds, the females will follow.
Other Maine hummingbirds will continue to arrive until about mid-June.
Hummingbirds seen in Maine after mid-June will be hummingbirds that will spend their entire summer in Maine.
Make sure to use high-quality nectar solutions in your hummingbird feeders; homemade nectar works best.

How Long Do Maine Hummingbirds Stay in the State?
Maine hummingbirds stay in the state for at least six months.
They will start arriving as early as April and most will be gone in October.
Some Ruby-throated and Rufous, have been seen in Maine during winter, but most migrate south for the winter.
No hummingbird species live in Maine year-round.
The general public is unaware of how tolerant hummingbirds actually are.
Some banded hummingbirds have been observed at temperatures as low as -9 degrees Fahrenheit with a wind chill of -36 degrees Fahrenheit, according to eBird.org.
Some migrating seasonal hummingbirds choose to over-winter in Maine and those too old or injured to migrate will be the only likely hummingbirds Maine hummingbird enthusiasts will see during the winter.
The extremely cold-tolerant Rufous hummingbird is the most probable migratory hummingbird to decide to spend the winter in Maine, but they are rarely seen even during the summer months.
In Pennsylvania, a state known for its cold harsh winters, the Valley Forge Audubon Society reports winter sightings of the Allen’s, Calliope, Rufous, and Black-chinned hummingbirds.
Because hummingbirds have such long memories, they will revisit the flowers and feeders they frequented during their spring migration and will remember them when they migrate back to the south in the fall.
See my article: Hummingbird Adaptation and Remarkable Ability to Locate Food
The most common Maine hummingbird seen during the hot summer months will be the Ruby-throated hummingbird with the Rufous hummingbird being a very distant second.
Finding strategies to provide your hummingbirds with cool nectar might be crucial when the summer heat becomes unpleasant and tough to handle.

When Do Maine Hummingbirds Leave the State?
Some Maine hummingbirds begin leaving the state as early as August, and by late October they have migrated to their over-wintering areas in Mexico and Central America.
No hummingbirds live in Maine year-round.
Most of Maine’s migrating hummingbirds are gone by the end of October but a few stragglers might stay until the end of the year.
A few older hummingbirds will be the first to start the fall migration, maybe as early as late August, depending on their strength and energy, with the youngest hummingbirds finishing the fall migration by mid-November.
An article from the University of Southern Mississippi states that the hummingbirds that are the oldest will begin their migration earlier than the others.
This elongated migration time frame ensures late straggling migrants have enough food available to fuel their bodies before making the long taxing migration south for the winter.
Some migrating hummingbirds Maine will possibly see during the winter are migrating hummingbirds that are too old or injured to migrate.
The circannual (annual internal clock) and circadian (day internal clock) rhythms cause hummingbird migration.
The inclination of a single hummingbird to migrate is triggered by a variety of circumstances, including variations in temperature, time of year, and weather; other causes include a loss in food supplies and a reduction in sunshine due to shortened days.
Similar to the spring migration, male hummingbirds start the fall migration to the south first. As soon as the female hummingbirds have finished rearing their young to the point that they can travel independently, they will set out on their southern fall migration.
When Should I Take Down My Feeders For Maine Hummingbirds?
Mid-to-late October, or after a few weeks without any hummingbird sightings, is the ideal time to remove Maine hummingbird feeders for the winter.
Feeders are left up all winter by some Maine to feed the uncommon winter hummingbirds and those that are too old or injured to migrate.
The dilemma hummingbird enthusiasts struggle with every year is whether to leave the hummingbird feeders up all year or take them down during the winter.
The challenge then becomes preventing the nectar from hummingbirds from freezing.
See my article: 11 DIY Ways To Keep Hummingbird Nectar From Freezing
Investing in a hummingbird feeder warmer, like the Hummer Health feeder heater, is one approach to prevent hummingbird nectar from freezing.
Unfortunately, it is only compatible with a select few types of hummingbird feeders, like the Aspect’s HummZinger feeder.
The Ruby-throated and Rufous hummingbirds, who are Maine’s most likely uncommon winter visitors, depend on the nectar that some hummingbird fans leave out all winter long.
Most Ruby-throated, Rufous, Calliope, and Mexican Violetear hummingbirds will not spend the winter in Maine and will decide to migrate south to Mexico for the winter.
Keeping hummingbird feeders up during the winter is a noble gesture that helps other migrating species that are injured or too old to migrate by providing them with nectar.

See my article: Should I Keep My Hummingbird Feeder Out During the Winter?
Hummingbird enthusiasts who leave hummingbird feeders up all winter provide much-welcome nutrition for late migrators and hummingbirds too old or injured to migrate.
The general public is unaware of how tolerant hummingbirds actually are.
Some banded hummingbirds have been observed at temperatures as low as -9 degrees Fahrenheit with a wind chill of -36 degrees Fahrenheit, according to eBird.org.

Hummingbirds that depend on these wintertime feeders may die if hummingbird feeders are taken down in the middle of winter during periods of below-freezing temperatures.

How Long Does It Take Maine Hummingbirds to Migrate?
It takes Maine hummingbirds 68 hours of flying at their average migrating flight speed of 30mph to fly from Bangor to the most distant Mexican border 2,062 miles away.
Hummingbirds migrating to Panama 2,549 miles across the Gulf of Mexico or 4,870 miles over land, will need to fly 84 hours or 162 hours respectively.
Some fly at a relaxed distance as slow as 1 hour per day, and others fly up to 500 miles non-stop in about 20 hours as some do while migrating across the Gulf of Mexico.
Unlike other migrating birds, hummingbirds do not travel in flocks.
Individual hummingbirds travel according to their own internal clock.
This staggered migration pattern ensures resources are not consumed and depleted all at once.
Hummingbirds regularly acquire between 25% and 50% of their body weight as migration draws nearby eating more nectar from feeders and blooming plants and by collecting more insects in midair for protein.
This rise in body fat provides the hummingbird with energy for its protracted migration flight.
Expect to see an increased volume of southern migrating hummingbird visitors to your feeders in Maine during this fall migration in September and October.
Hummingbirds that stopped by your feeders in the spring will remember exactly where it is, and they will probably stop by again en route to their overwintering grounds in Mexico and Central America.

Where Do Maine Hummingbirds Go in the Winter?
Maine hummingbirds, the Ruby-throated, Rufous, Calliope, and Mexican Violetear, travel south to over-winter in Mexico, Guatemala, Belize, Honduras, El Salvador, Nicaragua, Costa Rica, and Panama.
Ruby-throated – The Ruby-throated hummingbird overwinters primarily in Mexico, Guatemala, Honduras, El Salvador, Nicaragua, Costa Rica, and Panama. Ruby-throated hummingbirds are seen in some years, during the winter months, in scattered areas throughout the USA including New Mexico, Texas, Florida, Georgia, South Carolina, and North Carolina.

Mexican Violetear – The Mexican Violetear hummingbird overwinters primarily in Mexico, Guatemala, and Honduras. Mexican Violetear hummingbirds are seen in some years, during winter months, in scattered areas throughout the USA including Arizona, Texas, and Louisiana.
Every hummingbird has an exceptional memory. Throughout their spring migration, they can recall every flower or feeder they visited, and they will revisit those spots every year.
Hummingbirds have been seen to return to a feeder even after it has been removed for a few years.
