New Jersey Hummingbird Migration: 8 Awesome Travelers

Nine common questions regarding the migration of New Jersey hummingbirds are discussed in this article.

When Do New Jersey Hummingbirds Arrive?

The earliest arrivals of New Jersey hummingbirds are seen in April, and new arrivals continue through June.

New Jersey hummingbirds begin their spring migration north from as far away as Panama, or as close as Mexico. New Jersey hummingbirds arrive in New Jersey as early as April while some late migrators may arrive as late as June, but by the end of June, all hummingbirds that are migrating further than New Jersey are gone from New Jersey.

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.

Ruby-throated hummingbirds are by far the most commonly seen New Jersey hummingbirds, and will probably be the first migrating hummingbirds to be seen in New Jersey.

According to the Missouri Department Of Conservation, if New Jersey hummingbird enthusiasts start feeding them when they arrive, there is less chance they will move on and will decide to spend the summer in New Jersey.

New Jersey hummingbirds starting their spring migration north from Panama City, Panama, and flying across the Gulf of Mexico, need to fly 2,170 miles to reach Trento. If flying all over land they need to fly 4,381 miles.
New Jersey hummingbirds starting their journey north from Mexico, at the United States’ southernmost border at Brownsville Texas, must fly 1,639 miles to reach Trenton.

Are There New Jersey Hummingbirds That Live in the State Year-round?

There are no hummingbird species that live in New Jersey year-round, however, the Allen’s, Anna’s, and Rufous hummingbirds are seen and documented in the middle of winter.

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 New Jersey Hummingbirds Breed and Nest in the State?

The Ruby-throated hummingbird is the only hummingbird that breeds and nests in New Jersey.

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 for female hummingbirds to return to the area where they were born to build a nest, mate, and raise 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.

New Jersey 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 New Jersey Hummingbirds?

New Jersey hummingbird enthusiasts should put out hummingbird feeders in mid-April to attract the very earliest arriving migrating hummingbirds.
The majority of New Jersey migrating hummingbirds will arrive in June.

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 New Jersey hummingbirds will continue to arrive until about mid-June.
Hummingbirds seen in New Jersey after mid-June will be hummingbirds that will spend their entire summer in New Jersey.

Make sure to use high-quality nectar solutions in your hummingbird feeders; homemade nectar works best.

How Long Do New Jersey Hummingbirds Stay in the State?

New Jersey hummingbirds stay in the state for at least five months.
They will start arriving as early as April and most will be gone in October.
Some Allen’s, Anna’s, and Rufous are seen in New Jersey during winter, but most migrate south for the winter.
No hummingbird species live in New Jersey 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 New Jersey and those too old or injured to migrate will be the only likely hummingbirds New Jersey hummingbird enthusiasts will see during the winter.

The Rufous, Allen’s and Anna’s hummingbirds are the most probable migratory hummingbirds to decide to spend the winter in New Jersey.

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 New Jersey 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 New Jersey Hummingbirds Leave the State?

New Jersey hummingbirds begin leaving the state as early as late July and by late October they have migrated to their over-wintering areas in Mexico and Central America.
No hummingbirds live in New Jersey year-round.

Most of New Jersey 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 as early as late July, depending on their strength and energy, with the youngest hummingbirds finishing the fall migration by the end of October.

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 New Jersey 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 New Jersey Hummingbirds?

Mid-to-late October, or after a few weeks without any hummingbird sightings, is the ideal time to remove New Jersey hummingbird feeders for the winter.
Feeders are left up all winter by some New Jerseyans 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 (Amazon link), 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 (Amazon link).

The Allen’s, Anna’s and Rufous hummingbirds, who are New Jersey most likely uncommon winter visitors, depend on the nectar that some hummingbird fans leave out all winter long.

Most Black-chinned, Broad-tailed, Calliope, Mexican violetear, and Ruby-throated hummingbirds will not spend the winter in New Jersey 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.

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 a New Jersey Hummingbird to Migrate?

New Jersey hummingbirds require 55 hours of flying at its average migrating flight speed of 30mph to fly from Trenton to the most distant USA/Mexican border 1,639 miles away.
Hummingbirds migrating to Panama, 2,170 miles across the Gulf of Mexico, or 4,381 miles over land, will need to fly 72 or 146 hours respectively.

Some fly at a relaxed distance as slow as 1 hour per day, 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 near; by 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 New Jersey during this fall migration from July through 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.

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.
