Bird migration is a seasonal movement that allows us to look up at the sky and admire our favorite bird species as they seek another territory for shelter. However, as you may also notice, there will always be birds in your area, even with the bird migration happening. This article will focus on migratory vs resident birds and their behaviors.
Why? This is because birds are divided into migratory and resident birds. On one hand, migratory birds are the bird species that move from north to south to escape winter, while on the other, resident birds are the ones who choose to stay.
The question is, why is this so? Why would there be birds that would choose to remain in the cold, knowing that they could freeze to death, and why are there birds that choose to migrate even if the journey can be dangerous.
Those are the questions this article will answer. We’ll discuss here:

Bird migration is a regular seasonal movement where birds move from areas with low resources to areas with higher resources. The most common movement is from North to South, where northern populations of bird species (from Canada, Alaska, or Northern US) move further south for winter (Southern US, Mexico, Central America, South America).
Birds that perform this movement are what we call migratory birds.
As mentioned above, the movement is usually triggered by the availability of resources – food and nesting. At the same time, most of the birds need to move south to prevent the harsh winter weather.
There are three types of migration known to birds:
- Short-distance Migrants: These are birds that make very small movements to migrate. These birds don’t move because of the changes in the weather, but they do move because of food. Therefore, this type of migration usually just involves changing elevations, such as higher to lower elevations.
Short-distance migratory birds include waxwings, finches, and American Robins.
- Medium-distance Migrants: This type of migration covers birds moving a few hundred miles away from their breeding areas. Low food resources and shelter usually trigger the birds’ movement.
Medium-distance migratory birds include Eastern bluebird and Killdeer.
- Long-distance Migrants: These birds typically travel longer distances, usually from breeding ranges to wintering grounds. There are around 350 species of North American birds that travel long distances to migrate.
While short and medium-distance migratory birds move mainly because of food or shelter, long-distance migrants are different. They move because it’s what they evolved into, and it took a lot of practice of strength and endurance to cover such long flights.
The birds would also usually need to develop quick responses to weather, excellent navigation skills, and stamina.
Long-distance migratory birds include grosbeaks, Mourning Dove, and Ruby-throated hummingbirds.
Similarly, there’s another type of migratory bird that’s not very common, and they are what we call the Nomadic or Irregular migrants. These birds don’t have a regular schedule of movement, and it’s mainly just triggered by the availability of food resources.
Below, we list the most common migratory birds, their type of migration, and their breeding and winter ranges.

Why Do Birds Migrate?
As we continue to think about migratory vs resident birds, migration can be a difficult journey for birds. They meet a lot of hazards along the way, including storms, hunting, collisions, and even starvation when their stopover areas are out of food or shelter.
Out of many birds that migrate, some birds don’t survive. So, the question is, why would many birds choose to migrate, knowing the dangers that might come to them?
Well, it’s because these birds know that traveling miles away is less risky than staying in their breeding grounds for winter. On top of that, if no birds migrate, resources are depleted fast, and more birds won’t be able to survive.
Here are several reasons why birds migrate:
- Food: The number one trigger for birds to migrate is food. They move from areas where food is scarce to areas where food is abundant. This is a common reason for insect-eating birds as the supply of insects tends to be low once the temperature drops.
- Family: Birds also migrate in the hopes of finding a better breeding environment for their young. With better breeding conditions, the chance of survival of their species is higher, which will also increase or stabilize their population.
- Climate: Another obvious reason is that birds migrate because of the changing seasons. Some birds can’t handle too much cold and would choose to undergo a difficult journey if that means they can escape the harsh winter cold.
- Predators: Birds also change locations to avoid predators. Again, this is a tactic that can increase their chances of survival, especially their young.
- Disease: A large group of birds gathered in one place make them susceptible to parasites and diseases. If one bird catches a disease and there’s a large flock surrounding it, it’s only a matter of time until that disease spreads. But when birds disperse to different locations, the infection wouldn’t spread just as fast.
Depending on their reason, birds migrate to increase their chance of survival.
Below, we want to share with you some unbelievable journeys some birds have taken…
Unbelievable Bird Journeys
- Arctic Tern: These birds have taken the longest journey any bird has ever taken. They have traveled 71,000 km a year, flying from Greenland to Antarctica or from one side of the world to the other.
- Great Snipe: These birds are the fastest among all migrating birds. The bird flies as far as 6,800 km and at speeds of 95 kph.
- Bar-headed Geese: These birds fly the highest among all the other birds in the world. They can reach altitudes of over 8,500 meters.
- Bar-tailed Godwit: Nothing can beat these birds if we’re talking about endurance. These species can fly for over 11,000 km without any rest. The flight is estimated to be around eight days!
- Red Knot: Another impressive migration is done by the Red Knots. They fly around 15,000 km every year from the southern coasts of Chile and Argentina to the Canadian Arctic Archipelago.
Why Do Some Birds Choose To Not Migrate?
Now, if some birds can take a risk to travel long distances to increase their chances of survival, why would some birds choose to stay? Well, that’s because their chances of survival are higher if they stay.
Here are some reasons why people choose not to migrate:
- Save Energy: Birds choose to stay to preserve their energy. They would rather use their energy to forage, protect themselves from predators, and keep themselves warm to survive the winter instead of traveling miles away to avoid it.
- Defend their territory: For these birds, maintaining their territories is very important.
When they migrate to wintering ranges, it would mean that they would have to find a new area to nest or find shelter. But if they stay in their breeding ranges, they get to protect their breeding territory from any other birds that try to take it from them.
- Nurture their young: Some birds choose to stay to ensure that their young are well-taken care of. As some young birds are not yet ready to travel far, their parents choose to continue to care for them, even if that means they have to submit themselves to harsh weather conditions.
How Do Resident Birds Survive?
However, if birds choose to stay under harsh weather conditions, how do they survive?
Well, first of all, birds are warm-blooded animals. This means that their normal body temperature is significantly higher than ours, which allows them to stay warm even if temperatures are already low. On top of this, their feathers are great insulators and keep them warm when temperatures go cold.
Aside from physical adaptations, birds also have behavioral adaptations that increase their chances of survival.
- Fluffing: Birds fluff out their feathers which creates extra air pockets that provide additional insulation for them. This gives the birds a fat and puffy appearance that we may find cute, but the truth is, it keeps them warm.
- Tucking: This adaptation is mainly designed to help prevent the birds’ legs from getting frostbite. Some bird species hide one or both of their legs to shield them from extreme cold. Some even tuck their bills into their shoulders to breathe warm air into their bodies.
- Shivering: This action helps raise the bird’s temperature quickly. It’s a form of adaptation that uses up many of the birds’ calories, making it only a short-term solution for them. Therefore, it is only used when the temperature is freezing.
- Roosting: While most bird species are territorial during the breeding seasons, many choose to flock with other birds, especially if that means surviving. By roosting, birds are able to share their body heat with other birds, increasing the body temperature of each and therefore increasing their chances of survival.
- Torpor: Torpor is like hibernation for birds. It’s when they sleep for longer periods to preserve their energy during the cold winter nights. Birds undergoing torpor tend to lower their temperature to 50 degrees, which can be very dangerous for them as this can make them more vulnerable to predators.
At the same time, birds doing torpor must immediately have access to food as soon as they wake up to replenish their energy.
FAQs on the Difference Between Migratory and Resident Birds
What’s the advantage of migration in birds?
Bird migration increases the bird’s chances of survival. It helps them avoid the cold winter weather, allows them to go to an area with more food, or increases their chances of avoiding any big predators.
In other words, birds migrate mainly for survival.
What are the disadvantages of bird migration in birds?
Bird migration is not an easy journey. If anything else, it can be perilous, and birds can meet a lot of difficulties such as:
What can I do to help migrating or non-migrating birds?
Migrating or not, birds need the same things – food, water, and shelter. No matter where you are, and no matter what the season is, it’s important that you fill your bird feeders and make them available for birds.
This way, migrating birds would be able to see them and have something to eat while they rest, or non-migrating birds will always have somewhere to go when they’re looking to replenish their energy,
Final Thoughts on the Difference Between Migratory and Resident Birds
Whether birds choose to travel or not, they all have one goal: survival.
Migratory birds move to areas where resources are abundant to increase their chances of survival, while resident birds stay within their breeding range for survival, too. This technique is also ingenious for birds, as it helps distribute food resources equally to all of them.
Gathering in one place just means faster depletion of resources. But moving from areas with lower resources to areas with abundant resources allows them to consume food in their wintering grounds while their breeding grounds recover and grow more food.
This whole migration is a survival technique, and it’s really effective for birds.
