¿Did you know that migratory birds can fly up to 4,000 kilometers on a single journey?
Every spring and autumn, we witness the spectacle of millions of birds embarking on a long and risky journey from their breeding grounds to their wintering areas and back.
This annual migration mainly happens at night, when the winds are gentler, and the moon and stars serve as guides.
Birds tend to follow established migration routes. Usually from north to south and with places to rest and recharge along the way. Many bird species share routes and must face harsh weather conditions, dehydration, hunger, and predators to get where they want to be.
In Colombia, the country of birds, we welcome these migratory birds.
Get to know the migratory birds that come to our country:
Water birds depart and arrive at lakes, lagoons, and wetlands, where they find fish, crabs, aquatic insects, and other animals for food, as well as plants that grow along the edges.
Land birds, like us, live in forests or open areas such as pastures and crops, depending on our preferences. Some of us even reach towns and cities. In all these places, we find food like fruit, insects, and flower nectar.
Shorebirds are a mix of land and water birds, as they live along the edges of lakes, lagoons, or the coast. There, they find food like crabs, worms, insects, and snails.
Las aves migratorias no tenemos un reloj en nuestras manos (¡perdón, en nuestras patas!), pero existen señales que nos indican que debemos partir en busca de condiciones apropiadas para vivir durante los meses del invierno de los extremos del continente. Por ejemplo, los insectos empiezan a desaparecer y nos vamos quedando sin alimento, y las temperaturas empiezan a bajar. For the return, we don't have such clear signs, but there’s an inner clock within us that tells us it's time to go! We feel an overwhelming urge to find a mate and raise a family, and we know it's better to do that in a place with less competition from other birds, like in the tropics. So then we just take flight.
Some birds fly incredibly long distances, like the Arctic Tern, which almost flies around the entire globe, covering 40,000 kilometers and making it the bird with the longest migration route in the world.
We birds can travel for weeks or even months! For example, a peregrine falcon takes the air from September to November to travel from Canada to Argentina! But some birds make migrations that last only a few days within the same country they are from.
Actions that contribute to the safe passage for our travellers:
Conserve and restore important natural areas for birds.
Minimize the use of pesticides and light pollution at night.
Promote awareness about the importance of migratory birds.
Advocate for laws that protect their habitats and migration routes.
Work with global organizations for their conservation.
Use window stickers and other methods to prevent birds from colliding with glass structures.
Help with the monitoring and study of migratory birds.
Black-and-white Warbler (Mniotilta varia)
Hello, I’m Tilda, the Black-and-white Warbler. I am the bird with the most eye-catching stripes of the whole forest. You’ll see me hopping among branches searching for tasty insects. I love being in large trees. Some might confuse me with the male plumage of the Setophaga striata, but don’t be fooled! My black-and-white striped pattern and playful behavior make me unique. So, if you see someone moving from branch to branch with style, it’s probably me.

Blue-winged Teal (Spatula discors) I’m Spatu, the duck with blue patches on my wings! Males like me, have a white moon-like spot in front of their eyes. We can't forget the black bill that gives us a sophisticated look! Females, on the other hand, are plainer: they are darkish brown with a pale spot next to their beaks. I like freshwater lagoons, lakes, and swamps, but during winter, I love to visit brackish waters (Mix between fresh and seawater). I eat a little bit of everything: plants, insects, and those delicious aquatic crabs.

Many of us migratory birds have an incredible spatial memory that allows us to remember our migratory routes and important landmarks along the way. This ability is crucial to our survival and success during our migrations.
Upon returning to our breeding or wintering areas, we can remember precise routes and specific locations where we found food or shelter in the past. This spatial memory helps us navigate efficiently and locate the best places to feed and rest, even after being away for months.
Reinita de Canadá (Cardellina canadensis)
¡Hola, soy Lina la Cardellina! Me encanta destacar con mi plumaje, que es de un elegante gris azulado arriba y un vibrante amarillo abajo. No puedo olvidar mis llamativos anteojos amarillos y mi collar de rayas negras que le da un toque especial a mi look. Mis piernas son de un bonito anaranjado pálido.
Las hembras como yo tenemos un collar más sutil comparado con el de los machos. Me encuentro felizmente en vegetación baja, especialmente en esos bosques húmedos y matorrales que tanto me gustan. ¡Ah, y me encanta anidar en el suelo, donde me siento más segura! Mi dieta está llena de insectos. Y no solo eso, ¡soy una de las aves migratorias que recorre mayores distancias! Durante el invierno, voy a disfrutar de la calidez de Suramérica.

Reinita cerúlea (Setophaga cerulea)
Hola, soy la Reinita cerúlea, una especie migratoria con una vida llena de aventuras, usualmente crío en América del Norte, y cuando llega el invierno, me dirijo hacia el sur para disfrutar del calor de América del Sur. Mido entre 11 y 12 cm, perfecta para mis travesías.
Los adultos como yo mostramos un claro dimorfismo sexual y cambios con la edad, pero no cambiamos nuestro plumaje con las estaciones. Durante mis migraciones, vuelo a través del Golfo de México, el Caribe y América Central, hasta llegar a mis destinos de invierno en los bosques de montaña del noroeste de América del Sur, especialmente en la majestuosa Cordillera de los Andes.

Cerceta aliazul (Spatula discors) ¡Soy Spatu, el patito pequeño con parches azul en la parte superior de mi ala! Los machos como yo lucimos una media luna blanca justo delante del ojo. Las hembras, por otro lado, son más discretas: están estampadas en marrón oscuro y tienen un toque de la media luna blanca que llevamos nosotros en la cara. ¡Y no se me olvida el pico negro que me da ese aire sofisticado! Vivo en lagunas, lagos y pantanos de agua dulce, aunque durante el invierno, me encanta darme una vuelta por aguas salobres, es decir que es menos salada que el agua de mar. Me alimento de todo un poco: vegetación, insectos y esos deliciosos crustáceos acuáticos.

About two weeks before our migration, we started eating
much more than usual in order to obtain large reserves of
fat that gives us energy. Along the way, we sometimes stop at
some places for several days to gain a little weight and replenish our strength, or we make short stops to rest and
eat a little, and then keep going until the end!
During our migration, some of us used air currents to save energy. We take advantage of favorable winds and rising thermal currents to rise more easily and travel long distances with less effort.
Thermal currents are columns of warm air that rise from the earth when the sun heats the surface. By landing on these updrafts, we can rise without having to constantly flap our wings, which reduces energy expenditure. In addition, favorable winds help us maintain a constant speed and cover long distances more quickly.
This strategy of flying on air currents allows us to maximize our efficiency during long migratory journeys, conserving our energy and optimizing our resources to meet the challenges of migration.

Fork-tailed Kite (Elanoides forficatus) I’m Elanor the graceful raptor. With my unique shape, long and narrow wings that let me fly with elegance and a very forked tail that moves with style. My plumage is a contracting combo of white and black, with a touch of bright gray-blue on top. You’ll often see me soaring and gliding through the air. I prefer wooded habitats, especially those near rivers and ponds, which is a perfect environment for my prey. My diet is full of action, as I mainly feed on insects I catch mid-flight with agility.

Throughout our migrations, we can communicate with each other through specific calls. These vocalizations help us coordinate our movements, maintain group cohesion during flight, and warn of possible dangers.
Our vocalizations during migration are a multifunctional tool that helps us coordinate our movements, maintain cohesion, warn of danger, and strengthen our social interactions. This communication is essential for the success and security of our immigration journeys.

During our migration, some of us experience a crucial process called molting, which involves replacing our old feathers with new ones. This process is essential for our well-being and efficiency during our long trips. We will explore how and why molting occurs at different stages of migration.
Loro Orejiamarillo (Ognorhynchus icterotis)
¡Hola, soy Gonza el Loro Orejiamarillo!
Soy una especie endémica de los Andes colombianos, vivo a alturas de entre 1.200 y 3.500 metros sobre el nivel del mar, pero, ¡atención! Estoy en peligro de extinción. Me encanta esconderme en los bosques andinos húmedos, especialmente donde crece la Palma de Cera. ¡Esta palma es mi casa y mi lugar de descanso.

During our migration, we experience a significant increase in our metabolism. This allows us to accumulate large fat reserves before the trip, which we use as a source of energy during the flight. This process, known as "hyperphagia", means that we overeat to store the necessary fat.
Raptors or birds of prey can fly over mountains, taking advantage of air currents created by the hot sun during the day. Or fly over rivers and lakes, travelling across the continent.
Prothonotary Warbler (Protonotaria citrea)
Hi! I’m Citri, a charming warbler who lives in humid forests. Males stand out with their vibrant yellow heads and belly, greenish back, and elegant bluish-gray wings. Females and young ones have a slightly more paler look, but they still have their appeal. My song is a very distinctive set of 6 to 10 high-pitched notes, with a sound that can be described as “tsweet.” Here’s an interesting fact: I’m one of the only two warblers that nests in holes! So, I’m always ready to impress anybody with both my melodious song and nesting skills.

Some species of migratory birds, such as nightingales and songbirds, migrate primarily at night. This nocturnal behavior allows us to avoid predators that are active during the day and also reduces the risk of dehydration and overheating. Flying under the cover of night helps conserve our energy and maintain a more stable body temperature, which is crucial for long non-stop journeys. In addition, the lower activity of other animals and the quietness at night offer us a safer and less stressful environment during the trip.

Raptors or birds of prey can fly over mountains, taking advantage of air currents created by the hot sun during the day. Or fly over rivers and lakes, travelling across the continent.
Shorebirds usually fly at night to avoid predators and to eat during the day. Their route follows inland or coastal water, or islands and sometimes they fly over the Atlantic Ocean!
Water birds also fly between continents, seeking out lakes and rivers. And songbirds, like us, fly between continents, looking for forests where we can find food.
Migratory birds orient ourselves in various ways on our trips.
During migration, our navigation skills are amazing. For example, when we fly at night, we look at the stars to stay on track. The constellations act as celestial maps that help us maintain the correct direction. During the day, the sun is our main reference; We know how to adjust our flight based on its position in the sky.
Those of us who generally travel at night, like warblers, guide ourselves by seeing the position of the stars, as sailors do.
Cerulean Warbler (Setophaga cerulea)
Hello, I’m Seth the Cerulean Warbler, a migratory species with a life full of adventures. I usually live in North America, but when winter comes, I head down south to enjoy the warmth of South America. Adult males like me are bright blue. On the contrary, the adult females and young birds are light bluish-green. During migrations, I fly through the Gulf of Mexico, the Caribbean, and Central America, all the way to my winter destinations in the mountain forests of northwest South America, especially in the majestic Andes.

In our migration, some of us fly non-stop to cross spaces as large as the Gulf of Mexico, which is a thousand kilometers long.
This type of continuous crossing is an impressive challenge, since we need to stay in flight for many hours without rest. Our ability to make uninterrupted flights of this magnitude demonstrates the incredible resilience and adaptation we have developed to face the long distances of our migrations.
Gavilán aludo (Buteo platypterus)
¡Hola, soy Don Buteo, el gavilán aludo! Con mi pico corto pero afilado y mi plumaje en blanco con negro (a veces con toques de amarillo), me destaco en el reino de las aves.

By combining the information we get from the sun with the signals we perceive from the Earth's magnetic field and other visual reference points, we achieve precise and effective orientation.
We also remember mountains, lakes, rivers, deserts and even cities! And it is said that we have an internal compass with which we feel the attraction of the Earth's magnetic poles, and that is why we allow ourselves to be attracted either by the North or the South.

¿Did you know that migratory birds can fly up to 4,000 kilometers on a single journey?
Every spring and autumn, we witness the spectacle of millions of birds embarking on a long and risky journey from their breeding grounds to their wintering areas and back.
This annual migration mainly happens at night, when the winds are gentler, and the moon and stars serve as guides.
Birds tend to follow established migration routes. Usually from north to south and with places to rest and recharge along the way. Many bird species share routes and must face harsh weather conditions, dehydration, hunger, and predators to get where they want to be.
In Colombia, the country of birds, we welcome these migratory birds.
Get to know the migratory birds that come to our country:
Water birds depart and arrive at lakes, lagoons, and wetlands, where they find fish, crabs, aquatic insects, and other animals for food, as well as plants that grow along the edges.
Land birds, like us, live in forests or open areas such as pastures and crops, depending on our preferences. Some of us even reach towns and cities. In all these places, we find food like fruit, insects, and flower nectar.
Shorebirds are a mix of land and water birds, as they live along the edges of lakes, lagoons, or the coast. There, they find food like crabs, worms, insects, and snails.
Las aves migratorias no tenemos un reloj en nuestras manos (¡perdón, en nuestras patas!), pero existen señales que nos indican que debemos partir en busca de condiciones apropiadas para vivir durante los meses del invierno de los extremos del continente. Por ejemplo, los insectos empiezan a desaparecer y nos vamos quedando sin alimento, y las temperaturas empiezan a bajar. For the return, we don't have such clear signs, but there’s an inner clock within us that tells us it's time to go! We feel an overwhelming urge to find a mate and raise a family, and we know it's better to do that in a place with less competition from other birds, like in the tropics. So then we just take flight.
Some birds fly incredibly long distances, like the Arctic Tern, which almost flies around the entire globe, covering 40,000 kilometers and making it the bird with the longest migration route in the world.
We birds can travel for weeks or even months! For example, a peregrine falcon takes the air from September to November to travel from Canada to Argentina! But some birds make migrations that last only a few days within the same country they are from.
Actions that contribute to the safe passage for our travellers:
Conserve and restore important natural areas for birds.
Minimize the use of pesticides and light pollution at night.
Promote awareness about the importance of migratory birds.
Advocate for laws that protect their habitats and migration routes.
Work with global organizations for their conservation.
Use window stickers and other methods to prevent birds from colliding with glass structures.
Help with the monitoring and study of migratory birds.
Black-and-white Warbler (Mniotilta varia) Hello, I’m Tilda, the Black-and-white Warbler. I am the bird with the most eye-catching stripes of the whole forest. You’ll see me hopping among branches searching for tasty insects. I love being in large trees. Some might confuse me with the male plumage of the Setophaga striata, but don’t be fooled! My black-and-white striped pattern and playful behavior make me unique. So, if you see someone moving from branch to branch with style, it’s probably me.

Blue-winged Teal (Spatula discors) I’m Spatu, the duck with blue patches on my wings! Males like me, have a white moon-like spot in front of their eyes. We can't forget the black bill that gives us a sophisticated look! Females, on the other hand, are plainer: they are darkish brown with a pale spot next to their beaks. I like freshwater lagoons, lakes, and swamps, but during winter, I love to visit brackish waters (Mix between fresh and seawater). I eat a little bit of everything: plants, insects, and those delicious aquatic crabs.

Many of us migratory birds have an incredible spatial memory that allows us to remember our migratory routes and important landmarks along the way. This ability is crucial to our survival and success during our migrations. Upon returning to our breeding or wintering areas, we can remember precise routes and specific locations where we found food or shelter in the past. This spatial memory helps us navigate efficiently and locate the best places to feed and rest, even after being away for months.
Reinita de Canadá (Cardellina canadensis) ¡Hola, soy Lina la Cardellina! Me encanta destacar con mi plumaje, que es de un elegante gris azulado arriba y un vibrante amarillo abajo. No puedo olvidar mis llamativos anteojos amarillos y mi collar de rayas negras que le da un toque especial a mi look. Mis piernas son de un bonito anaranjado pálido. Las hembras como yo tenemos un collar más sutil comparado con el de los machos. Me encuentro felizmente en vegetación baja, especialmente en esos bosques húmedos y matorrales que tanto me gustan. ¡Ah, y me encanta anidar en el suelo, donde me siento más segura! Mi dieta está llena de insectos. Y no solo eso, ¡soy una de las aves migratorias que recorre mayores distancias! Durante el invierno, voy a disfrutar de la calidez de Suramérica.

About two weeks before our migration, we started eating much more than usual in order to obtain large reserves of fat that gives us energy. Along the way, we sometimes stop at some places for several days to gain a little weight and replenish our strength, or we make short stops to rest and eat a little, and then keep going until the end!
During our migration, some of us used air currents to save energy. We take advantage of favorable winds and rising thermal currents to rise more easily and travel long distances with less effort. Thermal currents are columns of warm air that rise from the earth when the sun heats the surface. By landing on these updrafts, we can rise without having to constantly flap our wings, which reduces energy expenditure. In addition, favorable winds help us maintain a constant speed and cover long distances more quickly. This strategy of flying on air currents allows us to maximize our efficiency during long migratory journeys, conserving our energy and optimizing our resources to meet the challenges of migration.

Throughout our migrations, we can communicate with each other through specific calls. These vocalizations help us coordinate our movements, maintain group cohesion during flight, and warn of possible dangers. Our vocalizations during migration are a multifunctional tool that helps us coordinate our movements, maintain cohesion, warn of danger, and strengthen our social interactions. This communication is essential for the success and security of our immigration journeys.

During our migration, we experience a significant increase in our metabolism. This allows us to accumulate large fat reserves before the trip, which we use as a source of energy during the flight. This process, known as "hyperphagia", means that we overeat to store the necessary fat.
Raptors or birds of prey can fly over mountains, taking advantage of air currents created by the hot sun during the day. Or fly over rivers and lakes, travelling across the continent.
Prothonotary Warbler (Protonotaria citrea) Hi! I’m Citri, a charming warbler who lives in humid forests.

Some species of migratory birds, such as nightingales and songbirds, migrate primarily at night. This nocturnal behavior allows us to avoid predators that are active during the day and also reduces the risk of dehydration and overheating. Flying under the cover of night helps conserve our energy and maintain a more stable body temperature, which is crucial for long non-stop journeys. In addition, the lower activity of other animals and the quietness at night offer us a safer and less stressful environment during the trip.

Raptors or birds of prey can fly over mountains, taking advantage of air currents created by the hot sun during the day. Or fly over rivers and lakes, travelling across the continent.
Shorebirds usually fly at night to avoid predators and to eat during the day. Their route follows inland or coastal water, or islands and sometimes they fly over the Atlantic Ocean!
Water birds also fly between continents, seeking out lakes and rivers. And songbirds, like us, fly between continents, looking for forests where we can find food.
Migratory birds orient ourselves in various ways on our trips. During migration, our navigation skills are amazing. For example, when we fly at night, we look at the stars to stay on track. The constellations act as celestial maps that help us maintain the correct direction. During the day, the sun is our main reference; We know how to adjust our flight based on its position in the sky. Those of us who generally travel at night, like warblers, guide ourselves by seeing the position of the stars, as sailors do.

In our migration, some of us fly non-stop to cross spaces as large as the Gulf of Mexico, which is a thousand kilometers long. This type of continuous crossing is an impressive challenge, since we need to stay in flight for many hours without rest. Our ability to make uninterrupted flights of this magnitude demonstrates the incredible resilience and adaptation we have developed to face the long distances of our migrations.

During the day, the sun is our main reference; We know how to adjust our flight based on its position in the sky, allowing us to stay on the right course throughout the journey. By combining the information we get from the sun with the signals we perceive from the Earth's magnetic field and other visual reference points, we achieve precise and effective orientation. We also remember mountains, lakes, rivers, deserts and even cities! And it is said that we have an internal compass with which we feel the attraction of the Earth's magnetic poles, and that is why we allow ourselves to be attracted either by the North or the South.
