1.
Which of the following is the reason for birds to migrate south?
Correct Answer
C. Food Supply
Explanation
Birds migrate south primarily because of the availability of food supply. As the weather gets colder in their current location, many of the food sources for birds become scarce or inaccessible. By migrating to warmer regions, birds can find a more abundant supply of food, such as insects, fruits, and seeds, which helps them survive during the winter months. This migration pattern allows birds to ensure their survival and maintain their energy levels by finding suitable food sources.
2.
How far will birds travel to find a warmer climate?
Correct Answer
E. 1000 miles or more
Explanation
Birds will travel 1000 miles or more to find a warmer climate because they migrate to avoid harsh winter conditions and to find better food sources. Many bird species have the ability to fly long distances, and they rely on their instincts and environmental cues to navigate and find suitable habitats. Some birds, such as the Arctic tern, can even travel up to 44,000 miles round-trip during their annual migration. Therefore, it is not uncommon for birds to travel long distances, including 1000 miles or more, in search of a warmer climate.
3.
Which US state has the most migratory birds?

New Jersey is located along the Atlantic Flyway, a major migratory route for birds traveling between their breeding and wintering grounds. Maryland is also situated along the Atlantic Flyway and has a range of habitats, including coastal areas and marshes, which are attractive to migratory birds.
4.
Which of these is recognized as the highest-flying migratory bird?
Correct Answer
A. Bar-headed geese
Explanation
Bar-headed geese are recognized as the highest-flying migratory bird. These geese are known for their exceptional ability to fly over the Himalayan mountains, reaching altitudes of up to 29,500 feet. They have specialized adaptations that allow them to survive in the thin air at such high elevations, including larger lungs, more efficient oxygen transport, and unique wing structures. This enables them to undertake their long-distance migrations, crossing the highest mountain range in the world.
5.
The _________ can fly more than 49,700 miles each year, racking up more miles than any other migratory bird.
Correct Answer
C. Arctic tern
Explanation
The Arctic tern can fly more than 49,700 miles each year, which is more than any other migratory bird. This bird is known for its impressive long-distance migration, traveling from its breeding grounds in the Arctic to its wintering grounds in the Antarctic. This extensive journey allows the Arctic tern to accumulate a significant number of miles, making it the bird that racks up the most miles during its migratory flights.
6.
Migratory birds remember and return to the same location where they were born. State true or false.
Correct Answer
A. True
Explanation
Migratory birds do have the ability to remember and return to the same location where they were born. This behavior is known as philopatry and it helps them navigate long distances during their annual migrations. By returning to familiar breeding grounds, they can find suitable nesting sites and maximize their chances of reproductive success. This behavior is observed in many species of migratory birds, making the statement true.
7.
Name the bird that can fly for nearly 7,000 miles (8 days) without stopping.
Correct Answer
B. Bar-tailed godwit
Explanation
The correct answer is Bar-tailed godwit. Bar-tailed godwits are known for their incredible long-distance flights. They undertake one of the longest known non-stop flights of any bird, flying nearly 7,000 miles without stopping. This impressive feat takes them around 8 days to complete.
8.
What is the name of the smallest migrating bird?
Correct Answer
A. Hummingbirds
Explanation
Hummingbirds are the correct answer because they are the smallest migrating birds. These tiny birds are known for their ability to hover in mid-air and their rapid wing beats, which allow them to fly backwards and upside down. They undertake long-distance migrations, with some species traveling thousands of miles between their breeding and wintering grounds. Despite their small size, hummingbirds are capable of impressive feats of endurance and navigation, making them the smallest but mighty migratory birds.
9.
The birds migrating from Neotropic areas in Central America and South America are called __________.
Correct Answer
B. Neotropic birds

Neotropic birds refer to the bird species that are native to the Neotropics, which is a region of the Americas that includes Central and South America. Therefore, the term "Neotropic birds" accurately describes the birds migrating from these areas.
10.
Which of these items do birds need when landing in yards after migration?
Correct Answer(s)
A. Food
B. water
Explanation
Birds need food and water when landing in yards after migration. After a long journey, birds need to replenish their energy and hydration levels. They require food to refuel their bodies and water to quench their thirst. Eggs are not mentioned in the question and therefore are not necessary for birds when landing in yards after migration.
