5 Tiny Animals With BIG Migrations

The video explores the remarkable migrations of small animals relative to their body size. It covers the Ruby-Throated Hummingbirds' nonstop flight across the Gulf of Mexico, hoverflies' migration over the English Channel, monarch butterflies' navigation across North America, desert locusts' swarming behavior, and the global journey of wandering glider dragonflies. These creatures use various strategies like high-altitude winds and internal compasses to achieve their long-distance travels, highlighting their ecological importance and the challenges they face.

What is the primary reason Ruby Throated Hummingbirds migrate such long distances?

• To avoid competition with other birds

• To find new nesting sites

• To find warmer weather and food

• To escape predators

How do hoverflies manage to migrate across the English Channel despite their small size?

• By using high-altitude winds

• By flying at night

• By traveling in large groups

• By resting on water surfaces

What is the ecological role of hoverflies in the UK?

• They are a primary food source for birds

• They are predators of small mammals

• They help in seed dispersal

• They pollinate crops and control aphid populations

What unique navigation method do monarch butterflies use during their migration?

• Listening to ocean waves

• Tracking the scent of flowers

• Using Earth's magnetic field

• Following the stars

What triggers the desert locusts to switch to swarm mode?

• Crowded conditions

• Rainfall

• Lack of food

• Change in temperature

How do wandering gliders manage to travel such long distances?

• By hitching rides on birds

• By using large wings to glide on air currents

• By swimming across oceans

• By burrowing underground

Why is the wandering glider considered a single global population?

• They have a unique mating ritual

• They can survive in any climate

• There is regular gene flow between different locations

• They are the only dragonflies that migrate
