The short profile

The story behind it

A ruby-throated hummingbird's wings beat around 50 times per second, creating the humming sound that gives the family its name and allowing it to hover in place, fly backwards, and even fly upside down for a moment. To fuel this fast flight, it drinks flower nectar almost constantly and also eats tiny insects and spiders for protein, visiting up to a thousand flowers a day. Its heart can beat over 1,200 times a minute during flight, one of the fastest heart rates of any animal. Each autumn, many ruby-throated hummingbirds fly non-stop across the Gulf of Mexico, a journey of about 800 km that takes around 20 hours, fuelled only by fat stored before the flight. Despite their tiny size, they remain widespread and common.

Questions children ask

How fast does a hummingbird's heart beat?

A ruby-throated hummingbird's heart can beat over 1,200 times a minute during flight, among the fastest of any animal. This huge heart rate powers the rapid wingbeats it needs to hover in place.

Can hummingbirds fly backwards?

Yes, ruby-throated hummingbirds are one of the few birds that can fly backwards, and they can also hover and briefly fly upside down. Their unique figure-eight wing motion gives them this unusual control in the air.

How far do ruby-throated hummingbirds migrate?

Many ruby-throated hummingbirds fly non-stop across the Gulf of Mexico each autumn, a journey of around 800 km that takes about 20 hours. They build up fat beforehand to fuel the entire crossing without stopping.
