Ten fun facts

  1. that its average wingspan is one and a quarter inches, which is closer to the wingspan of a butterfly than a bird.

  2. that on a typical day it eats up to half of its own body weight in nectar, small insects, and spiders.

  3. that its nest is a cup just one inch wide, built ten to sixteen feet above the ground in small branches.

  4. that each nest is used only once, and the female builds a completely new one for every single brood she lays.

  5. that its eggs are the size of coffee beans and the female lays at most two of them at a single time.

  6. that it lives up to seven years in the wild and can reach up to ten full years when kept in captivity.

  7. that it has been described as the smallest known dinosaur, because living birds are actually surviving theropod dinosaurs.

  8. that researchers have observed it visiting ten different plant species, nine of which are native only to the island of Cuba.

  9. that the flowers it visits are odorless, with long narrow petals, bright colors, and very diluted sugary nectar.

  10. that the female incubates the eggs alone for twenty-one days, then takes care of the chicks for eighteen more days.

The quiz answers

The first one is the question printed in your book: here is the answer. The other four are extra.

Question 1 of 5★ this one is in your book

How much does an adult male weigh?

Question 2 of 5

How many times per second does it beat its wings?

Question 3 of 5

Where does this species live?

Question 4 of 5

How many eggs does the female lay at a time?

Question 5 of 5

What does it build its nest with?

Try it yourself

Experiment 1

Mark two and a quarter inches on a ruler to see the total length of an adult male. Compare that small size with the length of your thumb.

Experiment 2

Clap your hands as fast as you can for one second and count the claps. The wings of this bird beat two hundred times in that same time.

Experiment 3

Draw a circle one inch wide on paper to match the diameter of the tiny nest. Try placing two coffee beans inside to see how they fit.
