A broad-tailed hummingbird can
flap its wings 70–80 times per
second, allowing it to hover and
perform acrobatics. The bird, which
weighs just 3.5 g (0.1 oz), needs a
lot of energy to fuel its flight. This
comes from the nectar it drinks.
A hummingbird’s
heart beats around
500 times a minute
at rest, increasing to
1,300 times a minute
when hovering.
NECTAR POINTS
In return for a flower’s nectar,
most hummingbirds pollinate plants,
picking up pollen from one flower and
taking it to the next. Some visit up
to 2,000 flowers a day. However,
the wedge-billed hummingbird drills
into the nectar bulb at the base of a
plant, getting nectar without pollen.
