4: Sitting Tight
female Ruby-throated Hummingbird is sitting tight! She must incubate
her eggs for about two weeks. She'll spend about 75% of the daylight
hours incubating and sleep on the nest at night. What would
you look at and think about if you had to sit in a nest on a tree
branch most of the day?
What do you think the female does during the day when she's not
incubating eggs? (Answer below photo.)
The female leaves the nest for short periods (as little as 15
seconds) to feed on nearby nectar and insects. If the weather
is warm, she will spend more time away finding food. If it's cold
and wet, she may not leave the nest at all. Her instinct tells
her to stay and keep her eggs warm!
