No Squabbling Here
baby birds squabble and bicker. Baby hawks and herons sometimes
even hurt each other. But not hummingbirds!
Q: Why don't baby hummingbirds bicker as some other baby
(Answer below photo.)
Bickering takes energy, and makes it easier for predators to notice
a nest. Nestlings that fight usually belong to species that hunt
for limited food. When a mother hawk catches a mouse, she might
not catch another for several hours, or even a whole day. So if
the most aggressive baby gets the food, it is more likely to survive
than the meeker babies. But hummingbird mothers are sure to find
enough food for both their babies, so there's no need for the
babies to waste energy arguing.
