Listen to part of a lecture in a biology class.
Now usually when we talk about birds flying long distances, we’re discussing seasonal migration.
But there’s some species that fly long distances not as part of a migration but as part of their regular foraging for food.
A great example is the albatross, albatross are seabirds that nest on islands and forage for food out in the open sea.
And you have one species that forages an average of a thousand miles from its nest.
And I read in another study where one albatross left a chick in its nest and went out in search of food.
And by the time it got back to the nest, it has flown nine thousand miles. Yes, Bob?
But why don’t they just build their nest closer to their food supply?
I mean, for one thing, they must burn up a lot of energy flying back and forth and also the parents are gonna have to be away from the nest that much.
Aren’t the chicks gonna be pretty hungry most of the time?
OK, good question. The chicks are capable of going for long periods of time without food,
which works out nicely since as you point out, they may not get to eat that often.
