Journaling Question: Growing Needs
"What
are two different reasons why the number of feeding trips increases sharply
when the babies are about a week old?"
When baby wrens are tiny, they simply can't fit as much food in their
tummies as they can when they've grown bigger. That explains why they
get more food the second week than they did the first week. But why the
sudden sharp increase? At that point the babies have feathered out enough,
and have enough control over their body temperatures, that their mother
no longer needs to incubate them to keep them warm during the day. So
now she can spend a lot more time searching for food for the babies. And
based on those hungry wren mouths we saw in one of the wren videos, we
bet the babies are glad!
