to Challenge Question #3: Timing is Everything
earlier said that whoopers get rewarded for migrating at the right
time. We asked you to be alert for new information in Tom Stehn’s March
24 report to help with this question: “What
determines the best time for whooping cranes to migrate? Give statements
to support your answer.”
for Marcus, who carefully read Tom’s
report! He made a good case with supporting statements
based on his research:
F. (Homeschool in Mount Airy, Maryland. Grade 6)
best time for Whoopers to migrate is determined by experience, and then,
natural selection helps ensure that the birds who made the
best choices survive. The birds leave partly in response to degraded
habitat conditions in their wintering grounds, such as diminishing
food supplies. They also watch for weather that seems favorable
their journey. The weather during migration and upon arrival at their
destination can affect them either positively or negatively. Bad
weather during migration can slow or stop their progress. If they
early, and the weather is still severe, this can lead to death. If
they arrive too late, there may not be any good nesting spots for
even if they do nest, there may not be enough food for their young.
All these variables make it difficult for Whoopers to accomplish

to find food.
