We couldn't really find any way to confirm our findings without observation
of males and females, but we used this question as a great way to research
a subject we could not observe. Here are some responses from Bobby 's 2nd
and 3rd graders in Crested Butte Colorado

The Birder's Handbook, by Ehrlich, tells us that males robins mate
with one female a season but not necesarily the same one every year

I found information on the computer and it said robins only mate with one mate.
My computer says very few males mate with the same females.
Usually robins mate with one female a year. My parents told me!
Robins mate with one, I checked on Grollier computer.
Robins mate almost with one girl. I learned that from my teacher
WE used Computers, interviews and bird books to fin our answers.
Do robins change territories every year? Why do juveniles have spots on
their breasts? When do the worms come up? We have lots of puddles between
huge areas of snow and mud but no worms. Even a few green grassy areas but
no worms?? How long do robins babiesa stay with their mom? how long do
babies stay in their shells before they crack?

We love Journey North! It makes us think like scientists!
