| Where
Are American Robins in February 2008? |
Our
Winter Robin Round-up results are in! These "snapshot"
maps show what you told us: From Alaska to Florida and California
to Nova Scotia, robins are feeding, flocking, and flying. A few
robins are already singing! Are you surprised?
Robin
migration can seem a bit confusing. As we begin the season, find
out some facts about robin migration and learn why we make three
different maps to track their travels:

Your
observations made us say WOW! Take a look:
- Thousands
of robins have swooped into our little neighborhood this afternoon.
What an incredible sight! (Palm Coast, FL)
- I had to slow my car when turning on to my
street; the little one-lane
road, as well as
the yards on both sides of the street were covered with robins.
It has been a very strange weather year. I wonder how this affects
the migration.
(Woodbine, GA)
- I've never really seen robins here before, but in the past
week I've had a hundred give or take every day feeding in my yard. They
are feeding in Camphor trees on berries. They cover the trees and ground.
Eating
as much as possible is the goal. (Tallahassee, FL)
- Lots of robins showed up between big winter storms here; males fighting
in the bushes; berry bush in the front yard was picked almost clean just
this morning. (CA)
What brings
the robins? An age-old theory about robin migration says that robins
arrive in an
area when
the average temperature is 36 degree F. Is it accurate?
Why not
test the theory yourselves? >> |
To test whether robins
seem to travel with average temperatures of 36 degrees, first find out
when robins generally return to your region each spring. Begin the study
about a month before their average arrival date. |
"Since
early January 2008, we have observed thousands of robins roosting in
our neighborhood. Every morning after sun-up, they head south and are
gone
all day. They roost in pine and oak trees near our house."

Question: What would a robin say? |
Explore! American
Robin Dictionary >> |
"The Robins I heard were giving
the Peek, Tut, and Zeeup calls," reported
an observer this week. Can you translate robin-speak? Dig
into our Robin Dictionary for
help. Then name the call that a robin would use to "say" each
of these things:
- "Aren't
these berries delicious? What a great day. Off we go into the wild
blue yonder!"
- "Everybody
watch out! Here comes a hawk!"
- "Hey,
sweetie! Check out MY yard! Wouldn't this be a great place to raise
babies?
Wouldn't I make a great father to your babies?"

| Getting
Ready: Can You Name That Tune? |
| Song
is the sign we're looking for. "I
heard him before I saw him. It was a male, at the top of a holly tree,
singing
his
heart
out! (Definitely
singing the territorial robin song.)" So
far, only a few robins have begun to sing. Get
ready so you can be as certain as this observer! Our sound recordings
help you recognize six common vocalizations robins make. Then listen
again
to
the same
calls in scrambled order and see if you can…
