Florida to Alaska and California to Canada, robins are home. They're hunkering
down to the serious business of making new little robins. See
what's in a day's work for those parents, and find

Roller coaster temperatures in the North keep robin spotters
on the lookout. Once the robins get settled in they lose
the job ahead of raising a family. Explore and learn about
the 14 days from egg to fledgling robins. Or, build a nest
platform for the robins. It will keep them safe and let you
watch the amazing process.
Few sighting reports may indicate that migration has slowed. Robins that already
reached the end of the road are busy with the next stage in their
cycle. "Hey, the robins are starting building the nest!! It is wonderful!" wrote
an excited Quebec observer. How do Robins divide the chores? Investigate: Would

Look at spring temperature patterns in North America and compare
them to the map of singing robins. In what ways are they similar?
Two robins stopped to rest during migration last Thursday
morning in my neighborhood. They hopped from branch to branch
and tree to tree, but never flew. What can you learn by looking
closely at their pictures?
Your exciting reports tell us that robins are still arriving,
still moving through parts of the continent in huge waves,
and now singing in more places. Females arriving mean it's
time for our photo study so you can tell them apart. Compare
the earthworm map and robin maps. How do robins find those
worms? A scientist's fascinating experiments shed light on
the answer. See which NOPs are still waiting for robins.
Robins continue to spread out across the map. See how a clever
robin observer has helped robins find food after a heavy snowfall.
Study and compare temperature and robin maps to see if an
age-old theory is accurate this season. And keep your eyes
and ears on alert for the first robins in your area this spring!
Spring has arrived, at least by the calendar. While distribution
hasn't changed a great deal in the past week, our map shows
that abundance has. More robins are singing on territories.
Why is claiming and defending a good territory so important

wondered about robins that came there to breed, and are
showing up earlier than ever before.

This week find out about our Northern Observation Posts (NOPs).
Learn about the 22 spotters that wait and watch for the robins

before they arrive in each place? Search for clues to help
you predict when the red-breasted robin will show up at each
No big push northward occurred this week, but the map is filling
in. Robins are singing in a few spots, even though temps are
freezing! What does a robin need from its habitat? Find out
if yours is ready. How does a robin learn its song? Our interview
with Dr. Aborn reveals answers. Investigate robin behavior
with photo studies and take your turn as the expert.
Just a quick update today to give you the latest maps and
data to study. Robins are coming! Where are robins singing
this week? Compare this map with the one showing robin sightings.
How are they different and alike? Look for patterns and predict
where the first singing robin will be reported next week!
From Alaska to Florida and California to Nova Scotia, robins
are feeding, flocking, and flying. A few robins are already
singing! Surprised? Learn why we make three different maps
to track their travels. Play "Name That Tune" to
be sure when your robin arrives. Dig into "Robin-speak"
to recognize what robins say with their calls. Get the basics
of Song and Temperature this week and you'll be ready to track
robins all the way home!
Where are the robins spending
this 2008 winter? Let's find out before the spring migration
begins! We'd like to know if you have robins over-wintering
in your town. Go outside and look for robins. Ask everybody
you know — near or far —
to help you look for robins. Then report your sightings
by February 18. It's the Winter Robin Round-up for 2008.
