Robin Migration Update: March 30, 2004
Today's Report Includes:
News: Singing Robins Across Canada’s Border!
“Finally, at 7 am March 28 I heard and saw my first Robin this spring.
A lonely guy at the very top of our birch tree. A lot of birds have come
back this week, reports Dominique from our Northern Observation Post way
up in St. Sauveur Des Monts, PQ, Canada. Indeed, the first full week of
spring brought many reports of first robins, waves of robins, and singing
robins. Can you see a clear migration pattern on the maps? Where waves
and individuals have been reported, the first robins are beginning to
claim territories and start singing. The robin migration continues its
steady march northward, and many of you shared exciting news for this
maps are snapshots of the migration on March 28, but the maps change every
minute on our new MapServer. Almost as soon as you report your first robin,
your data will show on the MapServer. Please remember to report your sightings,
and then watch the migration’s progress on the MapServer between
our Journey North Robin Reports!
“The Robins have arrived! They must've come in Friday
night with the warm front. Friday afternoon it was 69 degrees and we had
our classroom windows open for the first time. Saturday morning when I
woke up I heard Robin vocalizations everywhere, including the "cheery
cheer up" song. During the weekend I saw Robins bouncing around on
lawns all around the school. Our tulips were up this week too. What a
great spring week this has been.” (Ms. Karelitz, Moharimet
School, Madbury, NH)
In Haliburton, Ontario, Canada, Louise put her baby monitor
to a new use: “My trusty outdoor baby monitor did it again, alerting
me to the presence of robins this morning (March 28)--at least six, all
flying overhead with their red breasts gleaming in the rising sun.”
In Woburn, Massachusetts, Mrs. Cerullo’s grade 7 classes
have been practicing identifying the robins' vocalizations. By March 18
several students had reported hearing the typical Robin Song. “Even
though we have 8 inches of snow on the ground, we believe that Spring
Waves of robins are moving north, too:
“I heard several robins throughout the neighborhood. Since I am
blind and do all my birding by ear, I can't say I saw them but they are
here. Two of them were singing on territory and most of the rest were
scolding. Although this was not the first robin of the season for me,
it was the first real wave from all I can tell.” (Cerise
from St. Cloud, MN on March 19)
Journaling: Where Was Your Robin Yesterday?
Did you know that all these robins migrate at a speed of about 30 miles
per hour? Robins can migrate during day or night. They average 38 miles
per day, but some days they don't migrate at all. Other days they can
go many times that distance.
- On the first day of spring last week,
when night was exactly as long as day everywhere on the planet, how
far did a night-flying robin travel if it flew for 6 hours?
- When your first robin of spring arrives,
look on a map and see if you can guess what town it might have left
the night before. Then write in your science journal: "The robin
that landed this morning in my town of ______ probably flew ___ km/miles
on a 6-hour journey overnight. If it flew straight north, it may have
traveled all the way from _____(name of town km/miles directly to the
south). If it flew northwest, it may have traveled all the way from
______(name of town km/miles directly to the southeast) If it flew northeast,
it may have traveled all the way from (name of town km/miles directly
to the southwest)."
Journey North Students
Make Headlines in Oradell, New Jersey
Tracking springtime’s first robins with Journey North is not only
fun, but sometimes it gets you some press! NewsHouse reporter Dru Sefton
interviewed principal Scott Ryan and some K-6 students in the school’s
weather club, who are busy reporting new robin sightings on the school
announcement system each morning. Meet the students and hear what they
say. You may learn surprising things about Journey North, too!
The Adventures of Robin Hood
Do you think all robins look pretty much alike? Journey North writer Julie
Brophy knows how careful observers can tell robins apart. Julie recognizes
her robin, and each spring she looks for him. She’s been rewarded
FOUR years in a row. Yes, Julie’s “Robin Hood” has returned!
Banding studies show that many robins return near their birthplace every
year. This is the fourth year Robin Hood (RH) has returned to the same back
yard. After seeing her first Robin, why do you think Julie wait for a while
to decide if she's actually seeing Robin Hood? What signs or behaviors help
Julie to be sure it's RH? Why is Julie careful to place Robin Hood’s
mealworm snacks under an outdoor table with chairs? See Julie’s photos
and field notes and you’ll find out!
If you liked reading about Robin Hood,
you’ll like Julie’s field notes about another robin buddy.
(Robins look pretty much the same for their entire adult lives. How do
you think Buddy recognized Julie when she wore different clothes every

Video Clip and Journaling Question
Did you know that you’ve already seen Robin Hood for yourself? The
two video clips in our March 16 report starred Robin Hood. Here’s
another of Julie’s video clips, also taken last summer.
First, see these comments from Journey North’s Robin Expert Laura
Erickson to guide your viewing:
“This robin is running on the pavement. Notice how he runs a short
distance, searches, and runs again. Do you notice him poop? Healthy, well-fed
robins eliminate their wastes several times every hour. Their intestines
are much shorter than most mammal intestines, so they eliminate wastes
as quickly as they produce them. Small rodents must do the same thing,
as anyone who has ever held a gerbil, hamster, or pet mouse knows! It’s
even easier to see the robin poop in this slow-motion version (video 2)
of the same video clip.”
- If all robins poop so much, how do they
keep their nests and babies clean?
or Looking? Challenge Question #6
Mrs. Kloewer from York (Nebraska) Middle School wrote
on March 10: “The first big wave of robins has finally arrived!
The lawns are full of big, fat robins. We think the earthworms are up,
too, because the robins seem to be watching the ground carefully and picking
On March 16, Marne in Michigan wrote: “The sun's
first peek over the horizion was greeted with the joyful bubbling music
of our group of robins. After that first burst of rippling notes, the
robins are quietly stalking the lawn in front of our big shop.”
These comments make us wonder how you’ll answer:

Temps and Robins: This Week’s Isotherm Map and Observation
“Early in the morning on March 27th, we heard the robin's familiar
song and went looking for him - and found him in our yard about 12:45
pm flying parallel to our creek. We checked our isotherm reading for the
week and our average temperature for this week was 31.9 degrees!”
(Luke, Sixth Grade Homeschooler in Chelsea, VT.) Hooray
for Luke! Readers, what do you think of those results? Are YOU tracking
the isotherm with YOUR robins.
- Has the 37-degree isotherm moved in
the past two weeks?
- Have robin movements shown a pattern
similar to the change in the 37-degree isotherm? (Compare with the migration
maps at the top of the Web report.)
- Do the changes in where the 37-degree
isotherm is correspond to where robins have been singing?
For instructions to calculate the isotherm in YOUR region, see:

Are You Ready
to Play Ask the Expert? Challenge Question #7
Wayne Dwornik, our Northern Observation Post in Lethbridge
AB, Canada, heard his first robin sing on March 22! But Wayne has a question.
He hoped a robin he saw in his back yard was spying out his robin nesting
box. “We've had this box for at least 8 years now and never a nest,
... yet.” Wayne wonders what suggestion we have for his nesting
box. We thought YOU would like to play “Ask the Expert” and
do some research. How would you answer Wayne’s Question below?(Hint:
See our Robin lessons page.)
Challenge Question #7:
“What advice would you tell Wayne about the use and placement
of robin nesting boxes?”

Early Bird Contest
Update: Challenge Question #4 Reminder
Challenge Question #4 asked, "When do you think the first robin will
be spotted in Anchorage, Alaska (61.22 N, 149.90 W)? Do you think it will
arrive with the 36-degree isotherm?" Several of you have sent your
entries, and the contest is still open because students at Sand Lake Elementary
in Anchorage are still waiting for their first robin! Have you sent us your
prediction for Challenge Question #4?
a Good Territory: Discussion of Challenge Question
Last time we asked you to “List factors that make for (1) a GOOD
robin territory and (2) a POOR robin territory” after reading our
lesson about recognizing a good territory from above. Three cheers for
Ferrisburgh (VT) Central School second-graders Lindsay, Tim, Jordan,
Autumn, Shane and Grant AND fourth-grader Mallika from Harrington School
in Lexington, MA. All did their research and good, thorough thinking
to bring you these answers:
A good robin territory would have:
- Food--a lot of earthworms and berries
and fruit trees for an emergency (cold weather, no worms yet)
- Water. Robins like ponds, lakes, and
streams, or some source for fresh water...
- Safety--not a lot of predators, not
a lot of loud noises, not have too many people around
- Shelters or places to build nests,
like near roofs or in pine trees
(The second graders said, “We have seen robins build nests in
milk cartons on porches or in the letters on a big store sign.”)
- Open spaces so the robins can see what
- LAWN-Robins like grassy green lawns
so they can have a good view to watch out for predators and for Earthworms...
- Other robins nearby--so they can mate
and make friends...
All of you agreed that a POOR robin territory would have few food sources;
be very noisy and busy; have no lawns or water sources; have no safe
places to nest; have a lot of places for predators to hide; and have
bigger birds like hawks and other predators.
Now you’re ready to answer the next question!
The Early Bird
Gets the _________?
You might have said worm, but after studying the sections above, you may
also know that an early bird also gets. . .the best territory!
Why is a good nesting territory so important to a robin? First, robins
need safe places for building nests and laying eggs. After the eggs hatch,
the territory has to provide food not only for ravenous nestlings, but
for the parents as well. In two weeks in the nest, each young robin may
eat 14 feet of earthworms, and earthworms aren't even their main food!
How can parents keep up with the demands of such a hungry brood? Hunting
and feeding takes every waking hour. In the northern latitudes of Alaska,
feeding time may extend to 21 hours a day. A robin makes an average of
100 feeding visits to its nest each day. With that schedule, there's no
time to go far for food--another reason why a good territory is important.
