Migration: What's
Happening Now & What to Watch For |
What's
Happening Now
Robins began to sing this week way up north in
Canada at latitude 49N:
-
"Not
an April fool joke to stand outside and hear this welcome
sign of spring," reported
a happy Mariaopolis observer
on April 1. She offered this translation
of her first robin's song: "Yes,
we're here and thank you for not cleaning up all the
fruit on your
apple
tree
last
fall." Mariapolis, Manitoba
- We heard (and saw) our long awaited first male robin this morning
while walking to school (830 am). It's clear and sunny and still
cold (snow still on the ground). I heard him first and the kids
were thrilled when I pointed him out at the top of a tall tree.
Winnipeg, Manitoba
Farther
south, but at higher elevations, people in the Rocky Mountain
states of Montana, Colorado and Utah haven't yet reported
singing robins. It's colder in the mountains the higher you
go, so
robins and
other signs of spring arrive later. But singing robins should
happen soon:
-
After
a night of heavy rain, a Lewiston, Montana observer reported
on April 1: "As I walked to school,
the sidewalks were covered with earthworms. Good news
for the large flocks of robins seen in the past two weeks."
Watch
the map in coming days and you'll see that singing
robins will reveal the temperature patterns of our continent.
With each passing week, we'll hear reports of robins are
singing at higher latitudes and
at higher elevations.

What
to Watch For
Predict
when the first robins will reach interior Alaska!
At
latitude 62 north in Shageluk, Alaska, students at
Innoko River School officiate Journey North's "Early
Bird Contest." Teacher Joy Hamilton reports:
"No
sign of the 'gah-non-da-doy' (robins) yet. We're still locked
in snow and ice here."

| An
Author Shares: "American Idol Robins" |
Meet author Don Grussing, who grew up with six kids in a crowded house.
He loved escaping outdoors, where he heard only
the
birds.
Mr. Grussing
wrote The Seasons of the Robin. The story
follows a young male robin's
first year of life from struggling to hatch, through his first migration,
returning home, establishing a territory, finding a mate and starting
the cycle anew.
Mr. Grussing shares a story just for us:
American Idol Robins by Don Grussing
Female
robins don't sing the territorial song, but very many, if not most,
male Robins seem to be paying
attention to the judges on TV’s
"American Idol" show.
They
take the common Robin song, and make it their
own. They add phrases, warbles and sounds that make it
possible for us to distinguish one Robin’s song from another’s.
Often these modifications of the songs involve many repetitions of parts
of the song
that seem to be favorites of the singer. This can help you tell
one robin from another.
Try
This! Listen to the robins sing and see how long
it takes for you to learn the differences
between the songs of your
neighborhood robins. Robins sing most often in the morning
or before a rain, but often will burst into song at any time of the
day (and sometimes night)
during the breeding
season.
Any Robins At Mr. Grussing's Yet?
We asked and he replied: "I have seen several passing through, but
not one musical note. We still need
more snow to
melt in this neighborhood to make it good habitat for robins. Oh, and
the
waxwings ate all the crabapples and buckthorn berries early in the winter."
Coming next week:
Another story just for us!

Don Grussing shares a birding adventure with his grandkids.

Mr. Grussing wrote in his book's preface:
" Once you experience
the world through a robin's eyes, I hope you'll look at every wild thing
with
new
appreciation and respect for what they accomplish by living." |
