Spring starts today! Robins were on the move last week with record high temperatures in many places. More than one-third of the week's "first" sighting reports came from Canada, and our song map reports also spread north. This week's Read-with-Me slideshow celebrates what robins do in spring.

This Week's Update Includes:

News: What's Happening Now & What to Watch For
What's Happening Now
NOAA reported that nearly 2,500 warm weather records were set last week. Your robin sighting reports told us that robins are pushing into Canada; 14 of the week's 50 of the first robin reports were north of the US-Canada border. Singing robins were reported farther north, too. However, there are still no signs of spring in snow-covered Alaska.
  • Michigan, March 15: I reported seeing a single robin just a week ago. Now they are everywhere! :)
  • New Jersey, March 19: Mr. Sabatino's second grade class at Somerville Elementary School heard a robin singing the typical song today. We went into our ecology center with our laptop and compared what we were hearing to the song on the Journey North website. It was a perfect match!
  • Winnipeg, Manitoba, March 16: After an incredible week of spring weather in Winnipeg, we heard and saw our first beautiful robin. This is very early for us (last year it was April 4).
What to Watch For
Notice how male robins act when near each other as they arrive. Also watch for females, who arrive on territory a few days to a week behind the males.
  • Indiana, March 16: A pair of robins in our schoolyard were flying from tree to tree and squawking. Several students were "dive-bombed" but not hurt when robins came close to their heads. Old nests were noticed in the [evergreen] trees.

Slideshow: Hello, Robins! Hello, Spring!
When robins are in our backyards, citizen scientists observe and wonder: How long will the robins stay? What food will the robins find? Where will the robins build a nest?

This week's Read-with-Me booklet is the perfect way to welcome spring and explore the essential question: What are robins doing in our backyards?

Turn your own backyard observations into Read-with-Me books to share with friends.

Research Robin-Speak: What Are They Saying?
Robins depend on their voices to locate friends, establish territory borders and warn of enemies. Listen to six distince robin vocalizations, and you'll be able to decode robin-speak when you hear it!
Latest Maps: Where Are Robins Now?
These maps show where people have reported robins and earthworms. Patterns emerge as citizen scientists report their observations. What do you notice this week as you compare where robins are singing with first robin sightings?
