Migration News: Robin Chorus Spreading

What's Happening Now

Robins are now singing in 31 states and 3 Canadian provinces, according to Journey North's citizen scientists. At this writing, Pennsylvania leads with the most songs (13 reports), followed by Michigan (9). Meanwhile, observers in the U.S. midsection are hit with another snowstorm. They (and their robins) wonder what happened to spring, while farther north, observers are celebrating their backyard robins:

  • Pennsylvania: "Heard the first Robin territorial calls this afternoon! Yay! They're setting up shop!"
  • Alberta, Canada: "Good-bye winter and helloooo spring!!! Finally! We spotted our first Robin on our backyard fence this morning. We are so ready for springtime!"
  • Minnesota: "I heard the distinct Peek n Tut of my first spring robin! It took me a minute to locate him in the spruce tree. We still have 2 feet of snow cover and below freezing temps. This (Mar. 23) is my latest first sighting."

What to Watch For:

Signs of nesting
Where females have begun to arrive, nesting is next:

  • Texas: "We have a pair of robins that are staying close to the yard. They have been observed in our birdbath and sitting in the trees surrounding the area. They are singing and have been observed gathering sticks from the yard."

The Robin Checklist for Spring Observations tells what to watch for as this exciting season unfolds. Put nesting behaviors on our new map by knowing what to report. Then click "Nesting Behaviors" as the reporting category to share the good news!
