Nesting reports increased this week and spring robin behaviors thrilled observers in much of the robins' range.

Gathering and Building by Amy Evoniuk

Robins are switching from winter flocking behavior to singing on territory and gathering nesting materials where spring weather is warmer. Eight of the Northern Observation Posts have reported robins! However, winter's grip isn't gone. Record-breaking amounts of snow linger in Canada's Maritime provinces, and returning robins find the frozen, snowy ground blocking their access to food. Luckily, many observers put out fruits and berries to help them. Hurry, warm weather!
