News: Migration Surges North
Migration surges—full steam ahead
Weather conditions were in place for the migration to surge forward last week. The northern tier states and southern Canada reported over three and a half times more "first" rubythroat sightings than the week before. The map animation gives you an idea of the strength of the migration.

Will they stay?
Will your hummingbirds be staying for the season, or just making a pit stop on their way further north? Time and behavior will tell. "I saw my hummingbirds, Harold & Henry today for the 1st time this season," reports Sue Scribner in Danbury, CT. "Harold always flies to the south treeline of my yard and Henry always flies to the north treeline. I knew earlier today that they finally arrived because a couple of feeder tubes went down quite a bit today."

Other Hummer Species Moving
As the rubythroats are moving north and west, the rufous hummingbirds are marching eastward. Almost along a line, they are sweeping into Montana, Idaho and northern Utah despite the cool temperatures. "First rufous spotted. Still having frosty mornings here," writes a reporter from Emmett, Idaho.

Calliopes, black-chinned, black-tailed and annas hummer sighting reports continue to come in as the birds make their way north and west into the mountains of the west.

Surge in first sightings: 3-4 times more than previous week!

Slideshow: A Hummingbird Nest

A female hummingbird has been busy collecting soft and strong materials for her nest. Now she is about to lay tiny, jellybean-sized eggs in her nest. You're invited to peek inside the nest and welcome the nestlings into the world. Study each photograph and describe what you see happening.
