Highlights: A Clear Arrival in Texas This Week!
The leading edge of this spring's migration has clearly arrived in Texas! Our map shows a line at 30N, the same latitude as Austin. But look where the monarchs were last year at this time
they had already reached 35 north and had moved into Arkansas. (See March 17, 2006 map.)

"Conditions are still wet and cool through most of Texas," says Mike Quinn of Texas Parks and Wildlife.

What does spring migration look like? When the monarchs leave Mexico they fill the sky. By the time they reach Texas they have dispersed over miles and miles of space. You can usually count the number you see on one hand.

"It's not dramatic, actually, what you see," says monarch biologist Dr. Bill Calvert. "You never see too many at once. You may see one or two an hour. That would be a good spring migration." More >>

Where Will They Go Next? Predicting the Patterns of Migration

The monarchs are pouring out of Mexico now and trickling into Texas. Where do you think they will appear next? New Mexico? Oklahoma? Arkansas? (You might be surprised!)

Why do the monarchs travel where they do? What drives the pace and direction of the migration? By tracking the migration "live" we can help answer questions like these. Let's watch carefully this spring and see what we can learn.

  • In what general direction do you think the migration will move? Will the monarchs go north, east, west or spread out equally in all directions? Give reasons to explain your thinking.
