Monarch Watch Tagging Results, 2007

Neva Carmichael, Jamie Pakkala and Ann Vance tagged one hundred twenty-one monarchs. Three tags were unused; one was spoiled. (I tagged the truck.)
Fifty-three of the one hundred twenty-one were males;
sixty-eight were females.
All were tagged and released on site.
One hundred five were tagged at Hawk Cliff or near vicinity. Sixteen were tagged else where.
It appeared that we missed the peak of the migration in the 2 weeks before the demonstrations.
We have had four recoveries, all at El Rosario, Mexico. Three were tagged at Fingal Wildlife Management Area and one at Hawk Cliff, all in September, 2003. The first recovery was on February 29, 2004, the second on January 20, 2005, and the third and fourth on March 7, 2006. The Monarchs had flown about 3,152 km.
