2010 Spring Migration Begins

Island Girl, our last tagged migrant peregrine and the "Earthquake Queen", began her journey north sometime after 1300Z on Tuesday, 13 April. That translates to the morning hours in Chile.

This year, she departed one day after her start last year. She left her area just north of the Putu Dunes and covered about 275 km (171 miles) on the first day and, as usual, generally followed along the Pacific coast.

She flew past many of the places we have worked in or driven through several times including San Antonio, Casablanca, Valparaiso, Vina Del Mar and Quillota. She appears to have crossed the Pan-American Highway just north of Calera before continuing on to roost in the foothills of the coastal range.

Looks like she slept on the north slope of a mountain ridgeline (Cerro Cuajo) in a dry forest only about 2.65 km (1.65 miles) from the highway and south of La Ligua, a place we know well.

She slept inland about 21 km (13 miles) from the beaches of Maitencillo.

As a reminder, many of our satellite transmitters have failed after about a year of service. This unit originally went online on 15 March 2009 after Kathy caught her a second time.

We are hoping that this will be one of the longer lasting units but only time will tell.
