Wood Thrush Monitoring with Geolocators

During the first four days of December 2011, a team led by Dr. Kevin Fraser of York University's biology department successfully attached geolocators to 10 individual Wood Thrushes (Hylocichla mustelina) captured at El Jaguar Reserve in Jinotega. The geolocators will allow researchers to recapture the birds next winter and determine where in the U.S. and Canada the birds bred, and should provide useful data about the migration routes these birds use between their breeding and wintering grounds.

The same weekend, El Jaguar carried out its monthly MoSI monitoring of overwintering migrant bird species. Among the more interesting birds captured were the resident Ruddy Woodcreeper (Dendrocincla homochroa) and the migrant Philadelphia Vireo (Vireo philadelphicus), photographed by Georges Duriaux.
