*It is the ultimate goal of HawkWatch International to maintain the sustainability of the organization and the integrity of our data. Therefore, in light of the recent economic downturn and other trends in conservation science funding, we have made the difficult decision to operate fewer raptor migration monitoring sites. As of the 2010 fall season, we will no longer be performing fall migration counts in the Wellsville Mountains in Utah and Lipan Point in Arizona. Lipan’s sister site, Yaki Point, will continue operations. In Montana, our partner Montana Audubon, will manage the monitoring at the Bridger Mountain site and share the data with HWI. Some banding operations may be scaled back as well.
We would like you to know that we appreciate your ongoing support, and welcome your comments and questions.

Satellite Tracking Program
HWI began our Raptor Satellite Tracking Program to help determine how and where to most effectively tailor our raptor conservation efforts. Since the program's inception in 1999, we have worked to address a variety of questions toward this end, including:
- Do individual birds use specific flyways consistently across seasons?
- What are the origins of migrant raptors flying above our migration monitoring sites?
- What are the different species' patterns of habitat use?
Detailed tracking maps for many of the birds outfitted to date can be accessed by following the links at the bottom of this page. Due to (rapidly improving) technological limitations, the program has heretofore focused on three of the larger raptor species, including: Golden Eagles, Red-tailed Hawks, and Northern Goshawks.
HWI has tracked 98 birds in the course of the program's duration. View the Deployment Table detailing the number of birds deployed each year and from which location. You can also view summaries and maps of each of their movements by following these links:
