Grassland Conservation 

Funds raised from the 2021 Colorado Birding Challenge were donated to Bird Conservancy of the Rockies to support two of their ongoing efforts.

  1. Restoration of degraded grasslands in northern Mexico to help provide suitable habitat for wintering Colorado grassland birds whose populations are declining due to decreasing habitat
  2. Expand the Motus network by building a tower to help track the migratory routes, breeding sites, and wintering locations of threatened grassland bird species. This information will help focus future conservation efforts.
