Brown-capped Rosy-Finch monitoring in Colorado

Hello everyone. 

 

If you visit the high country of Colorado in the summer or have a winter feeder, please keep your eyes out and report sightings of banded and unbanded Brown-capped Rosy-Finches (BCRF).

 

To obtain a better understanding of movement patterns and connectivity of breeding populations, the Bird Conservancy of the Rockies in collaboration the Denver Museum of Nature and Science, the University of California at Santa Cruz, Colorado Parks and Wildlife, the US Fish and Wildlife Service, and the US Forest Service are placing color bands on BCRFs at wintering and breeding grounds.

BCRFs have declined by as much as 95% over the past 50 years and unfortunately we don’t know why.

BCRFs nest in alpine habitats above 11,000 feet and distribution is almost entirely limited to Colorado.  In summer and fall they feed on seeds and insects on snow fields and in alpine tundra. In winter BCRFs are common at high elevation bird feeders only moving to lower elevations for short periods during winter.

  If you observe a BCRF, please report:

  • ·         Date
  • ·         Time
  • ·         Location (latitude/longitude in decimal degrees from phone or GPS) or a detailed description
  • ·         Number of birds
  • ·         Bands- If the bird is banded, record the color (silver, gold, blue, purple, red, and green, see below) and which leg (left or right) the band is on. Birds have been banded with a single color band on one leg and a silver-colored numbered aluminum (silver) band on the other. Some birds may have only one numbered aluminum band.
  • ·         Sightings can be entered into eBird, on the Rosy Finch page at www.CitSci.org, or using the CitSci app available for iPhones and Android devices.
  • ·         Photographs of the birds and the general location.
