Monitoring Avian Productivity and Survivorship (MAPS)
System monitoring is conducted to collect data on existing populations and habitats of covered species to determine their status, distribution, density, migration, productivity, and other ecologically important parameters. The Monitoring Avian Productivity and Survivorship (MAPS) program helps to accomplish these objectives with several of the LCR MSCP covered avian species as well as other resident species. There is a MAPS site at two of the LCR MSCP restoration areas, Cibola Nature Trail, near Blythe, CA, and Beal Lake, near Needles, CA. The MAPS season is broken down into ten 10-day banding periods that begin on May 1st, the breeding season for most species along the lower Colorado River. Various MAPS sites have operated along the LCR since 2000 by Reclamation.
Each site has ten 8.5 ft by 39 ft (2.6 m by 12 m) mist nets set up in various habitats throughout the area. Using these mist nets, birds are captured and are banded with a numbered U.S. Fish and Wildlife Service aluminum band. Data is recorded that indicate species, age, breeding status, and condition of each bird. Covered bird species such as Sonoran yellow warbler, Arizona Bell’s vireo, and summer tanager are also color banded in unique combinations that allow observers to identify individual birds. Resighting efforts help establish residency of these covered species during the breeding season.
