Please see this spring's potential pair/ nesting information below. Note that all of the pair information indicates breeding behavior and potentail nesting based on the adults' behavior. Pairs are listed under the land management unit where birds are suspected to be nesting. All condors are identified below by WingTagNumber (StudBookID#_Sex_YearHatch). The wing tag is what you will be able to use to identify the birds in the wild when observing them! The Stud book ID # is unique to each individual condor.
