Peregrine Falcon Falco peregrinus

Records generalized to full township/ranges; true population density thus much thinner than symbolized. Seriously underrepresented in BBA due to inaccessibility of Cascade nest sites and non-disclosure policies designed to protect this recovering species. Nesting has expanded almost exponentially since Peregrine's removal from Endangered Species List in 1999, with pairs now inhabiting most western Washington cities. Nested in downtown Seattle for first time in 1994 and has returned each year since; Seattle population had risen to at least four pairs by 2004, after close of atlas period.
