Subject: [obol] Extralimital blackcapped chickadees
Feather wear neatly explains away the birds l saw last June in La Grande.
They were all devoid of eye-stripes, and equally deficient of any color
hinting "warm". There were many, in extensive thorn scrub just south of the
city limits, a habitat that seemed perhaps appropriate for an outlier
species. Literature search did not offer me a subspecies of Black-cap with
gray flanks. Lars
