Poecile atricapillus x gambeli Status: No accepted records (but see Comments). Comments: Although Mountain and Black-capped Chickadee apparently hybridize “extensively in Rio Grande valley of central New Mexico” where neither species is common, hybridization is only occasional in the large area of overlap of the ranges of the two species where each species is common […]
