to wings.Red limited to a few spangles on crown and throat. (see photos) |

Similar
species and
how were they eliminated: |
Red-naped Sapsucker is similar, however juveniles
mostly molt into first cycle plumage before migrating, and therefor juvenile
Red-naped appear much like adults with mostly black white and red plumage, very
little to no mottled brown juvenile feather left after this molt by October 1st.
Red-breasted Saspucker juvenile are much darker sooty brown on the head and breast, and also molt into fist cycle plumage before October My understanding is any Sapsucker in full juvenile plumage this late in the fall can only be a Yellow-bellied |
Previous
experience with this & similar species: |
I seen 5 Yellow-bellied Sapsuckers, adults and juveniles in Utah, I've also seen many Red-naped Sapsuckers, at least 3 hybrids of the two, and 2 Red-breasted Sapsuckers, and several hybrid Red-breasted X Red-naped, and I've also seen 1 Red-breasted X Yellow-bellied hybrid in Utah. Very familiar with Sapsucker ID. |
