Observation details

Continuing bright individual found by Alex and Sharon. Very active among the locations previous shared by other birders. It was feeding actively the entire time whenever I was able to locate it. Compared with TOWA, BTNW shows higher contrast on it's wings, more solid yellow tone on the face and yellow across its vent. BTNW gives me a distinct vibe of black, white and yellow with little green involved.
