Figure lower
Printed “Icterine Grosbeak”
Mycerobas affinis
- Certain
- Checked against the engraved caption
- Finches, Euphonias, and Allies · Fringillidae
Why
Lower figure: Gould's 'young male', grey on the head and throat with an olive-yellow body, is a female Collared Grosbeak, as he concedes in the V.23 text after Captain Pinwill pointed it out. Sharpe cites V.22 under the Black-and-yellow Grosbeak 'excepting the lower figure, which is H. affinis' female.
