Hi all,
According to E.M. McCarthy¹s Handbook of Avian Hybrids (2006, OUP), the
following combinations with Little Corella occur (except for x sulphurea
apparently all in the wild):
Cacatua sanguinea [Little Corella]
x galerita [Sulphur-crested C.]
x leadbeateri [Major Mitchell¹s C.]
x pastinator [Western C.]
x roseicapillus [Galah]
x sulphurea [Lesser Sulphur-crested C.]
x tenuirostris [Long-billed C.]
x Callocephalon fimbriatum [Gang-gang C.]
