Eurasian Oystercatcher (Far Eastern)
SCI Name: Haematopus ostralegus osculans
osculans
L. osculans, osculantis  kissing (i.e. close together, almost united, allied)  < osculari  to adhere closely, to kiss  < osculum  kiss  < dim. os, oris  mouth (cf. oscillans, oscillantis  swinging  < oscillare  to swing).
● “CHALCITES OSCULANS.  ...  I have applied the term of osculans to this species, because in it are united to a remarkable degree the characters of the genera Cuculus and Chalcites; but as those of the latter genus predominate, I have retained it therein.” (Gould 1847) (Chalcites).
● "HELIANTHEA OSCULANS, Gould.  ...  This new species is about the same size as H. violifera, but differs from that bird in having a stouter and longer bill, by the spot on the forehead being larger, and green instead of blue; by the tips of the tail-coverts and tail-feathers being tinged with olive-green, and by the breast being of a more brilliant green, and destitute of any crescentic greyish-white mark across the chest." (Gould 1871) (Coeligena).
● "RAMPHASTOS OSCULANS.  ...  Ramph. culminato, Gould, quam proxime accedit." (Gould 1835) (syn. Ramphastos vitellinus x R. cuminatus).
● "SERICORNIS OSCULANS, Gould.  ...  Intermediate in size between S. frontalis and S. humilis."(Gould 1847) (syn. Sericornis frontalis mellori x S. f. rosinae).
