DEFINITIONS

MICRATHENE
(Strigidae; Ϯ Elf Owl M. whitneyi) Gr. μικρος mikros  little; genus Athene Boie, 1822, owl; "MICRATHENE Coues, nov. gen.   ...   Of small size, being among the most diminutive of known Owls.  TYPE. Athene Whitneyi, Cooper.  With the size and general aspect of Glaucidium, this genus differs greatly from it as follows: The bill is smaller, weaker, less strongly hooked and dentulated.  The wings are much longer, and the tail much shorter.  The tarsus is unfeathered except for a short space superiorly.  The claws are so small and weak as to be hardly more than insessorial rather than raptorial in character.  The proportions of the tarsus and toes differ decidedly.  Nor has it much in common with Athene, except the partially denuded tarsi; the relative proportions of the tarsus and toes to each other being quite different in the two genera; Athene having the middle toe and claw about two thirds the tarsus, instead of fully as long.  The claws of Athene are very long, acute and little curved.  While both genera are very long winged, there is a decided difference in the shape of the wing; that of Athene being much the most pointed, in consequence of the greater elongation of the first and second primaries.  I think it more than probable that Micrathene is a truly arboreal genus, like Glaucidium, thus differing radically in its habits from the species of Athene." (Coues 1866).
Synon. Micropallas.
