Scansores \Scan*so"res\, n. pl. [NL., fr. L. scandere, scansum,
   to climb.] (Zo["o]l.)
   An artifical group of birds formerly regarded as an order.
   They are distributed among several orders by modern
   ornithologists.

   Note: The toes are in pairs, two before and two behind, by
         which they are enabled to cling to, and climb upon,
         trees, as the woodpeckers, parrots, cuckoos, and
         trogons. See Illust. under {Aves}.
