DEFINITIONS

FORMICARIUS
(Formicariidae; Ϯ Rufous-capped Ant-thrush F. colma) Mod. L. formicarius  of the ant  < Med. L. formicarium  ant-hill  < L. formica ant. The antbirds received their name from the habit of a few species of trailing ant armies and feeding on the insects thus disturbed or put to flight; “This bird inhabits South America  ...  in the neighbourhood of large ant-hills, on the inhabitants of which it chiefly feeds, as do several other species; many sorts of which unite together into bands: but what is observable in this species, it is seldom seen except one in a flock of the others, or at most a pair. These birds for the most part keep on the ground, and appear less active than those which it keeps company with” (Latham 1783). The ant-thrushes are shy, terrestrial birds, much more often heard than seen and sometimes occur on the periphery of ant swarms; "700.  1.Palikour BUFF. VIII. p. 238. BRISS. Ornith. o. LINN. o.
