| The beak, however, is not so straight or strong
as in the typical woodpeckers;
but it is strong enough to bore into wood;
and I may mention, as another illustration of the varied habits of the tribe, that a Mexican Colaptes has been described by De Saussure as boring holes into hard wood in order to lay up a store of acorns for its future consumption! Hence the
Colaptes of La Plata
in all the essential parts of its organization
is a woodpecker,
and until recently was classed in the same typical genus. Even such
trifling characters as its
colouring, the harsh tone of its
voice, and undulatory flight, all told me plainly of
its close blood-relationship to our common species; yet it is a woodpecker,
as I can assert
not only from my own observation,
but from that
of the accurate Azara, which never climbs a tree! |

| In certain other districts, however, this same woodpecker, as Mr. Hudson states, frequents trees, and bores holes in the trunk for its nest.
