It has been reported in the lower Atrato Valley from the Rio Salaqui and from the Alto del Buey region in the Baudö Mountains (De Schauensee 1948—1952). A. cajanea is widespread east of the Andes and in Middle America but is replaced from the central Chocö region to the south by its close relative Aramides wolii, a form also recorded from the Alto del Buey in the central Chocö (Fig. 27). This, however, does not prove sympatric breeding of these two allied species. A detailed study of their zone of contact is needed to clarify their interrelationship and taxonomic status. A. wolfi has a somewhat heavier bill and a more richly colored back, which is chestnut brown or olivaceous brown in wolfi and olive in cajanea. *) Locality records shown on this and the following maps are taken from Wet- more (1965—1972) for eastern Panama and from De Schauensee (1948—1952) and Haffer (this publication) for northwestern Colombia. Mountains above 1000 m elevation are in black.
