They do not seem to work over the outer leaves as does zonates in such vegetation. I can see no special use of the bill, whil is rather long & narrow.

(zonates feeds in flight & has a long slender bill, suggesting, behalf, that the slender bill & focacies is an adaptation for probing, most likely in the tiena fruit or fruit of other ecoti - At our last encounter with this species we found evidence of this type of feeding. ) In a fairly clear area adjacent to a dense stand of mesquite & tiara and about 20 feet from a stream but there is a nest placed 12 feet or so up in a large mesquite - I flushed 3 birds from this nest about 1 hour before sunset.
