The subspecies of central and eastern Brazil, and adjacent regions in Paraguay, Bolivia and Argentinia, is thaumantias, but it is not clear whether our local form belongs to this taxon. The distribution maps in Schuchmann 1999 and Grantsau 1988 do not include Ceará.
Synonyms: Trochilus guainumbi PALLAS 1764; Trochilus thaumantias LINNAEUS 1766
Figure 1. This bird has some white around the eye, but it does not exhibit the white postocular and infraocular stripes that are typical for the species, according to the figures and descriptions in Mata et al. 2006 (p. 278) and Schuchmann 1999 (pl. 56 and p. 591). I found fig. 1 in table 28 of Grantsau 1988 similar to our bird, except for the color of the bill. But Grantsau's figure depicts the nominal subspecies, which has a different range (northern Brazil, Venezuela, etc.).
Thus, the identification is still a little uncertain.To top of page
Figure 2. This individual (which is the same as in fig. 1) has a maxilla with interesting colors: red at the base, then black, then red again, and finally a black tip.To top of page
