The occurrences
We gathered 2600 occurrence localities, after removing redundant ones
(Supplementary Material B). Most occurrences were from the Atlantic
Forest (48%), followed by the Amazonia (21%), Cerrado (17%), Caatinga
(8%), Pampa (4%), and Pantanal (3%; Fig. 1; Table 2). The
Southeastern Region,
~11% of the Brazilian territory, was represented the
best with 34% of the records, while the Northern region,
45%< of the Brazilian territory, only provided 25% of the
records. Both the Atlantic Forest and Cerrado were the most diverse
biomes harboring records for ~81% of the species each,
followed by the Amazonia (67%), Pampa (76%), Caatinga (57%), and
Pantanal (48%).
For several species, we found records far outside the geographical or
ecological limits traditionally reported in the literature. For example,
the spectacled owl (Pulsatrix perspicillata ) is frequently split
into an Amazonian population and another from the Atlantic Forest, but
there are records for all the remnant biomes except the Pampa.
