FIGURES 24–25 in A new species of Formicivora antwren from the Chapada Diamantina, eastern Brazil (Aves: Passeriformes: Thamnophilidae)
FIGURES 24–25. Calls of Formicivora grantsaui sp.nov. (ASEC 10512): 24, a transition call between a series of alarm calls (see Fig. 9) and scolding calls; 25, a typical scolding call. Notice that the last note of the call in Fig. 24 is prolonged in a harsh sound, like a short version of the scolding call (window function Blackman, amplitude logarithmic, filter bandwidth 533 Hz, overlap 93.75%, FFT size 16384 points).

(MNRJ 44149); male F. rufa collected at the same locality (MNRJ 44151); female paratype of F. grantsaui sp. nov. (MNRJ 44150); and female F. rufa collected at the same locality (MNRJ 44153); 3, ventral view; 4, lateral view; 5, dorsal view.

FIGURES 9–12 in A new species of Formicivora antwren from the Chapada Diamantina, eastern Brazil (Aves: Passeriformes: Thamnophilidae)
FIGURES 9–12. The alarm call shared by: 9, Formicivora grantsaui sp. nov. (ASEC 10549); 10, F. r u f a (ASEC 3186); 11, F. acutirostris (MBBR s/no.); and 12, F. g r i s e a (ASEC 3011) presents a similar first note with a rapid descending frequency modulation followed by a second part, having up to three additional notes, whose structure is more variable among the several taxa. In F. grantsaui this final part most often has two very short notes (but see Figs. 13–14), while in the other species it always has only one note (window function Blackman, amplitude logarithmic, window size 533 samples, overlap 96.2%, DFT size 16384 points).
FIGURES 19–20 in A new species of Formicivora antwren from the Chapada Diamantina, eastern Brazil (Aves: Passeriformes: Thamnophilidae)
FIGURES 19–20. Loudsong of: 19, Formicivora grantsaui sp. nov., showing six notes from a much longer series (ASEC 10549); 20, F. r u f a recorded at the same locality, showing a complete song phrase (ASEC 10539). Notice the pace about 7 times faster in F. r u f a. Inset in each figure is an enlargement on the time scale (same scale for all) to show more comparative detail (window function Blackman, amplitude logarithmic, window size 533 samples, overlap 96.2%, DFT size 4096 points).
FIGURE 26 in A new species of Formicivora antwren from the Chapada Diamantina, eastern Brazil (Aves: Passeriformes: Thamnophilidae)
FIGURE 26. Two consecutive scolding calls of Formicivora grisea from coastal Bahia, Brazil (MLNS 35741) (see Figs. 24–25) (window function Blackman, amplitude logarithmic, window size 533 samples, overlap 96.2%, DFT size 32768 points).
FIGURES 15–18 in A new species of Formicivora antwren from the Chapada Diamantina, eastern Brazil (Aves: Passeriformes: Thamnophilidae)
FIGURES 15–18. Territorial (duet) call of: 15, Formicivora grantsaui sp. nov. (ASEC 10545); 16, F. r u f a (ASEC 2818); 17–18, variants of F. g r i s e a (ASEC 2990 and 3012 respectively). Notice the shorter call with distinctive ascending/descending frequency modulation of notes in F. grantsaui (window function Blackman, amplitude logarithmic, window size 533 samples, overlap 96.2%, DFT size 32768 points).
FIGURES 21–23 in A new species of Formicivora antwren from the Chapada Diamantina, eastern Brazil (Aves: Passeriformes: Thamnophilidae)
FIGURES 21–23. Distress call of: 21, Formicivora grantsaui sp. nov., two consecutive whistles (ASEC 10615, from the holotype); 22, F. g r i s e a, two consecutive whistles (JMCS 07/39); 23, F. r u f a, a complete trill (ASEC 3184). All recordings made from mist-netted birds. (window function Blackman, amplitude logarithmic, window size 533 samples, overlap 96.2%, DFT size 16384 points).
