Anuran advertisement calls are life history traits associated with sexual selection and reproduction, and they play an important role in premating isolation mechanisms between species. Comparative bioacoustical analyses of these calls can be useful for taxonomic purposes. Phylogenetic relationships within the genera Pseudis are controversial, especially those related to P. platensis, which is often considered a full species or a subspecies within P. paradoxa. The advertisement call of P. platensis has not been described in detail; therefore, call comparisons of these two conspecifics have not been possible. In this study, we describe the advertisement call and diel activity pattern of P. platensis in the Brazilian Pantanal and compare the calls of P. platensis and P. paradoxa to elucidate whether acoustical parameters may help resolve the present uncertain taxonomic treatment. The advertisement call of P. platensis lasted 0.21 ± 0.01 s and consisted of a short series of 8.05 ± 0.69 distinct pulses (9.34 ± 2.94 ms of pulse duration). The vocal activity of the species was largely restricted to a few hours after dusk (7–11 p.m.), which is inconsistent with the diurnal and nocturnal calling behavior described for other Pseudis congeners. The advertisement calls of P. platensis and P. paradoxa were similar in note duration, number of pulses per note and dominant frequency. The geographic variation of calls within species was similar to that found among species. This bioacoustical comparison does not provide new insights into whether P. platensis should be considered a distinct species.

Tinamous (Tinamidae) are a group of Neotropical birds for which little information is available. The Undulated Tinamou (Crypturellus undulatus) is one of the most wide- spread species but also declining. Due to its secretive habits, ecological knowledge regarding the species relies on few anecdotal descriptions. We used automated re- corders to monitor the vocal activity of the species over an annual cycle at four sites in the Brazilian Pantanal. We provide a description and analyze the diel and seasonal patterns of the calling activity in this species and provide new ecological informa- tion. The daily cycle showed two significant peaks in calling activity during the early morning and late afternoon, in agreement with the vocal behavior common among tinamous. The species was vocally active throughout the year, but it was significantly higher during September–October and March. This suggests that the breeding period of the Undulated Tinamou in the Brazilian Pantanal extends from September to April. After the months with highest calling activity, there was a strong decrease in activity, which might be related to the silent behavior of male tinamous during incubation. The seasonal pattern and breeding period identified for the Undulated Tinamou in the Brazilian Pantanal are in agreement with those observed in previous studies carried out with other Crypturellus species. The use of automated recorders was found to be a useful method for monitoring the calling activity of this secretive group of birds and might be useful in the assessment of future population trends in this and other declining tinamous.
