“…A peak of calling activity during the breeding season has been previously found in several tinamous (Lancaster 1964a, 1964b, Solano‐Ugalde et al . 2018) and the proposed role in mate attraction is in agreement with the role proposed for nocturnal vocalizations for a large number of diurnal passerines (Amrhein et al . 2002, Celis‐Murillo et al .…”

“…Previous studies of tinamous indicate that their vocal activity peaks during the breeding period (Lancaster 1964a, 1964b, Solano‐Ugalde et al . 2018), suggesting that the study of seasonal changes of nocturnal vocal output may be useful to understand the causes of the nocturnal vocalizations of this group of birds. The call of the Undulated Tinamou, its only known vocalization (Pérez‐Granados et al .…”

Some diurnal birds vocalize at night but the reason for this has seldom been studied. We monitored the nocturnal vocal activity of the Undulated Tinamou Crypturellus undulatus from June 2015 to May 2016 at three recording stations in the Brazilian Pantanal. We tested whether an index of nocturnal vocal output (number of vocalizations automatically detected) of the species varied over the monitored annual cycle and whether it was related to night temperature and moon phase. The annual pattern of nocturnal vocal output was unimodal, with high vocal activity during September and October (49.9% of the total calls detected) and very low vocal output from January through June (8.5% of the total). The unimodal pattern found suggests that nocturnal vocal activity might be related to mate attraction rather than to territorial defence, for which a more constant pattern would have been expected. The percentage of the moon illuminated was positively associated with nocturnal vocal activity, probably related to the elevated light level on moonlit nights. Nocturnal vocal activity was not associated with minimum air temperature. Nocturnal vocal output was positively associated with vocal output during the preceding night, but not with vocal output during the preceding day, suggesting that it was not directly associated with diurnal calling. This is the first study showing a complete annual cycle of nocturnal vocalizations for a diurnal bird species. Our study provides new evidence regarding the function of and the reasons for nocturnal vocalizations in a diurnal non‐passerine bird and has important implications for continued study of reproductive behaviour in tinamous. Further research should examine whether courtship display is associated with nocturnal vocalizations in this and other species.

“…The suggested breeding period of the Undulated Tinamou (September–April) is similar to that indicated for the closely related Yellow‐legged Tinamou ( Crypturellus noctivagus ) in Venezuela (August–April, Friedmann & Smith, ) and for the Little Tinamou ( Crypturellus soui ) in Costa Rica. Tinamous from other genera seem to breed mainly at the end of the rainy period (March–April) (Lancaster, ; Negret et al, ; Solano‐Ugalde et al, ). The observation of the maximum calling activity of the Undulated Tinamou in September–October and March can be related to the period when males establish territories and seek mates (Lancaster, ), while the decrease in calling activity in the following month might be due to the silent behavior of incubating males, a phenomenon found in other tinamous (Lancaster, ).…”

“…This behavior makes these species an interesting group for studying the breeding ecology of birds. However, there is a lack of knowledge on the basic natural history of most tinamous (Cabot, ), and even knowledge regarding their breeding ecology is restricted to anecdotal or captive breeding data (Brooks, ; Solano‐Ugalde, Ordóñez‐Delgado, Vits, & Freile, ). This is because tinamous are cryptic, shy, and secretive Neotropical birds with mainly crepuscular and nocturnal activity.…”

Vocal behavior of the Undulated Tinamou (Crypturellus undulatus) over an annual cycle in the Brazilian Pantanal: New ecological information

2019

Tinamous (Tinamidae) are a group of Neotropical birds for which little information is available. The Undulated Tinamou (Crypturellus undulatus) is one of the most widespread species but also declining. Due to its secretive habits, ecological knowledge regarding the species relies on few anecdotal descriptions. We used automated recorders 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 information. 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.Abstract in Portugese is available with online material.

Reportamos un registro altitudinal inusual de Zorro Andino Pseudalopex culpaeus (Carnivora: Canidae) obtenido con cámaras trampa a 1353 m en el piedemonte suroriental andino, Copalinga Ecolodge, provincia de Zamora Chinchipe, Ecuador. Este constituye el registro altitudinal más bajo de esta especie en el país y el primer reporte para una región en la que no existía evidencia previa de su presencia. Como información de referencia asociada, presentamos el listado de los mamíferos de pequeño a mediano tamaño registrados en esta localidad.AbstractWe report an unusual altitudinal record of the Culpeo Pseudalopex culpaeus (Carnivora: Canidae) registered by trap cameras at 1353 m in the southeastern Andean foothills at Copalinga Ecolodge, province of Zamora Chinchipe, Ecuador.
