“…Eastern Whip-poor-wills (Antrostomus vociferus) and Common Poorwills (Phalaenoptilus nuttallii) have also been reported to leave eggs unattended at dawn and dusk when adults exchange incubation duties (Cink 2002, Woods et al 2005.…”

“…Brigham et al (2011) indicated that only female Common Nighthawks brooded during the day, but provided no information about brooding at night. Woods et al (2005) reported that both male and female Common Poorwills brood, but provided no details concerning the contributions of each sex. Similarly, Cink (2002) indicated that both male and female Eastern Whip-poor-wills brood young, but provided no information concerning the relative contributions of each sex.…”

“…Temperature and wind speed were included for all diurnal avian species (U. S. Geological Survey, ). The nocturnal avian species models included variables for wind speed and cosine of the lunar phase because vocal availability may be improved on moonlit nights (Woods, Csada, & Brigham, ). The coyote model also contained the cosine of the lunar phase because this species may be more vocally active at the new moon (Bender, Bayne, & Brigham, ).…”

Temporally adaptive acoustic sampling to maximize detection across a suite of focal wildlife species

Acoustic recordings of the environment can produce species presence–absence data for characterizing populations of sound‐producing wildlife over multiple spatial scales. If a species is present at a site but does not vocalize during a scheduled audio recording survey, researchers may incorrectly conclude that the species is absent (“false negative”). The risk of false negatives is compounded when audio devices have sampling constraints, do not record continuously, and must be manually scheduled to operate at pre‐selected times of day, particularly when research programs target multiple species with acoustic availability that varies across temporal conditions. We developed a temporally adaptive acoustic sampling algorithm to maximize detection probabilities for a suite of focal species amid sampling constraints. The algorithm combines user‐supplied species vocalization models with site‐specific weather forecasts to set an optimized sampling schedule for the following day. To test our algorithm, we simulated hourly vocalization probabilities for a suite of focal species in a hypothetical monitoring area for the year 2016. We conducted a factorial experiment that sampled from the 2016 acoustic environment to compare the probability of acoustic detection by a fixed (stationary) schedule versus a temporally adaptive optimized schedule under several sampling efforts and monitoring durations. We found that over the course of a study season, the probability of acoustically capturing a focal species (given presence) at least once via automated acoustic monitoring was greater (and acoustic capture occurred earlier in the season) when using the temporally adaptive optimized schedule as compared to a fixed schedule. The advantages of a temporally adaptive optimized acoustic sampling schedule are magnified when a study duration is short, sampling effort is low, and/or species acoustic availability is minimal. This methodology presents the opportunity to maximize acoustic monitoring sampling efforts amid constraints.

“…Durante la incubación y en ambas especies estudiadas la mayoría de las salidas nocturnas se registraron al anochecer y al amanecer. Los adultos dejaron los huevos desatendidos en promedio durante 37 (AC) a 40 min (AÑ), patrón que coincide con lo observado para otras especies quienes dejan desatendida la nidada al amanecer y al anochecer (C. noctitherus, Vilella 1995; Phalaenoptilus nuttallii, Woods et al 2005;A. sericocaudatus, Wilkinson 2009;A.…”

“…No obstante, no está probado que los machos puedan proveer calor a los huevos (O'Connor & Ritchison 2013). En la mayoría de las especies de caprimúlgidos el cuidado y alimentación de pichones sería una tarea compartida entre ambos sexos (ej., Cink 2002, Woods et al 2005, Latta & Baltz 2012, O'Connor & Ritchison 2013, Salvador & Bodrati 2013.…”

Breeding biology and parental care behaviors of two nightjar species of Córdoba, Argentina. – Nightjars are insectivorous birds whose mimetic coloration and night activity make them difficult to study. The aim of this study has been to describe aspects of the little-known breeding biology of Little Nightjar (Setopagis parvulus parvulus) and Band-winged Nightjar (Systellura longirostris patagonicus), two sympatric species in the Chaco Serrano formation of the province of Córdoba, Argentina. We observed great similarity in the nest and nesting site of the studied species, as well as in reproductive traits and parental care behaviors. Clutch size of both species was two eggs, and incubation (monitored with temperature sensors and direct observations) was provided mostly by females, whereas males shared the duties a few hours during the day. The incubation period lasted approximately 17 days, and percentage of nest attentiveness was high in both species (Little Nightjar incubated 92.81 ± 2.33% and Band-winged Nightjar incubated 92.39 ± 4.73% per day). No translocation of eggs was documented in any nest, but we observed movements of chicks away from the nest, at distances that increased progressively as the young aged. In both species, growth curves of chicks indicated a size difference between the chicks of the same nest, possibly associated to asynchronous hatching. This study contributes to the knowledge of life history strategies and reproductive behavior of Neotropical nightjars, which so far is limited and deserves future attention.
