“…As for many threatened island species, limited biological data were previously available for the Cocos buff-banded rail (Gibson-Hill 1949, 1950Marchant and Higgins 1993;Taylor 1998;Reid 2000;Woinarski 2014). However, as demonstrated here, camera traps can provide much behavioural information about rail species (Znidersic 2017;Colyn et al 2017), with minimal disturbance over an extended period. In this study, camera traps were effective in collecting previously undescribed behavioural data, confirming persistence of the founder population and confirming presence of house mice within rail breeding sites.…”

Island endemic species are disproportionately represented in the tally of global extinctions. The island endemic Cocos buff-banded rail (Hypotaenidia philippensis andrewsi) is classified under the Australian Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) as Endangered. It is restricted to the remote Cocos (Keeling) Islands in the Indian Ocean where, until 2013, only the island Pulu Keeling supported a population of this species, following earlier extirpations of the bird from islands in the southern atoll. To establish a second viable population to mitigate against potential extinction of this subspecies, 39 rails were reintroduced from Pulu Keeling to Horsburgh Island in April 2013. As a component of post-translocation monitoring, we conducted intensive camera trapping from 29 May 2015 to 30 June 2016 (397 calendar days) to investigate recruitment success, behaviour and potential threats to the population. Biannual transect sampling to monitor and investigate long-term population density was also conducted. We found Cocos buff-banded rail persisting on Horsburgh Island with an increase in the founder population to 97 rails in February 2016. Ongoing recruitment with breeding activity on Horsburgh Island and the emigration of rails to nearby (2.5km) Direction Island is indicative of short-term success. Images from the camera traps have documented behaviours that have not previously been described for the species. House mice were also identified as a potential threat to the Horsburgh Island rail population. Island rail species have suffered a high rate of extinctions, and their conservation remains a formidable challenge, given the risks of continuing introductions of invasive mammalian predator species.

“…Las aves pueden ser clasificadas según el lugar en el cual buscan su alimento en los siguientes gremios: aéreas, arborícolas, acuáticas y terrestres (De La Peña & Krüger, 1987). Las cámaras trampas han sido utilizadas mayormente para el estudio de aves terrestres y acuáticas, de tamaño grande, especialmente pertenecientes a los órdenes Galliformes, Gruiformes y Tinamiformes (Li, Mcshea, Wang, Shao, & Shi, 2010;Armenteros, Prieto, Lomillos, Alonso, & Gaudioso, 2015;Mena, Zúñiga Hartley, Villacorta Pezo, & Salazar Zorrilla, 2016;Colyn, Campbell, & Smit-Robinson, 2017).…”

Con el objetivo de evaluar la utilidad del fototrampeo para el estudio de la avifauna, se analizaron los registros obtenidos, entre julio del 2015 y julio del 2016, por cámaras trampa instaladas en 12 puntos con aguadas artificiales de la Estancia Montania, Departamento de Boquerón, Paraguay. Se determinó la riqueza, composición y tasa de captura registrada en bosques xerófiticos y pasturas exóticas. Se comparó la riqueza y composición de aves detectada mediante cámaras trampa con la obtenida a través métodos auditivos y visuales. Mediante fototrampeo, fueron registradas 74 especies, pertenecientes a 30 familias y 16 órdenes. El bosque xerofítico y la pastura exótica poseen un 52,7% de similitud en cuanto a la composición de las especies. Las especies registradas con mayor frecuencia fueron Leptotila verreauxi (16,14%), Ortalis canicollis (14,28%) y Furnarius cristatus (11,39%). Las cámaras trampa resultaron efectivas para el registro del 33% de las especies identificadas en el área con base en técnicas de muestreo de observación directa y auditiva, y adicionaron dos especies no detectadas por métodos directos. Por ello, resulta apropiado para complementar métodos basados en la observación directa, particularmente para el registro de especies cinegéticas del ecosistema chaqueño pertenecientes a los órdenes Tinamiformes y Columbiformes.

“…All continuous covariate data were standardised using the z-transformation equation (MacKenzie 2012). Covariate data collected and/or collated per camera trap site included average vegetation height, basal cover, canopy cover, dominant fine-scale vegetation community, water depth, trail presence/absence, trail width and trail type (Colyn et al 2017). Model fit was assessed and ranked using the Akaike Information Criterion (AIC) model selection criteria, which included AIC, delta AIC, AIC weight and Model Likelihood values (Anderson and Burnham 2002).…”

SummaryThe ‘Critically Endangered’ White-winged Flufftail Sarothrura ayresi is regarded as one of the rarest and most threatened rallids in Africa. Due to the species’ low density, habitat preference, cryptic colouration, elusive behaviour and lack of auditory cues has resulted in it being one of the most challenging species to survey using traditional methods such as auditory surveys and rope dragging. Numerous data deficiencies exist regarding facets of the species’ ecology, distribution, habitat-use and population status. A stratified array of nine camera localities was used within high-altitude palustrine wetland habitat to ascertain if this non-invasive technique could successfully document the first estimate of site occupancy, fine scale habitat use and activity patterns of this very rare species. Our study accumulated a total of 626 camera days and eight independent sightings of White-winged Flufftail across the respective austral summer season. Furthermore, our study confirms the applicability of camera trapping to other rare and elusive rallid species. Our results confirm that White-winged Flufftail is a low-density habitat specialist species, with site occupancy influenced positively by basal and canopy vegetation cover and detection probability influenced negatively by water depth within associated wetland habitats. Activity pattern analyses displayed that peak activity occurred at dawn and dusk, which yielded the highest degree of activity overlap with the only other migratory rallid recorded, Spotted Crake Porzana prozana. Our study also recorded the first apparent territorial display behaviour noted for the species. Our study supports the need for conservation initiatives focused on securing contiguous sections of suitable wetland habitat in order to accommodate the persistence of this globally threatened species.
