“…Our CT study provides new information on the breeding phenology of BFC, suggesting year-round breeding in the northern Pantanal. It also extends the information on the BFC life history provided by Desbiez & Bernardo (2011), Fernández-Duque et al (2013, Gomes et al (2018), Laino et al (2018), andZalazar et al (2018). In addition, our results show that long-term studies, especially those using CTs, are crucial to better understand the biology and behavior of BFC and other cracids.…”

“…Reports of offspring CT captures of BFC or other curassow species captured during long-term studies are rare. No offspring have been reported for BFC, even when great efforts were made for CT data collection and adult (paired) individuals were frequently captured (Fernández-Duque et al, 2013;Gomes et al, 2018;Laino et al, 2018;Zalazar et al, 2018). This is also true for reports of other cracids.…”

“…All CTs were operated using a passive infrared-triggered system, and captures were recorded with date and time. CT studies on the life history of BFC (Fernández-Duque et al, 2013;Gomes et al, 2018;Laino et al, 2018) and other Crax species (Srbek-Araujo et al, 2012;Lafleur et al, 2014;Alves et al, 2017;Pardo et al, 2017;Pérez-Irineo & Santos-Moreno, 2017;Whitworth et al, 2018) have documented the scientific importance of using this method and have provided a large amount of new data on various aspects of cracid behavior, occurrence, and habitat preferences.…”

“…In Brazil, BFC is widely distributed and has been reported in Pará, Minas Gerais, Goiás, Mato Grosso, and northern Mato Grosso do Sul (BirdLife International, 2021). It is considered rare in São Paulo state (Gomes et al, 2018) and in Paraná, while it is still common in the northern Pantanal (Mato Grosso), Emas (Brasilia), and Araguaia National Parks (Del Hoyo et al, 2019), presumably because habitat destruction and hunting pressure are lower in these areas. Despite its relatively large range of occurrence (4,720,000 km²), its global conservation status is classified as "vulnerable" and was recently classified as a "high conservation priority" species (Brooks & Strahl, 2000;Birdlife International, 2021).…”

Knowledge of the reproductive biology of Bare-faced Curassows (BFC) from their natural habitats is very limited. Our study covers a two-and-a-half year breeding phenology on BFC in the northern Pantanal (Mato Grosso State, Brazil) with the main objective of collecting information on reproduction biology to contribute to future conservation management strategies of this cracid, which received a recent status of "High Conservation Priority". The study was conducted at the SESC Pantanal, Baía das Pedras, Mato Grosso, Brazil (16°29′55″S, 56°24′46″W), a private protected area of approximately 4,200 ha. Between July 2015 and December 2017, 37 sampling locations were monitored with camera traps placed in a regular grid with a spacing of 1 km. Offspring were detected at least once at 8 locations, namely, in March, April, and May 2016 and in June, July, October, and November 2017, always together with parent(s). Territorial overlap between different family groups was detected. The camera trap dataset was supplemented by data from Citizen Science Projects (i.e., eBird) and the Global Biodiversity Information Facility (GBIF). Based on feather developmental stages and body size, offspring were classified into different age classes. Age determination indicates that breeding occurs year-round in the northern Pantanal region, supported by eBird and GBIF data. The use of a grid-based design for future camera-trapping studies of BFCs is strongly recommended. Our study is of biological relevance for conservation management projects since data were collected in an area with low anthropogenic disturbance and intact ecosystem services.

“…According to the Institute Union for Conservation of Nature, this species is considered vulnerable to the risk of extinction [ 22 ]. One of the main causes that endanger the existence of this species is hunting, mainly observed in areas without environmental protection [ 23 ]. In Brazil, a health assessment of different Cracidae species, including C. fasciolata (n = 28) has demonstrated exposure to chicken pathogens [ 24 ].…”

Background Osteosarcoma is a malignant mesenchymal bone tumor. Although it is a common tumor in the appendicular skeleton of dogs and cats, it is rarely reported in birds. Retroviruses are usually associated with solid tumor development in different avian species. Case presentation: This report aims to describe a case of osteosarcoma associated with the avian leukosis virus in a captive bare-faced curassow (Crax fasciolata). A captive adult female bare-faced curassow presented with lameness, hyporexia, and a non-ulcerative and firm tumor in the right femur. The bird was euthanized due to the poor prognosis. Histopathology revealed an infiltrative mesenchymal neoplasm consisting of spindle cells with moderate cell pleomorphism, organized in bundles and interspersed by marked deposition of the osteoid matrix, which was compatible with osteosarcoma affecting both femur and tibiotarsus, with renal metastasis. Immunohistochemistry of the primary and metastatic tumor demonstrated vimentin expression by neoplastic cells. Samples of the neoplasm, bone marrow, and spleen were processed for PCR, which enabled the demonstration of proviral avian leukosis virus (ALV) DNA. Conclusions To the best of our knowledge, this is the first report of an osteosarcoma in a bare-faced curassow with an unusual polyostotic manifestation and associated with ALV infection.

Among Neotropical cracids (Galliformes), many taxa are declining rapidly in population size and facing local extinction. However, in the Brazilian Pantanal, several species occur sympatrically and in abundant numbers to allow for long-term studies. Therefore, the study was intended to collect data and statistically evaluate the life history patterns of Bare-faced Curassow (Crax fasciolata), a high-conservation-priority species. Additionally, the effect of applying commonly used independence filters on camera trap data was evaluated. The study was conducted in the SESC Pantanal, Baía das Pedras, Mato Grosso, Brazil, a private protected area of approximately 4200 ha. Between July 2015 and December 2017 (4768 sampling days), 37 sampling locations were monitored with camera traps placed in a regular grid with a spacing of 1 km. Crax fasciolata was detected at 26 (70.27%) of them, with 357 independent captures (554 individuals). Capture success differed among the four seasonal periods, being highest during the receding and lowest during the high-water period. The seasonal difference was more pronounced in the savanna, with significantly lower activity during the rising period and higher activity during the receding period, while it was more uniform in forest-dominated areas. Groups with offspring were more active during the period of receding water, indicating the peak of reproductive activity in the months before. The daily activity of the species followed a bimodal pattern, with peaks between 06:00 and 07:00 and 16:00 and 17:00. Daily activity rhythms were similar when compared between seasonal periods, sexes, and adults with or without offspring and differed between two habitats (more homogeneous in the forest). The mean detected group size was 1.55 ± 0.81 SD, with four animals exhibiting the largest observed aggregation. Larger unisexual aggregations of adults were not observed. The offspring sex ratio was significantly female-skewed at 0.51:1.00, while the adult sex ratio was considered equal at 1.05:1.00 (male:female). The use of different independence filters did not alter the BFC general activity pattern estimates. Cracids can be considered important bioindicators of habitat quality. The results of this study outline the importance of the Pantanal as a stronghold for this species and the privately protected areas with low anthropogenic activity as highly beneficial to its populations.
