Elapomorphus quinquelineatus (Raddi, 1820) is a fossorial snake endemic to the Atlantic Rainforest of southeastern to southern Brazil (Nogueira et al. 2019). It has cathemeral habits and is found even in disturbed habitats (Costa et al. 2010). Elapomorphus quinquelineatus is commonly found moving above the ground, although it also has fossorial habits (Hartmann et al. 2009; Costa et al. 2010), relying on crypsis to avoid predation (Martins et al. 2008), and may use cloacal discharge and erratic movements if handled (Marques et al. 2019). This rear-fanged snake is not known to bite as a defense, although having a highly hemorrhagic venom (Salomão et al. 2003). In this study, we report a specimen of E. quinquelineatus preyed by a Micrastur semitorquatus (Vieillot, 1817) (Falconidae), popularly known as Collared Forest-Falcon, and reviewed records of predation on the species. Between 8 and 9 a.m. on 10 November 2020, one of us (LL) was driving on a dirt road in Reserva Particular do Patrimônio Natural Chapadão da Serra Negra (21.9634°S, 43.8014°W), a private protected area of Atlantic Forest in Santa Bárbara do Monte Verde, Minas Gerais, southeastern Brazil. LL saw a Collared Forest-Falcon (M. semitorquatus),

“…history. The same is true for E. quinquelineatus, which has a narrower range and a mostly fossorial lifestyle.Prey-predator reports like this are essential to fill basic gaps in our knowledge of biodiversity, which can later become the basis for wider studies (e.g.,Schalk & Cove, 2018;Souza et al 2022). …”

“…In Brazil, scientific publications based on citizen-collected data mostly focus on birds (Schubert et al 2019, Alexandrino et al 2022, de Souza et al 2022 (Cunha et al 2017), nevertheless, there are many ongoing national initiatives that are producing interesting results. Some of these local or national monitoring programs deserve to be highlighted, such as Wikiaves (for birds -https://www.wikiaves.com.…”

Based on debilitating recent budget cuts for science, Brazilian researchers had to find alternative ways to continue scientific production. Here we provide a perspective for the use of citizen-science data deposited in the iNaturalist platform as an alternative source of data to support biodiversity research. Observations contributed by volunteers can be analyzed at large spatial and temporal scales and can respond to questions in behavioral and population ecology. We analyzed this potential through the example of Brazilian amphibians, a group that is less studied worldwide than birds. In fact, to our knowledge, only two studies have been published that are based on citizen-science data for Brazilian amphibians. At the time of writing, the iNaturalist platform has over 14,800 research grade observations from Brazil, representing 698 species, a number increasing daily. Compared to other species-rich countries, volunteer-collected datasets from Brazil cover a relatively high taxonomic diversity (61%), providing a plethora of valuable data. Despite this potential, there are large spatial gaps in sampling in Brazil.Here we encourage established and budding herpetologists not only to use the platform to retrieve data, but also to contribute to iNaturalist actively, with new observations, as well as by identifying species in existing records.

“…Thus, their role in animal predation needs to be better examined. We supposed that this scarcity of quantitative information on the diet of toucans could be mitigated through the use of community science data, as recently occurred for bird species of other families found in Brazil (e.g., Crozariol & Gomes 2010, Teixeira et al 2019, Tubelis & Sazima 2021, Tubelis & Wachlevski 2021, de Souza et al 2022, Gomes & Tubelis 2022, Costa & Tubelis 2023.…”

La familia Ramphastidae (Piciformes) es endémica al Neotrópico e incluye 36 especies. Aunque son consideradas principalmente aves frugívoras, también se alimentan de invertebrados y pequeños vertebrados. El objetivo de este estudio fue examinar el consumo de recursos aviares por parte del Tucán toco (Ramphastos toco), el Ramphastidae más común en el Brasil no amazónico. En abril de 2022 se realizó una búsqueda de registros fotográficos de esta especie en WikiAves, la mayor base de datos de ciencia ciudadana sobre aves brasileñas. Un total de 271 fotografías tenían evidencia de actividades de alimentación. La mayoría involucraba recursos no aviares (85%), como frutas, mientras que una porción menor se refería a recursos aviares (15%). Estos 42 registros que involucran recursos aviares fueron más numerosos en octubre-diciembre que, en otros períodos del año, demostrando el consumo de huevos (50%), polluelos (45%) y aves juveniles o adultas (5%). Estos registros de alimentación incluyeron especies de las familias Tyrannidae, Columbidae e Icteridae, teniendo al Bichofué (Pitangus sulphuratus) como la especie de presa más común. Por otro lado, los registros que involucraban recursos no aviares ocurrieron a lo largo del año. Como resultado, la proporción de fotografías con recursos aviares fue mayor en octubre-diciembre que en otros períodos. Esta frecuencia relativamente alta de recursos aviares en la dieta del tucán toco coincide con su período de anidación en Brasil. Con nuestro estudio reconfirmamos la utilidad de la ciencia participativa para mejorar nuestro conocimiento sobre la dieta y la ecología alimentaria de las aves neotropicales.
