“…The clutch size found here also followed the family and species pattern (Matamala et al, 2020). Petry and Fonseca (2005) registered similar variations between one and four eggs, as well as Almeida et al (2012), with nests with two to three eggs.…”

“…Phimosus infuscatus also started breeding in August for two seasons in Rio Grande do Sul (Petry & Hoffmann, 2002;Petry & Fonseca, 2005). However, in the observations of Piacentini et al (2009) and in the season studied by Grose et al (2012), both in Santa Catarina, breeding occurred later, between September and December and October and February, respectively, close to what Matamala et al (2020) reported in the Brazilian southeast. In Mato Grosso, nests were reported before October (Almeida et al, 2012).…”

“…However, resource supplies, floods, and predation are best known for influencing reproduction (Fasola, 1998;Kushlan & Hancock, 2005;Kelly et al, 2008). In Venezuela, more than 80% of eggs and juveniles were lost to predation in one season (Matamala et al, 2020), which was also recorded by Almeida et al (2012) in Mato Grosso. Even though we didn't witness acts of predation in this study, S. merianae and F. catus are known to affect bird populations in urban areas (Kiefer & Sazima, 2002;Baker, Bentley, Ansell, & Harris, 2005), and were the potential predators seen the closest to nests.…”

“…The Bare-Faced Ibis Phimosus infuscatus (Lichtenstein, 1823) is a gregarious aquatic bird with three recognized subspecies: P. i. berlepschi Helmayr 1903, found in Colombia, Ecuador, Brazil (northwest), Venezuela, the Guianas, and Surinam; P. i. infuscatus (Lichtenstein, 1823), in Bolivia, Paraguay, Argentina, and Uruguay;and P. i. nudifrons (Spix, 1825), in Brazil, south of Amazon (Sick, 1997;Matamala et al, 2020).…”

“…The species inhabits open areas, wet meadows, pastures, savannas, marshes, rice fields, and margins of lagoons, swamps, and streams that are usually humid or flooded, where it feeds on small invertebrates and vegetable matter by probing part of its bill in the soil (Sick, 1997;Matamala et al, 2020).…”

The Bare-faced Ibis is a gregarious bird found in South America. In the face of a rapid expansion in a southern state in Brazil and a lack of detailed information about the species' reproduction, two breeding areas were studied weekly for two consecutive seasons. We registered numbers and characteristics of adults, nests, eggs, and chicks, calculated success estimates, and assessed nest installation preferences. Chick morphology, age, and measurements served to define five growth stages. The species used the margins of two close rivers in Santa Catarina to build nests, lay eggs, and develop parental care between August and January, with success estimates as expected for the family. We observed a preference for the eastern margin of the rivers and proximity to bridges for nest installation, where the muddy margin provides resources for juvenile feeding. Two colony models were defined based on the near or far installation of the nests. Variations in egg and chick dimensions indicated higher adult investment in the second season, with negative allometric growth of the bill and tarsus of chicks related to weight. The results presented suggest favorable conditions for the species’ reproduction in the region, a considerable factor in understanding its expansion in recent years.
