“…The breeding activities aligned with the rainy season in the study site. This species had a longer breeding season (6 to 7 months) than some Neotropical species from the Atlantic Forest (Aguilar et al 2000, Duca and Marini 2004, Hoffmann and Rodrigues 2011. The breeding season of the Tropical Mockingbird was shorter than the breeding season of the subspecies M. gilvus malnopterus in Venezuela (Paredes et al 2001).…”

This study describes aspects of the life history of the Tropical Mockingbird Mimusgilvus (Vieillot, 1808), including the breeding period, clutch size, nestlings and a list of plants used for nesting. Nests were monitored in an area of Restinga (sand-coastal plain) habitat in a protected area in southeastern Brazil. The data from 181 nests during five breeding seasons (2010-2014) showed that the Tropical Mockingbird has a long breeding season (26.1 ± 2.6 weeks) with up to two peaks of active nests from August to March. The breeding pairs made up to four nesting attempts in the same breeding season. The mean (± SD) clutch size was 2.4 ± 0.6 eggs (n = 169). The mean (± SD) incubation period was 14 ± 0.6 days, and the nestling remained in the nest for 14.5 ± 2.2 days. The nests were built on thirty plant species, and Protiumicicariba (DC.) Marchand. was the plant species most commonly used for nesting. The breeding parameters of the Tropical Mockingbird are similar to those of other Mimidae species. The knowledge gained from this study makes the Tropical Mockingbird a good choice for future studies, particularly for testing ecological and evolutionary hypotheses regarding life history attributes, habitat selection and parental investment.

RESUMEN ∙ El Doradito Común (Pseudocolopteryx flaviventris), es una especie que nidifica en juncales y pastizales inundados o cercanos a cuerpos de agua en el centro y este de Argentina. Es considerado residente en gran parte de su rango de distribución pero migrante en su distribución Norte y Sur, aunque sus movimientos estacionales han sido poco estudiados. El objetivo de este estudio fue investigar la biología reproductiva y el estatus de ocurrencia del Doradito Común en la Reserva de Biosfera Parque Atlántico Mar Chiquita (37°40’S, 57°23’O; Argentina) en el límite sur de su distribución. El Doradito Común estuvo presente en el área desde octubre hasta marzo. Durante dos temporadas reproductivas (2012–2013, 2013–2014) encontramos 35 nidos de la especie en pastizales de Cortaderia selloana. El tamaño de puesta media fue de 2,5 ± 0,7 (DE) huevos (n = 25) y el período medio de incubación 17,2 ± 2,5 días (n = 6). Los pichones permanecieron en el nido por 13,2 ± 1,7 días (n = 5). La tasa de supervivencia diaria de los nidos fue de 0,948 ± 0,013 (n = 22) para 2012–2013 y 0,983 ± 0,082 (n = 13) para 2013–2014. La probabilidad de supervivencia del total del ciclo reproductivo (media = 30 días) fue de 20% para 2012–2013 y de 60% para 2013–2014. La depredación fue la principal causa de pérdida de nidos (92% de las pérdidas), siendo mayor durante el período de incubación (69%). El Doradito Común presenta movimientos migratorios al sur de su rango de distribución, tiene un éxito reproductivo variable entre años siendo la depredación la principal causa de fallo reproductivo.ABSTRACT ∙ Breeding biology and migratory status of the Warbling Doradito (Pseudocolopteryx flaviventris) nesting in grasslands in its southernmost distribution The Warbling Doradito (Pseudocolopteryx flaviventris) nests in reedbeds and flooded grasslands near water bodies in central and eastern Argentina. This species is considered resident in large part of its range and migrant in the North and South of its range, but its movements remain poorly understood. We studied the breeding biology and migratory status of the Warbling Doradito in the Biosphere Reserve Parque Atlántico Mar Chiquita (37°40’S, 57°23’W; Argentina), at the southernmost limit of its distribution. Warbling Doraditos arrived at the breeding area in October and remained until March. During two breeding seasons (2012–2013, 2013–2014) we studied 35 nests of the Warbling Doradito in Cortaderia selloana grasslands. Mean (± SD) clutch size was 2.5 ± 0.7 eggs (n = 25) and mean incubation period was 17.2 ± 2.5 days (n = 6). Chicks remained on average 13.2 ± 1.7 days in the nest (n = 5). The daily survival rate of nests was 0.948 ± 0.013 (n = 22) for the 2012–2013 breeding season and 0.983 ± 0.082 (n = 13) for 2013–2014. The probability of nest survival to fledging (mean = 30 days) was 20% for 2012–2013 and 60% for 2013–2014. The main cause of nest failure was predation (92% of failed nests). Nest predation was higher during the incubation period (69%) than during the nestling period (31%). Therefore, the Warbling Doradito has migratory movements in the south of its range, has variable reproductive success between years, and the main cause of nest failure was predation.

“…New molecular data suggest cryptic species within the genus, which prompts calls for more extensive molecular phylogenetic analysis of the group (105). Populations of Philornis have been found in the United States (104), the Caribbean (34,118), Mexico (54,123), Costa Rica, (120), Panama (9), Peru (101,114), Brazil (57,85,102), Argentina (10, 21, 28, 89,92,94,106,111), Venezuela (116), and mainland Ecuador (13). Specimens are rare in collections (25) and generally reared from pupae and larvae collected from birds' nests.…”

Alien Invasion: Biology of Philornis Flies Highlighting Philornis downsi, an Introduced Parasite of Galápagos Birds

The muscid genus Philornis comprises approximately 50 described species of flies, nearly all of which are obligate parasites of nestling birds. Philornis species are native to the Neotropics and widely distributed from Florida to Argentina. Most research on this group has focused on P. downsi, which was introduced to the Galápagos Islands in the late twentieth century. Although Philornis parasitism kills nestlings in several native host species, nowhere do the effects seem more severe than in P. downsi in the Galápagos. Here, we review studies of native and introduced Philornis in an attempt to identify factors that may influence virulence and consider implications for the conservation of hosts in the Galápagos.
