“…Nests were found by following adults carrying material for nest construction, or delivering food to the nestlings (Martin and Geupel 1993), and monitored every 1-3 days since located. Nest type and egg shape were named following Winkler (2004), and they were measured with a caliper to the nearest 0.1 mm. Eggs were weighed to the nearest 0.1g with a spring scale.…”

“…The incubation period was considered from the first day of incubation to the day before hatching, and nestling period from the day of hatching to the day before fledging (Winkler 2004, Oliveira et al 2010. As neither eggs nor nestlings were marked, we assumed that the first eggs to be laid were the first to hatch, and that the first young to hatch were the first to fledge (Davanço et al 2013).…”

ABSTRACT. Despite the fact that E. chlorotica (Linnaeus, 1766) is common and widely distributed in South America, the reproductive aspects of the species are poorly documented. Here we present data on 18 active nests found from August to February, between 2007 and 2012. Nests were globular with a lateral entrance, and measured 97.9 ± 14.4 mm in outside height, 110.6 ± 11.6 mm in outside diameter, and were 4.88 ± 2.09 m above ground. They were often supported from bellow and were composed mainly of tiny dry leafs and leaflets, fine petioles, and plumed seeds, all compacted with spider web silk. Eggs were laid on consecutive days or with one day interval, and clutch size varied from 1-3 eggs (2.1 ± 0.6, n = 9 nests). Only females incubated the eggs, but both sexes were involved in nest construction and nestling attendance at similar rates. Incubation and nestling periods were 14 and 21 days, respectively, and overall nest survival probability was 5%. A vespiary used for nesting was not occupied by wasps and nest material was deposited only to form the incubatory chamber. Although nesting near wasps or bees is a widespread strategy among birds in general, nesting inside the nests of social insects is a poorly documented behavior.

“…Moura, personal observation). Among the reproductive characteristics of the species are: average clutch size of two, incubation by females only, 24 days of incubation and nestling periods, and feeding of ofspring by both parents (Zima and Francisco 2016). Grey Pileated Finch individuals are more transient where seeds are more common than arthropods in their diet (Poulin et al 1994a).…”

Rainfall and population dynamics of Grey Pileated Finch Coryphospingus pileatus (Aves: Passeriformes) in a Neotropical dry forest

In tropical dry environments rainfall periodicity may afect demographic parameters, resulting in luctuations in bird abundance. We used capture-recapture data for the Grey Pileated Finch from a Neotropical dry forest to evaluate the hypothesis that intra-and inter-annual survival, individuals entrance and population abundance, are related to local rainfall. Sampling occurred across 3 years, with individuals captured, tagged and evaluated for age and presence of brood patch every 14 days. Using the POPAN formulation, we generated demographic models to evaluate study population temporal dynamics. Best-it models indicated a low apparent annual survival in the irst year (16%) compared to other years (between 47 and 62%), with this low value associated with an extreme drought. The abundance of juveniles at each capture occasion was signiicantly dependent on the accumulated precipitation in the previous 14 days, and the juvenile covariate was a strong predictor of the intra-annual entrance probability (natality). Individuals entrance during the reproductive period corresponded to 53, 52 and 75% of total ingress for each year, respectively. The trend in sampled population size indicated positive exponential growth (N initial = 50, N last = 600), with intra-annual luctuations becoming progressively more intense. Low survival was relevant during population decline at study onset, while at study end intense Individuals entrance promoted rapid population growth. Thus, the indirect efects of rainfall and the combined efect of two demographic rates operated synergistically on the immediate population abundance of Grey Pileated Finch, an abundant bird in a Neotropical dry forest.

The genus Thraupis (Thraupidae, subfamily Thraupinae) is composed of seven species of small Neotropical passerines that represent the typical tanagers (Burns et al. 2016). They are characterized by discrete plumages, predominantly bluish and olive, and absence of sexual dimorphism in most species (Ridgely & Tudor 1989). They inhabit humid forests or wooded areas, various types of open areas, and even urban environments (Ridgely & Tudor 1989, Hilty 2019). Despite the commonness of some taxa, reproductive aspects are generally poorly documented, although nests and eggs have been welldescribed except for the Azure-shouldered Tanager, Thraupis cyanoptera, the Golden-chevroned Tanager, Thraupis ornata, and the Glaucous Tanager, Thraupis glaucocolpa (Hilty 2019). The Azure-shouldered Tanager is endemic to the Atlantic Forest of southeastern Brazil, and can be found from the slopes of Serra do Mar to humid montane forests from southeast Bahia, Minas Gerais and Espírito Santo states, southern to Rio Grande do Sul (Ridgely & Tudor 1989, Hilty 2019). It is more forest-dwelling than some congeners, occurring in forest canopy, but also in borders and secondary growth (Ridgely & Tudor 1989, Naka et al. 2002). The only information on the reproductive biology of this species is the description of two eggs as being pale blue with a few round spots of very dark purple color (Ogilvie-Grant 1912), and a mention by Kirwan (2009) that "a nest was being built on a bromeliad epiphyte in a
