“…This result supports the idea that urbanization homogenizes the composition of bird communities by the replacement of native species by cosmopolitan species (McKinney 2006, Filloy et al 2015. The native Eared Dove was more abundant in moderate levels of urbanization, and it appears to be the main suburban adapter in the three cities of this study and other Neotropical cities (Fontoura 2013, Fontoura & Orsi 2014.…”

∙ Urbanization is expanding continuously over rural and natural areas and it is imperative to analyze its effect on bird communities. Although the impact of urbanization on bird communities in the Neotropical region has been explored by several authors, there is a scarcity of comparative studies with standardized methodologies that allow establishing whether the effects of urbanization are similar in different ecoregions. We analyzed the urbanization impact on bird communities in three Neotropical cities. Cities were located in different biomes: La Paz (Bolivia) surrounded by a highland plateau and inter‐Andean valleys; Mar del Plata (Argentina) surrounded by agroecosystems of the pampas; and Osorno (Chile), surrounded by agroecosystems, timber plantations, and remnants of temperate forests. In general, high levels of urbanization correlated negatively with bird richness in the three cities, but the response of bird richness to urbanization varied among cities, being linearly negative in La Paz and Osorno and declining only towards high levels of urbanization in Mar del Plata. The effect of urbanization was stronger in La Paz, where more bird species were absent toward higher urbanization levels. Bird abundance did not show significant responses to urbanization. Exotic bird abundance showed a positive relationship with urbanization in the three cities. Bird composition differed between cities and urbanization levels. The House Sparrow (Passer domesticus) was the most abundant species in more urbanized sites, the Eared Dove (Zenaida auriculata) in moderate levels of urbanization, whereas the Rufous‐collared Sparrow (Zonotrichia capensis) was most abundant in the less urbanized sites. The results of our study showed that the impact of urbanization on bird communities in the Neotropical region varied among cities, probably as a result of latitude and the structure of rural areas.Resumen ∙ Comunidades de aves en gradientes de urbanización: un análisis comparativo entre tres ciudades Neotropicales La urbanización se está expandiendo continuamente en áreas rurales y naturales, y siendo imprescindible analizar su efecto sobre las comunidades de aves. Aunque el impacto de la urbanización en el Neotrópico ha sido estudiado por varios autores, existe una escasez de estudios comparativos entre diferentes ecorregiones mediante el uso de metodologías estandarizadas. Por lo tanto, analizamos el impacto de la urbanización sobre comunidades de aves en tres ciudades Neotropicales. Las ciudades estuvieron localizadas en diferentes biomas: La Paz (Bolivia) rodeada por un altiplano y valles interandinos; Mar del Plata (Argentina) rodeada por agroecosistemas de las Pampas; y Osorno (Chile), rodeada por agroecosistemas, plantaciones de árboles y remanentes de bosques nativos. En general, altos niveles de urbanización se correlacionaron negativamente con la riqueza de aves en las tres ciudades. Sin embargo, la respuesta de la riqueza de aves a la urbanización varió entre ciudades, siendo negativamente lineal en La Paz y Osorno, para disminuir solo a partir de altos niveles de urbanización en Mar del Plata. El impacto sobre la riqueza fue mayor en La Paz, donde más especies de aves se perdieron hacia los niveles más altos de urbanización. Por otro lado, la abundancia de aves no se correlacionó con la urbanización. La abundancia de especies exóticas mostró una relación positiva con la urbanización en las tres ciudades. La composición de aves cambió entre niveles de urbanización; el Gorrión común (Passer domesticus) fue la especie más abundante en los niveles más altos de urbanización, la Torcaza (Zenaida auriculata) en sitios de urbanización moderada, mientras que el Chingolo (Zonotrichia capensis) fue la especie más abundante en los niveles más bajos de urbanización. Los resultados de nuestro estudio mostraron que el impacto de la urbanización sobre las comunidades de aves en la región Neotropical varió entre ciudades, probablemente como resultado de la latitud y la estructura de las áreas rurales.

“…Habitat requirements, such as foraging stratum and feeding and nesting sites, may explain the negative effects of tree richness and canopy cover on the abundance of House Wren, Blue-black Grassquit, Eared Dove, and Ruddy Ground-Dove. The last two are synanthropic seed-eating species that forage on the ground in open spaces (Fontoura and Orsi 2014), and have large populations in urban landscapes in Brazil. These species have behavioral plasticity and can tolerate human-made habitats, such as using urban structures as support for their nests (Guaraldo et al 2015).…”

Vegetation structure drives taxonomic diversity and functional traits of birds in urban private native forest fragments

Many studies in urban landscapes have revealed that vegetation structure influences the taxonomic diversity and traits of birds and drives greater bird richness in greenspaces. However, most of these studies have been carried out mainly in public spaces. Private lands represent large components of cityscapes worldwide, and so understanding the role they play in the maintenance of biodiversity, and how vegetation traits drive the ecological attributes of birds, remain poorly known. Here we identified local factors of vegetation related to the bird fauna of urban private native forest fragments in Sorocaba, state of São Paulo, Brazil, with a focus on their ecological attributes. We predicted that increased vegetation structure would select birds that depend on forest environments and the resources they support. We sampled 13 vegetation traits in 28 private urban native forests to evaluate the relationship between vegetation structure and taxonomic diversity and functional traits of birds. Confirming our prediction, vegetation structure shaped the ecological attributes of birds, with five vegetation traits driving bird taxonomic diversity and functional traits, of which the number of standing dead trees was related to more bird ecological attributes. Vegetation structure in urban private native forest fragments may increase habitats and resources, thus supporting habitat-and feeding-specialist species. Our results provide insights for public policies aimed at management and maintaining vegetation structures that benefit bird fauna (e.g. number of standing dead trees, tree richness, canopy cover), in support of the ecological functions they perform in urban landscapes.

“…The species is preferentially granivorous, has low sensitivity to environmental disturbances, lives in fields and open formations, and its presence has been strongly associated with damage to crops (Silva and Guadagnin 2018). It is also found in several Brazilian urban centers (Fontoura and Orsi 2014).…”

Territorial expansion of Zenaida auriculata (Aves: Columbidae) in the Brazilian Amazon

Birds are considered bioindicators of environmental quality because they are sensitive to environmental changes. The eared dove (Zenaida auriculata) is associated with open areas, has low sensitivity to environmental changes and is widely distributed in Brazil, although it is not typically found in the Amazon region. We analyzed the biogeographic expansion of this species in the Brazilian Amazon through searches carried out on digital citizen science platforms. The records of Z. auriculata were related with the area of accumulated deforestation in the biome. We identified 804 records of Z. auriculata in the Brazilian Amazon, of which 259 were in areas where its occurrence had been previously unknown. We show that the species has been expanding its geographic distribution, clearly overlapping with deforested areas.
