β-diversity has been under continuous debate, with a current need to better understand the way in which a new wave of measures work. We assessed the results of 12 incidence-based β-diversity indices. Our results of gradual species composition overlap between paired assemblages considering progressive differences in species richness show that: (i) f...

In this study we focused on urban bird diversity across Mexico, a megadiverse country, with a special focus on the relative role of urban greenspaces and heavily-built sites. We considered a country-wide approach, including 24 different sized Mexican cities. Our aims were to describe the urban bird diversity in focal cities and further assess the r...

Urbanization has been recognized as one of the most widespread threats to biodiversity. However, the response of wildlife to urbanization differs among groups, with many species being able to persist, adapt, and even thrive in these novel ecosystems. With the aim of assessing the response of avian communities in a neotropical green city, we evaluat...

In this concluding chapter, we underline the main conclusions of the reviewed topics regarding avian ecology in urban Latin America, namely: an updated literature review (Chap. 2); species richness and composition (Chap. 3); demography and population dynamics (Chap. 4); relationships with urban infrastructure (Chap. 5); behavior (Chap. 6); urban th...

Following a massive migration toward cities, more than half of the total human population is now urban. Given the unbalanced metabolism of urban systems, urbanization has been recognized to be a major ecological driver with worrisome consequences at different spatial and temporal scales. Such an environmental issue has drawn the attention of ecolog...

Among human activities, urbanization represents one of the most worrisome for biodiversity due to the intensity and long-term effects in the place where a city develops, as well as their indirect effect in its area of influence. Birds are one of the most studied groups to assess the impacts that urbanization has on biodiversity, but there is a lag...

This book gathers a representative sample of the relevant knowledge related to the ecology, behavior, and conservation of birds in urban Latin America. Latin America is one of the most biodiverse regions of the world, yet it is still understudied. Although it concentrates most of its population in rapidly growing cities under considerable economic,...

The natural area Sierra de Quila is located at the western part of the Transmexican Volcanic Belt. It has an extension of 14,168 ha and is legally protected since 1982. It includes six types of vegetation and between 138 and 149 bird species. As result of monthtly surveys on this area, between January 2009 and December 2010, we recorded for the fir...

Urbanization has been considered as a major threat to biodiversity, making its ecology of increasing interest. Many urban ecology studies have been developed in a short time-scale, measuring real-time patterns. However, long-term studies are imperative to understand the responses of some species to the urbanization process. In this study, we aimed...

Birds are considered excellent bioindicators in urban areas. Some of the ecological processes behind bird ecological patterns in urban areas have been related to birds’ capacities to shift their behaviors. In this brief communication, we report a nest of Azure-crowned Hummingbird (Amazilia cyanocephala) built on a metallic structure that connects t...
