“…Landscape diversity has been shown to be an important factor to facilitate forest bird occurrence in agricultural landscapes (e.g., Ferraz et al 2012), and also to promote forest bird species richness (e.g., Petit and Petit 2003;Bennett et al 2006). Scattered trees promote higher heterogeneity and act as stepping-stones for forest species moving through agricultural landscapes (e.g., Fischer and Lindenmayer 2002;Uezu et al 2008;Fahrig et al 2011;Prevedello et al 2018;Vogel et al 2018). Boesing et al (2017) observed that in pasture with low heterogeneity (i.e., with few scattered trees) the occurrence of forest-dependent birds were lower in comparison to permeable coffee plantations.…”

Sugarcane and cattle pastures are two of the most widespread and economically important agricultural landscapes. However, in Brazil, they have not been properly investigated for their importance to native birds and wildlife conservation. Thus, we aim to characterize and compare bird assemblages of sugarcane and cattle pastures; and understand how landscape features within both habitats influence bird assemblages. We surveyed birds in both agricultural habitats over one year, and then investigated the relationship between species richness and composition with landscape diversity, matrix permeability, and the size and distribution of natural forests close to both habitats. We observed 132 species in cattle pastures and only 72 in sugarcane (48% bird community similarity). We further evaluated the richness and relative abundance of avian ecological groups, including habitat specialists and habitat generalists, insectivores, omnivores, granivores and frugivores. All avian groups were higher in pastures, the habitat where landscape heterogeneity and number of scattered trees was higher. Our results show that overall increasing landscape heterogeneity favors an assemblage with higher richness and composed by species with more diverse ecological functions. Therefore, we argue in favor of management practices that incorporate heterogeneity in agricultural landscapes, mainly in sugarcane fields where a homogeneous scheme has been used. Otherwise, the potential of agricultural landscapes for bird conservation will be highly hindered, particularly if the sugarcane sector expands to other agricultural lands.

“…For instance, a recent comparison of biodiversity levels between more than 100 cities around the world revealed that bird and plant species densities differ significantly between cities and are best explained by a city's urban land cover, age of the urban area, and intact urban vegetation cover (Aronson et al 2014). Few studies have investigated the importance of man-made structures to bird communities in urban landscapes and the implications for ecological restoration in urban ecosystems (Fisk 1978, Mainwaring 2015, Pike et al 2017, Vogel et al 2018. For example, studies suggest that urbanization favors resident birds more than it does for migrants (e.g., Lancaster and Rees 1979) and omnivores (Dickman and Doncaster 1987), or species with broad environmental tolerance (Bonier et al 2007).…”

Our understanding of how birds use human supplementary resources, especially artificial structures and patchy vegetation within urban areas, is limited. Our study compared the use of artificial structures versus natural vegetation by birds in built-up areas in the Cape Coast Metropolitan Assembly (CCMA) in the central region of Ghana. Using point count technique, we recorded bird species and the activities performed as well as the substrates they use in residential and commercial areas within the CCMA. We found that the mean bird abundance that used artificial structures did not differ significantly from those that used natural vegetation. The mean species richness that used artificial structures was found to differ significantly from those that used natural vegetation. The study also found a significant difference in activities performed by bird species and the substrate type used for daily life activities. Across species, birds showed preference for trees, shrubs, and natural vegetation structures for perching, feeding, and singing, whereas artificial structures such as billboards, telecommunication masts, ceilings of buildings, pylons, buildings, opening in street lights, and windows of buildings were preferred for nesting. These results demonstrate that although not a replacement for natural resources, artificial structures, when combined with natural vegetation, could contribute significantly to the survival of urban birds. Conservation practitioners could encourage urban mosaic landscapes of built and green spaces to conserve and restore populations of birds.
