“…As urbanization is progressing rapidly throughout the biodiverse Neotropics (Pauchard & Barbosa, ), research on biodiversity assemblages in the urban areas of this region is growing increasingly important to inform local conservation priorities (Socolar, Gilroy, Kunin, & Edwards, ). Our study, one of only a few with an urban focus conducted in the Neotropics, demonstrates that many species are found within towns and cities, and reaffirms that urban bird assemblages are influenced by landcover type (Amaya‐Espinel et al, ; Dale, ; Fontana et al, ; Kang, Minor, Park, & Lee, ; Leveau & Leveau, ; MacGregor‐Fors et al, ; Pellissier, Cohen, Boulay, & Clergeau, ; de Toledo, Donatelli, & Batista, ; Villegas & Garitano‐Zavala, ). As the majority of land around Georgetown is agricultural, drawing comparisons with bird communities inhabiting natural landcovers in close proximity to the city was not possible.…”

“…Furthermore, in accordance with our findings, snowy egret and whimbrel have been previously recorded having a strong association with coastal urban habitats (Seigel, Hatfield, & Hartman, ; Tejera & Rodríguez, ). Aside from coastal bluespace, the managed greenspace landcover had the highest number of indicator species, including tropical kingbird and cattle egret, both of which have previously been observed in urban greenspaces (Leveau & Leveau, ; Phalen et al, ). Moreover, the high indicator value of blue‐black grassquit within unmanaged greenspace is not surprising, given that they are typically found within high grass and scrubland throughout the Neotropics (Wilczynski, Ryan, & Brenowitz, ).…”

Bird communities across varying landcover types in a Neotropical city

Urbanization poses a serious threat to local biodiversity, yet towns and cities with abundant natural features may harbor important species populations and communities. While the contribution of urban greenspaces to conservation has been demonstrated by numerous studies within temperate regions, few consider the bird communities associated with different landcovers in Neotropical cities. To begin to fill this knowledge gap, we examined how the avifauna of a wetland city in northern Amazonia varied across six urban landcover types (coastal bluespace; urban bluespace; managed greenspace; unmanaged greenspace; dense urban; and sparse urban).We measured detections, species richness, and a series of ground cover variables that characterized the heterogeneity of each landcover, at 114 locations across the city. We recorded >10% (98) of Guyana's bird species in Georgetown, including taxa of conservation interest. Avian detections, richness, and community composition differed with landcover type. Indicator species analysis identified 29 species from across dietary guilds, which could be driving community composition. Comparing landcovers, species richness was highest in managed greenspaces and lowest in dense urban areas. The canal network had comparable levels of species richness to greenspaces.The waterways are likely to play a key role in enhancing habitat connectivity as they traverse densely urbanized areas. Both species and landcover information should be integrated into urban land-use planning in the rapidly urbanizing Neotropics to maximize the conservation value of cities. This is imperative in the tropics, where anthropogenic pressures on species are growing significantly, and action needs to be taken to prevent biodiversity collapse.

“…La interacción entre el tamaño y la distancia de las 12 AV satelitales al área verde más grande de San Salvador, no explicó significativamente la variación observada en la riqueza, diversidad, y equitatividad de aves en el centro urbano. Se ha planteado que dicha teoría (MacArthur y Wilson 1967) falla al no evaluar factores como: el efecto de borde, el efecto de la matriz donde está inmerso el parche, la distancia del borde de la ciudad, la intensidad del paso de peatones, la intensidad del paso de automóviles, entre otros, que pueden en conjunto explicar de mejor forma la variación de la avifauna y de la biodiversidad en general, en centros urbanos (Laurance 2008, Ortega-Álvarez y MacGregor-Fors 2009, Barbosa et al 2011, MacGregor-Fors y Ortega-Álvarez 2011, Leveau 2013, Leveau y Leveau 2016.…”

La creciente urbanización ha propiciado que los ecosistemas naturales sean constantemente sustituidos por paisajes urbanos, proceso muy notorio en El Salvador, debido a su pequeña extensión territorial (21.041 km²) y su alta densidad poblacional (291 hab/km²). Realizamos un inventario en 12 áreas verdes urbanas, con diferentes tamaños, formas y distancia con respecto al área boscosa más grande de la zona metropolitana, basados en la teoría de biogeografía de islas de McArthur y Wilson (1967). Evaluamos si la riqueza, diversidad y equititavidad de aves se relacionaba con el tamaño y la distancia de las áreas verdes y si la forma de las mismas tenía algún efecto sobre la riqueza de aves. Registramos un total de 20 especies de aves y las clasificamos según su dieta (generalista y especialista). Observamos que la distancia no influyó en la riqueza de aves y que no hubo interacción entre las variables tamaño y distancia, pero que sí influyó el tamaño del área verde. La riqueza de aves con dieta restringida incremento en las áreas verdes más circulares que en las de forma más irregular. Concluimos que en el centro urbano de San Salvador, la presencia de áreas verdes grandes y circulares aporta más a la riqueza de aves de dieta especialista, que áreas de similar tamaño pero de forma irregular. Sin embargo, áreas pequeñas aportan más a la riqueza de aves que poseen esa dieta, si su forma es más circular

Species and numeric composition of bird communities were analyzed in parks of Lviv based on results of monthly censuses on 20 linear transects on eight study plots. During the year, 79 bird species that belong to eight taxonomic orders were registered Birds' diversity was assessed by species number and Simpson index and it varies throu ghout the year and denotes higher level during the breeding season. Similarly, birds' density is the highest in breeding season, but it also has a less expressed peak in winter period. This shows that biotopical preferences to be presented in urban greenery of parti cular birds are especially notable only while breeding, but in non-breeding season those birds stay resident in scale of the city though disperse in other habitat types. Between-months, stability of species composition (assessed by Jaccard index) and numeric composition (by Bray-Curtis index) was analyzed. Communities were the most stable during the breeding season as birds are related to their nesting sites. According to zoogeographic classification, European species dominate during all months. Siberian, Transpalearctic and Medite rranean species also play role in forming of the community structure. The main food resources type which compensates energy demands of birds during the breeding season is inver te brates; this shows the importance of birds in controlling the abundance of invertebrates in urban ecosystems. Seeds are also important food resour ce types, especially during the non-breeding period. Abundance variability of part of spe cies is related with season. Three main groups of these species were defined: breeding migrants (mainly songbirds such as Fringilla coelebs, Erithacus rubecula, Sylvia atricapilla, Phylloscopus collybita etc., also Columba palumbus), wintering migrants (Spinus spinus, Turdus viscivorus, Bombycilla garrulus, Pyrrhula pyrrhula) and residents (typical synanthropic species whose numbers vary: Turdus merula, Coccothraustes coccothraustes, Troglodytes 80 O.

Bird surveys were conducted on each linear transect every month during a period from December 2017 to November 2018. Linear transects method was chosen and data obtained using this method are the most representative concerning the whole community structure [18,3]. Birds were located at the same distance (50 m on both sides from observer) in all months.
