“…Most studies in this region have not, however, considered long-term trends in urban bird populations. Exceptions include a 23-year study on the impacts of surrounding urbanization on wetland birds (Ferrarini et al 2021), a 26-year study on changes in species composition in a single park (Battisti and Dodaro 2016), and an 8-year study on population changes of alien parrot species (Hernández-Brito et al 2022).…”

Context Urbanization and its associated impacts on biodiversity are increasing globally. There is a need to enhance our understanding of species responses to inform strategies for sustainable urbanization. Objectives Three extensive bird monitoring campaigns took place over the last three decades in the city of Naples, Italy, providing a comprehensive longitudinal dataset to analyse occurrence trends of urban birds. We aimed to assess both species-specific and assemblage-level changes in urban birds according to land cover dynamics. Methods We extracted bird data for the periods 1990–95, 2000–05, and 2014–18, and explored the spatial and temporal relationships between bird presence/avian assemblage composition, and land cover variation. Results The species richness of breeding birds remained stable over time, despite a notable species turnover, influenced by changes in the species’ key land cover classes. Species associated with forest and urban land cover tended to colonise the area, while those dependent on abandoned and cultivated areas decreased or went locally extinct. Birds changed their degree of dependence upon their key habitat type over time, as species from marginal and open habitat types needed larger amounts of habitat to persist within the area, while forest species showed an opposite trend. Conclusions Habitat-driven changes in avian assemblages within the urban landscape led to an increase in forest-associated species, and a decrease in birds associated with declining habitat types. Our findings may inform urban planning to promote more wildlife-friendly cities, which for our study area should prioritise open and marginal habitats.

“…A few cost reports are historical, such as damage to agriculture by the Eurasian blackbird Turdus merula in Tasmania during the first half of the last century [ 53 ], but most are from 2000 to present. The sharp increase in reports since 2010 might arise because some alien bird species (particularly monk parakeets Myiopsitta monachus and ring-necked parakeets Psittacula krameri ) are rapidly becoming more widespread [ 54 ], and are being managed with local-scale actions. For example, between 2015 and 2018 there were 75 different cost reports for the management of monk parakeets at 34 different sites in Catalonia, Spain.…”

The adverse impacts of alien birds are widespread and diverse, and associated with costs due to the damage caused and actions required to manage them. We synthesised global cost data to identify variation across regions, types of impact, and alien bird species. Costs amount to US$3.6 billion, but this is likely a vast underestimate. Costs are low compared to other taxonomic groups assessed using the same methods; despite underreporting, alien birds are likely to be less damaging and easier to manage than many other alien taxa. Research to understand why this is the case could inform measures to reduce costs associated with biological invasions. Costs are biassed towards high-income regions and damaging environmental impacts, particularly on islands. Most costs on islands result from actions to protect biodiversity and tend to be low and one-off (temporary). Most costs at mainland locations result from damage by a few, widespread species. Some of these costs are high and ongoing (permanent). Actions to restrict alien bird invasions at mainland locations might prevent high, ongoing costs. Reports increased sharply after 2010, but many are for local actions to manage expanding alien bird populations. However, the successful eradication of these increasingly widespread species will require a coordinated, international response.

“…Today, monk and ring‐necked parakeets are abundant, coexist as aliens and continue to spread in many areas of the Iberian Peninsula (e.g. [Hernández‐Brito et al, 2022]). These species present different ecological traits that make them good complementary study models.…”

Aim Concern about the impacts of biological invasions has generated a great deal of interest in understanding factors that determine invasion success. Most of our current knowledge comes from static approaches that use spatial patterns as a proxy of temporal processes. These approaches assume that species are present in areas where environmental conditions are the most favourable. However, this assumption is problematic when applied to dynamic processes such as species expansions when equilibrium has not been reached. Location Iberian Peninsula. Taxon Birds. Methods In our work, we analyse the roles played by human activities, climatic matching and spatial connectivity on the two main underlying processes shaping the spread of invasive species (i.e. colonization and extinction) using a dynamic modelling approach. We use a large data set that has recorded the occurrence of two invasive bird species—the ring‐necked (Psittacula krameri) and the monk (Myiopsitta monachus) parakeets—in the Iberian Peninsula from 1991 to 2016. Results Human activities and climate matching play a role on species range dynamics. Human influence and urbanization were the most relevant factors explaining colonization. Additionally, an effect of climate matching was found. Persistence (the inverse of extinction) was mainly affected by human influence for the monk parakeet and by the extent of urban environments for the ring‐necked parakeet. Main conclusions Human activities play a major role not only on colonization of new locations, but also on persistence during range expansion. Additionally, natural processes—notably climate matching—also affect new colonizations. These findings add to our understanding of the mechanisms that might allow alien species to expand their geographic range at new locations and might help to improve our capacity to assess invasion risks and impacts accurately.
