“…Street trees and green urban areas in Madrid provide foraging opportunities for common wood pigeons throughout the year. The diversity of trees exploited, the use of non-native plants with contrasting phenological patterns compared with the local flora and the longer fruiting periods of some trees constitute key factors to explain the successful exploitation of the common wood pigeon in the city, as observed in other species inhabiting cities [ 22 , 49 , 55 , 56 ]. This approach allowed us to identify the consumption of organs such as roots, leaves, seeds, fruits and flowers, which are difficult to identify visually in faeces.…”

Urban configuration and food availability influence birds’ foraging behaviour and constitute key factors for understanding how they exploit cities. Here, we conducted a field survey in the city of Madrid (Spain) from winter 2021 to autumn 2022 to understand how the common wood pigeon ( Columba palumbus ) exploits the food resources provided by urban parks and streets across different seasons. The proportion of observations away from parks increased during winter and spring, and the proportion of observations of wood pigeons eating on the ground was the greatest in summer. The common wood pigeon fed from 45 tree species, 60% of which were exotic ornamental species. Most tree species used as food sources coincided with those widely planted in parks, streets and avenues. The preferred trees varied throughout the year, with a greater incidence of exotic species in winter and spring. Our results show that the diversity of trees available in cities and the use of non-native plants with contrasting phenological patterns compared with the local flora are crucial elements in explaining the successful establishment of the common wood pigeon in the city.

“…The different prevalence trends between monk and rose-ringed parakeets could be due to the feeding behaviour of each species and, thus, their interactions with other species. While monk parakeets feed mostly on the ground ( 38 ), rose-ringed parakeets do so in trees more frequently ( 39 ). Feeding on the ground gives monk parakeets the chance to interact with feral pigeons and then share pathogens with them, mainly respiratory ones.…”

IntroductionThe introduction of invasive species into an ecosystem could result in biodiversity loss and the spread of infectious agents that could cause re-emergent or emergent zoonotic diseases. Monk parakeets (Myiopsitta monachus) and rose-ringed parakeets (Psittacula krameri) are considered widespread invasive exotic species in urban habitats from the Iberian Peninsula. The aim of this study was to assess the presence of relevant infectious agents in wild parakeets captured in urban parks in Madrid and Seville (Spain).MethodsA total of 81 cloacal samples were collected and analysed using molecular techniques.ResultsThe prevalence of infectious agents varied between parakeet species: 9.5% of monk parakeets and 15% of rose-ringed parakeets were positive for enteropathogenic E. coli (EPEC), 13.3% of rose-ringed parakeets for avian influenza virus (AIV), 3.3% of rose-ringed parakeets for Newcastle disease virus (NDV), and a 23.8% of monk parakeets for Chlamydia psittaci.DiscussionAll C. psittaci-identified isolates were classified as B, E, or E/B genotypes, indicating transmission from wild urban pigeons to parakeets. These results highlight the need for monitoring parakeet populations due to the implications for human and animal health.

“…This study was conducted in Catalonia, Spain, on the northeast coast of the Iberian Peninsula. Monk parakeets were ringed as adults or chicks in Barcelona city, with the majority of fieldwork conducted in Ciutadella Park, a large (30 ha) central park in the city that contains the city's zoological gardens and a large public access area of highly managed native and exotic vegetation (Postigo et al, 2021). Ciutadella Park is the site of the first record of monk parakeet nests in Barcelona (Batllori and Nos, 1985) and now contains a high density of monk parakeet nests.…”

Invasive species threaten biodiversity all around the world and for this reason, identifying the causes and mitigating their effects is a priority in conservation biology. One of the most important factors when dealing with invasive species is dispersal, because the distribution of dispersal distances among members of a population can greatly affect the rate of spread of these invasive populations. Long distance dispersal events have a disproportionately large influence on dispersal kernel estimations, but because of restricted spatial sampling scales they are difficult to detect. Here we use an extensive database of 3,114 monk parakeets ringed in Barcelona city since 2002 as part of an extensive control program across Catalonia where 3,460 birds have been captured since 2013. Our aim was to describe these long–distance movements of monk parakeets. We recorded dispersal distances of over 10 km for a total of eight individuals. Long–distance dispersions were in all directions and both males and females were involved. While some individuals moved in their first year, others delayed dispersal several years. Given that long–distance dispersal events can have a large influence on the rate of range expansion of invasive species this information can be of great utility when modeling the dispersal and spread of the species.
