“…Aggressive interactions and nest usurpations have been recorded among numerous other cavity nesting species Robertson 1991, Strubbe andMatthysen 2009). For example, Meek and Robertson (1994) noted that Tree Swallow usurped nests on 22% of 64 Eastern Bluebird territories, similar to the frequency in the current study, but because many of those territories contained multiple, clustered boxes, the risk of take-overs is difficult to compare directly.…”

“…Certainly, in the UK and the rest of temperate Europe the introduced rose-ringed parakeet Psittacula krameri has established in many cities with its success at least in part associated with access to urban bird feeders (Clergeau and Vergnes, 2011). This species not only outcompetes many native species for food but also for nest sites (e.g., Strubbe and Matthysen, 2009). However, we urge caution in uncritically assuming that introduced avian species always have negative implications.…”

Garden Bird Feeding: Insights and Prospects from a North-South Comparison of This Global Urban Phenomenon

Intentional feeding of wild birds in gardens or backyards is one of the most popular forms of human-wildlife interactions in the developed world, especially in urban environments. The scale and intensity of bird feeding are enormous with mainly birdseed consumed daily by a range of species. This represents a subsidy to natural diets of birds attracted to the feeders and typically involves novel dietary components. Yet, relatively little is known about how it influences the behavior and ecology of the species visiting feeders. In part, research has been hampered by logistical difficulties of working in urban areas but studies have demonstrated powerful influences on behavior and phenology of avian breeding, the spread of disease, and the structure of avian communities. Here, we compare bird feeding between Northern and Southern Hemispheres as a means of exploring how similarities and differences in avian responses might inform knowledge of this global urban phenomenon. We start by tracing its origins to north-western Europe and how its expansion has occurred before considering how geographical differences in feeding practices and attitudes map onto bird feeding "on the ground." We explore some of the major emerging themes of recent interest, including why citizens are motivated to feed birds, whether birds become fully dependent on food supplements, the role of feeding in avian disease transmission, and how feeding changes urban bird communities. By proposing that scientists work in collaboration with the public providing food to birds, we pose key research questions that need to be answered urgently and suggest accompanying experimental approaches to do so. These approaches are essential if we are to improve our understanding of how bird feeding shapes the behavior, ecology, movements, and community structure of urban birds. Our hope is that through such citizen science we will be able to provide advice as to location-relevant practices that should maximize benefits to both urban biodiversity and human well-being, and minimize potential adverse impacts. We demonstrate that bird feeding is important for urban biodiversity conservation, community engagement, and in establishing personal connections with nature and their associated benefits.

“…Between 1986 and 2008, 150,000 Ring-necked Parakeets have been exportted from Senegal alone (CITES), but failed to establish populations in Europe so far. In Belgium, there is some evidence for competition between Ring-necked Parakeets and native Nuthatches (Sitta europaea) [21]. The Ringnecked Parakeet is listed as one of the '100 worst invasive species' in Europe and as a potential competitor to the European Starling [4].…”

Abstract:In general, non-native bird species may competitively exclude native species from nest sites. The potential resource conflict between a native and an introduced bird species, the native European Starling (Sturnus vulgaris) and the introduced Asian Ring-necked Parakeet (Psittacula krameri), was inferred from hole occupancy in parks of the German Upper Rhine Valley (Wiesbaden, Mannheim, Schwetzingen, Edingen-Neckarhausen), where Ring-necked Parakeets have been known to occur for 15 to 35 years. Only 2.2 % of trees (n = 3487) had cavities with an entrance diameter ≥4 cm. The number of unoccupied tree holes was high, representing 71 % of 639 recorded cavities. A niche separation corresponding to tree size and tree species preferred by both bird species could be detected. Starling preferred trees with a diameter of 0.75 ± 0.30 m, whereas Ring-necked Parakeet favoured ones with 1.16 ± 0.36 m in diameter. Both bird species were the most abundant hole-nesters in the examined cavities. Ring-necked Parakeets preferred Platanus x hispanica, which hosted 57 % of all broods for the parakeet, but did not use Acer pseudoplatanus. Starling favoured Quercus robur with 25 % of all broods, followed by A. pseudoplatanus with 19 %. P. x hispanica showed the highest numbers of cavities with 227 in total and a median of 3 holes per tree, partially produced by Ring-necked Parakeet. The largest colony-in-one-tree in this study was 9 for P. krameri and 5 for S. vulgaris. In this study, Starlings took over two nests from Ring-necked Parakeets, with one case vice versa, and Honeybees took over one active Ring-necked Parakeet nest.
