“…However, they worked along a short distance gradient (less than 1·5 km) and only differences within 0·2 km from the woodland area were significant. This represents a classic fringe effect (De Graaf, Geis & Healy 1991;Chou & Soret 1996), where proximity of resources or habitat explains the presence of birds.…”

Summary1. The species diversity of adjacent landscapes influences the conservation or restoration of several animal groups in urban areas, but the effect on birds is unclear. To address this question, we compared bird species richness (BSR) and community composition between periurban (area surrounding the town) and urban (suburban and centre areas) landscapes across three spatial scales. 2. At a large biogeographical scale (temperate and boreal climatic zone), relationships between the BSR of urban areas and their surrounding landscapes were examined in a meta-analysis of 18 published studies. In general, BSR was negatively correlated with latitude and urbanization. The BSR of suburban and centre landscapes correlated positively with the BSR of periurban landscapes. However, latitudinal effects were also involved, as BSR in urban and periurban landscapes declined as town latitude increased. Similarity indices were low (50%) between periurban and centre bird communities. 3. At a regional scale, we assessed winter bird data from several towns within three regions of temperate and boreal countries (western France, northern Finland and eastern Canada). The type of periurban landscape, number of inhabitants and town diameter did not affect BSR. BSR was similar between the cities of a given biogeographical area. Bird communities were more similar between similar habitat types of different cities than between different habitats of the same city. 4. At a local scale, we tested the influence of proximity to the periurban landscape on BSR in parks of western French towns of different size. Neither BSR nor community similarity changed in relation to the distance of the park from the periurban landscape. 5. Guild composition according to diet and feeding habitat did not vary between urban and periurban locations at regional or local scales. 6. We conclude that, at regional and local scales, urban bird communities are independent of the bird diversity of adjacent landscapes, and that local features are more important than surrounding landscapes in determining BSR. Whatever the biodiversity quality of the periurban landscape, site-specific actions such as shrub and tree planting, water restoration and increasing vegetation diversity can change bird diversity in towns and improve the quality of human-wildlife contacts.

“…Transect length varied according to gradient extension. Birds were surveyed using a fixed 50-m radius point-count method (DeGraaf et al, 1991;Ralph et al, 1996;Melles et al, 2003). The spacing of point-count sites varied between 150 and 200 m (in villages and small towns), 250 m (in intermediate and large towns) and 600 m (in the largest town).…”

“…A survey route zigzagged through each plot to allow us to inspect the backyards of the houses and buildings. This kind of transect count reduces many problems associated with counting birds in urban areas, such as varying noise and visibility (DeGraaf et al 1991). Surveys were not conducted during rainy or extremely windy conditions (greater than 20 mph).…”
