“…feral pigeons, which represent the bulk of the prey delivered to the nest in the study area; Brambilla et al 2005) and is consistent with the increasing adaptation to human-modified habitats shown by several birds of prey in the course of the 20th century (Bird et al 1996). In fact, peregrines readily breed in quarries, towns and cities all over the world, provided that suitable nest sites are available (Cramp and Simmons 1980;Ratcliffe 1993;Moore et al 1997;Monneret 2000). Moreover, in the study area, peregrines often oversummer in villages together with newly fledged juveniles, resting on taller buildings (such as churches and powerline towers) and preying on urban pigeons, swifts, doves and starlings (M. Brambilla et al, unpublished data).…”

“…Despite its wide distribution range, few studies have dealt with habitat selection in European peregrine populations (Moore et al 1997;Gainzarain et al 2000;Sergio et al 2004). Peregrine populations are recovering after a dramatic worldwide decrease due to organochlorine pollutants (exacerbated by direct human persecution; see Rockenbauch 1998Rockenbauch -2002 and related comments by Wegner et al 2005), which mainly occurred between 1950 and 1975 in Western Europe and North America (Ratcliffe 1993;Kauffman et al 2004;Wegner et al 2005).…”

Factors affecting breeding habitat selection in a cliff-nesting peregrine Falco peregrinus population

We studied factors affecting breeding habitat selection in a population of cliff-nesting peregrines Falco peregrinus across multiple spatial levels (cliff site, cliff context and land-use of the surrounding landscape), over a 2,100 km 2 study area in the Alps (Italy and Switzerland). We detected 30 breeding pairs (density: 1.43 territorial pairs/100 km 2 ), whose territories were uniformly distributed over the study area. We compared 15 habitat features characterising occupied cliffs and 30 randomly selected unoccupied cliffs by means of stepwise forward logistic regression and hierarchical partitioning. The logistic regression analysis showed that occupied cliffs were longer (horizontal length), steeper, and had a greater extension of urban areas in the surrounding landscape compared to non-occupied cliffs. The model had a discrimination ability of 0.95. Hierarchical partitioning indicated that the logistic regression model was appropriate. Neither the distance of cliffs to the nearest site occupied by a potential competitor and predator, the eagle owl Bubo bubo, which occurred at a low density (0.67 pairs/100 km 2 ), nor the distance to the nearest site occupied by peregrines had any effect on the cliff suitability model. Therefore, habitat selection in cliff-nesting peregrines was mainly influenced by cliff site features and surrounding landscape characteristics, whereas the proximity to conspecifics and to an intraguild predator had no apparent effects on peregrine settlement in our study population.

“…Nesting on smokestacks has been encouraged in the Midwest through the provision of nest boxes, whereas this has rarely been done in the east. All quarry nests in our study were in Quebec, but use of such sites has previously been documented in Britain (Ratcliffe ), Ireland (Moore et al ), Australia (White et al ), and Alaska (Ritchie et al ). White et al () postulated that these were secondary quality nests, primarily used by inexperienced individuals unable to compete for superior territories.…”

The peregrine falcon (Falco peregrinus) population in eastern North America has grown significantly since the early 1980s, especially in urban areas, but few studies have assessed the factors that influence productivity. We reviewed all documented nesting attempts from southern Ontario, Quebec, Massachusetts, New Jersey, and Pennsylvania from 1980 through 2006 to evaluate these factors. Of 801 nesting attempts, 663 were successful, producing a total of 1,613 young. Mean productivity ranged from 1.7 young fledged per nesting attempt in New Jersey to 2.9 in Quebec. Peregrines nesting in quarries or on buildings had higher productivity than those using marsh towers or bridges, but productivity did not differ overall between urban and rural sites. Nests with overhead cover had higher productivity than those without, as did nests in trays or boxes compared to sites without any human‐provided nesting aids. Peregrines favored nest sites facing east to south, but productivity did not vary significantly with direction. Several adults have contributed disproportionately to the growth of the eastern population, with just 5 females and males accounting for 8% and 9% of all young fledged, respectively. Of 160 documented mortalities, we identified cause of death for 118, with the most common being collisions with buildings (36%), vehicles (9%), aircraft (8%), and power lines (8%). In many urban areas, grounded fledglings are rescued and returned to higher perches. Of 85 individuals from southern Ontario that were rescued, at least 8 have subsequently bred, producing 65 known offspring. Although peregrines have been thriving in eastern cities, continued management effort may be required for them to maintain their level of success, with key measures including provision of appropriately located nest boxes and rescue of grounded fledglings. © 2014 The Wildlife Society.

“…Therefore, other facets and opportunities regarding the restoration of quarries need to be explored (Beneš et al ; Tropek & Konvicka ). Other studies have also found that quarries provide conditions for the establishment of unique communities (butterflies, Beneš et al ; spiders, Tropek & Konvicka ) or species (Peregrine Falcon—Moore et al ; Eagle Owl—Sándor & Ionescu ; Turkish Gecko—Salgueiro et al ), either promoted by pioneer successional herbaceous stages or rocky habitats. In these cases, classical reclamation practices may have had adverse effects.…”

Highly degraded habitats such as quarries often require active restoration efforts, but classical reclamation practices may undermine the occurrence of species that are locally rare or of conservation concern. We argue that some species can benefit from quarry landform whenever the presence of certain elements in the surroundings is preserved. We uncover the role of quarry landforms as providers of artificial habitat for the establishment of a bird of rocky habitats—the Black Redstart (Phoenicurus ochruros). We identified and monitored the location of territories of this species in seven quarries and their surroundings, over an entire breeding season. A multiscale approach was applied in order to take into account optimal spatial scales of response of the species to each habitat descriptor. We found this species mainly associated with quarried areas embedded within an inhospitable landscape. Mean slope, built‐up area, and number of habitats were important descriptors for Black Redstart territory location. Black Redstart territories are constrained at two scales. Core areas (0.25 ha) are mainly defined by optimal conditions for nest site location, where inaccessible rocky slopes provide safer places for nesting. At a larger scale (>2.00 ha) territories must enclose other land uses that deliver access to food supplies and offer good display positions to signal the limits of territories, allowing control of possible intruders. Localized actions aiming to maintain novel elements may result in the preservation of species such as the Black Redstart.
