“…Motion‐triggered cameras took 104 photographs of 10 different species of mammalian predators (Table 2). White‐tailed deer ( Odocoileus virginianus ), which have recently been documented as opportunistic nest predators (Pietz & Granfors 2000; Ellis‐Felege et al 2008), were detected most frequently.…”

In the eastern United States, land-use and climate change have likely contributed to declines in the abundance of Neotropical migrant birds that occupy forest interiors, but the mechanisms are not well understood. We conducted a nest-predation experiment in southern Appalachian Mountain forests (North Carolina, U.S.A.) during the 2009 and 2010 breeding seasons to determine the effects of exurban development and temperature on predator presence and the average number of days until eggs in an artificial nest were disturbed by predators. We baited artificial nests with quail (Excalfactoria chinensi) eggs and monitored them for 18 days. We used clay eggs, track plates, and motion-triggered cameras to detect and identify nest predators. The average number of days a nest was undisturbed decreased as mean temperature increased and, to a lesser extent, as the density of buildings increased. Nests on the ground were more often depredated than those in trees, likely due to increased predation by opossum (Didelphis virginiana) and other carnivores. Raccoons (Procyon lotor), opossums, corvids (Corvus brachyrhynchos and Cyanocitta cristata), chipmunks (Tamias striatus), black bears (Ursus americanus), and domestic cats (Felis catus) were the most commonly detected predators. Presence of these predators did not vary as a function of mean temperature. Domestic cats and corvids were detected more frequently in plots with high rather than low densities of buildings. Forest-interior specialists and Neotropical migrants often nest in cool, high-elevation areas with low housing density. These bird species, especially those that nest on the ground, may be most vulnerable to increased nest predation if temperature and exurban development increase at higher elevations as anticipated.

“…Pietz and Granfors 2000b [0.08]). Because nest predation by White-tailed Deer is thought to occur opportunistically (Pietz and Granfors 2000b), the relatively high 2 , National Park Service 2009) likely contributed to the high rate of nest predation by White-tailed Deer. In addition, competition for food among White-tailed Deer in a high-density situation might make it more likely for these animals to consume high-protein, calorie-dense foods such as eggs and chicks when opportunities occur.…”

Populations of grassland birds are declining in the Northeast due to habitat loss and fragmentation. Fragmentation of grasslands can contribute to lower breeding success of grassland birds by altering local predator communities. Using miniature video cameras, National Historical Park in southeastern Pennsylvania. Estimated nest-success probability for Sturnella magna n = 7) and similar to estimates from the Midwest, but slightly lower than other studies in the Northeast. Nest success for Spizella pusilla (Field Sparrow; 0.77 [0.31-0.98, n = 8]) and Agelaius phoeniceus n = 10]) was higher than estimatesThe primary predator was Odocoileus virginianus (White-tailed Deer; 38% of nest predation events) followed by Vulpes vulpes (Red Fox; 25%); Procyon lotor (Raccoon; 13%), and a probable Mustela sp. (weasel; 13%). I never detected nest predation by small mammals or snakes, which are important nest predators in the Midwest. The impact of White-tailed fully understand local predator-prey community dynamics.

“…Technically, the young bird that left the nest would have been considered a fledgling. In this case, however, the fate of the "fledgling" was known because the deer caught it while it was still in camera view; it survived <10 sec outside the nest (Pietz and Granfors 2000b). Forced fledging occurred at nearly 20% of our nests that were visited by predators and accounted for about 10% of young that were classified as fledged (Table 1.2; Pietz et aI., chapter 4, this volume).…”

“…In such cases, the young were clearly motivated to leave the nest by the presence of the predator, but classifications of nest and nestling fates remain ambiguous. At one Savannah Sparrow nest in North Dakota, a 7-d-old nestling fled the nest while a white-tailed deer (Odocoileus virginianus) was eating its nest mates (Pietz and Granfors 2000b). Technically, the young bird that left the nest would have been considered a fledgling.…”

In the mid-1990s, researchers began to adapt miniature cameras to video-record activities :rt cryptic passerine nests in grasslands. In the subsequent decade, use of these video surveillance systems spread dramatically, leading to major strides in our knowledge of nest predation and nesting ecology of many species. Studies using video nest surveillance have helped overturn or substantiate many long-standing assumptions and provided insights on a wide range of topics. For example, researchers using video data have (1) identified an extensive and highly dynamic predator community in grasslands that varies both temporally (e.g., by time of day, nest age, season, year) and spatially (e.g., by habitat, edge, latitude); (2) shown that sign at nests is unreliable for assigning predator types and sometimes nest fates; (3) contributed to the 4
