“…Two heron carcasses and one live heron were found entangled in monofilament line hanging from several black cottonwoods (Populus balsamifera) near the Mary Hill Bypass, Port Coquitlam colony (Gebauer 1995a). Bird entanglements were recognised by Parnell et al (1988) as being a frequent human-caused accident.…”

“…High dioxin levels apparently resulted in the presence of edema and a depression of growth. Other studies that have reported effects of organochlorine and metal contaminants on Great Blue Herons include Henny and Bethers (1971); Parnell et al (1988), Speich et al (1992) and Spalding et al (1994).…”

“…Numerous descriptive and experimental studies have examined the influence of various human activities on nesting bald eagles (e.g., Grubb and King 1991, Grubb et al 1992, Parson 1994, Watson et al 1999, Steidl and Anthony 2000. Similarly, many studies have shown that human disturbances can cause nest site abandonment or reduced reproductive output by ospreys (e.g., Swenson 1979, Poole 1981, Levenson and Koplin 1984, Ewins 1997, Saurola 1997) and great blue herons (e.g., Forbes et al 1985, Parnell et al 1988, Carlson and McLean 1996, Vennesland 2000, Skagen et al 2001. However, other than for these 3 species, there is limited quantitative information on the effects of human activities on sticknesting birds.…”

Forest management and stick-nesting birds: New direction for mitigation in Ontario

Forest management operations (harvest, renewal, tending, road construction and use) may affect the occupancy or productivity of nest sites used by stick-nesting birds (eagles, ospreys, herons, hawks, owls, corvids) either by directly disrupting breeding activities, altering habitat suitability, or creating new access that may lead to subsequent disturbance of nest sites by other forest users. On public land in Ontario, potential effects are mitigated through an area-of-concern planning approach that involves placement of buffers around nests that restrict the timing of forest management operations, habitat alteration, and the construction of new roads. Early direction developed in the 1980s was based largely on expert opinion. The Ontario Ministry of Natural Resources (OMNR) has reviewed and revised this direction to incorporate new understanding of habitat requirements and the effects of forest management operations. Case studies are provided to show how published literature, directed studies, and the precautionary principle were used to revise direction for ospreys and great blue herons. For many species, this review led to a reduction in the size of buffers deemed necessary to mitigate the effects of forest management operations. Despite the increased use of scientific evidence, there is still uncertainty about the effects of forest management operations on stick-nesting birds and the effectiveness of proposed direction. OMNR is developing a monitoring plan to evaluate the effectiveness of revised direction as part of its cycle of adaptive policy development.Key words: buffers, stick-nesting birds, eagles, ospreys, herons, hawks, owls, disturbance, habitat alteration, access RÉSUMÉLes opérations d'aménagement forestier (coupe, régénération, entretien, construction et utilisation de chemin forestier) peuvent entraîner des effets sur l' occupation ou la productivité des sites de nidification utilisés par les oiseaux qui nichent en hauteur (aigles, balbuzards, hérons, faucons, hiboux, corvidés) soit en interrompant directement leurs activités d'accouplement, soit en modifiant la qualité de l'habitat ou encore en créant un nouvel accès qui pourrait entraîner une perturbation subséquente de leur site de nidification par d'autres utilisateurs du milieu forestier. Sur les terres publiques de l'Ontario, les effets potentiels sont atténués par une approche de planification des zones sensibles qui comporte la mise en place de zones tampons autour des nids et qui régit le calendrier des opérations d'aménagement forestier, la modification de l'habitat et la construction de nouveaux chemins. Les premières directives élaborées au début des années 1980 découlaient en grande partie de l'avis des experts. Le Ministère des Richesses naturelles de l'Ontario (MRNO) a révisé et reformulé ces directives pour y incorporer les nouvelles connaissances acquises sur les qualités de l'habitat et les effets des opérations d'aménagement forestier. Nous présentons des études de cas afin d'illustrer comment les textes publiés, les é...

“…Unlike sea turtles, many shorebird nests are on the surface where they are particularly vulnerable to predation (e.g., Parnell et al, 1988). Not only are eggs, chicks, and adults susceptible to predation, but predatory pressures (including by raccoons) can result in abandonment of a nesting colony and localized catastrophic breeding failure (e.g., Ellis et al, 2007;Kadlec, 1971;Rogers et al, 1996).…”

Predation critically threatens reproductive success of sea turtles and shorebirds at many of Florida's beaches. We examined the biological and bioeconomic results of predator management on two adjacent barrier islands, Cayo Costa and North Captiva, along Florida's west coast. Both islands suffered severe nesting losses due to predation and disturbance due to raccoons, while Cayo Costa also was impacted by a large population of feral swine. In 2006, our initial year of study, neither island received predator management and no least tern production occurred on either island, and sea turtle nest predation was 74% and 60%, respectively, for Cayo Costa and North Captiva. Predators were managed in 2007 on Cayo Costa while North Captiva served as an untreated reference island. North Captiva again had no least tern production and sea turtle nest predation was 84%. In contrast, Cayo Costa produced 31 least terns and sea turtle nest predation plummeted to 16%. Both islands received predator management in 2008 when Cayo Costa and North Captiva respectively produced 20 and 55 least terns and had 15% and 0% sea turtle nest predation. The entire costs for predator management by experts over the course of the study was $USD 39,636, while the returns in additional production of least tern young and hatchling sea turtles was valued over $USD 1.1 million for a resulting benefit-cost ratio of 27.8.Published by Elsevier B.V.
