Book excerpt: The Leach's Storm-petrel (Oceanodroma leucorhoa) population breeding on Bon Portage Island, Nova Scotia $(43\sp\circ28$'N, $65\sp\circ45$'W) was censused in 1997 and 1998 to estimate the population size. In 1997, the breeding population on the southern end of Bon Portage Island was estimated to be 41,680 pairs (at 95% CI $\pm$11,169). An additional 5699 breeding pairs (at 95% CI $\pm$2128) were estimated to be nesting on the northern end of Bon Portage Island in 1997. In 1998, the southern end population was estimated to be 57,603 breeding pairs (at 95% CI $\pm$12,434). Nettleship's (1976) sampling protocol for Leach's petrel was improved by increasing sample site, thereby improving confidence in the resultant estimate. Other improvements included limiting the time involved in sampling and the amount of disturbance caused by the researcher. Both the total number of Leach's petrel burrows and those occupied were contagiously dispersed within the confines of the suitable habitat on Bon Portage Island. The effect of human activity on the breeding Leach's petrel population on Bon Portage Island appears highly localized to areas of direct usage. (Abstract shortened by UMI.).

Available in PDF, EPUB and Kindle. Book excerpt: I mist-netted southbound migrating landbirds on Bon Portage Island, Nova Scotia, to determine the importance of the island in these birds' migration. I specifically asked: (a) are the numbers of migrants that come to Bon Portage in the fall related to wind direction? (b) can any species deposit fat on the island? and (c) does wind direction influence either the abundance or fat loads of individual species in the fall? I tested for a relationship between wind direction and the total capture rate of all migrants combined. I next tested whether individual species can deposit fat on the island. Finally, I tested if wind direction had an effect on either the capture rates or the fat reserves (determined by weights and fat scores) for species for which there were adequate data: Myrtle Warblers, Blackpoll Warblers, and Red-eyed Vireos. I conclude that most birds initially come to Bon Portage Island simply because of its location on the southern end of the province; however once there, some species, such as Myrtle Warblers, are nonetheless able to stay and deposit small amounts of fat.
