We used newer, larger-scale 2007 colour air photos to interpret habitat attributes and classify habitat quality of 14 Marbled Murrelet (Brachyramphus marmoratus) nest sites identified in 1992 (n = 2) and 1999 (n = 12) in Mussel Inlet on the Central Coast of British Columbia. Mussel Inlet is a fjordland environment atypical of other areas for which the air photo interpretation classification has been tested using nest sites (i.e., Haida Gwaii, Vancouver Island, and south coastal British Columbia). Nesting habitat described by 3-ha plots centred on the nest site was characterized in Mussel Inlet as having complex canopies with large trees in mid to low meso slope positions, and as such is comparable to that reported elsewhere in British Columbia. However, comparisons of the nest plot habitat attributes to those at 27 random plots also suggested that interpretations of murrelet habitat selectivity for Mussel Inlet differed from other coastal areas due to differences in characteristics and availability of forest structures. Overall in Mussel Inlet, more nest plots were classed as lower quality (i.e., 50% Low and Very Low) on air photos compared to other British Columbian studies (i.e., ~14% Low and Very Low). Although selectivity testing based on air photo habitat class was inconclusive, particularly for the High and Very High quality habitats for which limited habitat was available (~1 % of the study area), a trend was indicated for higher proportional use of Moderate and Low habitats and lower proportional use of Very Low habitats. We discuss limitations of the samples used for this study and issues in interpretation, resolution, and scale in applying the air photo methods in topographically complex, fjordland landscapes such as Mussel Inlet. Given these limitations and issues, we recommend use of aerial survey methods to confirm occurrence of nest platforms.

The Forest Practices Code guidebooks help forest resource managers plan, prescribe and implement sound forest practices that comply with the Forest Practices Code. This guidebook is designed to be a "fine filter" approach to addressing habitat requirements of critical wildlife, in addition to the "coarse filter" approach provided by the Biodiversity Guidebook and the Riparian Management Area Guidebook.
This book describes the foraging habits and capture rates of four species of bird-hunting falcons; Peregrine, Merlin, Gyrfalcon, and Prairie Falcon. Eight of the nine study areas were situated in western Canada in widely different habitats, and the observation periods intermittently included all seasons over 44 years, 1965-2008.
"Air photo interpretation (API) is widely used in British Columbia for assessing and mapping forest nesting habitat of the Marbled Murrelet (Brachyramphus marmoratus). For strategic land use planning in Haida Gwaii, the entire land base (approximately 1 million ha) has been mapped based on polygons assessed with API. The API method does not, however, detect microsite features in the forest canopy, especially the presence of mossy mats and other potential nest platforms, which are essential for murrelets to nest. This study was therefore undertaken to compare the API habitat quality classifications with those made by low-level helicopter surveys (aerial surveys), which focus on the canopy structure and the presence of potential nest platforms."--Document.
Current Ornithology publishes authoritative, up-to-date, scholarly reviews of topics selected from the full range of current research in avian biology. Topics cover the spectrum from the molecular level of organization to population biology and community ecology. The series seeks especially to review (1) fields in which an abundant recent literature will benefit from synthesis and organization, or (2) newly emerging fields that are gaining recognition as the result of recent discoveries or shifts in perspective, or (3) fields in which students of vertebrates may benefit from comparisons of birds with other classes. All chapters are invited, and authors are chosen for their leadership in the subjects under review.
