The Richmond density of one nest per km^ is greater than most other densities reported. A greater-than-average nesting density may be a result of nearby destruction of habitat with expanding development which forces the birds into a smaller area. On the other hand, the combination of open farmland and river edges and islands may provide ideal habitat for the Red-tailed Hawk. Bednarz and Dinsmore (1982

A greater-than-average nesting density may be a result of nearby destruction of habitat with expanding development which forces the birds into a smaller area. On the other hand, the combination of open farmland and river edges and islands may provide ideal habitat for the Red-tailed Hawk. Bednarz and Dinsmore (1982), on the basis of results reported by several authors, hypothesized that accessibility in terms of an open flight pathway to the nest is the overriding factor in suitable territories. The many locations at or near the edge of the Fraser River or on islands in the river provide this accessibility. The highest single concentration of nests within the study area prior to 1984 was in the southeast corner of Lulu Island and very near to the Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Ottawa Field-Naturalists' Club.
