MARC recordDiet and prey consumption rates of nesting boreal owls, Aegolius funereus / Jackson S. Whitman.
| Title: | Diet and prey consumption rates of nesting boreal owls, Aegolius funereus / Jackson S. Whitman. |
| Author(s): | Whitman, Jackson S. |
| Date: | 2009. |
| In: | Canadian Field-Naturalist. (2009.), Vol. 123(2) (2009) |
| Abstract: | Investigates dietary composition and prey consumption rates of nesting boreal owls (Aegolius funereus) between 2004-2006 using two methods. Determines dietary composition during nest visits by examining 1,882 fresh remains containing at least 11 mammalian and 15 avian species. Calculates consumption rates based on laboratory examination of seven prey detritus bricks following fledging, yielding 1,051 items of five different taxa. Results show that boreal owls are preying on mammals in proportion to their abundance. |
