Question: Mannan and Meslow (1984) studied bird foraging behaviour in a forest in Oregon. In a managed forest, 54% of the canopy volume was Douglas fir, 40% was ponderosa pine, 5% was grand fir, and 1% was western larch. They made 156 observations of foraging by red-breasted nuthatches; 70 observations (45% of the total) in Douglas fir, 79 (51%) in ponderosa pine, 3 (2%) in grand fir, and 4 (3%) in western larch.
The study conducted by Mannan and Meslow (1984) investigated bird foraging behavior in a forest located in Oregon. In this managed forest, the canopy volume consisted of 54% Douglas fir, 40% ponderosa pine, 5% grand fir, and 1% western larch. The researchers made a total of 156 observations of red-breasted nuthatches foraging in these different tree species. The observations were distributed as follows: 1. Douglas fir: 70 observations were made in this tree species, representing 45% of the total observed foraging. 2. Ponderosa pine: 79 observations were made in this tree species, making up 51% of the total observed foraging. 3. Grand fir: Only 3 observations were recorded in this tree species, accounting for 2% of the total observed foraging. 4. Western larch: 4 observations were made in this tree species, which represented 3% of the total observed foraging. From this data, it seems that red-breasted nuthatches in the studied forest preferred foraging in Douglas fir and ponderosa pine trees, as they constituted 96% of total foraging observations. However, it is important to take into account the proportion of each tree species in the canopy when interpreting these results.
