Fig 4. Diet of individual bears by season.

Guard hairs for each sample (n = 40) were cut into 3 equal lengths. We assumed hair began growing June 1 and finished Oct 31. Each point depicts the diet between it and the previous x-value which was June 1 for the first segment of all samples. For hair samples that we believed came from the year the sample was collected, the last day of growth was the collection date. Observation date was calculated by dividing the difference between the beginning and end of hair growth into thirds. Grizzly bears detected in drainages with spawning salmon are shown in red symbols (n = 23). Green symbols indicate bears detected in drainages without spawning salmon (n = 17).
