觀察細節
One banded adult feeding a juvenile. Info from BBL: ‘I have been notified by the Bird Banding Lab (see below), that you saw one of my color banded Clark's nutcrackers at Crater Lake! That is very exciting, and I appreciate you for reporting this bird. In 2016, as a PhD student, I was awarded a research grant by the Science and Learning Center at Crater Lake National Park. My research project studied the foraging behavior and spatial cognition in nutcrackers that frequented the areas along Rim Drive, where much human-food supplementation occurs. I then compared the foraging behavior to what I observed in nutcrackers that lived in several areas within the park far from Rim Drive. To conduct this study, I caught nutcrackers in walk-in traps and applied unique combinations of color bands to their legs so I could identify them again in the wild. I found that nutcrackers that lived far from the human-food supplemented areas along Rim Drive cached more food in comparison to those nutcrackers that were seen at Rim Drive. Due to the very small sample size and time scale during which this project was conducted, I have not yet been able to publish these results. I am happy to see one of our subjects is still alive 3 years later. I am also happy to answer any additional questions you might have about me, CLNU, or my research. Best, Kelsey McCune’
