Osteophagy in wild giant pandas
摘要
Documented over the course of several years of scat sampling, we report on two different incidents of wild giant panda osteophagy in Sichuan Province, China. To confirm that the dense, white, fecal pellets were bone and from pandas, we sent samples to a mineralogy lab for analysis and extracted DNA. This analysis both confirmed our suspicion of osteophagy, and one sample yielded enough DNA to confirm the depositing species as giant panda. Though rare and consisting of less than 1% of collected scat samples, we posit that this behavior may constitute an important source of micronutrients for wild giant pandas.
