Some individuals have been observed collecting and consuming dead birds as sources of fat and protein. Thousands of trips are made during July and August to collect vegetation for winter.

In 1973, within the Pleistocene deposits in central Alaska, preserved specimens of collared pika were found along with some dung pellets; the Yukon territory also contained some... Wikipedia →
