Scientists Strive to Save Rodents Rare Red Tree Mice Put on Milk Diet High Death Rate Caused by Fast The Daily Californian March 18, 1936. Every effort to keep alive the last tree of 14 red tree mice was being made today by University scientists in the Museum for Vertebrate Zoology. The mice, brought to the campus two weeks ago from the Russian river, have gradually been dying off until only a few are left. Accord- ing to D. H. Johnson, technical assistant, restriction in captivity and incomplete diet have probably caused the high death rate. Found only in a humid coastal belt between the Russian river and the Columbia river, the mice are probably the only species in the world living in trees and having red fur. The attempt to raise the rodents is incidental to the real purpose of their capture, which was to obtain the rare mammal as museum speci- mens. As far as the scientist could learn, the rodents' only food is Douglas fir tree needles. The one remaining youngster of the mama and papa mice has finally learned to drink milk after many days of drought he suffered because of his youthful ignorance.
