Upon measurement, Morago reported the elk horns as four varas [] across... "These animals [elk] are called ''ciervos'' in order to differentiate them from the ordinary Spanish variety of deer, here called ''venados'', which also exist in abundance and of large size in the vicinity." Regarding pronghorn, Moraga reported: "In the said plains of San Bernardino (Santa Clara Valley)…there is another species of deer about the size of three-year-old sheep. They are similar in appearance to the deer, except they have short horns and also short legs like the sheep. They live in the plains where they go in herds of 100, 200, or more. They run all together over the plains so fast that they seem to fly…These animals are called ''berrendos'' and there are many of them also in the southern Missions wherever the country is level."

Highway 101, according to Craige Edgerton, recently retired executive director of the Silicon Valley Land Conservancy and local naturalist Michael Hundt. In 2019, a fifth herd of tule elk was documented by local naturalist Roger Castillo, likely having split from the Coyote Ridge herd and established itself in Silver Creek Valley around the closed Ranch Golf Club. The elk herds in eastern Santa Clara County are blocked from dispersal to the west by U.S. Highway 101, with environmentalists advocating re-purposing the Metcalf Road bridge at the Coyote Gap into a wildlife overcrossing.
