  The Ecology and Life History of Seed Caching Corvids
It appears that pinyon jays are converging on a distant relative the nutcracker in many characteristics, thus diverging from their close relatives the western scrub-jay and Mexican jay.
Pinyon jays are an exception, but they cache at such a rapid rate it is almost impossible to keep track of their cache sites.
Nutcrackers and pinyon jays which have morphological, and physiological adaptations for this behavior and are also most dependent on their cached seeds for winter survival and reproduction, performed significantly better than scrub jays.

 Mexican Spotted Owls and Fire - Literature Review
Mexican spotted owls typically nest and roost in structurally-complex, diverse forests with a variety of age- and/or size-classes, a component of large trees, often with many snags and down logs and relatively high basal areas and canopy closures (Ganey et al.
Mexican spotted owls generally nest in trees, although in the northern part of their range (southern Utah and Colorado) they often nest in caves or cliff ledges in canyons, and seem to prefer shady habitat with steep cliffs and rocky terrain (Willey 1998; Rinkevich et al.
Mexican spotted owls appear to be influenced more by the total prey biomass available than by the abundance of any particular species, with the possible exception of a potential positive association with deer mouse abundance in one geographic area.

 Pinus cembroides: Mexican Pinyon
A native North American tree, Mexican Pinyon is usually found 20 to 30 feet tall with a spread of 15 to 20 feet, although it may sometimes be larger.
It forms a compact, conical silhouette, producing a rounded canopy with age, and the lower branches are maintained on the tree, providing dense cover to the ground unless shaded-out by other growth.
Mexican Pinyon should be grown in full sun on well-drained soil, tolerating dry, poor, alkaline soils but not wet soils.

Measurements: Mexican Pinyon is a small, often shruby tree between 16 and 20 feet in height and 1 foot in diameter.
Notes: Mexican Pinyon is the chief source of Pinyon Nuts in Mexico, but is too rare in the United States to be a commercial crop.
It is separated from Mexican Pinyon (Pinus cembroides) by a thinner seed shell and an earlier shedding of the sheath of the needle bundles.

 Pinyon-Juniper Habitat
In Arizona, Pinyon Jays are permanent residents of pinyon-juniper woodlands and lower ponderosa pine forests in the northern and central part of the state (Balda and Bateman 1971), ranging east to Natanes Plateau, west to the Hualapai Indian Reservation, south possibly to Prescott area, and north to Mount Trumbull (Phillips and others 1964).
Pinyon Jays are nonmigratory but may exhibit irregular nomadic movements of hundreds of miles outside normal range during fall and winter when pine seed crops are poor (Balda and Bateman 1971, Phillips and others 1964, Westcott 1964).
Breeding is apparently triggered by abundant pinyon pine seeds which are harvested in fall and early winter and cached in breeding areas for use during late winter and early spring.

Pinyon jays live in flocks of 50 to 500 birds, and it has been estimated that during a substantial seed year in New Mexico, about 4.5 million seeds were cached by a single flock (46).
Gonadal activity of pinyon jays, for example, is increased before the breeding season by the combined effect of photoperiod, the appearance of cones, and a diet of seeds (46).
Pinyon is preferred for fuelwood since it has a higher heat value than any of its associates except the oaks and burns with a pleasing and distinctive aroma.

 Definition of pine nuts
In North America the main species are three of the pinyon pines, Colorado Pinyon (Pinus edulis), Single-leaf Pinyon (Pinus monophylla) and Mexican Pinyon (Pinus cembroides).
The other eight pinyon species are used to a small extent, as are Gray Pine (Pinus sabineana), Torrey Pine (Pinus torreyana) and Sugar Pine (Pinus lambertiana).
In the US, bad land use practices have led to the destruction of millions of hectares of productive pinyon pine woods by conversion to grazing lands, and in China, destructive harvesting techniques (breaking off whole branches to harvest the cones) and cutting of the trees for timber have led to losses in production capacity.

Pinyon jays are also seldom seen in ones and twos but in fairly good-sized flocks (30-50), where scrubs are almost never in flocks, even small ones.
Pinyons have more of a short wailing-type call, or perhaps more accurately, a wavering call, and sometimes a two-note call, where scrubs pretty much sound like a barking shriek.
