PINYON
JAY
Gymnorhinus cyanocephalus
PASSERIFORMES
Crows and Jays (Corvidae)
Range
and Habitat
Resident from central Oregon and Montana southward to central Arizona,
New Mexico, and extreme northwestern Oklahoma. Preferred habitats include
ponderosa pines, pinyon-junipers, and forests of mixed pine and oaks.
SOUND:
"crauk-crauk", "kaa-eh"
Pinyon Jays store seeds in the fall to eat in the winter and
early spring. They have a very good memory and can hidden seeds even
under cover of snow. Mated pairs appear to coordinate their food caching
so that their cache locations
are known to each other.
They live in large flocks that may number up to 500 and may spend their
entire lives in the flock into which they are born.
Their scientific name, Gymnorhinus, which means “bare nostrils”,
refers to the fact that, unlike its close relatives, it does not have
feathers at the base of its bill. This allows them to probe deep into
pitch-covered pinecones to extract seeds without fouling the feathers
that cover the nostrils of other jays.
A group of jays has many collective nouns, including a "band",
"cast", "party", and "scold" of jays.
The Pinyon Jay has a fixed or limited range which encompasses regions
of the western and southwestern United States, where the birds choose
habitats along the foothills and lower mountain slopes. Ranging from
central Oregon, east to western South Dakota and south to Baja, California
and central New Mexico, the birds preferred habitat and feeding grounds
include pine forests, shrublands and even rural gardens.
Currently this species is under threat of habitat loss from deforestation
of pinon-juniper woodland which is the location for massive flock feedings.
Due to this, population trends for the Pinyon Jay have a present evaluation
level of Vulnerable.
