Nest site is in tree, often oak, juniper, or pine, usually well hidden among foliage. Data from the North American Breeding Bird Survey (BBS) indicate that Pinyon Jay numbers have ..... 43 Table 13. The question motivating this study came from habitat managers who repeatedly requested specific values of Pinyon Jay habitat covariates, e.g., “typical” canopy cover or tree diameter, to guide management of Pinyon Jay nesting habitat. Enemies: The pinyon jay may be something of a nest robber, but it also has been preyed upon itself occasionally. It is usually placed 3-20 feet above the ground in a tree. Destroying pinyon-juniper forests puts pinyon jays at risk. It is almost always found in flocks, sometimes up to a hundred or more individuals. Pinyon Jays usually nest in colonies. When pinyon seeds are abundant, the Pinyon Jay is one of the earliest-nesting passerines in North America. The pinyon jay is about 9-11 inches in length, and it has a wingspan of about 18 inches. A specialist on Pinyon Pine seeds, the Pinyon Jay rarely wanders far from this habitat during the breeding season. The pinyon jay, Gymnorhinus cyanocephalus, occurs throughout much of the western United States, and is a common bird of the pinyon-juniper forests of Utah.Pinyon jays are often found in loose flocks that consist of multiple breeding pairs and the offspring of those pairs from previous nesting seasons. Take Merlin with you in the field! It has a long, sharply pointed black bill; a short tail; a grayish-blue to blue body and a white chin. We have captured Pinyon Jays using walk-in traps and mist-nets, and we fitted them with tiny glue-on radio transmitters. The Pinyon Jay (Gymnorhinus cyanocephalus) is a jay between the North American Blue Jay and the Eurasian Jay in size. The pinyon jay population has shrunk by an estimated 85 percent since 1970, and another 50 percent of the remaining population is expected to be lost by 2036.

It also nests colonially, and the bulky platform nest is made of twigs and bark and lined with bark and hair. We addressed this challenge in studying the occurrence of Pinyon Jay (Gymnorhinus cyanocephalus) nest locations in four piñon-juniper woodland sites in New Mexico, USA. Pinyon Jay nest plots from unused plots at KAFB and WSMR, 2009-2011..... 41 Table 12. In Texas, where flocks are smaller, may nest as isolated pairs.

A Pinyon Jay is a fun bird to see while bird watching. Authors: John M. Marzluff. Pinyon jays did nest near (but not within) treatment polygons in 2018, suggesting that moving planned treatments relatively small distances or initially siting them to avoid traditional pinyon jay nesting areas could achieve fuels management goals while avoiding serious impacts to pinyon jay nesting colonies. In 2017, the Taos BLM Field Office requested that Natural Heritage New Mexico survey for breeding Pinyon Jays at the Rio Grande del Norte National Monument; 2017 surveys focused on North Guadalupe Mountain, the In addition, any new roads, parking areas or trailheads won't be allowed within 1,100 yards of any pinyon jay nesting colony sites. Within each flock, 2-4 females may nest at one time; each is attended by one male, but may mate with other males in flock as well.

Pinyon Jays have been known to nest in nearly every month of the year, in response to abundant green pinyon cones (fall), cached seeds (late winter), or insects (spring and summer, Ligon 1978, Balda 2002). Meanwhile, pinyon pines are especially susceptible to droughts associated with climate change. Young are fed insects, bird eggs and nestlings of other bird species.

Using generalized linear mixed models, we employed covariates describing woodland structure at several scales to discriminate nest from non-nest plots. The pinyon jay is one of the earliest nesting passerines in the United States. It is almost always found in flocks, sometimes up to a hundred or more individuals. ASU - Ask A Biologist.
