Stellars Jay ( Cyanocitta stelleri )

The Stellars Jay ( Cyanocitta stelleri ) is a common character found in the forests of the western half of the United States. The bird is an opportunistic omnivore and closely related to the Blue Jay. The Stellars Jay has a black crested head and a vibrant blue body which is commonly about between eleven and twelve inches long. This bird has a lot of variations depending on location.

The Stellars Jay is commonly, mistakenly, called a “Blue Jay” in the Pacific Northwest. The Stellar, however, is a distinct species from the Blue Jay ( Cyanocitta cristata ). The major differentiating characteristic is the Blue Jay does not have a crest.

This bird commonly feeds upon seeds, nuts and acorns. Speaking from first hand information, they also love unsalted peanuts. The will also eat insects and other small invertebrates, including mammals. They are also known to raid other birds nests and can be very aggressive with other birds.

Stellars Jay breed in monogamous pairs and a clutch of eggs is typically 3 – 5 in number. Both parents are active is feeding the young.

Distribution

The Stellar’s Jay is a common bird located primarily in pine-oak woodlands and coniferous forests. The dark blue and black coloring of the species helps aid in camouflage in the shadows of the forest.

The species is fairly bold and aggressive in its behavior and it is quite common to encounter them around campgrounds and picnic areas.

This animal is found across most of the western states. The bird is known to cross breed with the Blue Jay when their ranges overlap.

The range of this bird is as far north as Alaska and to the south in Nicaragua. The Eastern boundary in the United States for this bird is Colorado and New Mexico.

Field Guide Description

“Crested; dark blue and black overall. Some races, including nominate from coast to northern Rockies are darker backed; have blueish streaks on forehead. Central and southern Rockies race, C.s. macrolopha, have long crest, paler back, white streaks on forehead, white mark over eye; largest race, carlottae, resident of Queen Charlotte Island off British Columbia, is almost entirely black above. Where ranges overlap in the eastern Rockies, Stellar’s Jay occasionally hybridizes with Blue Jay. Calls include a series of shack or shooka notes and other calls suggestive of Red-tailed Hawks. Range: Common in pine-oak woodlands and coniferous forests. Bold and aggressive; often scavenges at campgrounds and picnic areas. Casual winter visitor of lower elevations of the Great Basin, southern California and southwestern deserts.”

Mojave Poppy ( Eschscholzia glyptosperma )

Eschscholzia glyptosperma, commonly known as the desert gold poppy or desert poppy, is a species of flowering plant in the Papaveraceae family. This annual herb is native to the southwestern United States and northern Mexico, thriving in arid and semi-arid environments. This report aims to provide a comprehensive overview of the morphology, habitat, ecology, and uses of Eschscholzia glyptosperma.

Taxonomy and Nomenclature

  • Kingdom: Plantae
  • Clade: Angiosperms
  • Clade: Eudicots
  • Order: Ranunculales
  • Family: Papaveraceae
  • Genus: Eschscholzia
  • Species: E. glyptosperma

Morphology

Eschscholzia glyptosperma is characterized by the following features:

  • Roots: The plant has a taproot system that allows it to access deep water sources, which is crucial for survival in arid environments.
  • Stems: Stems are typically slender, erect, and can range from a few centimeters to about 30 centimeters in height.
  • Leaves: The leaves are finely divided and bluish-green, arranged in a basal rosette. They are pinnately divided into narrow, linear segments.
  • Flowers: The flowers are bright yellow to orange with four petals, each petal often having a distinct darker spot at the base. Flowers are about 2 to 5 centimeters in diameter and are borne on long peduncles.
  • Fruits: The fruit is a slender capsule, known as a silique, which contains numerous small, reticulated seeds.

Habitat and Distribution

Eschscholzia glyptosperma is adapted to desert and semi-desert habitats, typically found in sandy or gravelly soils. Its distribution includes:

  • Geographic Range: It is native to the southwestern United States, including Arizona, California, Nevada, and Utah, as well as northern Mexico.
  • Elevation: The plant can be found at elevations ranging from sea level up to 2,000 meters.
  • Climate: It thrives in regions with hot, dry summers and mild, wet winters, which is typical of desert climates.

Ecology

Eschscholzia glyptosperma plays a significant role in its ecosystem:

  • Pollination: The flowers attract a variety of pollinators, including bees, butterflies, and other insects, which are crucial for its reproduction.
  • Adaptations: The plant has several adaptations to survive in harsh desert conditions, such as a deep taproot system for accessing water and seeds that can remain dormant during unfavorable conditions.

Reproduction and Life Cycle

Eschscholzia glyptosperma is an annual plant, completing its life cycle within a single growing season. Key stages include:

  • Germination: Seeds germinate in the winter or early spring following rains.
  • Growth: The plant grows rapidly, forming a basal rosette of leaves and then producing flower stems.
  • Flowering: Flowering occurs from spring to early summer, depending on rainfall and temperature.
  • Seed Production: After pollination, the plant produces fruits that release seeds, which can remain viable in the soil seed bank until conditions are favorable for germination.

Conservation and Uses

  • Conservation Status: Eschscholzia glyptosperma is not currently listed as threatened or endangered. However, habitat destruction and climate change could impact its populations.
  • Uses: While not widely used in traditional medicine or agriculture, the plant is valued for its aesthetic appeal in wildflower gardens and for its role in supporting pollinators.

Eschscholzia glyptosperma is a resilient and ecologically important species adapted to the challenging conditions of desert environments. Its striking flowers and role in supporting pollinators make it a valuable component of its native habitats. Conservation efforts should focus on preserving its natural habitats to ensure its continued survival.

Western Wallflower (Erysimum capitatium)

A member of the mustard family, the Western Wallflower ( Erysimum capitatium ) is a brightly colored yellow flower which is quite common across the western United States, including Arizona, Utah and Nevada.. In European countries, the wallflower earned its name from a habit of growing on… you guess it, walls. More specifically stone, masonry or wooden fences. The name was transposed to the American species despite the fact the plants have no preference for walls.
