A Field Sparrow sits on a slender branch among sunlit green leaves, facing right in warm golden light, its back to the viewer. Its soft gray breast, warm reddish crown, and delicate pink bill glow in the evening sun while the small bird balances lightly with its tail trailing behind, its head turned to its right shoulder so it is looking at the camera, clearly a lady with an attitude.

A Black-throated Sparrow perches on a smooth gray branch, body angled left so we see his chest; he is looking over his left shoulder. The small desert sparrow shows a pale gray face with bold black-and-white stripes and a sharply defined triangular black throat patch above a soft gray belly. Fresh green leaves frame the branch against a softly blurred background. The little bird is a fella that was in the mood.

A Song Sparrow perches on a lichen-dusted branch against a bright blue sky, its brown streaks and central chest spot clearly visible. Facing left with an upright stance and its back to the viewer, the sparrow shows layered feather patterns along its back and tail while pale green lichens decorate the branch beneath its feet. The bird is looking over its left shoulder at the camera, alert and composed. 
Don’t just stand there, let’s get to it.

A Savannah Sparrow stands atop a pale yellow post beside deep blue water, facing right, tummy and chest visible, with its tail extended behind it. Its finely streaked breast and yellow eyebrow catch the warm sunlight while the background fades into a smooth blue blur. Balanced neatly on the flat perch, the small sparrow on its tiny stage is framed by light and open space. It looks sharply to the left to strike a pose; there’s nothing to it.

A Blue Jay perches on a horizontal branch of a flowering dogwood, facing left and showing its back and long tail. The bird’s soft gray-blue back contrasts with bright blue, black, and white barred wings and tail feathers, while its pale face and small crest are visible in profile. Clusters of white dogwood blossoms and fresh green leaves surround the branch, and the background fades into a smooth, softly blurred gray-green.

A Blue Jay sits among a dense cluster of white cherry blossoms, chest to the camera, head facing left; its crest is raised. The bird’s pale gray -- nearly white -- chest and belly contrast with its blue crest, wings, and tail, while a black collar and dark bill mark the face. It is surrounded by white flowers and reddish new leaves, with the overcast yet bright sky softly glowing behind the flowering tree.

An American Crow perches on the horizontal bar of a silver metal gate, chest to the camera, head turned to the left in profile. The medium-sized bird is entirely black with slightly ruffled feathers and a stout dark bill, and a small reddish mark is visible near the corner of its beak. Two rounded metal gate posts frame the crow on either side, while the softly blurred background shows pale green vegetation.

A Mexican Jay perches on a tangle of pale, leafless branches, facing right, its front to the viewer and its head turned to the right. It appears to be sizing up the viewer and is likely to pass judgment soon. The medium-sized bird shows soft blue plumage on the head, wings, and tail, with a pale gray throat, chest, and belly. Its sturdy gray bill and dark eyes stand out against the powder-blue head. Sunlight highlights the bird’s smooth feathers while the background of dry branches and woodland is softly blurred.

Close-up of a Green Jay’s head and upper body in side profile, facing left, its colors in strong contrast to the pale gray background. The bird shows a glossy black head and throat bordered by bright cobalt-blue patches around the eye and cheek, with vivid lime-green feathers on the back and shoulder. His stout dark bill and dark eye shine in the sunlight. He would like to know what you think about his proposal.

Two White-necked Ravens fly to the left; they are close together, like military jets in a flight exhibition. The large dark birds show long broad wings with splayed wingtips, and each has a pale patch at the base of the neck that contrasts with the otherwise black plumage. They fly through a clear pale blue sky with no landscape or clouds visible.

A Black-crowned Night Heron rests at the edge of calm water, facing right in close side profile. The stocky bird has a smooth black crown and back, pale gray wings, and a creamy white face and chest. Its bright red eye stands out sharply against the pale head, and a stout dark bill points forward over the water. The heron sits low beside a small gravelly hard surface, with soft blue and green reflections and faint tree shapes mirrored in the water behind it.

A Black-winged Kite perches upright on a thin bare branch against a soft blue sky, its body facing left and head turned to look somewhat behind it; we see its head in profile. The small raptor shows pale gray and white plumage with bold black patches on the shoulders and wings, a short hooked black bill, and bright orange-red eyes. Its yellow feet grip the branch while its long gray wings and tail taper neatly behind, giving the bird a poised, alert look. Sunlight falls on the bird's wings, face, and feet; its breast and the back of its head are in shadow.

A Brown Thrasher perches on a slender diagonal branch, its body facing the camera, its head looking to the left of the photo. It's slightly floofed up. The bird shows warm rufous-brown upperparts and a pale buff chest boldly marked with dark teardrop-shaped spots. Its bright yellow eye stands out against the softly blurred green foliage in the background, while its long tail hangs below the branch.

The vulture is looking at us with his left eye.

Its long bare neck rises into a fluffy pale crown of feathers, with large brown eyes and long dark eyelashes on either side of its pinkish beak. The bird’s slightly tousled facial feathers and curious expression give it a comical look, while the softly blurred green landscape behind it keeps attention on the ostrich’s expressive face.

The slender bird gleams metallic emerald green, with darker wings and an extremely long narrow tail extending behind it. Its long, strongly curved black bill points forward as it sits upright among thin branches and small leaves, the bright sunlight highlighting the bird’s iridescent green plumage. What a shiny bird!
