  • Bird of the Month: Western, Clark’s grebes

    By DeeDee DeLorenzo Western and Clark’s grebes are found throughout Arizona and are common breeders in the marshes along the Colorado River. Both species are about the size of a loon and have contrasting black and white plumage and relatively long, slightly curved necks. Until 1985, they were thought to be color phases of the same species — namely, the Western Grebe. There are several ways to identify each species. A breeding Western Grebe’s black cap extends below the eye, while the Clark’s Grebe’s cap stops above the eye. Another way to distinguish the two birds is by bill color. The Western’s bill is a drab greenish-yellow; the bill of the Clark’s is orange-yellow to bright yellow. A less obvious way to tell these two grebe species apart is by their overall body plumage. The back and sides of a Western Grebe are dark with little or no white mottling. The Clark’s Grebe will show some white on the sides and the back tends to be lighter. The Western makes a creaking, two-note call and sounds like a gate slowly opening then shutting: “ker-kreek.” The Clark’s Grebe makes a single syllable call: “k’rrree.” The gate opens, but doesn’t close. Behaviorally, the Western and Clark’s grebes have a lot in common. During the winter, they share the same lakes and ponds. Here they can be seen gliding on the water with

  • Bird of the Month: Ruddy Duck

    By Sharon Arnold Ruddy Ducks are widely dispersed in North America. These small, stiff-tailed ducks appear in large numbers on our lakes in the fall. Most have headed for more northern breeding territories by the end of March. Look for them in tight flocks diving for their food. In breeding plumage, the small, stocky males have bright blue, broad bills. Their bodies are reddish-brown with a black head and white cheek. They often swim with their tails held straight up. Females are brown year-round and their heads have a dark crown and a lighter cheek with a line through it. In winter, the male looks similar to the female. However, its cheek remains white. Their preferred food consists of aquatic plants and insect larvae and aquatic snails from lakebed ooze. The Ruddy Duck’s unique courtship display involves “bubbling.” Males thump their blue bills against their chests which produces small pond ripples and bubbles. The process often ends in an odd croak. Ruddy Ducks do not initiate courtship or acquire mates until they arrive on their nesting grounds. Ruddy Duck nests are well concealed in tall, emergent vegetation and are often floating platforms attached to cattails or bulrush. Sometimes, they cover nests by pulling vegetation from above and anchoring it to the nest. Most Ruddy Ducks only produce one brood, but in southern Arizona a longer nesting season can result in

  • Bird of the Month: January 2018

    By Russ Chappell If American Dippers are to be trusted — and, hey, they’re quite discerning — then Fain Park has a pond with quality water. Indeed, they’re quite picky and avoid even mildly polluted waters. A casual, transient, winter visitor, Dippers normally prefer fast-running, clear streams, where they feed on aquatic insect larvae like caddisflies, mayflies, beetles, bugs, and mosquitoes, as well as adult insects, worms, snails, fish eggs and small fish. They are, by and large, rarely seen on ponds or lakes. Also known as a water ouzel, American Dippers are stout and dusky grey with some brown on their heads, bright white eyelids and thick bills. They’re 5.5 to 8 inches in length, weigh 1.5 to 2.4 ounces, and have an extra eyelid called a “nictitating membrane” which helps them see underwater. They also have scales that block their nostrils when submerged. Permanent residents throughout their territories, which range from Alaska to Panama, some Dippers stay through winter when streams remain unfrozen. Others relocate to lower elevations and southward for the winter. They can tolerate cold water because of their low metabolic rate, their blood’s extra oxygen-carrying capacity, a thick layer of feathers, and the generous quantity of secreted oil, which keeps them warm while feeding underwater. When not foraging, you can catch them bobbing up and down on a rock or the shore. North America’s sole

  • Bird of the Month: Surf Scoter

    By Russ Chappell A juvenile Surf Scoter was recently spotted at Watson Lake along the shore northeast of the boat dock near Arizona 89. This surface-diving duck is classified as an accidental, winter visitor in Carl Tomoff’s “Birds of Prescott, Arizona Checklist.” “Surfers” migrate from Canadian and Alaskan breeding grounds to the coasts of North America during the winter feeding on mollusks, crustaceans, aquatic insects, small fish, and vegetation like aquatic weeds, wild celery, musk grass, and seeds. They usually feed in water less than 10 meters deep, near breaking waves, with flocks diving in a synchronicity fashion. Dive duration varies depending on prey density, season, and water depth. Adult male Surf Scoters weigh about 2.3 lbs and average 19 inches in length, with females 2 lbs and 17 inches. Males are a velvet black with white on their foreheads and napes, with thick bills that appear orange at a distance but have white, red, and yellow spots, with a black spot near the base. Females are brownish, becoming lighter towards their bellies. There are paler patches below their eyes and occasional white markings on their nape. The bills of females are black with shades of green or blue. Juveniles appear similar to females but are paler with whitish breasts and bellies. Displaying little vocalization, males make a gurgling call and a sharp puk-puk while courting. Females make a crow-like

  • Bird of the Month: White-faced Ibis

    By Doug Iverson The White-faced Ibis, a species seen mostly in migration in the Prescott area, is an unmistakable bird when sighted. It is a gregarious species you might first see in a flock of 15 or more birds as they circle over Willow or Watson lakes looking for suitable shoreline shallows. They may circle as if uncertain or wary before landing close to shore where they can be hidden from view by shoreline vegetation. Depending on location, an Ibis will feed on insects, earthworms, snails, newts, frogs, fish, crayfish, and other invertebrates it can spear with its long, decurved bill, often digging prey out of the mud in a marsh, on a shallow shoreline, in an irrigated field, or even in damp soil. They will change both feeding and breeding locations depending on the availability of suitable habitat in a given year. White-faced Ibis have a rich metallic luster, bronze-green feathers, long pinkish legs, pinkish lores, and white feathers on the face at the base of the bill. The White-faced Ibis can be distinguished from the Glossy Ibis only in breeding season when it has the border of white feathers on the facial skin behind the bill — they were formerly called White-faced Glossy Ibis — but this is not a local identification problem because we have no Glossy Ibis. The Ibis was a sacred bird of Ancient Egyptians,

  • Bird of the Month: Double-crested Cormorant

    By Russ Chappell Double-crested Cormorants are large, expert fishermen with a diet of fish supplemented with insects, crustaceans, and amphibians. They pursue underwater prey with powerful kicks of their webbed feet, and if they catch a crustacean, they strike it on the water until the legs break off, then flip it in the air, and catch it head first for easier swallowing. They have goose like bodies, long, loon-type necks, and thin, strongly curved bills, approximately the length of their heads. Adults are brown-black with yellow-orange facial skin, and the immature birds are browner with paler necks and breasts. They have aquamarine-colored eyes and bright blue inside their mouths. During breeding season, adults display double-crests of white or black scruffy feathers on their heads, thus the Double-crested Cormorant name. When not fishing, they rest on branches, rocks or the shore with their wings spread to dry, since their feathers contain less preen oil than other water fowl. This is a minor inconvenience that contributes to their underwater speed and maneuverability. Double-crested Cormorants usually reside near large bodies of water, however many form breeding colonies near small ponds and travel up to 40 miles to a quality feeding site. Listed as “uncommon transient and casual summer and winter visitors” in Professor Carl Tomoff’s “Birds of Prescott, Arizona,” they raise two broods a year with up to seven chicks per brood. A male attracts

    Why don’t you introduce yourself and the clubs you teach? This is my 25th year at Prescott Unified School District. In the past, I’ve mainly been in the behavioral field. I was a behavioral coach and ran a discipline room for many years. For the last several years, I’ve been the math interventionist for K-4 at Abia Judd Elementary School. I have some sports clubs, but also offer the Prescott Audubon Junior Nature Club as well as The Grand Canyon Club. These are enrichment clubs, after-school clubs really, offered once a week to 14 students at a time on a quarterly basis. It’s basically to introduce them to the Audubon as well as nature. We do a variety of things. I have outreach speakers who come. Mr. Wilson, the Great Horned Owl from the Heritage Park Zoological Sanctuary. We always have a docent from the Highlands Center, and, typically, someone from Audubon, of course. It’s so wonderful to have these speakers come. I have so much information I could give to them all on my own, but the kids love having speakers. We also do things like making bird feeders, dissecting owl pellets, and hiking and bouldering. Why are clubs about nature and the outdoors important? These children are the stewards of our future and the natural world. There’s so much stuff going on the in the world right now,

  • Bird of the Month: Grace’s Warbler

    By Russ Chappell The opportunity to spot one of Prescott’s least known yet common birds is rapidly coming to an end, as they will soon migrate to Mexico. Grace’s Warblers are one of the least studied American birds because they reside in forested areas, high in mature pine trees, where they forage for insects and spiders, raise their young, and rarely pose in open vegetation. They are, however, sometimes visible flying from the treetops while hovering and catching insects in mid-air. Grace’s Warblers are named for the sister of renowned ornithologist Elliott Couse, who first discovered the species here in Arizona in 1864. Couse is highly respected for his monumental literary works, especially “Key to North American Birds” (1872). Small song birds in the wood warbler family, Grace’s Warblers are approximately 4.7 inches in length with wingspans of 7.9 inches and weight 0.2 to 0.3 ounces. They’re striking birds featuring yellow chins, throats, and breasts; gray backs; white bellies; black streaks on the sides of their chests and flanks, short yellow eyebrows; yellow crescents under their eyes; two white wing bars; and white spots on their tails. The young are similar but paler and less streaked. According to the International Union for Conservation of Nature, the species is classified as “Least Concern.” Their nesting habits are largely unknown because their nests are so well hidden. The nests, themselves, are small

    How did you first get involved in nonprofits in the community? When my wife and I moved to Prescott in December of 2004, we discovered our home was surrounded by birds and wildlife. We thought it would be nice to feed the birds, so I visited Jay’s Bird Barn, where Eric Moore loaded me up with optics, books, seeds and birding information and invited me to the next Prescott Audubon Society meeting, so I guess Eric is ultimately responsible for my relationship with Audubon, and I thank him and blame him for that. As a pilot, I focused on avoiding birds, but I really never studied them. Halfway through that first Audubon meeting, I was planning how to graciously thank them for their hospitality and quietly slip out the door. The chapter’s IBA Coordinator, Karen O’Neil, was giving a presentation and her vocabulary and passion about birds were foreign to me, and I didn’t feel birders and I would be compatible. During a break, Eric introduced me to the chapter president, mentioning my background in computers, aviation and technology. The president asked if I’d be willing to operate their projector at the next meeting. I agreed and was thus committed to a second meeting. The president also mentioned the chapter had CD with a lot of data on it and wondered if I would review it and see if the

  • Bird of the Month: Northern Flicker

    By Maxine Tinney An incessant tapping sound along with a wika-wika-wika calling awakens my husband and I one early Spring morning. Going outside, we find the source of the drumming. A male Red-shafted Northern Flicker is gripping the side of one of our bird houses using his two toes pointing forward and two toes backward for support and his tail as a prop. He proceeds drilling on the surface of the wood roof with his robust, slightly down-curved bill to claim his territory, including intermittent calling of his wika-wika-wika love song to attract a mate. He is a large, light-brown woodpecker measuring about 12.5 inches with a handsome black-scalloped plumage, barred upperparts and spotted underparts, has a black bib, gray face, tan crown, red mustache malars, and would be a catch for any tan-malared female. As he flies away, he shows off his orange-red under-wing primaries and tail, white rump spot, rising and falling smoothly with interspersed periods of flapping and gliding. The Red-shafted Northern Flicker (Colaptes auratus cafer) is common to woodlands and forests of Yavapai County and the western United States. If you travel to the east and far north of the United States, you will find the Yellow-shafted Northern Flicker (Colaptes auratus auratus) with yellow under-wing primaries and tail, black mustache malars, and red crest on the nuchal nape. With luck and a keen eye, whilst visiting
