They prefer bulky seeds because of their large bills, and have an eating style of appreciating their food, rather than pecking like chickens and other doves, like the mourning dove. They also ingest small pebbles into their gizzards to aid food-processing. They often visit bird feeders and are fond of sunflower, milo, corn and safflower, but will also forage for berries.
They usually breed in woodland interiors, near feeding habitats like grain fields or desert cactus communities. During the winter white-winged doves are present throughout most of their breeding range, but some individuals wander widely across the continent.
Males choose the general nesting area and gather building materials, but the female selects a nesting site and builds the nest, usually on a branch or shaded crotch of a tree. A flimsy bowl about four inches across is constructed of twigs mixed with weeds, grasses or moss, and occasionally lined with leaves, bark, feathers or pine needles.
There are two broods per season of one or two creamy white or buffcolored eggs, around one inch in width and length. Incubation is 14-20 days, nesting time 13-18 days, and hatchlings are born helpless, eyes closed, with long off-white down.
If predators approach the nest, a white-winged dove may fake a broken wing as a distraction, or in other circumstances fly into a brushy area. When startled near houses they sometimes fly into windows, so making sure your windows are bird-safe is a nice touch.
This species rates an eight out of 20 on the Continental Concern Score, and is not on the 2014 State of the Birds Watch List.
This beautiful little bird can appear dark until its metallic-green back and shimmering purple rump capture the rays of the sun! A small bird, it averages slightly over four and a half inches in length, with a 10.6-inch wingspan and weighs half an ounce. Common in our area during spring and summer, they migrate to Mexico and Central America for the winter.
They routinely forage for insects over our lakes and ponds in groups of over a hundred, intermingling with other swifts and swallows, but they are easy to identify by white patches on the sides of their hindquarters and cheeks. Viewing them at a distance with binoculars makes following their flight easier since they can reach speeds of up to 28 miles per hour, around the cruising speed of a peregrine falcon! Similar to other cavity dwellers, they attract more parasites than species nesting in the open, thus they sunbathe and preen frequently, providing easier viewing and photographing as they perch on power lines and dead trees.
Breeding in open evergreen and deciduous woodlands, they prefer areas with dead trees featuring woodpecker holes or other cavities. Male and female build the nest, which can take up to 20 days. Constructed with grass, twigs, rootlets and feathers, the cup-shaped nest is up to three inches across, depending the cavity or nesting-box size.
There are one to two broods per season, each consisting of four to six white eggs, less than an inch in length and width. Incubation is around 14 days, with a nesting period of about 24 days. Hatchlings are born naked, eyes closed and with scarce patches of down on their backs, crowns, and scapulars.
Common throughout the West, this species is rated nine out of 20 on the Continental Concern Score, and is not on the 2016 State of North America's Birds Watch List.
This is a great time of the year to add this beautiful little bird to your list as it brings a smile to your face. Happy birding!
Deep blue, rusty and white, males are more colorful than the gray-brown, blue-shaded females. They are small and stocky, with straight bills and fairly short tails, measuring six to seven inches in length, with average twelve-inch wingspans and weighing about an ounce.
A social species, they form flocks of up to a hundred, sometimes joining with mountain bluebirds, American robins and yellow-rumped warblers as they forage for insects or berries, and vocalize their quiet, chortling calls. They can also be attracted to a partially wooded yard by putting up nest boxes equipped with predator shielding.
Western bluebirds may have a gentle look, but when territory battles occur, one male may attack the other’s legs, dragging him to the ground and aggressively pecking at him. Residing in open woodlands and at the edges of woods, this small thrush is a cavity dweller, nesting in tree cavities or nest boxes and often socializing in small flocks.
The female does most of the nest construction over a two-week period, gathering grasses, straw, pine needles, moss, other plant fibers and fur to build and line the nest in an irregular shape.
There are up to three broods per season, consisting of two to eight pale blue or white eggs measuring less than an inch in length and width. Incubation times range from twelve to 17 days, with a nesting period of 18 to 25 days. The young hatch naked with pink skin, light gray down and eyes closed.
Rated nine out of twenty on the Continental Concern Score, the Western bluebird is not on the 2016 State of North America's Birds Watch List.
If you are feeling blue, a trip to one of our local wooded areas may be just what the doctor ordered, because this beautiful little bird will certainly cheer you up!

These casual, transient winter visitors normally prefer clear, fast-running streams, where they feed on aquatic insect larvae like caddis flies, mayflies, beetles, bugs and mosquitoes, as well as adult insects, worms, snails, fish roe and small fish. They are rarely seen on ponds or lakes.
Also known as the water ouzel, the American Dipper is stout and dusky grey with some brown on the head, bright white eyelids and a thick bill, 5.5-8” in length and weighing 1.5-2.4 ounces. It has a nictating membrane, like an extra eyelid, which helps it see underwater, as well as scales to block its nostrils when submerged.
Permanent residents in a territory ranging from Alaska to Panama, some dippers stay through the winter where streams remain unfrozen. Others relocate to lower elevations and southward for wintering.
To help them tolerate cold water they have a relatively low metabolic rate, extra oxygen-carrying capacity in their blood, thick feathers and generous quantities of secreted oil, which keeps them warm when feeding underwater. When they’re not foraging you can catch them bobbing up and down on a rock or the shore.
The dipper is North America’s only aquatic songbird, its loud song consisting of high whistles and trills, “peee peee pijur pijur.” Both genders sing year-round. They defend the territory along the streams they frequent, and while feeding underwater may fall prey to bull or Dolly Varden trout. Unlike most songbirds they go through total molts as ducks do, rendering them flightless by late summer.
They construct globe-shaped nests with side entrances, on ledges or banks near the water, behind waterfalls or under manmade structures. Normally the female incubates 2-4 white eggs, which hatch in 15-17 days. The young grow into fledglings 20-25 days later.
This unique bird may still be hanging out at Fain Park, and perhaps you can add it to your bird book!
Approximately the size of mallards, Gadwalls have relatively square heads with sharp foreheads, bills that are more delicate than the mallard's, and in flight their necks are noticeably smaller and wings slimmer. They average 20 inches in length, weigh between one to two and three-quarter pounds, and have 33-inch wingspans.
These dabbling ducks feed on aquatic vegetation such as algae, grasses, rushes, sedges, pondweed, widgeon grass and water milfoil, including leaves, stems, roots, and seeds. They also consume snails, midges, water beetles and other invertebrates, especially during the breeding season. Gadwall also routinely steal food from surfacing diving ducks and coots!
Mating begins in late fall, and breeding is primarily in the Great Plains and prairies. During winter they reside on reservoirs, ponds, water wetlands, parks, sewage ponds or muddy inlets where there is aquatic vegetation.
They nest on islands within marshes, providing some protection from predators like foxes, weasels, mink, coyotes and badgers, but winged predators are still a threat. The female scrapes out a cup-shaped depression about a foot across and three inches deep, then uses her body as a mold as she adds twigs and leaves, finally insulating the nest with her own down feathers.
There is one brood per season consisting of seven to twelve eggs, which are laid one per day, and about one and a half inches by two inches in size. They incubate in 24 to 27 days. The chicks are able to leave the nest in one or two days.
Gadwall are not considered threatened, although they are the number three most-hunted duck in America.
March is a good time to visit our local lakes and add this unique duck to your personal birding list!
During migration long V-formations may be seen, however more geese are foregoing travel, because increased urban development is creating more parks and lawns that attract this species. They are also often heard flying, by day or night, with their honking calls that distinguish them from other species of geese or swans.
Canada geese are large water birds with long black necks, brown backs, tan chests, distinctive white cheeks and chin straps, and wide, flat bills. They can measure from 30 to 44 inches in length, have wingspans exceeding five feet, and weigh up to 20 pounds.
They feed by dabbling in the water or grazing at fields and large lawns. In spring and summer, they feed on grasses and sedges, including skunk cabbage leaves, and during fall and winter they rely on berries and seeds, specially enjoying blueberries.
The female constructs the family nest on ground in an elevated area, near water and with unobstructed views. The large cup-shaped nest receives a layer of her personal down and body feathers after the second egg is laid, and she does all incubation while her mate stands guard.
There is one brood per season consisting of two to eight cream-colored eggs, slightly larger than two by three inches. Incubation is within 28 days, with total nesting time as long as 50 days. Born with yellow down and eyes open, the young leave the nest in a couple of days, able to walk, swim, feed and dive, and prior to leaving feed on their yolk sacs.
The young often remain with their parents for their first year, and as summer fades the families become more social, congregating in large flocks as food becomes more scarce and migration time approaches.
Their total North American population in 2015 was between 4.2 million and over 5.6 million, and although 2.6 million are harvested by hunters each year, the species is not considered threatened.
