All About The Birds

Ollie has endeared himself to some house finches who come here to eat. He’s done this by chasing the squirrel off the feeder they prefer. He doesn’t realize he’s doing favors for the birds; he wants to play with the squirrel, especially zoomies. But, for 2 days in a row, I’ve watched house finches, in pairs, chase a squirrel back in Ollie’s direction by swooping the squirrel. They also are, so far, the only birds who don’t fly up away from this feeder when Ollie goes outside. Even the crows tend to fly into the trees until he comes back inside. So the house finches fascinate me this year. Anyway, here are these about more birds, and a bat, too.

The Yellow-winged Blackbird

Also Known As

Trile (Colloquial, Chile)
Alférez (Colloquial, Uruguay)
Varillero ala amarilla (Spanish)

About

The Yellow-winged Blackbird is a conspicuous species of the Southern Cone of South America, congregating in colonies in marshes during the breeding season, and forming larger flocks in wetlands, grasslands, and agricultural fields the rest of the year. These birds are also extremely vocal, giving a startling variety of calls, including sharp and percussive sounds, clear and musical whistles, and a range of other rattling, chirping, whining, whirring, and gargling vocalizations. Their song in particular makes use of virtuosic trills, robotic whistles, and mechanical whirring or buzzing sounds, coming across as half bird, half sci-fi robot. This iconic song is also the source of one of the Yellow-winged Blackbird’s nicknames, “trile,” and some authors propose it may also be the origin of the name of the country Chile! As if to make the most of their raucous acoustic capacity, the males of an entire colony will sometimes sing together in one big, cacophonous chorus.

In addition to nesting together in the same space, Yellow-winged Blackbirds also synchronize their nesting in time. Most of the females in a colony will lay within several days of each other. As a result, most of the nests in the colony will be on the same timeline, with eggs and nestlings developing at about the same time across the marsh. (snip)

Historic Oregon Bill Generating Conservation Funding Is Signed Into Law

Oregon will soon have a new, dedicated source of conservation funding to support the recovery of struggling bird and wildlife species across the state. House Bill 4134, dubbed 1.25% for Wildlife Bill, passed the Oregon State Senate in February and has now been signed into law by Governor Tina Kotek. American Bird Conservancy (ABC) strongly supported the 1.25% for Wildlife Bill, a proactive measure expected to raise up to $30 million annually for wildlife conservation in the state.

“This is monumental: Oregon has chosen to invest in its wildlife and its future with the passage of this historic law. Habitat restoration, recovery programs, and anti-poaching efforts are just a few of the programs that will be funded by this landmark legislation,” said Hardy Kern, ABC’s Director of Government Relations.

The Act will create a sustainable funding source dedicated to conserving imperiled species like the Marbled Murrelet, a seabird that nests in mature and old-growth forests in the state. Nest predation by jays and ravens contributes to the species’ declining population. Actions that could boost nesting success, such as campground cleanup efforts to reduce jay and raven numbers near sensitive nesting sites, are currently unfunded, but could benefit from the revenue generated by the newly signed law.

The Word

The Bird’s The Word:

Least Flycatcher

Empidonax minimus

Also Known As:

Chebecker
Mosquero Mínimo (Spanish)
Mosquerito Chebec (Spanish)
Papamoscas Chico (Spanish)

About

The Least Flycatcher is a small but fierce bird of North American forests, known for its fearlessness in confronting birds much larger than itself, including formidable foes like Blue Jays and even hawks. They often share habitat and compete with American Redstarts, a fly-catching warbler, which they exclude from the best habitat through repeated chases and attacks. Of course, Least Flycatchers defend their territories from their neighbors as well.

However, despite their intense territoriality, these flycatchers are widely known to form dense clusters of breeding territories, even in areas with plenty of suitable habitat. Interestingly, the males closest to the center of a cluster are the healthiest, and the first to find mates. Conversely, birds that don’t join a cluster usually do not mate at all that season. While other factors may contribute to this pattern, the main influence seems to be that it facilitates birds mating with their neighbors in addition to their social mate.

Least Flycatchers are socially monogamous, pairing with a single bird during the breeding season with whom they defend a territory and raise young. But these birds are also quite promiscuous. More often than not, the nest of a mated pair will have at least one nestling sired by another male. “Spreading the love” in this way benefits both males and females — females end up with more genetic diversity in their nests, while males don’t have all their eggs in one “basket,” in case a nest fails. This breeding system, where territories are clustered together, females seek matings outside of the pair, and paired males compete for each other’s mates, has been described as a “hidden lek.” In some ways, this system is quite similar to the communal display areas, or leks, where birds like Lesser Prairie-Chicken and Greater Sage-Grouse defend small arenas to display for females.

One big difference between a classic lek and the so-called “hidden lek” of Least Flycatchers is that both the male and female in a pair are looking to mate with other birds without their own mate knowing about it. Also, the displays are a bit less dramatic. Rather than elaborate plumages, dances, and bizarre methods of sound production, these drab males instead opt to sing the same monotonous two-note song several thousand times an hour.

Threats

Though fairly common in appropriate habitat, Least Flycatcher populations have been declining since the 1970s. There are now a little over half as many Least Flycatchers as there once were. As such, Partners in Flight lists them as a Common Bird in Steep Decline. More research is needed to better understand the causes of this decline, but factors affecting the structure and health of forests probably play an important role. (snip)

“Northern Emerald-Toucanet”

Also Known As: Tucanete Esmeralda (Spanish), Tucancillo Verde (Spanish)

Aptly named for its striking green plumage, the Northern Emerald-Toucanet is actually quite camouflaged in the leafy forests where it makes its home. With its tropical take on countershading — darker green on the back and wings, lighter yellow-green below — this bird beautifully matches the color palette of forest leaves, whether seen from above or from below. With its accents of chestnut, blue, and white, and a large black and yellow bill, this pigeon-sized bird is a true beauty.

Similar to other toucans, Northern Emerald-Toucanets eat mostly fruit, capitalizing on the wide diversity of fruit-bearing trees in the humid forests of their home in Central America. These birds mostly swallow their food whole, including some larger-seeded fruits, which they repeatedly regurgitate and swallow until the flesh is consumed. Whether by regurgitation or defecation, these birds spread the seeds of their food trees throughout the forest. Many tropical trees have evolved to bear fruit specifically for this purpose, taking advantage of birds’ wings to spread their seeds far and wide. In fact, the process of moving through the digestive tract of an animal actually helps the seeds of many of these trees to germinate. In effect, these toucanets, along with a cohort of other fruit-eating birds and mammals, are gardeners of their own food forests. (snip)

Bird Gallery

The Northern Emerald-Toucanet is indeed a beautiful, vibrant green, top and bottom, with the back a deeper, darker hue and the underparts lighter and slightly yellowish. The long tail is iridescent blue and green, with a rusty or chestnut tip matched by the vent feathers beneath the tail. The eight subspecies across its geographic range vary in the coloration of the throat, either blue or white, and the bill. In all subspecies, the lower mandible is black. The upper mandible has some black as well, but may be almost entirely yellow. Some subspecies also have a reddish to brown patch near the nostrils.

“Jewel Bird”

Replendent Quetzal

About

Considered sacred by several Mesoamerican civilizations, the Resplendent Quetzal remains culturally significant to this day. The Resplendent Quetzal likely inspired Quetzalcoatl, the “plumed serpent” god of Mesoamerica. Legend has it that Quetzalcoatl helped create Earth. Rulers and nobility wore headdresses made from this quetzal’s shining green feathers, which symbolically connected them to the god.

In some Mesoamerican cultures, it was considered a crime to kill a quetzal, so the plumes were procured by capturing the bird, plucking its long tail feathers, and setting it free. In several Mesoamerican languages, the term for quetzal can also mean “precious” or “sacred.”

These iridescent green tail feathers also symbolized spring plant growth to the Aztecs and Maya, who viewed the quetzal as the “god of the air” and as a symbol of goodness and light. The Maya also viewed the quetzal as a symbol of freedom (due to the difficulty of keeping them in captivity) and wealth and status, as its feathers were used as money. Even today, the currency of Guatemala is called the quetzal.

The Resplendent Quetzal is also the national bird of Guatemala, pictured on the country’s flag and coat of arms. It was thought to be the spirit guide of a Maya ruler and hero, Tecún Umán, who fought against the Spanish conquest. According to legend, Tecún Umán was killed as he fought the conquistador Pedro de Alvarado. As Tecún Umán lay dying, a quetzal flew down and landed on his chest, dipping its feathers in the hero’s blood. This is supposedly how the bird acquired its red breast and belly feathers.

This spectacular species belongs to the trogon family, a group of colorful, fruit-eating birds found in the Americas, Asia, and Africa. Other family members found in the Americas include the Golden-headed Quetzal, the Elegant Trogon, and Haiti’s national bird, the Hispaniolan Trogon.

Threats

Birds around the world are declining, and many of them, like the Resplendent Quetzal, are facing ever-increasing threats. Partners in Flight includes the Resplendent Quetzal on its Red Watch List as a species of high conservation concern, and also classifies it as a “Tipping Point” species — one that has lost more than 50 percent of its population within the past 50 years.

“Enigma Of The Pacific”

Marbled Murrelet

Brachyramphus marmoratus

About

The petite, quail-sized Marbled Murrelet has been called the “enigma of the Pacific.” So much about this stub-tailed seabird is unusual and remains poorly known. The bird’s range extends from Alaska to California; in northern treeless areas, it nests on the ground, but in the rainforests of the Pacific Northwest, it flies inland as far as 55 miles to nest high in trees. Its nesting habits remained one of North America’s great bird mysteries until 1974, when a tree surgeon working 147 feet up in a 200-foot-tall Douglas fir found an active nest. The only other bird in the alcid family that shares this nesting behavior is the murrelet’s close cousin, the Long-billed Murrelet, found in Asia.

Marbled Murrelet populations are in steady decline, due in part to the clearing of old-growth temperate rainforests, habitat shared with the imperiled Northern Spotted Owl. But nest predation by clever corvids like Steller’s Jays and Common Ravens can also adversely impact murrelets. These birds gather where people enjoying the Pacific Northwest’s forest leave garbage behind — the picnic areas and campsites more than 100 feet below nesting murrelets — making it all the more important to clean up and pack out what you bring in.

Threats

Seabirds are declining faster than any other bird group. The Marbled Murrelet faces many of the threats that endanger all seabirds, but the loss of its old-growth forest nesting habitat is unique among seabirds. Listed as Threatened under the Endangered Species Act in 1992, the Marbled Murrelet is also listed as a Yellow Alert Tipping Point species by Partners in Flight, a result of the loss of more than 50 percent of its population in the past 50 years.

“Virginia Partridge”

or “Virginia Quail.”

Snippet:

The Northern Bobwhite, also known as Virginia Quail or Virginia Partridge, is in the same family as the Montezuma and Scaled Quails, but the bobwhite is the only native quail species in the eastern United States. This delightfully round little quail is capable of strong, short bursts of flight — particularly when fleeing predators — though they prefer to walk or run, scuttling about under the dense, low cover of vegetation in grasslands, agricultural fields, and open forests.

The Northern Bobwhite is more often heard than seen, its namesake whistled bob-white! call sounding from the brushy undergrowth, where their dappled brown-and-white plumage provides excellent camouflage. But sometimes, especially when calling in spring, males will occupy highly visible locations, perching atop fenceposts and tree limbs.

A popular game bird, the Northern Bobwhite has a whopping 22 subspecies across its range, one of which — the Masked Bobwhite — is federally listed as Endangered. Its status as a game bird has made it one of the most well-studied birds in the world, and scientists have observed sharp declines, likely owing to multiple causes that include habitat loss and the increased use of pesticides.

Threats

Populations of Northern Bobwhite plunged between 1966 and 2019, resulting in an overall decline of 81 percent, according to the North American Breeding Bird Survey. Partners in Flight considers the Northern Bobwhite as a “Common Bird in Steep Decline.” For years, an explanation for such drastic declines has been elusive. However, most biologists agree that multiple causes are to blame. (snip-MORE on the page)
