“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.

Two From The Birds

They just keep on keepin’ on!

The Mountain Chickadee

Any season of the year, the Mountain Chickadee is a delight to encounter. In their breeding season, they form neighborhoods of adjacent territories in the conifer forests of western Canada and the U.S., which ring in the early spring dawn with dozens of cheerful whistled songs. In winter, groups of Mountain Chickadees are joined by other birds — nuthatches, woodpeckers, creepers, kinglets — to form large dispersed flocks that move together through the forest, following the chickadees’ namesake rallying call.

Mountain Chickadees are social birds, living in groups of up to three mated pairs and juveniles of the last breeding cycle for most of the year, only breaking off into territorial pairs for the breeding season. In fact, while we tend to think of the breeding season as the time when mates are chosen and territories are established, most of this actually occurs in the winter. This is when the social hierarchy is solidified between the individuals in a group, and come spring, the dominant birds will reliably take the best territories. While boundaries may shift somewhat, the same birds will usually hold the same territories year after year. Pair bonds are formed during the winter as well, and usually last for as long as both birds survive.

Mountain Chickadees are well-known for their caching behavior. To survive harsh mountain winters, these chickadees hide surplus food throughout their winter territories, a behavior known as “scatter hoarding.” A single chickadee may cache tens of thousands of food items — insects, conifer seeds, or goodies from bird feeders — over the course of a year. They may cache food any time they have extra, and may recover caches any time of the year, but spend the most time caching in the fall, and the most time eating from them in the winter. In fact, studies have shown that Mountain Chickadees living in harsher winter environments have better spatial memory and are more adept at remembering where they have cached food. Unsurprisingly, these birds also survive longer. (snip-MORE)

The Black-Billed Magpie

More than most, the Black-billed Magpie is a bird that inspires strong emotions in humans. A familiar species across much of the West, the Black-billed Magpie is intelligent, adaptable, and bold. For these attributes, they are both admired and loathed. While considered an annoyance or an inconvenience by some, they are also highly social and will occasionally leave “gifts” for humans who feed them.

Like many other intelligent and opportunistic corvids, magpies will take advantage of whatever resources they can. As such, the Black-billed Magpie is probably best known as a scavenger of garbage, carrion, and poorly guarded picnics. This has given these birds a bad reputation, with many regarding them as pests. A common folk belief is that magpies will wound cows to eat their flesh or drink their blood. Magpies will, in fact, stand on the backs of cows to probe and peck. However, the goal is typically not to eat the cow itself, but the parasites on the cow, such as ticks, that are doing just that. Cows are not the only beneficiaries of this behavior — magpies will eat ticks off of other large mammals, including bison, moose, elk, and deer.

The Black-billed Magpie holds a special place in mythology as well. Magpies are recognized as messengers in numerous Indigenous cultures of North America, sometimes to the aid of humans, sometimes to carry news to the Creator. One widespread story tells of how the magpie, for helping humans and birds alike, was given the honor of “wearing the rainbow” — a reference to the iridescent sheen on this bird’s wings and tail.

For Science! And For Species Protection & Diversity, Too

New study reveals that 1,300 new species have been added to the global mammal count

Jan 12, 2026 1:24 PM

According to a new study published in the Journal of Mammalogy, the number of living mammal species has increased by 25% since 2005 — meaning that more than 1,300 new species have been added to the scientific record.

Just a few mammals in that crowded class include new creatures like the mouse opossum (Marmosa chachapoya) of the Peruvian Andes, the olinguito (Bassaricyon neblina) of Ecuador, and the dwarf shrew (Crocidura stanleyi) of Ethiopia.

“Our recognition of 25% more mammal diversity now than 20 years ago indicates an overall improvement in our understanding of how global mammals interact with their environments,” Dr. Nathan Upham, lead researcher and Arizona State University professor, told A-Z Animals.

“Each species is genetically unique, not interbreeding with their close relatives, and thus presumably doing something unique on the landscape — specializing in different food or habitat type or location of activity,” he explained.

Upham’s research centered on a series of mathematical equations.

Since 2005, the Mammal Diversity Database has listed an additional 1,579 species.

Of those new species, 805 were newly described and 774 were “splits,” or offshoots, of what was originally thought to be a single species. 226 species were also merged after new evidence came to light.

In total, that means 1,353 species have been discovered since 2005, amounting to an average of 65 new mammal species being introduced to the scientific record every year.

In his interview with A-Z Animals, Upham emphasized that species are not evolving at a faster rate; they are simply becoming easier to find and identify.

“Next-generation DNA sequencing technologies have dramatically lowered the cost of obtaining DNA across the genomes from hundreds of individuals simultaneously,” Upham said.

Upham’s spotlight on mammalian research is supported by a larger, separate study published in Science Advances by John Wiens, a professor in the University of Arizona Department of Ecology and Evolutionary Biology.

Together with his fellow researchers — Xin Li, Ding Yang, and Liang Wang — Wiens estimated that 16,000 new species are discovered each year.

“These thousands of newly found species each year are not just microscopic organisms, but include insects, plants, fungi, and even hundreds of new vertebrates,” Wiens told the University of Arizona.

In 2025, Wiens also spearheaded research on the rate of species extinction and found that it lags significantly behind new species identification.

“Our good news is that this rate of new species discovery far outpaces the rate of species extinctions, which we calculated to about 10 per year,” Wiens said.

“Discovering new species is important because these species can’t be protected until they’re scientifically described,” he added. “Documentation is the first step in conservation – we can’t safeguard a species from extinction if we don’t know it exists.”

“Chickadee Warbler”

Golden-winged Warbler

About

Tiny, nimble, and sporting a bold black mask and “bib” under its bill, the Golden-winged Warbler might be mistaken for a Black-capped Chickadee at first glance. But it’s the long, thin bill and the splashes of vivid golden-yellow on its crown and wings that distinguish this long-distance migratory warbler.

Though they are denizens of shrubby, early successional habitats (areas that are in the early stages of regenerating following a disturbance, such as a fire or a clearcut) in the nesting season, Golden-winged Warblers and their recently fledged young relocate to nearby mature forests that provide adequate cover for fledglings from predators. The loss of quality brushy, young forest habitat across much of its breeding range has contributed to sharp declines in an already uncommon warbler.

Another threat comes from a close relative, the Blue-winged Warbler, which shares more than 99 percent of its genetic material with the Golden-winged Warbler. The two species regularly hybridize, and the once-uncommon Blue-winged Warbler has surged northward into the Golden-winged’s range. The Golden-winged Warbler has become much scarcer and is at risk of being genetically “swamped” by its more numerous and widespread relative where their ranges meet.

To gain a foothold and begin to recover from the loss of more than 60 percent of its population, the Golden-winged Warbler needs active habitat conservation throughout its annual life cycle, from the shrubby, early successional habitats where it nests to the open forests of Latin America and the Caribbean, where it spends its nonbreeding season.

Threats

Birds around the world are facing threats, and many species are declining. The Golden-winged Warbler has experienced a drop in its population of more than 60 percent, including a loss of nearly all of its population in the Appalachians. In addition to competition and hybridization with the Blue-winged Warbler, the Golden-winged Warbler faces challenges throughout its full annual cycle from habitat loss and degradation, and collisions.

“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)

“Lotus Eater”

Mississippi Kite

We get Mississippi Kites in late Spring; they’re about gone now. They give amazing air shows! Watching them makes a day better.-Ali

About

With pearlescent gray feathers and a sleek silhouette, the Mississippi Kite glides gracefully through the skies on wingbeats that manage to look effortless. While this medium-sized raptor with long, pointed wings and a squared-off tail may resemble a Peregrine Falcon in flight, the Mississippi Kite’s bouyant and easy flight can quickly distinguish it from the rapid, businesslike flight of the falcon. Its aerial acrobatics have earned the kite nicknames like “Hovering Kite.”

A long-distance migratory species, the Mississippi Kite breeds throughout the southern and central United States, making use of wooded areas in a range of settings — in large, low-lying forest tracts, windbreaks (stands of wind-resistant trees and shrubs) in prairies, and even in urban settings. Their habitat use and even their social behaviors vary throughout their range, with kites in the west being more likely to nest in colonies than their counterparts in the east.

Threats

The global Mississippi Kite population is increasing, and its range has expanded into parts of the Southwest since the mid-20th century. Even so, the cumulative impacts from threats like habitat degradation and loss, pesticide use, and collisions may make the Mississippi Kite more vulnerable across parts of its range.
