Nashville Warbler

Leiothlypis ruficapilla

Also Known As

Chipe Cabeza Gris (Spanish)

The Nashville Warbler is a lively songbird with elegant, understated plumage and a special fondness for sunny forests, brushy undergrowth, and juicy caterpillars. It is also one of several birds in the Western Hemisphere with a rather misleading name. This bird is only in the southeastern United States for a few weeks during migration on its way between the northern forests where it breeds and its wintering grounds in Mexico, Central America, and the California coast. The species was first documented in Tennessee, and the “Nashville” name stuck, although it only stops over in the area during migration.

The Latin name is also rather misleading to anyone watching this bird in the field — the species epithet ruficapilla refers to a small patch of reddish feathers on the bird’s crown, usually invisible among the gray feathers of the rest of the head. Like the Ruby-crowned Kinglet, Orange-crowned Warbler, and Yellow-rumped Warbler (scientific species name coronata, for the rarely seen yellow crown), this name may be mystifying to beginning birders, but it might also provide an avenue into the secret social life of the bird.

The ability to hide and reveal this bright, contrasting color patch allows these birds to produce a striking visual signal, which they use to communicate agitation and excitement, particularly in aggressive interactions between males at close range. The closely related Lucy’s and Virginia’s Warblers also have hidden reddish crowns, apparently used in similar contexts. In fact, colorful hidden crown patches have also evolved in distantly related species, like the Western Kingbird, suggesting they may play important roles in these birds’ lives. However, birds are rarely seen actually raising their crowns, and our understanding of their social use is only rudimentary.

Nashville Warblers are quite social. Once the young of the year are independent from their parents, these warblers begin to form large foraging flocks, numbering up to 100 birds. On their nonbreeding grounds, these birds are often at the center of equally large flocks with dozens of species, their persistent contact calls allowing other birds — and birders — to locate them in the forest canopy. In fact, Nashville Warblers may be a “nuclear species,” facilitating the formation of these large and diverse flocks with help from another energetic northern migrant, the Blue-gray Gnatcatcher. Typically, nuclear species are resident birds, not migrants. But when this warbler-gnatcatcher pair comes to town, they bring the party. (snip-MORE)

Snuffleupagus, a newly described species, is an adorable little predator

The seahorse cousin is named for its ‘uncanny’ resemblance to the Sesame Street character

Sheena Goodyear · CBC Radio · Posted: May 21, 2026 4:01 PM CDT | Last Updated: May 21

Solenostomus snuffleupagus, a newly described species of fish, is named after the beloved Sesame Street character, Mr. Snuffleupagus. (David Harasti)

Scientist David Harasti never had any doubt what he would name the tiny orange creature he first spotted on a diving expedition in Papua New Guinea in 2003.

But it would take another two decades for Harasti and his colleague Graham Short to find the elusive fish again, study it, and officially designate it a new species.

Meet Solenostomus snuffleupagus, namedafter the beloved Sesame Street character, Mr. Snuffleupagus.

“Snuffy for short,” Short, an ichthyologist at the California Academy of Sciences and the Australian Museum, told As It Happens host Nil Kӧksal. “The resemblance was quite uncanny.”

Short and Harasti have now written a new paper, published in the journal Fish Biology, describing S. snuffleupagus as a new species of ghost pipefish that makes its home along coral reefs, and disguises itself as red algae.

‘The awesome power of natural selection’

The fish has quite a few things in common with its namesake — mainly its orange-brown colouring, the long filaments that look like shaggy hair, and its elephant-like snout.

Milton Love, a marine biologist at the University of California’s Marine Science Institute in Santa Barbara, Calif., says the fish’s muppet-like appearance demonstrates “the awesome power of natural selection.”

“Clearly, all of the morphological features that we find endearing are of some value to the animal,” Love, who was not involved in the research, said in email.

“Or, and here is another hypothesis, Gaia created this fish after having one too many of those rum drinks that come with those little umbrellas.”

But its similarity to Snuffleupagus goes deeper than meets the eye.

It’s also extremely elusive, much like Mr. Snuffleupagus, who, in his early appearances on Sesame Street, was only ever seen by Big Bird, leading the other characters to mistakenly suspect he was imaginary.

Harasti and Short tried for years to spot a snuffy fish again after that first 2003 sighting to no avail.

Their luck changed in 2021 when some scuba diver buddies started seeing the little creatures on the Great Barrier Reef and got in touch. The scientists headed to Australia to see for themselves, and on their second dive, they found the fish.

“It’s an understatement to say that we screamed under water,” Short said. “We high-fived, gave each other a hug, and we were just so excited.”

An itty-bitty carnivore

In order to describe the fish and confirm it as a previously undocumented species, the scientists looked at CT scans of specimens first collected in 1993 during exhibition to far north of Queensland, Australia, in the Torres Strait.

Short says they were collected alongside several hundred other fish specimens and tucked away until he and his colleague came looking. But even back then, he says ichthyologist Helen Larson, who was part of the expedition, suspected it was a new species.

S. snuffleupagus, like other ghost pipefish, is a cousin of the seahorse.

Using iNaturalist, the citizen science platform, the scientists confirmed sightings of it in Tonga, Papua New Guinea and New Caledonia, suggesting distribution across the southwestern Pacific.

And while it may look like Big Bird’s beloved bestie, there are a few significant differences between S. snuffleupagus the fish and Snuffleupagus the muppet.

While Snuffleupagus is famously big — bigger even than Big Bird — S. snuffleupagus is roughly four to five centimetres long, about the size of an airpod.

And while Snuffleupagus would never harm a fly, S. snuffleupagus is a natural-born killer.

“They look adorable, very cute. They’re very delicate and slow moving in the water. And it’s been assumed that they only eat small crustaceans like small shrimp,” Short said.

Not so, he says. The CT scans found tiny fish skeletons in the specimens’ stomachs.

“Every fish has a role, and they are either eating or being eaten. It turns out, ghost pipe fish and in particular, snuffy … they’re just like other fish,” Short said. “They’re predators.”

Short says the widespread interest in S. snuffleupagus has been a delight, and he hopes it won’t be the last fish he brings attention to.

He and his colleague already have their eyes on another species of ghost pipe fish that is known to divers around the Pacific, but hasn’t been formally described.

If it works out, they plan to name it after another muppet, but Short wouldn’t say which one.

“Not yet, because I need approval,” he said.

Red-naped Sapsucker

Sphyrapicus nuchalis

Néʼézhiin (Diné / Navajo)

Also Known As

Chupasavia Nuquirroja (Spanish)
Carpintero Nuca Roja (Spanish)

About

The Red-naped Sapsucker is one of four species in the genus Sphyrapicus, the sapsuckers, which are a distinctive group of North American woodpeckers with a peculiar and unique foraging strategy. The sapsuckers are accurately named in that they do, in fact, drink sap, but not by sucking. Rather, these industrious birds create rows of small openings in the bark of specific trees to allow the sweet, nutritious sap to flow, much like a syrup maker tapping a maple tree. They then drink the sap directly from these wells, lapping it up with their specialized feathery tongues. Sapsuckers maintain these openings or “wells” throughout the breeding season, regularly expanding existing holes and opening new ones to take advantage of changes in sugar flow through the season. Their sign on trees is conspicuous: Neat grids of shallow holes that create rings around the trunks of thin-barked trees such as aspen, willow, alder, birch, lodgepole pine, and young Douglas-fir.

In creating these wells, Red-naped Sapsuckers also open an irresistible opportunity for other animals with a taste for sweets. Many birds, especially warblers and hummingbirds, are drawn to sapsucker wells. Researchers have also reported a range of mammals visiting wells, including chipmunks, squirrels, mice, deer, and even bears. Insects feed at these wells too, especially butterflies, moths, flies, wasps, and ants. In turn, the insect activity can attract additional birds that prey on insects, such as flycatchers.

Mourning Warbler

Geothlypis philadelphia

Also Known As

Reinita Enlutada (Spanish)
Chipe Llorón (Spanish)

About

Though relatively common over much of its range, the Mourning Warbler is secretive and notoriously hard to observe. These birds mostly stay close to the ground in dense thickets and brush where they forage and nest. Outside of the breeding season, Mourning Warblers are also fairly quiet and can easily go unnoticed. As a result, very little is known of this bird’s life history outside of the breeding season. In fact, there are sizable gaps in our understanding of its breeding biology as well — for instance, no researchers have documented the courtship behavior of this species.

However, one thing we do know is that these birds are fairly particular about their habitat requirements. Mourning Warblers are reliant on thick, brushy second-growth forest, the result of big ecological disturbances, such as fire or major storms, that kill numerous trees and open up gaps in the canopy. Following such a disturbance, habitat becomes acceptable after about two or three years. After another seven or eight years, the forest will have grown back enough that Mourning Warblers will no longer use it. This means that breeding areas for this species are constantly shifting, as one forest regrows and a new opening is (hopefully) created elsewhere. Sometimes referred to as a “fugitive species,” Mourning Warbler populations are frequently “on the run,” fleeing the regenerating forest and searching for another suitable opening.

Fortunately, these birds are not terribly picky about exactly what kind of disturbance creates this ideal habitat. Drought, disease, insect outbreaks, and especially fire are natural disturbances that this species probably relied on historically. In the current day, large forest fires are far less common, but for the Mourning Warblers, human activities seem to work just as well. These birds are commonly found in old clearcuts, abandoned agricultural areas, along logging roads, and even mining and oil well sites. While these heavily disturbed areas do not benefit most species, the Mourning Warbler makes it work. (snip-see MORE here)

Yellow-breasted Chat

Icteria virens

Also Known As

Buscabreña (Spanish)
Reinita Grande (Spanish)
Chipe Parlanchín (Spanish)
Chipe Arriero (Spanish)

About

At first glance, the Yellow-breasted Chat seems to be a mishmash of many bird families: its larger size and stout bill resemble a Scarlet Tanager’s, while its skulking habits and complex vocalizations seem more like those of a thrasher or mockingbird. Taxonomically, this bird was considered an unusual wood warbler in the family Parulidae. However, in 2017, the American Ornithologists Union gave this bird its own family — Icteriidae — based on its unique physical and genetic features. It is considered to be related to the blackbirds and meadowlarks of the Western Hemisphere.

Among birders, the Yellow-breasted Chat is best-known for two features of its behavior: its habit of staying hidden at most times within the thickest vegetation available, and its loud, wild, weird song and flight display. In 1953, ornithologist Arthur Cleveland Bent described the Chat’s song as a “medley of strange sounds, musical and otherwise, catcalls, whistles, and various bird notes coming from points now here, now there in the bushes” — sounds which would “betray the presence of this furtive and elusive clown among birds.” The song is indeed a strange and wonderful mix of cackles, clucks, whistles, and hoots. Only males are known to sing, and they do so from deep inside the densest cover. A male chat may sometimes sound as if he’s laughing at the frustrated birders trying to locate him. (snip-MORE)

Three-wattled Bellbird

Procnias tricarunculatus

Also Known As

Campanero Tricarunculado (Spanish)
Pájaro Campana Centroamericano (Spanish)

About

The Three-wattled Bellbird, like other Central and South American bellbirds in the Cotinga family, is a natural history paradox. Breeding males perch on exposed branches and sing one of the loudest songs of any bird, impossible to ignore and audible from more than half a mile away. However, despite this extremely conspicuous breeding season behavior, females and nonbreeding males are notoriously difficult to observe, foraging in the higher levels of the canopy and remaining remarkably silent. As a result, this species has been subject to fascinating and in-depth studies of its song and courtship behavior, but some of the most basic aspects of its natural history are unknown. For instance, only two nests have been recorded, one in 1975 and one in 2012, and no eggs or young have been documented.

But biologists have learned a great deal from studying the Three-wattled Bellbird’s song. The bellbirds belong to a group of perching birds known as the suboscines, which also includes tyrant flycatchers like the Western Kingbird and antbirds, such as the Marsh Antwren. While the “true” songbirds (or oscines) are famous for their song-learning abilities, suboscine songs are classically considered to be completely innate, with no learning taking place. However, the Three-wattled Bellbird shares an important feature with birds that learn their songs: dialects. Birds from Nicaragua sound noticeably different from Costa Rican birds in the Cordillera de Talamanca and the Cordillera de Tilarán, which each host populations with distinct songs. (snip-MORE)

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.

Eastern Warbling Vireo

Vireo gilvus

Also Known As

Vireo Gorjeador Oriental (Spanish)
Vireo Cantor (Spanish)

About

The Eastern Warbling Vireo is a quintessential species of spring and summer across much of eastern North America. This rather drab bird is often hard to spot, hidden up high among the leaves of tall deciduous trees, but its buoyant, easygoing song is hard to miss. One of the most persistent singers through summer, this vireo’s song is considered by many ornithologists and naturalists to be among the most beautiful in its range. Males do most of the singing, but females sing as well — an unusual trait among songbirds in temperate regions. Even more unusual, these birds will even sing while sitting on their nests!

Unfortunately for the vireos, Brown-headed Cowbirds seem to cue in on this species’ habit of singing from the nest. Cowbirds are “brood parasites,” laying their own eggs in the nests of other species, often resulting in the death of some or all of the host’s young. Female cowbirds are quite crafty, even using the movements of parent birds to determine the location of a nest; the more often a parent uses the same paths to and from the nest, the more likely cowbirds are to find it. However, Eastern Warbling Vireos are remarkably efficient at removing cowbird eggs, often puncturing the offending eggs with their bills before discarding them. Studies of this behavior showed that these vireos seem to recognize cowbird eggs by differences in the pattern of speckles on the shell — and get rid of them 90-100 percent of the time!

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)

Anna’s Hummingbird

Calypte anna

Colibrí Cabeza Roja (Spanish)

Anna's Hummingbird. Photo by Nick Athana.

About

The Anna’s Hummingbird is a characteristic and charismatic species of coastal Central, Southern, and Baja California, although this species has expanded its range northward along the Pacific Coast and eastward into the Desert Southwest. Like the Rufous Hummingbird, Anna’s is well known for its aggressive territorial behavior. Males fiercely defend feeding areas, where they chase away other male hummingbirds and even large insects such as bumblebees and hawk moths that try to feed there.

Although the Anna’s Hummingbird readily feeds from non-native plants, wild plants are still crucial to these birds — and the birds are just as critical to these native plants. Anna’s Hummingbirds are important pollinators of the chaparral flora of coastal California. Many of these plants flower in the winter months, coinciding with California’s wet season. To take advantage of this boon of nectar, Anna’s Hummingbirds in coastal California breed in what is the nonbreeding season for most North American species, nesting as early as mid-December. After the rains end, many hummingbirds will move up into the mountains to take advantage of blooms at higher elevations.

The Anna’s Hummingbird is a highly vocal species, especially for a hummingbird. Males sing a complex, scratchy-sounding song while perched and during their high-flying courtship spectacles. The male performs this diving display by first ascending to 100 feet or higher, then swooping toward the ground. At the bottom of his dive, he will be moving at about 60 miles per hour, just overhead of a female (or intruding male). At the last minute, he banks upward and flares his tail, causing his modified tail feathers to produce an explosive, high-pitched chirp. The gravitational force (“G-force”) caused by this maneuver would cause a human pilot to lose consciousness, but these little hummingbirds do it again and again, up to about 40 times back to back, when trying to impress a female. He also orients his dives to maximize the reflectance of his beautiful gorget — the gem-like patch of tiny iridescent purple-pink feathers on his throat. According to researchers Christopher Clark and Stephen Russell, from the perspective of a female, he looks like a “tiny, glowing magenta comet” plummeting towards her. (Snip-More on the page.

Emerald Tanager

Tangara florida

About

The Emerald Tanager is truly a gem of the forest, roaming through the canopy in search of fruiting trees in the humid montane forests of Central and northern South America. Although primarily a fruit-eater, this species is also adept at hunting insects and other invertebrates on tree branches, deftly manipulating mosses with its bill in search of prey. This behavior sets it apart from other tanager species it often flocks with, but outside of the Emerald Tanager’s range, other specialized tanager species may fill this niche.

The Emerald Tanager’s relationship with moss extends beyond its foraging habits. Though their breeding biology is largely undescribed in peer-reviewed literature, the nests that have been observed have either been made of moss entirely or thoroughly covered in it. This, of course, provides good camouflage on the mossy branches where these tanagers build their nests. (Snip; MORE, and hear the Emerald Tanager)
