OK, Yeah, There’s Still A Bird Post-


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)


How About A Little Science On Tuesday?

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

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

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.

Your Weekly Birds: The Songs, The Cuteness … And A Bonus!


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)


It’s A Bird’s Life


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)


The “Tip-up Warbler”

Palm Warbler

Setophaga palmarum

Also Known As

  • Wagtail Warbler
  • Tip-up Warbler
  • Bijirita común (Spanish)
  • Reinita coronicastaña (Spanish)

About

The Palm Warbler is unusual among the Western Hemisphere’s wood-warbler family. While the majority of warblers are sexually dimorphic, with males noticeably brighter in the breeding season, the male and female Palm Warbler are nearly identical, and can be impossible to tell apart. Warblers, in general, spend a majority of their time in trees and shrubs, but the Palm Warbler is quite comfortable on the ground. Rather than hopping like their arboreal relatives, these birds take to walking or running. Like other warblers, the Palm Warbler often joins mixed-species flocks outside of the breeding season. However, though most warblers tend to flock up with other arboreal species, the Palm Warbler is just as likely to be found foraging with sparrows along hedgerows and in open weedy fields.

Palm Warblers share another habit more typical of ground-dwelling birds in that they continuously bob their tails. This behavior is also seen in other birds typical of open habitats, including the Spotted Sandpiper and Black Phoebe, where the rate of bobbing is thought to vary with the bird’s level of excitement, and thus plays a role in communication. In many ways, the Palm Warbler behaves more like a sparrow or pipit than a typical wood-warbler — even its monotonous trilled song is remarkably similar to that of a Dark-eyed Junco or Chipping Sparrow. Though perhaps an oddball among its own family, this unique bird has found a niche all its own, somewhere between a sparrow and a warbler. (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


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.
