difference between king rail and clapper rail

By that same evening, she had succeeded in stealing the sole remaining male (#443): From 1723 to 1843 that first evening they clappered [grunted] in duet 12 times and were seen copulating twice. Prominent chestnut-brown patch on wing is … But even they can get up pretty far into Clapper speed if they feel particularly motivated. California or San Francisco Bay Clapper Rail, Western Rail (Rallus longirostris obsoletus - Ridgway, 1874) Sometimes lumped together with the King Rail (Rallus elegans)Range: USA: Central California, with … They were observing two color-banded pairs of “Light-footed” Clapper Rails in California. But do you know the difference between a boxcar, a tank car and a gondola? This secretive bird lives most of its life concealed in dense vegetation. It’s not quite clear what motivates this call, but in both species it varies from a grunt to a squeak, and there do not appear to be any significant differences between the two species’ versions. Their taxonomic status long has been unclear due to their overall similarity and the fact that in eastern North America and Cuba, they hybridize. Clapper rails are closely related to all members of the genus Rallus but are geographically closest to the king rail. King Rail and chick in Illinois cc-by Andy Reago. Scattered populations have also been found along the West Coast, but the species is rare and localized in the West. Two days later, his mate (#421) began giving the “Kek-burr” call. You will pass your mother’s mitochondrial DNA to your children if you are female, and it will not pass at all if you are male. In 2014, the species was split into three: Clapper Rail; Ridgway's Rail of California, Arizona, and Nevada; and Mangrove Rail … These would be as follows (no English names proposed): So when might we see the AOU or other bodies deliberate this information? Excited birds may give many rapid “Keks” before the burr; in some situations, the burr is given separately. That would require all of the female hybrids to return to their mothers’ breeding grounds. The deeper flanges on locomotives with hi-rail wheels, however, may contact the track ties on low profile 2-rail … American coot. Virginia rail. These would be as follows (no English names proposed): So when might we see the AOU or other bodies deliberate this information? #birds, Jamaican Tody #jamaica #jamaicantody #birdsofinsta, Vermilion Flycatcher, Orange County, California #v, A very nice young White-crowned Sparrow at Normans, Red-winged Blackbird, Queens, New York #singing #b, Sora, Jamaica Bay Wildlife Refuge, Queens, New Yor. Save my name, email, and website in this browser for the next time I comment. Mitochondrial DNA is used in genetic studies because of its higher mutation rate, making it more valuable when looking for changes. Yellow-breasted Chat, Jamaica Bay Wildlife Refuge, Jamaican Lizard-Cuckoo, February 2020. Each of the females, once alone, eventually kek-burred when #443 was with the other one, and #443 responded every time by returning to the calling female, often quickly. Furthermore, King and Clapper Rails have been known to hybridize in brackish marshes where their ranges meet, spawning the dreaded “Cling Rails” — birds presumably intermediate in all respects, and not safely identified in the field, even when you can see them — which is not very often, for these ghosts of the cattails. However, the Clapper Rails show a definite preference for salt water marshes and the King Rails typically frequent fresh-water habitats. I just learned about recent research into the King/Clapper Rail complex: a 2012 Ph.D. dissertation by James Maley that not only found a solid genetic distinction between King and Clapper Rails (further demonstrated by this recent paper), but also found that West Coast “Clapper Rails” are part of a distinct lineage that also includes the tenuirostris “King Rails” of central Mexico. The CA delta region … Feeds at low tide on mudflats or hidden in salt marsh vegetation. King rails inhabit both freshwater and brackish marshes, while Clapper rails reside in tidal salt marshes (Meanley, 1985). Steve, However, I agree with Sibley’s basic point: an extended listen to a bird should provide, at least, a good strong clue to its identification. White-crowned Sparrow, Forest Park, Queens. That’s the original, time-honored and respected definition. James has reams of next-generation nuclear DNA sequencing data that shows hybridization dynamics at a fine scale. You probably know the difference between a sedan, an SUV and a pickup truck. nuclear DNA of classic genetics. King and Clapper rails coexist along a salinity gradient within marshes of the Atlantic and Gulf coasts of the United States. of nearby clades, produce viable young, and no one would know because they are only looking at the mitochondrial DNA. I’m assuming this one is safely called a King, since it was recorded just outside Columbus, Ohio: It’s clear that fast Kings overlap with slow Clappers (or is it that excited Kings overlap with bored Clappers?). Without the aid of a full-time mate, #421 abandoned her nest. Fascinating news (particularly identifying the hybrid zone on such a fine scale, and how salt is such a big obstacle to interbreeding) AND discussion. The main differences between Suburban Rail and Rapid Transit Rail Networks is the services that they provide. A clattering cackle in the salt marsh is often our first clue to the presence of this big rail. It remains locally common near the Atlantic and Gulf coasts, where it is not especially shy, often stalking about at the marsh edge in full view of observers. True, there are definable differences in clades. Clapper Rail Rallus longirostris, a bird of mainly coastal marshes, was split into three species, and King Rail Rallus elegans of the eastern U.S. was split into two. Perhaps tenuirostris of Central Mexico is proposed as a full species, instead of being lumped with the endangered Pacific and Baja populations? A chicken-sized marsh bird, the largest of our rails. California King rails are protected by the state of California, and perhaps due to that there is no rail hunting allowed in that state's NW delta marshes or flooded ricefields. Caribbean birds cluster with North American Clapper Rails. If you’ve got recordings, I’d love to hear them. It definitely used to be, but the perils of taxonomy-by-mtDNA are well-known now, and splitting species (and getting papers published) based only on mtDNA is a dying practice, IMO. Ridgway's rail. Mated pairs may perform extended, unsynchronized grunt duets, one starting slightly after the other, in one of nature’s least aesthetically pleasing romantic gestures. Thanks David for the excellent article summarizing my research on this complex! This is the vocalization that Sibley refers to as “a raucous squawk like a startled chicken”. In his doctoral dissertation — Ecological Speciation of King Rails (Rallus elegans) and Clapper Rails (Rallus longirostris) — for Louisiana State University, James Maley uses new genetic analyses and other data to identify three major groups within the Clapper-King complex: Maley then goes on to examine the hybrid zone between Clapper and King rails in Louisiana, finding that the hybrid zone is very narrow (about 4 kilometers, or 2.5 miles) and appears to depend on the presence of brackish marsh; where saltmarsh and freshwater marsh were immediately adjacent due to human manipulations, he found that birds did not interbreed. It’s typically heard for a fairly brief period out of the year, and given only rarely after the singer is paired. This sparrow-sized bird also prefers a habitat along the coastline in the same regions as the other rails. The Black Rail is the smallest member of the rail family. But identifying a group of birds as a “species” implies that the group is reproductively isolated from other groups. High quantities of salt can be deadly to birds (and many other living things), so rails living in saltwater environments have glands in their heads that excrete extra salt to maintain an internal balance conducive to life. Gray legs, feet. See the recent discussion on BirdForum for a little more info. Welcome to 10,000 Birds, the world’s favorite birding blog! Most of the time, the presence of one of these rails is announced solely by their loud, unmusical calls, leaving us to identify them solely by voice. The Clapper Rail is a large rail that is primarily found in salt marshes of the Eastern United States. Genetic studies on bird populations are almost always done on mitochondrial DNA. The birds’ mitochondrial DNA shows that, despite rails’ propensity for long-distance travel, the freshwater and saltwater populations are not two ends of a spectrum but rather maintain their distinctiveness despite the occurrence of hybridization in brackish environments. The large Clapper Rail is abundant in saltwater marshes and mangrove swamps from the U.S. East Coast to Central America and the Caribbean. (I assume here that specimens were obtained on home territories). In both proposals, we’d end up with 3 species of large rail in North America: King, “eastern” Clapper, and “western” Clapper. Common gallinule. The Clapper Rail is usually hidden in dense cover, but sometimes we see it … According to Sibley, eastern Clapper Rails “kek” at about 4-5 notes per second, while Kings are slower, usually 2 notes per second. In the case presented here, a female rail could be fooling around with males 2 Recognize regional differences that likely exist in vital rates, and other characteristics of rail and snipe populations ... Wilson’s snipe, sora, clapper rail, king rail, and Virginia rail These five species are … This site uses Akismet to reduce spam. Again the Clapper is the faster bird, and again I’ve found there to be more overlap between the species than reported in Sibley: Clappers appear to average 4-6 notes per second, while Kings clock in at 3-5 notes per second. But some recent work by James Maley and others is shedding more light on these secretive and fascinating birds. Any loud noise may set off a Grunt Series, and one grunting rail often sets off another. Females of both species give nearly identical “Kek-burr” calls, and I do not know of any way to separate the species by this call. Our Bird B is much more subtle than that, and while its orange-ish breast is rather more vibrant than … We witnessed #443 respond to kek-burring 11 times in 36.1 h of observations over 4 days. … King Rails are associated with freshwater and brackish marshes, while Clapper Rails … Male Kings and male Clappers “sing” with the same notes — the key to identifying them is to listen to the speed of their calls. Clapper Rail of the grayish U.S. Atlantic Coast subspecies crepitans in New Jersey by Corey Finger. As intimated in the article, we also suggest splitting R. e. tenuirostris from the southwest North American group. Clapper Rail: Large, noisy marsh bird, gray or brown upperparts, vertical white-barred flanks and belly, buff or rust-brown breast. King Rails occur widely in eastern North America, in eastern and central Mexico, and in Cuba. David J. Ringer is exploring the world one bird at a time. King Rail: Large rail with long, orange-based bill. Do the arguments in Maley’s thesis make sense to you? California’s three subspecies of Rallus longirostris become subspecies of Rallus obsoletus , which is given the English name Ridgway’s Rail. I haven’t read this study, and appreciate that nuclear DNA was also used, but in other studies supporting the epidemic of split-itis, it is not. The Clapper Rail is usually hidden in dense cover, but sometimes we see it stalking boldly along the muddy edge of the … For female rails, it must be quite an aphrodisiac, because it’s the primary way that males attract mates in early spring. Thanks everyone. I realize you’re discussing the issue of mtDNA as a sole marker for doing taxonomy a bit more broadly, but it is not an issue with this particular project. The need for cubbyholes for all these forms is why there are subspecies in the first place. • You can find rails: Find Virginia Rail, Sora, King Rail, Clapper Rail, Yellow Rail, and Black Rail You can find rails: Find Virginia Rail, Sora, King Rail, Clapper Rail, Yellow Rail, and Black Rail. I found some very excited Clappers reaching 5 notes per second, but an extended listen to most birds will find them averaging between 3 and 4 notes per second in the fastest parts of their series. His fascination with birds and nature began at the age of four or five, and he now works full time in conservation. Meanwhile, this recording at the Macaulay Library may represent the hoot of King Rail, but the bird making the sound was not seen, so it’s not even certain that the sound was made by a rail. Clapper rail. During one exchange he traveled the 190 m to the calling female within 18 min of the onset of kek-burring. Your mitochondrial DNA is completely from your mother, in perpetuity. What do you think? The photo above, one of mine, shows a Clapper Rail in Louisiana. One of those is the one we've been calling the California clapper rail. In eastern North America, birders think of King Rails as richly colored birds of freshwater marshes, while Clapper Rails are considered drabber birds of saltmarshes. It isn’t always possible, but today we’ll talk about when and how it can be done. Maley has a forthcoming paper in The Condor (Mitochondrial and Next-Generation Sequence Data Used To Infer Phylogenetic Relationships and Species Limits in the Clapper/King Rail Complex) that should provide the published evidence needed for taxonomic bodies to act, or at least open the discussion. Brown and red-brown mottled upperparts. […] Individuals may give faster or slower calls depending on mood, but such departures are usually brief. This is no way to define a new species. Bill is long, slightly decurved. Yellow rail. Although mitochondrial DNA does replicate as new mitochondria are produced, no sex is involved. Also, king rails … Other rails, gallinules and coots. Long, consistent bouts of typical calls can be reliably identified. Be sure to browse our extensive galleries, species accounts, and book and product reviews. If you can shed any light on the mysterious Macaulay recording from Florida, or on the hooting calls of rails in general, please let me know. Kings, meanwhile, seem to average between 2 and 3 notes per second. A clade comprising Clapper Rails of California, Arizona, and northwest Mexico plus King Rails of the highlands of central Mexico. What English names would you propose if the complex is split into four or five new species? There are very few recordings of this sound, but you can hear the hoot of a Clapper Rail here. Also, your statement that “Genetic studies on bird populations are almost always done on mitochondrial DNA” is not really true anymore. The clapper rail is killed most often, with about 23,000 bagged in 2009, followed by sora (12,500), Virginia (500) and king (less than 50) rails. In freshwater rails, this gland is smaller, and the birds do not fare well in saltier environments. Also, if both sexes are interbreeding with other clades, the two mtDNA lineages will be spread throughout both species. King Rails (Rallus elegans) and Clapper Rails (Rallus longirostris) are large, secretive waterbirds whose ranges overlap in brackish marshes along the Atlantic and Gulf Coasts. I wanted to point out that this work was done with Robb Brumfield (my adviser). Thus, it seems there’s a good case not only for keeping King and Clapper Rail separate, but further splitting Clapper Rail into 3 or 4 species. The two largest rails in the United States are so similar in appearance and vocalizations that they have at times been considered a single species. When another male appeared on the fourth day, #443 returned to #442, #421 settled in with the new arrival making use of the same nest), and kek-burring ceased. They have nothing at all to do with the Follow him on Twitter at, Best Bird of the Weekend (Third of April 2013), © 2019 10,000 Birds // All rights reserved. By … All subspecies, except the Northern Clapper Rail (R. l. crepitans), are non-migratory (Eddleman and Conway 1994). You can’t show rep[roductive isolation by looking at a product that only comes from mothers, any more than you can define a household income by only looking at the salary of one of the adults living there. And what are the conservation implications of elevating the endangered Pacific populations to full species status? Flight is low and fluttering over short distances. The Clapper Rail was found along the Atlantic, Pacific, and Gulf coastlines of North America, throughout the Caribbean, and along both … This DNA, a product of the egg’s cytoplasm is passed down only from mothers to their offspring, both male and female. This range of overlap is great enough to suggest that only the fastest of Clappers and the slowest of Kings are safely identifiable by this call. In the 1980s, Richard Zembal and Barbara Massey were the first to discover the meaning of this sound. King rails are larger than clapper rails and are more reddish with a rusty red-orange face. They are very similar to the King Rail… Learn how your comment data is processed. I highly recommend reading the dissertation. Thanks Nick for helping to shed light on the complexities of the research and the current state of bird taxonomy in light of genetics. I should also note that the abstract for the Condor paper proposes five, not four, species. You assume that individual clades are not only interbreeding, but taking up residence in each others territories. Thus, Zembal and Massey concluded that the “Kek-burr” is the female’s equivalent of the “Kek” Series — her way of advertising a burning urge to mate. You are more likely to hear this vocalization than the “Kek” Series. Even so, in the absence of selection against intermediate forms, significant nuclear DNA transfer would likely reveal itself phenotypically. Excellent news, Nick. It’s typically heard for a fairly brief period out of the year, and given only rarely after the singer is paired. I don’t mind being left in the dust if the truth will finally prevail. Purple gallinule. King and Clapper Rails are difficult to separate by physical appearance and there is currently no reliable method to distinguish between … King Rails occur widely in eastern North America, in eastern and central Mexico, and in Cuba. All words, images, and opinions are the property of their respective authors unless stated otherwise. It’s given by both sexes almost year-round, as a pair contact call and as a way of mediating territorial disputes with other pairs. So, Maley suggests recognizing four species, instead of the two currently recognized. Just like people buy specific passenger vehicles to accommodate their needs to transport passengers and cargo, a variety of rail … Distribution / Habitat. In the forthcoming article we suggest common names and detail our reasoning, which goes far beyond mitochondrial clades. The clapper rail (Rallus crepitans) is a member of the rail family, Rallidae.The taxonomy for this species is confusing and still being determined. If clade mtDNA mixing occurs, say on common wintering grounds, then the females later retreat to their own territories, you still can’t tell if interbreeding occurred from mtDNA. Sora. Here’s a useful snippet from the Sibley Guide to Birds: a series of unmusical kek notes, slower at beginning and end; the tempo of the fastest portion is useful for species identification. In a careful survey of all the rail recordings I could find online, I found the differences to be consistently smaller than this. #birdstagra, Clapper and King rails may represent four or five species, Mitochondrial and Next-Generation Sequence Data Used To Infer Phylogenetic Relationships and Species Limits in the Clapper/King Rail Complex, Enjoying the Common Birds at Central Park, Best Bird of the Weekend (Last of November 2020), An eastern clade comprising Clapper Rails of eastern North America and the Caribbean plus all King Rails. The Clapper Rail lives in similar habitat and regions as the King Rail and can also be found along the coastlines of Mexico. In California and Arizona, however, Clapper Rails are brightly colored and occur in both salt and freshwater environments. All these are separate from the longirostris group in South America. DNA tests to verify their relationship have so far been inconclusive. John A. Trent Carol Foil. The Toughest Birds to Record in North America. The newly abandoned female, #442, began to kek-burr on the following morning. The roots of the confusion go back to the East Coast, where there were two rail species: king rails and clapper rails. The Clapper Rails … Its call is a steady series of harsh notes, more staccato than the call of the very similar Clapper Rail… For humans, this vocalization is about as exciting as listening to a six-year-old incessantly rap a stick against a wooden fence. This study looked at both mitochondrial and nuclear DNA. An elegant dweller of freshwater and brackish marshes, the King Rail is a rich buffy bird with crisp stripes on its sides. He is a writer and communicator whose day jobs have taken him to six continents and more than 25 countries, including Papua New Guinea, Vanuatu, Kenya, and Cameroon. If only one sex/species alignment is viable (such as if female Clappers could breed with male Kings but not the other way around, sort of like how mules are made), they can’t really be said to interbreed freely. The mitochondria are in the cytoplasm, not the cell’s nucleus. Furthermore, some taxonomists consider that the King rail and Aztec rail … Traditionally, there were two species of large rails in the Americas. Then there were a bunch of different subspecies scattered around North and South America, including three here in California. The Grunt Series of the two species, like the “Kek” Series, are made of similar notes and are best distinguished by speed. During that day and the following one, #443 divided his time between the two females. Clapper Rails, as currently defined by the AOU, occur along the coasts of North and South America and Caribbean islands, and inland in southern California and Arizona. But even this statement requires a few caveats. Male Kings and male Clappers “sing” with the same notes — the key to identifying them is to li… This largest of North America’s rails is very secretive as it slips through short marsh vegetation in search of crayfish, crabs, and frogs. South of the ABA area, the picture is further complicated, but more on that in a bit. Feel free to contact us and don’t forget to subscribe! Adult King Rails usually have a rich orange breast sharply contrasting with strikingly barred flanks. I bring this up again, as no one has yet proffered an answer. In eastern North America, birders think of King Rails as richly colored birds of freshwater marshes, while Clapper Rails are considered drabber birds of saltmarshes . For one thing, Gulf Coast Clappers are brighter than East Coast Clappers, and the disjunct populations of “Light-footed” and “Yuma” Clappers in California and Arizona are brighter still, bright enough to have been considered subspecies of King Rail by some authors. Nesting in fresh-water marshes of the east, the King Rail has become an uncommon species as many wetlands have been drained. Underparts are orange-brown with strongly barred black, white flanks. Closely related to the Clapper Rail… Learn more about our site, Mike, Corey, or our awesome team of Beat Writers. The reddish upperwings separate King Rails from all races of Clapper Rail. Three-rail engines with Proto-Scale 3-2 are designed for operation on any type of 3-rail AC track system, and can quickly be converted for use on 2-rail DC layouts. King rail (call) call. These duets tend to go on longer than solo versions, and are less likely to accelerate at the end. The full study is fascinating and well worth a read. Black rail. In general the King Rail is a more brightly-colored bird of freshwater marshes, while the Clapper is a duller bird of coastal salt marshes. The Ridgway's rail (formerly the California clapper rail) and the mangrove rail have been recently split. For female rails, it must be quite an aphrodisiac, because it’s the primary way that males attract mates in early spring. Maley’s genetic work shows that the saltwater and freshwater populations are maintaining their distinctiveness in Louisiana. For humans, this vocalization is about as exciting as listening to a six-year-old incessantly rap a stick against a wooden fence. How does the study explain the significant differences in the calls of each bird/ species? This rarely-heard call is apparently given by alarmed rails near the nest. Clapper and King rails (Rallus longirostris and R. elegans) are the largest rails in the Americas. One morning, one of the males was killed by a Red-tailed Hawk.
