Clapper and King rails (Rallus longirostris and R. elegans) are the largest rails in the Americas. 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. Robert E. Stewart (pers. In the 1980s, Richard Zembal and Barbara Massey were the first to discover the meaning of this sound.  They were observing two color-banded pairs of “Light-footed” Clapper Rails in California. For humans, this vocalization is about as exciting as listening to a six-year-old incessantly rap a stick against a wooden fence. It really looked unused, flawless all round in fact. 1 Species ID Suggestions +2. Without the aid of a full-time mate, #421 abandoned her nest. A clade comprising Clapper Rails of California, Arizona, and northwest Mexico plus King Rails of the highlands of central Mexico. The clapper rail is listed as a game bird and can Your mitochondrial DNA is completely from your mother, in perpetuity. Can look very similar to King Rail. All King-Clapper type rail calls heard at inland sites were counted as King Rails. Do the arguments in Maley’s thesis make sense to you? king rail and the clapper rail will be compared and discussed. 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. Follow him on Twitter at, Best Bird of the Weekend (Third of April 2013), © 2019 10,000 Birds // All rights reserved. Clapper Rails have gray cheeks, less distinct striping on the flanks, and are often paler cinnamon than King Rails. Meanley, B. and D. K. Wetherbee. How does the study explain the significant differences in the calls of each bird/ species? This is a probable King Rail based on the steady, slower pace of the notes over a long period of time, and the fact that it was recorded at a known King Rail … Seemed closer in size to a Clapper Rail. Species synopsis: King rail is closely related to clapper rail (Rallus longirostris) and interbreeding between the two has been the subject of considerable scientific speculation. A total of 263 King or Clapper Rails were seen or heard, of which 67 were considered King Rails. In California and Arizona, however, Clapper Rails are brightly colored and occur in both salt and freshwater environments. Perkins, M. 2007. nuclear DNA of classic genetics. While easy for North American birders to adjust to, retaining a common name previously used for the pre-split species for one of the new forms is generally not done so as to avoid confusion. 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. This largest of North America’s rails is very secretive as it slips through short marsh vegetation in search of crayfish, crabs, and frogs. North American Fauna No. In the forthcoming article we suggest common names and detail our reasoning, which goes far beyond mitochondrial clades. Excited birds may give many rapid “Keks” before the burr; in some situations, the burr is given separately. An elegant dweller of freshwater and brackish marshes, the King Rail is a rich buffy bird with crisp stripes on its sides. Bird had tan/ brown cheeks vs gray cheeks on Virginia. 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. During one exchange he traveled the 190 m to the calling female within 18 min of the onset of kek-burring. The Grunt Series of the two species, like the “Kek” Series, are made of similar notes and are best distinguished by speed. 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. You are more likely to hear this vocalization than the “Kek” Series.  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. trends for King Rail in the Delmarva Peninsula, our goal in this project was to use standardized protocols to sample historic known King Rail sites and new marshes to evaluate King and Clapper rail populations in the Delmarva Peninsula in 2014 and 2015. In fact, no Sora nests were ever found. 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. Thanks David for the excellent article summarizing my research on this complex! 2015-04-12 Rallus elegans Rascón Real, rascón elegante, gallinuela de agua dulce, rascón real o … This bird has some characteristics of Clapper and King, but size, flank barring, and black upper ground color tends toward King. Clapper Rail. The Toughest Birds to Record in North America. Genetic studies on bird populations are almost always done on mitochondrial DNA. The photo above, one of mine, shows a Clapper Rail in Louisiana. Clapper Rail of the grayish U.S. Atlantic Coast subspecies crepitans in New Jersey by Corey Finger. You assume that individual clades are not only interbreeding, but taking up residence in each others territories. Also, your statement that “Genetic studies on bird populations are almost always done on mitochondrial DNA” is not really true anymore. During that day and the following one, #443 divided his time between the two females. Los Fresnos Texas. King Rails occur widely in eastern North America, in eastern and central Mexico, and in Cuba. Underparts are orange-brown with strongly barred black, white flanks. 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. King (female?) King Rails and Clapper Rails are sexually monomorphic in plumage, although males are larger than females for both species (Meanley 1992; Eddleman and Conway 1998). King Rail: Large rail with long, orange-based bill. 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. […] Individuals may give faster or slower calls depending on mood, but such departures are usually brief.  Long, consistent bouts of typical calls can be reliably identified. But even this statement requires a few caveats. come from Clapper Rails. But even they can get up pretty far into Clapper speed if they feel particularly motivated.  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?). David J. Ringer is exploring the world one bird at a time. Notes: This little guy was searching for food on the edge of the marsh. Rail (Meanley 1992). Kings, meanwhile, seem to average between 2 and 3 notes per second. That would require all of the female hybrids to return to their mothers’ breeding grounds. I wanted to point out that this work was done with Robb Brumfield (my adviser). But some recent work by James Maley and others is shedding more light on these secretive and fascinating birds. For female rails, it must be quite an aphrodisiac, because it’s the primary way that males attract mates in early spring. King (female?) The use of stable isotopes to determine the ratio of resident to migrant king est tidal water source. Rallus definition is - the type genus of Rallidae comprising slender-billed rails (as the European water rail, the clapper rail, and the king rail). California’s three subspecies of Rallus longirostris become subspecies of Rallus obsoletus, which is given the English name Ridgway’s Rail. Perhaps tenuirostris of Central Mexico is proposed as a full species, instead of being lumped with the endangered Pacific and Baja populations? The calls of Clapper Rail and King Rail overlap and so without verification by sight the identification of many calling birds is presumptive. This DNA, a product of the egg’s cytoplasm is passed down only from mothers to their offspring, both male and female. One subspecies of Clapper Rail occurs in Arizona’s freshwater marsh. 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. This rarely-heard call is apparently given by alarmed rails near the nest.  There are very few recordings of this sound, but you can hear the hoot of a Clapper Rail here.  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. 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. 2005). This bird has some characteristics of Clapper and King, but size, flank barring, and black upper ground color tends toward King. 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. 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. It is noteworthy that a King Atlantic coast birds dull grayish-brown overall with few contrasting features; faintly barred gray-and-white on sides and pale orange bill. Very dedicated and every so often, would snap up some morsel! This wetland is situated in a habitat migration corridor and hosts a variety of shore birds, including the endangered California Ridgeway’s (Clapper) Rail. Four species — clapper, sora, Virginia and king rails — are hunted in the U.S. in the Atlantic, Mississippi and Central flyways. World Bird Guide:: Rails, Gallinules and Coots:: King Rail. We witnessed #443 respond to kek-burring 11 times in 36.1 h of observations over 4 days. These would be as follows (no English names proposed): So when might we see the AOU or other bodies deliberate this information? 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. 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. Taxonomic uncertainties concerning the subspecies of the clapper rail also will be briefly discussed. Clapper Rails tend to occur in more saltwater wetlands, while King Rails tend to be in brackish or freshwater areas. #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, Mitochondrial mysteries and splitting-lumping Yellow-rumped Warblers, 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 king rail is a rare breeder in New York. So, Maley suggests recognizing four species, instead of the two currently recognized. Other rail species that occupied the marsh were Soras (Porzana caro-lia) and King Rails (Rallus elegans). Details: Waiting on more eyes to inspect photos, possibly a King Rail. In freshwater rails, this gland is smaller, and the birds do not fare well in saltier environments. ForestDragon 7 years ago. I usually do fine with refurbs results w/ refurbs, and that held true w/ the D500. Welcome to 10,000 Birds, the world’s favorite birding blog! pairings of King and Clapper rails (Poole et al. All subspecies, except the Northern Clapper Rail (R. l. crepitans), are non-migratory (Eddleman and Conway 1994). South of the ABA area, the picture is further complicated, but more on that in a bit. This largest of North America’s rails is very secretive as it slips through short marsh vegetation in search of crayfish, crabs, and frogs. 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. Any loud noise may set off a Grunt Series, and one grunting rail often sets off another. This site uses Akismet to reduce spam. The full study is fascinating and well worth a read. Some authorities consider the two forms to be conspecific. Few sportsmen see rails because few look for them. 1962. We used … That’s the original, time-honored and respected definition. The daily bag limit is 15 king or clapper rails and 25 sora or Virginia rails. In both proposals, we’d end up with 3 species of large rail in North America: King, “eastern” Clapper, and “western” Clapper.  See the recent discussion on BirdForum for a little more info. I bring this up again, as no one has yet proffered an answer. 67. We had no difficulties discerning Clapper Rail nests be-cause Sora eggs are much smaller than Clapper Rail eggs, and their nests are structurally differ-ent (Taylor 1998). Be sure to browse our extensive galleries, species accounts, and book and product reviews. 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. Its call is a steady series of harsh notes, more staccato than the call of the very similar Clapper Rail. By Chris Duke Updated October 2, 2018. Male Kings and male Clappers “sing” with the same notes — the key to identifying them is to listen to the speed of their calls.  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. Male Kings and male Clappers “sing” with the same notes — the key to identifying them is to li… 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. Fascinating news (particularly identifying the hybrid zone on such a fine scale, and how salt is such a big obstacle to interbreeding) AND discussion. 1969. It really looked unused, flawless all round in fact. Although mitochondrial DNA does replicate as new mitochondria are produced, no sex is involved. Fish and Wildlife Service Focal Species, is a large rail found locally in freshwater wetlands throughout the eastern United States, southern Ontario, central Mexico, and Cuba. King Rails and Clapper Rails are sexually monomorphic in plumage, His fascination with birds and nature began at the age of four or five, and he now works full time in conservation. Clapper Rail • 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. 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. 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. Prominent chestnut-brown patch on wing is visible on standing and flying birds. Learn how your comment data is processed. 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. 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. This species It’s typically heard for a fairly brief period out of the year, and given only rarely after the singer is paired. The mitochondria are in the cytoplasm, not the cell’s nucleus. Natural history of the King Rail. In California and Arizona, however, Clapper Rails are brightly colored and occur in both salt and freshwater environments. 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. Also, if both sexes are interbreeding with other clades, the two mtDNA lineages will be spread throughout both species. 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. Mitochondrial DNA is used in genetic studies because of its higher mutation rate, making it more valuable when looking for changes. In the case of king and clapper rails, environmental factors associated with climate change are most likely facilitating the invasion of clapper rails and displacement of king rails in these brackish marshes. marshes occur where King and Clapper rails may be found together. Maley’s genetic work shows that the saltwater and freshwater populations are maintaining their distinctiveness in Louisiana. Auk 79(3): 453-457. #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. You sure did a great job with the opportunity you were offered. The newly abandoned female, #442, began to kek-burr on the following morning. The rich red/ cinnamon color on the back and wings stood out quite a bit. Executive Summary The King Rail (Rallus elegans), a U.S. photo by Robert Ostrowski. The California Ridgeway’s Rail (formerly Clapper Rail) or Rallus longirostris obsoletus is one of the most endangered birds in California.. Santa Venetia Marsh Open Space Preserve is a fragile salt water marsh ecosystem in North San Rafael. In this instance, an individual of the typically fresh to brackish water inhabitant King Rail survived, nested, and successfully fledged young in a high salinity saltmarsh habitat, typically regarded as optimal Clapper Rail habitat. True, there are definable differences in clades. King Rails (actually Clapper Rails) Wow Tom, these are a first for me as well! 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. The clapper rail, often called the mud or marsh hen, is abundant in the salt marsh and mangrove swamps of the Atlantic and Gulf coasts of the United States. This is the vocalization that Sibley refers to as “a raucous squawk like a startled chicken”.  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. The need for cubbyholes for all these forms is why there are subspecies in the first place. (I assume here that specimens were obtained on home territories). Even so, in the absence of selection against intermediate forms, significant nuclear DNA transfer would likely reveal itself phenotypically. Yellow-breasted Chat, Jamaica Bay Wildlife Refuge, Jamaican Lizard-Cuckoo, February 2020. Rallus longirostris. I highly recommend reading the dissertation. James has reams of next-generation nuclear DNA sequencing data that shows hybridization dynamics at a fine scale. Historical . King Rails are associated with freshwater and brackish marshes, while Clapper Rails use brackish and saline marshes (Meanley 1992; Eddleman and Conway 1998). Mated pairs may perform extended, unsynchronized grunt duets, one starting slightly after the other, in one of nature’s least aesthetically pleasing romantic gestures. One morning, one of the males was killed by a Red-tailed Hawk.  Two days later, his mate (#421) began giving the “Kek-burr” call. Thanks everyone. 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. Tweet; Habitat: Bothin Marsh Preserve, Mill Valley, CA. A clattering cackle in the salt marsh is often our first clue to the presence of this big rail. Graves (2001) found that King Rails and Clapper Rails could be distinguished through discriminant analysis of … At this time Adorama had the best price. of nearby clades, produce viable young, and no one would know because they are only looking at the mitochondrial DNA. Feel free to contact us and don’t forget to subscribe! Learn more about our site, Mike, Corey, or our awesome team of Beat Writers. And what are the conservation implications of elevating the endangered Pacific populations to full species status? What do you think? The clapper rail is one of six rail species found in North Carolina. Excellent news, Nick. The others include the sora, Virginia, king, black and yellow rail. According to Sibley, eastern Clapper Rails “kek” at about 4-5 notes per second, while Kings are slower, usually 2 notes per second.  In a careful survey of all the rail recordings I could find online, I found the differences to be consistently smaller than this. As intimated in the article, we also suggest splitting R. e. tenuirostris from the southwest North American group. All words, images, and opinions are the property of their respective authors unless stated otherwise. In 1992, broadcast calls were not used at most WMA's on the outer … Fog curled and rose from the marsh as the sun set. It was formerly considered conspecific with the clapper rail (Rallus crepitans).. Its natural habitats are subtropical or tropical mangrove forests and coastal saline lagoons.It is threatened by habitat loss.. Taxonomy. 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. What English names would you propose if the complex is split into four or five new species? comm., 3 May 1960) observed a King Rail and Clapper Rail together with a brood at Chincoteague Island on the coast of Virginia in June 1951. The mangrove rail (Rallus longirostris) is a species of bird in the family Rallidae.It is found in Central and South America. For humans, this vocalization is about as exciting as listening to a six-year-old incessantly rap a stick against a wooden fence.  For female rails, it must be quite an aphrodisiac, because it’s the primary way that males attract mates in early spring.  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. At this time Adorama had the best price. 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.  If you’ve got recordings, I’d love to hear them. Feeds in shallow water or mudflats exposed at low tide. This is no way to define a new species. Even with this variety of rail species, the clapper rail is likely only to be confused with the king rail, a slightly larger bird that prefers freshwater marshes. 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. The Clapper Rail is usually hidden in dense cover, but sometimes we see it stalking boldly along the muddy edge of the marsh, twitching its short tail as it walks, or swimming across a tidal creek. A Clapper Rail and a King Rail, or a Saltmarsh Rail and a Elegant Rail? These duets tend to go on longer than solo versions, and are less likely to accelerate at the end. Clapper Rails are more drab in col-or, gray or dull brown, in comparison to the brighter, reddish coloration of King Rails (Eddleman and Conway 1998), but the sub-species of Clapper Rail that occurs along the Gulf Coast has coloration similar to the King Rail (Meanley 1992). 1 King Rail Conservation Plan – Version 1 I. King Rail Rallus elegans Described by: Audubon (1834) Alternate common name(s): Highland Rail, Mexican Clapper Rail Old scientific name(s): None known by website authors Photographs Select thumbnail to view larger image - Place cursor over image for image information All these are separate from the longirostris group in South America.  Caribbean birds cluster with North American Clapper Rails. Atlantic coast birds dull grayish-brown overall with few contrasting features; faintly barred gray-and-white on sides and pale orange bill. 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. King Rail. vs Clapper Rail, Anahuac NWR. 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. Meanley, B. Number observed: 1. 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. per Rail. comm.).
