difference between king rail and clapper rail

They were observing two color-banded pairs of “Light-footed” Clapper Rails in California. White-crowned Sparrow, Forest Park, Queens. American coot. 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. This DNA, a product of the egg’s cytoplasm is passed down only from mothers to their offspring, both male and female. And what are the conservation implications of elevating the endangered Pacific populations to full species status? The main differences between Suburban Rail and Rapid Transit Rail Networks is the services that they provide. DNA tests to verify their relationship have so far been inconclusive. Save my name, email, and website in this browser for the next time I comment. They have nothing at all to do with the 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. 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. That’s the original, time-honored and respected definition. The Ridgway's rail (formerly the California clapper rail) and the mangrove rail have been recently split. You probably know the difference between a sedan, an SUV and a pickup truck. King Rails occur widely in eastern North America, in eastern and central Mexico, and in Cuba. 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. The Clapper Rail was found along the Atlantic, Pacific, and Gulf coastlines of North America, throughout the Caribbean, and along both … 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 … These would be as follows (no English names proposed): So when might we see the AOU or other bodies deliberate this information? Adult King Rails usually have a rich orange breast sharply contrasting with strikingly barred flanks. 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. This site uses Akismet to reduce spam. I bring this up again, as no one has yet proffered an answer. Caribbean birds cluster with North American Clapper Rails. This study looked at both mitochondrial and nuclear DNA. There are very few recordings of this sound, but you can hear the hoot of a Clapper Rail here. True, there are definable differences in clades. This sparrow-sized bird also prefers a habitat along the coastline in the same regions as the other rails. 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. You assume that individual clades are not only interbreeding, but taking up residence in each others territories. The Grunt Series of the two species, like the “Kek” Series, are made of similar notes and are best distinguished by speed. These would be as follows (no English names proposed): So when might we see the AOU or other bodies deliberate this information? Closely related to the Clapper Rail… 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. King and Clapper rails coexist along a salinity gradient within marshes of the Atlantic and Gulf coasts of the United States. 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. Common gallinule. Traditionally, there were two species of large rails in the Americas. One morning, one of the males was killed by a Red-tailed Hawk. I wanted to point out that this work was done with Robb Brumfield (my adviser). The full study is fascinating and well worth a read. Genetic studies on bird populations are almost always done on mitochondrial DNA. King Rail and chick in Illinois cc-by Andy Reago. The Toughest Birds to Record in North America. I highly recommend reading the dissertation. They are very similar to the King Rail… … The deeper flanges on locomotives with hi-rail wheels, however, may contact the track ties on low profile 2-rail … In California and Arizona, however, Clapper Rails are brightly colored and occur in both salt and freshwater environments. Thanks David for the excellent article summarizing my research on this complex! 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. See the recent discussion on BirdForum for a little more info. 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. Prominent chestnut-brown patch on wing is … 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. California’s three subspecies of Rallus longirostris become subspecies of Rallus obsoletus , which is given the English name Ridgway’s Rail. This secretive bird lives most of its life concealed in dense vegetation. This rarely-heard call is apparently given by alarmed rails near the nest. King Rails occur widely in eastern North America, in eastern and central Mexico, and in Cuba. 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. For female rails, it must be quite an aphrodisiac, because it’s the primary way that males attract mates in early spring. Also, king rails … It’s typically heard for a fairly brief period out of the year, and given only rarely after the singer is paired. Male Kings and male Clappers “sing” with the same notes — the key to identifying them is to li… Long, consistent bouts of typical calls can be reliably identified. What English names would you propose if the complex is split into four or five new species? The Clapper Rail lives in similar habitat and regions as the King Rail and can also be found along the coastlines of Mexico. 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. Although mitochondrial DNA does replicate as new mitochondria are produced, no sex is involved. Thanks everyone. 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. For humans, this vocalization is about as exciting as listening to a six-year-old incessantly rap a stick against a wooden fence. Two days later, his mate (#421) began giving the “Kek-burr” call. Clapper rails are closely related to all members of the genus Rallus but are geographically closest to the king 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. In the forthcoming article we suggest common names and detail our reasoning, which goes far beyond mitochondrial clades. 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. King rails inhabit both freshwater and brackish marshes, while Clapper rails reside in tidal salt marshes (Meanley, 1985). During that day and the following one, #443 divided his time between the two females. Its call is a steady series of harsh notes, more staccato than the call of the very similar Clapper Rail… By … […] Individuals may give faster or slower calls depending on mood, but such departures are usually brief. King and Clapper Rails are difficult to separate by physical appearance and there is currently no reliable method to distinguish between … Any loud noise may set off a Grunt Series, and one grunting rail often sets off another. 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. Excellent news, Nick. Clapper Rail of the grayish U.S. Atlantic Coast subspecies crepitans in New Jersey by Corey Finger. Clapper Rail: Large, noisy marsh bird, gray or brown upperparts, vertical white-barred flanks and belly, buff or rust-brown breast. A clade comprising Clapper Rails of California, Arizona, and northwest Mexico plus King Rails of the highlands of central Mexico. This largest of North America’s rails is very secretive as it slips through short marsh vegetation in search of crayfish, crabs, and frogs. Clapper and King rails (Rallus longirostris and R. elegans) are the largest rails in the Americas. All words, images, and opinions are the property of their respective authors unless stated otherwise. 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. A clattering cackle in the salt marsh is often our first clue to the presence of this big rail. The clapper rail (Rallus crepitans) is a member of the rail family, Rallidae.The taxonomy for this species is confusing and still being determined. The photo above, one of mine, shows a Clapper Rail in Louisiana. Male Kings and male Clappers “sing” with the same notes — the key to identifying them is to listen to the speed of their calls. The Clapper Rail is usually hidden in dense cover, but sometimes we see it stalking boldly along the muddy edge of the … If you’ve got recordings, I’d love to hear them. The Clapper Rail is a large rail that is primarily found in salt marshes of the Eastern United States. However, the Clapper Rails show a definite preference for salt water marshes and the King Rails typically frequent fresh-water habitats. Our Bird B is much more subtle than that, and while its orange-ish breast is rather more vibrant than … Brown and red-brown mottled upperparts. The roots of the confusion go back to the East Coast, where there were two rail species: king rails and clapper rails. All these are separate from the longirostris group in South America. Nesting in fresh-water marshes of the east, the King Rail has become an uncommon species as many wetlands have been drained. 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 large Clapper Rail is abundant in saltwater marshes and mangrove swamps from the U.S. East Coast to Central America and the Caribbean. Distribution / Habitat. Underparts are orange-brown with strongly barred black, white flanks. The mitochondria are in the cytoplasm, not the cell’s nucleus. The need for cubbyholes for all these forms is why there are subspecies in the first place. During one exchange he traveled the 190 m to the calling female within 18 min of the onset of kek-burring. The Clapper Rails … The newly abandoned female, #442, began to kek-burr on the following morning. Excited birds may give many rapid “Keks” before the burr; in some situations, the burr is given separately. How does the study explain the significant differences in the calls of each bird/ species? The Black Rail is the smallest member of the rail family. South of the ABA area, the picture is further complicated, but more on that in a bit. #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. Also, if both sexes are interbreeding with other clades, the two mtDNA lineages will be spread throughout both species. Yellow rail. Learn how your comment data is processed. That would require all of the female hybrids to return to their mothers’ breeding grounds. Mitochondrial DNA is used in genetic studies because of its higher mutation rate, making it more valuable when looking for changes. 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. King rail (call) call. In 2014, the species was split into three: Clapper Rail; Ridgway's Rail of California, Arizona, and Nevada; and Mangrove Rail … 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. Clapper rail. James has reams of next-generation nuclear DNA sequencing data that shows hybridization dynamics at a fine scale. In the case presented here, a female rail could be fooling around with males Even so, in the absence of selection against intermediate forms, significant nuclear DNA transfer would likely reveal itself phenotypically. 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. Steve, King rails are larger than clapper rails and are more reddish with a rusty red-orange face. 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. Black rail. These duets tend to go on longer than solo versions, and are less likely to accelerate at the end. I don’t mind being left in the dust if the truth will finally prevail. 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. Welcome to 10,000 Birds, the world’s favorite birding blog! 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. All subspecies, except the Northern Clapper Rail (R. l. crepitans), are non-migratory (Eddleman and Conway 1994). As intimated in the article, we also suggest splitting R. e. tenuirostris from the southwest North American group. Also, your statement that “Genetic studies on bird populations are almost always done on mitochondrial DNA” is not really true anymore. 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. Flight is low and fluttering over short distances. David J. Ringer is exploring the world one bird at a time. Maley’s genetic work shows that the saltwater and freshwater populations are maintaining their distinctiveness in Louisiana. In freshwater rails, this gland is smaller, and the birds do not fare well in saltier environments. Just like people buy specific passenger vehicles to accommodate their needs to transport passengers and cargo, a variety of rail … 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. For humans, this vocalization is about as exciting as listening to a six-year-old incessantly rap a stick against a wooden fence. nuclear DNA of classic genetics. What do you think? Purple gallinule. But identifying a group of birds as a “species” implies that the group is reproductively isolated from other groups. An elegant dweller of freshwater and brackish marshes, the King Rail is a rich buffy bird with crisp stripes on its sides. 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. So, Maley suggests recognizing four species, instead of the two currently recognized. In a careful survey of all the rail recordings I could find online, I found the differences to be consistently smaller than this. But some recent work by James Maley and others is shedding more light on these secretive and fascinating birds. The reddish upperwings separate King Rails from all races of Clapper Rail. But even they can get up pretty far into Clapper speed if they feel particularly motivated. Mated pairs may perform extended, unsynchronized grunt duets, one starting slightly after the other, in one of nature’s least aesthetically pleasing romantic gestures. (I assume here that specimens were obtained on home territories). 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. of nearby clades, produce viable young, and no one would know because they are only looking at the mitochondrial DNA. The Clapper Rail is usually hidden in dense cover, but sometimes we see it … But even this statement requires a few caveats. 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. Without the aid of a full-time mate, #421 abandoned her nest. But do you know the difference between a boxcar, a tank car and a gondola? You are more likely to hear this vocalization than the “Kek” Series. King Rail: Large rail with long, orange-based bill. Other rails, gallinules and coots. We witnessed #443 respond to kek-burring 11 times in 36.1 h of observations over 4 days. Virginia rail. In both proposals, we’d end up with 3 species of large rail in North America: King, “eastern” Clapper, and “western” Clapper. One of those is the one we've been calling the California clapper rail. Bill is long, slightly decurved. 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. 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. It’s typically heard for a fairly brief period out of the year, and given only rarely after the singer is paired. The CA delta region … According to Sibley, eastern Clapper Rails “kek” at about 4-5 notes per second, while Kings are slower, usually 2 notes per second. King Rails are associated with freshwater and brackish marshes, while Clapper Rails … John A. Trent Carol Foil. Kings, meanwhile, seem to average between 2 and 3 notes per second. 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. 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. Perhaps tenuirostris of Central Mexico is proposed as a full species, instead of being lumped with the endangered Pacific and Baja populations? • 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. Do the arguments in Maley’s thesis make sense to you? Then there were a bunch of different subspecies scattered around North and South America, including three here in California. Ridgway's rail. 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. Yellow-breasted Chat, Jamaica Bay Wildlife Refuge, Jamaican Lizard-Cuckoo, February 2020. For female rails, it must be quite an aphrodisiac, because it’s the primary way that males attract mates in early spring. In the 1980s, Richard Zembal and Barbara Massey were the first to discover the meaning of this sound. Your mitochondrial DNA is completely from your mother, in perpetuity. #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.
