Thanks Nick for helping to shed light on the complexities of the research and the current state of bird taxonomy in light of genetics. Feel free to contact us and don’t forget to subscribe! This DNA, a product of the egg’s cytoplasm is passed down only from mothers to their offspring, both male and female. 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. Auk 79(3): 453-457. White-crowned Sparrow, Forest Park, Queens. It is noteworthy that a King Kings, meanwhile, seem to average between 2 and 3 notes per second. 1 King Rail Conservation Plan – Version 1 I. 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. The clapper rail is one of six rail species found in North Carolina. As intimated in the article, we also suggest splitting R. e. tenuirostris from the southwest North American group. These would be as follows (no English names proposed): So when might we see the AOU or other bodies deliberate this information? King Rails and Clapper Rails are sexually monomorphic in plumage, All subspecies, except the Northern Clapper Rail (R. l. crepitans), are non-migratory (Eddleman and Conway 1994). Your mitochondrial DNA is completely from your mother, in perpetuity. 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. Any loud noise may set off a Grunt Series, and one grunting rail often sets off another. pairings of King and Clapper rails (Poole et al. 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). The full study is fascinating and well worth a read. This largest of North America’s rails is very secretive as it slips through short marsh vegetation in search of crayfish, crabs, and frogs. Seemed closer in size to a Clapper Rail. A clade comprising Clapper Rails of California, Arizona, and northwest Mexico plus King Rails of the highlands of central Mexico. Notes: This little guy was searching for food on the edge of the marsh. This wetland is situated in a habitat migration corridor and hosts a variety of shore birds, including the endangered California Ridgeway’s (Clapper) Rail. Los Fresnos Texas. 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. 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. In 1992, broadcast calls were not used at most WMA's on the outer … The mangrove rail (Rallus longirostris) is a species of bird in the family Rallidae.It is found in Central and South America. I bring this up again, as no one has yet proffered an answer. 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. I usually do fine with refurbs results w/ refurbs, and that held true w/ the D500. This is no way to define a new species. These duets tend to go on longer than solo versions, and are less likely to accelerate at the end. Fascinating news (particularly identifying the hybrid zone on such a fine scale, and how salt is such a big obstacle to interbreeding) AND discussion. An elegant dweller of freshwater and brackish marshes, the King Rail is a rich buffy bird with crisp stripes on its sides. King Rails (actually Clapper Rails) Wow Tom, these are a first for me as well! Clapper Rails tend to occur in more saltwater wetlands, while King Rails tend to be in brackish or freshwater areas. 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?). The calls of Clapper Rail and King Rail overlap and so without verification by sight the identification of many calling birds is presumptive. 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. Few sportsmen see rails because few look for them. Do the arguments in Maley’s thesis make sense to you? Very dedicated and every so often, would snap up some morsel! 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. King Rail and chick in Illinois cc-by Andy Reago. Their taxonomic status long has been unclear due to their overall similarity and the fact that in eastern North America and Cuba, they hybridize. South of the ABA area, the picture is further complicated, but more on that in a bit. 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. come from Clapper Rails. This bird has some characteristics of Clapper and King, but size, flank barring, and black upper ground color tends toward King. In fact, no Sora nests were ever found. Mated pairs may perform extended, unsynchronized grunt duets, one starting slightly after the other, in one of nature’s least aesthetically pleasing romantic gestures. A clattering cackle in the salt marsh is often our first clue to the presence of this big rail. Clapper Rail. Its call is a steady series of harsh notes, more staccato than the call of the very similar Clapper Rail. 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. How does the study explain the significant differences in the calls of each bird/ species? King Rail. King Rails are associated with freshwater and brackish marshes, while Clapper Rails use brackish and saline marshes (Meanley 1992; Eddleman and Conway 1998). This site uses Akismet to reduce spam. […] 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.
