Canebrake Wren
The canebrake wren (''Cantorchilus zeledoni'') is a species of bird in the family Troglodytidae. It is found in Costa Rica, Nicaragua, and Panama. Taxonomy and systematics The canebrake wren, with what are now Cabanis's wren (''C. modestus'') and the isthmian wren (''C. elutus''), were called the plain wren. The three were split from each other in 2016 on the basis of a 2015 publication that described their different vocalizations and genetic divergence. The canebrake wren is monotypic. Description The canebrake wren is long. Adults' crowns are brown and their upperparts are brownish gray merging to olivaceous gray on the rump. Their tail is olivaceous brown with well defined darker bars. They have a white supercilium, a gray-brown stripe through the eye, and cheeks mottled with gray and off-white. The throat is off white, the chest gray, and the lower belly gray-buff. Juveniles have duller underparts and less well defined facial markings.Kroodsma, D. E. and D. Brewer (2020 ...

Robert Ridgway
Robert Ridgway (July 2, 1850 – March 25, 1929) was an American ornithologist specializing in systematics. He was appointed in 1880 by Spencer Fullerton Baird, secretary of the Smithsonian Institution, to be the first full-time curator of birds at the United States National Museum, a title he held until his death. In 1883, he helped found the American Ornithologists' Union, where he served as officer and journal editor. Ridgway was an outstanding descriptive taxonomist, capping his life work with ''The Birds of North and Middle America'' (eight volumes, 1901–1919). In his lifetime, he was unmatched in the number of North American bird species that he described for science. As technical illustrator, Ridgway used his own paintings and outline drawings to complement his writing. He also published two books that systematized color names for describing birds, ''A Nomenclature of Colors for Naturalists'' (1886) and ''Color Standards and Color Nomenclature'' (1912). Ornithol ...

Secondary Forest
A secondary forest (or second-growth forest) is a forest or woodland area which has re-grown after a timber harvest or clearing for agriculture, until a long enough period has passed so that the effects of the disturbance are no longer evident. It is distinguished from an old-growth forest (primary or primeval forest), which has not recently undergone such disruption, and complex early seral forest, as well as third-growth forests that result from harvest in second growth forests. Secondary forest regrowing after timber harvest differs from forest regrowing after natural disturbances such as fire, insect infestation, or windthrow because the dead trees remain to provide nutrients, structure, and water retention after natural disturbances. However, often after natural disturbance the timber is harvested and removed from the system, in which case the system more closely resembles secondary forest rather than seral forest.

Birds Of Nicaragua
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cantorchilus
''Cantorchilus'' is a genus of birds in the wren family. Established by Nigel I. Mann, F. Keith Barker, Jeff A. Graves, Kimberly A. Dingess-Mann and Peter J. B. Slater in 2006, it contains 10 species. All of the species assigned to it were previously included in the genus ''Thryothorus''. Species * Stripe-breasted wren (''Cantorchilus thoracicus'') * Stripe-throated wren (''Cantorchilus leucopogon'') * Cabanis's wren (''Cantorchilus modestus'') * Canebrake wren (''Cantorchilus zeledoni'') * Isthmian wren (''Cantorchilus elutus'') * Riverside wren (''Cantorchilus semibadius'') * Bay wren (''Cantorchilus nigricapillus'') * Superciliated wren (''Cantorchilus superciliaris'') * Buff-breasted wren (''Cantorchilus leucotis'') (probably not monophyletic In cladistics for a group of organisms, monophyly is the condition of being a clade—that is, a group of taxa composed only of a common ancestor (or more precisely an ancestral population) and all of its lineal descenda ...

IUCN
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wider ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canebrake
A canebrake or canebreak is a thicket of any of a variety of '' Arundinaria'' grasses: '' A. gigantea'', '' A. tecta'' and '' A. appalachiana''. As a bamboo, these giant grasses grow in thickets up to 24 ft tall. ''A. gigantea'' is generally found in stream valleys and ravines throughout the southeastern United States. ''A. tecta'' is a smaller stature species found on the Atlantic and Gulf Coastal Plains. Finally, ''A. appalachiana'' is found in more upland areas at the southern end of the Appalachian mountains. Cane does not do well on sites that meet wetland classification; instead canebrakes are characteristic of moist lowland, floodplain areas that are not as saturated as true wetlands. Canebrakes were formerly widespread in the Southern United States, potentially covering 10 million acres, but have been widely replaced by agriculture. This destruction has impacted a number of species. The survival of the Florida panther (''Puma concolor'' subsp. ''coryi'') has been cha ...

Supercilium
The supercilium is a plumage feature found on the heads of some bird species. It is a stripe which runs from the base of the bird's beak above its eye, finishing somewhere towards the rear of the bird's head.Dunn and Alderfer (2006), p. 10 Also known as an "eyebrow", it is distinct from the eyestripe, which is a line that runs across the lores, and continues behind the eye. Where a stripe is present only above the lores, and does not continue behind the eye, it is called a supraloral stripe or simply supraloral. On most species which display a supercilium, it is paler than the adjacent feather tracts. The colour, shape or other features of the supercilium can be useful in bird identification. For example, the supercilium of the dusky warbler, an Old World warbler species, can be used to distinguish it from the very similar Radde's warbler. The dusky warbler's supercilium is sharply demarcated, whitish and narrow in front of the eye, becoming broader and more buffy towards th ...

Monotypic
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, '' Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda.' ...

Isthmian Wren
The isthmian wren (''Cantorchilus elutus'') is a species of bird in the family Troglodytidae. It is found in Costa Rica and Panama. Taxonomy and systematics The isthmian wren, with what are now Cabanis's wren (''C. modestus'') and the canebrake wren (''C. zeledoni''), were called the plain wren. A 2015 publication described their different vocalizations and genetic divergence. In 2016 the International Ornithological Committee (IOC) and the Clements taxonomy accepted the split of plain wren into three species.Clements, J. F., T. S. Schulenberg, M. J. Iliff, S. M. Billerman, T. A. Fredericks, B. L. Sullivan, and C. L. Wood. 2019. The eBird/Clements Checklist of Birds of the World: v2019. Downloaded from https://www.birds.cornell.edu/clementschecklist/download/ Retrieved August 15, 2019 However, BirdLife International (BLI) retains ''C. modestus'' as "plain wren" with ''elutus'' as a subspecies of it rather than as a full species.HBW and BirdLife International (2020) ''Handbook ...
