Merulaxis Stresemanni
Stresemann's bristlefront (''Merulaxis stresemanni'') is a critically endangered species of bird in the family Rhinocryptidae, commonly known as tapaculos. It is endemic to Brazil, where it occupies a highly restricted and fragmented range. Taxonomy and systematics Stresemann's bristlefront and the slaty bristlefront (''Merulaxis ater'') are believed to form a superspecies, and some authorities suggest they may represent a single species. ''Merulaxis stresemanni'' is currently considered monotypic, with no recognized subspecies. The species is known from only three collected specimens, along with a handful of photographs, audio recordings, and documented sightings.Remsen, J. V., Jr., J. I. Areta, E. Bonaccorso, S.

Helmut Sick
Helmut Sick (10 January 1910 – 5 March 1991) was a German-Brazilian ornithologist. Sick was born in Leipzig, Germany. He emigrated to Brazil in 1939. A prominent ornithologist in Brazil Brazil, officially the Federative Republic of Brazil, is the largest country in South America. It is the world's List of countries and dependencies by area, fifth-largest country by area and the List of countries and dependencies by population ..., Sick published more than 200 papers, including his most influential work: ''Ornitologia Brasileira, Uma Introdução'' (1984), later translated into English as ''Birds in Brazil: A Natural History'' (1993). He also led scientific expeditions in remote areas in Brazil and described several species of birds, including the Brasília tapaculo, long-tailed cinclodes, Stresemann's bristlefront and golden-crowned manakin.

Secondary Forest
A secondary forest (or second-growth forest) is a forest or woodland area which has regenerated through largely natural processes after human-caused Disturbance (ecology), disturbances, such as Logging, timber harvest or agriculture clearing, or equivalently disruptive natural phenomena. It is distinguished from an old-growth forest (primary or primeval forest), which has not recently undergone such disruption, and complex early Seral community, 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 Ecological succession, regrowing after natural Disturbance (ecology), disturbances such as Wildfire, fire, insect infestation, or windthrow because the dead trees remain to provide nutrients, structure, and water retention after natural disturbances. Secondary forests are notably different from primary forests in their composition and biodiversity; however, they may still be hel ...

Birds Described In 1960
Birds are a group of warm-blooded vertebrates constituting the class (biology), class Aves (), characterised by feathers, toothless beaked jaws, the Oviparity, laying of Eggshell, hard-shelled eggs, a high Metabolism, metabolic rate, a four-chambered heart, and a strong yet lightweight Bird skeleton, skeleton. Birds live worldwide and range in size from the bee hummingbird to the common ostrich. There are over 11,000 living species and they are split into 44 Order (biology), orders. More than half are passerine or "perching" birds. Birds have Bird wing, wings 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 Flightless bird, loss of flight in some birds, including ratites, penguins, and diverse endemism, endemic island species. The digestive and respiratory systems of birds are also uniquely a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
