Although we can not help you control the first reaction, we can at least shed a little light on the second.

A taxonomist is a scientist who classifies organisms into various categories. Carolus Linnaeus developed the taxonomy for animals in 1758, and we are still using his system of seven levels today: Kingdom, Phylum, Class, Order, Family, Genus, species. As science and methodologies become more advanced, researchers find new information (through DNA testing, for example) that may change the species' place in the taxonomic structure.

In the case of birds, taxonomic changes to the American Ornithology Union. The North American Classification Committee (NACC) for North and Middle American Birds is a group of taxonomists within that organization. NACC members review every proposal and determine which have sufficient merit to warrant current changes to the taxonomy. Those changes are published eleven a year. We may be a bit perplexed by a name or classification change, but now at least we know that current science is behind each decision.

Here are the changes to English and scientific names approved this year for Costa Rican birds, birds, birds, and birds.

Plain Wren has been split into three separate species.

  • Isthmian Wren (Cantorchilus elutus). Canebrake Wren (Cantorchilus zeledoni)
  • > Three-striped Warbler is now Gray-cowled Wood-Rail

    Blue-crowned Motmot is now Lesson's Motmot (Momotus lessoni).

    Pink-footed Shearwater

    (Puffinus creatopus) is now Ardenna creators
  • > Wedge-tailed Shearwater (Puffinus pacificus) is now Ardenna pacifica

  • Sooty Shearwater (Puffinus griseus) is now Ardenna grisea
  • Short-tailed Shearwater (Puffinus tenuirostris) is now Ardenna tenuirostris
  • Dusky Antbird (Hylophilus ochraceiceps) is now Tunchiornis ochraceiceps
  • Lesser Greenlet (Hylophilus decurtatus) is now Pachysylvia decurtata ​​li>

    After reading a previous article on this site about the name changes of some of our birds in Costa Rica, you are probably cursing the taxonomists op making themselves known who they are and what they do. Although we can not help you control the first reaction, we can at least help you with the second.

    Here are the changes in English and scientific names approved this year for birds in Costa Rica: Plain Wren has been divided into three separate species.

    • Isthmian Wren (Soterrey of Panama) The Canebrake Wren (Cantorchilus zeledoni)

    The Gray-necked Wood- (Cantorchilus zeledoni)

    Rail is now Gray-cowled Wood-Rail. It retains its name in Spanish (Rascón Cuelligrís).

    The Three-striped Warbler is now Costa Rican Warbler (Costa Rican Warbler).

    The Blue-crowned Motmot is now Lesson's Motmot (Momotus lessoni). It keeps its name in Spanish (Momoto Coroniazul).

    The Green Violetear is now Lesser Violetear. It keeps its name in Spanish (Colibrí Orejivioláceo Verde). Only the scientific names of the following species have changed.

    • Pink-footed Shearwater (Puffinus creatopus) is now Ardenna creators

    • Wedge-tailed Shearwater (Puffinus griseus) is now Ardenna grisea • Short-tailed Shearwater (Puffinus tenuirostris) (Pardella Colicorta) is now Ardenna tenuirostris (Pardella Colicuna) is now Ardenna pacifica

    • Sooty Shearwater (Puffinus griseus) Dusky Antbird (Cercomacra tyrannina) is now Cercomacroides tyrannina • Tawny-crowned Greenlet (Hylophilus ochraceiceps) is now Tunchiornis ochraceiceps

    • Lesser Greenlet (Hylophilus decurtatus) (Verdillo Menudo) is now Pachysylvia decurtata ​​p>
