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. Here are a few of the reasons why this is the case.

Here are the changes to English and scientific names 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 taking into account 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.
