As regular CFZ-watchers will know, for some time Corinna has been doing a column for Animals & Men and a regular segment on On The Track... particularly about out-of-place birds and rare vagrants. There seem to be more and more bird stories from all over the world hitting the news these days so, to make room for them all - and to give them all equal and worthy coverage - she has set up this new blog to cover all things feathery and Fortean.

DNA Barcodes Made of 147 Bird Species from The Netherlands

Dec. 30, 2013 — DNA barcoding is used as an effective tool for both the identification of known species and the discovery of new ones. The core idea of DNA barcoding is based on the fact that just a small portion of a single gene already can show that there is less variation between the individuals of one species than between those of several species.

Thus, when comparing two barcode sequences one can establish whether these belong to one single species (viz. when the amount of variation falls within the 'normal' range of the taxon under consideration and below a certain threshold level) or possibly to two species (when the amount exceeds this level).
