Taxonomy

Taxonomic note

Picoides tridactylus and P. funebris (del Hoyo and Collar 2014) were previously lumped as P. tridactylus following AOU (2003). P. tridactylus (del Hoyo and Collar 2014) was previously split into P. tridactylus and P. dorsalis following AOU (2003), and prior to that all three taxa were lumped as P. tridactylus following Sibley and Monroe (1990, 1993).

Population justification: The European population is estimated at 598,000-1,450,000 pairs, which equates to 1,200,000-2,900,000 mature individuals (BirdLife International 2015). Europe forms c.20% of the global range, so a very preliminary estimate of the global population size is 6,000,000-14,500,000 mature individuals, although further validation of this estimate is needed.

Trend justification: Although declines occurred in parts of its European range from 1970-2000, it has been stable across much of its European range during 1990-2000 (BirdLife International 2004), although the trend between 2000 and 2012 in Europe is unknown (BirdLife International 2015).
