Knock knock, who's there? Spring!

Dendrocopos major poelzami is endemic to the Talysh Mountains. The smallest and darkest subspecies.
Iron tree - Parrotia persica, Persian ironwood tree - endemic, forms relict forests in Azerbaijan (Talysh Mountains) and Iran (Elborz) near the Caspian coast. The species is listed in the Red Book of the Republic of Azerbaijan.
The woodpecker's drum trill is its mating song. The woodpecker specifically chooses a tree where the wood resonates, as in musical instruments. As a rule, these are dead-topped trees or trees with dry branches that rise above the forest canopy.
This is how he marks his territory and gives a sign to the female. Ironwood, with its unique wood, is ideal for this.
