🐦Acorn Woodpecker
Der Eichelspecht (Melanerpes formicivorus) ist ein mittelgroßer Vertreter der Gattung Melanerpes innerhalb der Unterfamilie der Echten Spechte (Picinae). Die auffällige und nicht seltene Art ist vom Südwesten Washingtons südwärts bis ins nordwestliche Südamerika verbreitet. Wie einige andere Melanerpes-Arten leben auch Eichelspechte meist in Familiengruppen, in denen eine höchst differenzierte Sozialstruktur ausgebildet ist. Die geographische Variation ist groß: Es werden über zehn Unterarten beschrieben, von denen sieben allgemein anerkannt sind. Fast alle Unterarten sind Standvögel und betreiben eine intensive herbstliche Vorratshaltung.
