🐍Eastern racer

Coluber constrictor Linnaeus, 1758

Die Schwarznatter (Coluber constrictor), auch Amerikanische Zornnatter genannt, gehört zu den harmlosen Schlangen in Nordamerika. Sie bewegt sich sehr schnell und wird insbesondere in den Gärten von Dörfern und Vororten öfter angetroffen. Daher rührt auch ihr englischer Name Northern oder Eastern (Black) Racer. Als Nahrung dienen ihr überwiegend Vögel und deren Gelege, aber auch andere Kleintiere, wie Insekten und Amphibien.
