American Green Treefrog

• It gathers at house windows and street lamps to hunt the insects drawn in by the light, behaviour that has made it one of the most familiar frogs in the south-eastern United States.
• It is the state amphibian of Georgia and Louisiana, an uncommon distinction for a frog.
• Its call sounds like a repeated nasal honk, and the choruses of hundreds of males in the southern marshes are so loud that they carry more than a kilometre.
• It is the official state amphibian of Georgia and Louisiana.
• Its call is a repeated nasal bark that carries a long way when given in chorus, which is why it is also known in English as the cowbell frog.
• Males that fail to secure a territory adopt an alternative strategy: they stay silent beside a calling male and intercept the females that come to him. These are the so-called satellite males.
• It perches on vertical surfaces using adhesive toe pads, and shifts in shade between bright green and greyish brown depending on temperature, humidity and its condition.
• Its range is shifting northwards, and today it turns up in states where it was previously absent.
• Its scientific name changed from Hyla cinerea to Dryophytes cinereus with the revision of the New World hylid treefrogs.
