Muted barking in trees 30 metres across swamp grasses led me to Common Tree Snake trying to eat big pale-hued White-lipped Tree Frog in Tyto today.
First strike got frog behind front leg. Some blood flowed down side. Grip later shifted - before my arrival - to rear foot. Usual frog defence: make a lot of noise and either wedge into crevice or try to walk away.
Frog won - as I was changing lenses! Makes it Frogs 4 Snakes 0 for my sightings over recent years. But in all cases the frogs were large and the tree snakes moderate in length (about 1m).
No great pix from any of the four contests, but above, from three years back, is best.
