Rain flushes out hibernators
In July and then in August we had a dump of rain that caused minor floods along the Ovens River. It also triggered some crazed activity by wombats, who started a digging/renovation frenzy a day or two after the rain had finished and the floodwaters receded. (On our place most of the wombat dwellings are along the river banks. When the river rises some of these get filled with water.)
The dredgehole in the goose paddock filled up with water. By "filled" I mean it has more than a metre of water. A few years ago it had 6 metres depth, so ine metre is still a long way from replenished. But it feels filled, because its been dry for more than 18 months, and the frogs have gone mad. My back door is more than 500 metres from the dredgehole, but I can hear the raucous singing of the frogs at night.
But apparently some snakes have been flushed out of their hibernation. August is way too early to be bumping into snakes. This red bellied black snake was trying to get warm a day after the rain. ( Early Spring weather....torrential rain then sunny days.)

Red bellied black snake trying to warm up, in August!

I went back the next day and it had moved, but not far. Haven't seen it since, but there are plenty of frogs to chase nearby.
