Just a quick, mostly visual post this time.
This post involves a mistake I never got around to correcting. You may possibly remember a post from several years back in which I mentioned obtaining a pair of tadpoles that metamorphosed into what I thought were kajika frogs.
The first one to morph died soon afterward, but the second is still with us. However, I have consulted several books on the subject and come the the conclusion that it is not a kajika frog but in fact a Japanese brown frog (Rana japonica), or Nihon akagaeru (日本赤蛙) – literally “Japanese red frog” in the local language.
(There is a very slight chance that it the physically similar montane brown frog (Rana ornativentris), but this will require time to get a good look at it – the frog tends to spend a lot of its time hiding.)
You may be wondering why I’m writing about a frog in winter – it should be hibernating, right?
Normally, yes. But frogs will become active even in mid-winter if the weather is warm enough. And December 22nd and 23rd brought us that kind of weather. The forecast for the 22nd – incidentally the last day of term 2 at school – was for temperatures topping out at about 17℃ before moist air brought rain. The warm temperatures didn’t come although the rain did. It rained heavily late in the night – trust me, I was walking through it – through to the early hours of the morning. The 23rd, however, brought that warm change, and the frog became active in the warm (-ish) humid weather.
I might not see this little chap again until spring.
Until next time, stay safe.
