Eastern grey kangaroos don't like rain.
They don't seem to enjoy getting wet, but the real problem is that the rain makes it harder for them to hear and see predators on the move. Poor Merrilyn, as if she hasn't had enough of late.
In many ways it is worst for the "at heel" joeys. Once they reach a certain age and aren't on milk anymore, then their mothers will not allow them to be too close. What this means in rain is, the mother finds a relatively dry spot under a tree or bush, but won't let the joey too close, so they end up standing in the full rain as they don't want to be too far away. Here's Tomasina, Merrilyn's older "at heel" joey.
These heavy downpours affect other animals here too. I think this bird is a young little wattle bird, but didn't want to frighten him from his position. He had discovered the back of my patio furniture and was trying to dry out. Looking at the tail, I wonder if something has attacked him. I watch the wind and the very heavy rain and wonder how birds hang on at all.
And here's a tiny mouse caught up in the flood waters.
Can't see him? This might help.
