The most obvious difference between adult beavers and kits when they are in the water, apart from their size, is how they lie in the water. Adult beavers lie low. Little can be seen of them but their heads and shoulders, whereas the kits appear to be much more buoyant. They ride high in the water, so that the whole length of their body is exposed and only the tail and limbs cannot be seen.
Here is an adult beaver swimming.
And here is a kit I saw a couple of days ago and who has already figured on this blog through You Tube.
The members of the Perth Natural Science Society, who came here recently reported that they had seen four different species of damselfly. I was lucky enough to see a dragonfly yesterday afternoon. The battery of my camera had run out, but I had enough time to go back to the house, recharge the battery and find the same species again. I looked for a photograph of the animal and think I found it in 'Dragonflies' by the late Philip Corbet and Stephen Brooks. I think that it is an immature male Black Darter (Sympetrum danae), or a female. The male is much blacker.
Here is a photograph of it.
