Transient is used to describe a situation that lasts only a short time or is constantly changing.
I took this photo earlier this year and hope it represents the word we have been challenged with this week.
These shy (rare breed I think) sheep were quickly moving along a dusty track away from us. They had spotted us before we spotted them.
It was a fleeting glimpse. The adults had unusually long horns giving the whole scene the feeling of an African savannah not heathland in Suffolk, England.
We continued along our separate paths hidden from their view.
I set the camera to full zoom and sneaked through rough ground to try and photograph them while hiding behind a tree. I only managed to get this one of the adult male. If anyone knows what breed of sheep they may be please let me know.
