Several birds do this, one of which is the wren.
Your question needs to also mention the colors of the bird in order for anyone to recognize the species.
I believe that the Common Grackle (Quiscalus quiscula) has vertical tail feathers like a rudder
A wren
A fantail.
because he sees something.
A pugs tail is never straight. A pug's tail is always curled because of its height.So You dont need to worry about curling your pug's tail
A warthog runs with its tail sticking straight up.A long tailed animal that may also hold its tail vertically as it runs is the coati. See 10 seconds into the video.
About as straight as a roundabout
Pony tail, curled, straight, crimped, bun.
no, generally a long straight tail
one has a curly tail and the other has a straight tail
A coyote.
If a pig's tail was straight it would be long so yes.
I've had six dogs, and I find that if the the dog's back is arched upwards when they are standing it means they are either bloated, sick, or about to puke. Standing straight up panting is in pleasure, (with ears up). Standing up straight with slowly wagging or not moving tail with ears up, is looking with interest (when they are curious). Tail between the legs is scared (with ears back.) Ears back while standing up straight is when they feel threatened (w/ tail up, not moving), also barking or growling is an obvious sign. Tail between the legs with ears back, and constant recoiling is feeling nervousness and scared. If a dog is laying down on its side with its stomach exposed is when they are being submissive (and/or rolling on their back).
A dog's tail may be sideways because it did not grow straight. If the dog is in pain, consult a vet regarding the tail.
I'm sure glad to see you, old chum
