Probably, if you are taking a picture at night or in very dim light as would normally be the case for owls I presume. Birds have an iris that responds like ours does so you could temporarily blind the bird and startle them at the same time. Look at point #3 from the following link: photo.net/learn/nature/owlflash.
I did a web search and apparently use of a flash is not uncommon for daytime pictures. For instance, if the sun is in the wrong direction it helps to get rid of shadows. Various web-links indicate that some birds will spook and fly away on the first flash while others seem not to care as much.
Personally, I think that the bird's well-being should be more important that getting that perfect shot so I cannot think of any situation where I would want to use a flash. I would put it into the same category as using bird recordings to attract birds. During breeding season or anytime that the birds well-being is at risk, definitely not a good idea. Other times, I would reserve judgement.
