As said, a small bird at below flying speed will rarely do any serious damage, if it hits on landing then do a good inspection to check it did not enter an intake or cuase any damage, on take off then a precautionary circuit to land before carrying out a similar inspection unless of course you can see where it hit anyway, certainly do not try excessive manouvres or braking to avoid or you could make the situation even worse! I have had a few bird strikes in my time, my first was in a Swedish airforce equivalent to a Jet Provost, this hit right on the windscreen at cruise speed, caused a lot of mess bit no real damage, my latest was believed to be a Swan through an A330 engine on TO - that was a totally different story!
