yes they are still gulls though arent they....and salamanders
and thats not right before my eyes
They're still gulls yes, but that doesn't negate the fact that in the here and now, we have an observable process that has resulted in two different species. That is speciation - one pivotal facet of the evolutionary process. In the small time frame you were asking for evidence, thats all one can really expect to see. Anyone could confirm ring species by going to the spots their found.
If you're asking for macro-evolutionary changes before your eyes, then like Abbadon so nicely put it, you're asking to be shown something in a sliver of the time span thats required - like asking to see the development of a fertilized ovum into a fully gestated human baby in only a day or two.
If you're keen on experiments that can be done in the comfort of one's own lab, I suggest reading about Richard Lenski's work on E.Coli and changing environments. Mind you thats not about showing speciation, but adaptation - another important facet of the evolutionary process.
So there are two empirically observable facets of the theory, making it hard to deny its plausibility over large spans of time.
