Of course it can be used as an example of evolution, since it is a heritable change in a lineage (I presume that when you say a bird, you are not speaking literally; and would adivse you to cultivate a habit of precision.)
So by precision in language, you are hoping he is talking about a change in beak type among a population of birds over time? That would be evolution. A change to an individual bird over its lifetime is not evolution, I agree. Do you realize that many people are meaning the former when they speak in the latter way? I know that I do if I am not being careful. I am not speaking of an individual bird even though the language may seem to indicate that.
