I watched part of that showing too. Afterward I looked up some online articles and learned some interesting things I hadn't noticed about The Birds.

For one thing, it broke with the Hitchcockian tradition of strong male leads with generally lesser female roles. In The Birds, the male lead was the weaker character; it was the three main female roles that were the focus.

Another unusual thing: it had no musical score. The only music in the movie was when characters sang or brief snippets of music were heard on the radio.

Of course, the really unique feature was the ambiguous, open ending. In keeping with that, there was no "The End" superimposed over the final frames.
