I am not a birder, as stated before, but like a lot of photographers with a big lens at hand, birding calls as the occasion arises.
On a recent school camp, I had a lot of time on the beach waiting for things to happen out on the water, so birds became my distraction. I did not set any special settings (I have a 1x4 and 5x1 config set in the EM1x, but this was the EM1 mk 2), just pointed and shot.
My first subjects were seagulls floating on the fairly strong breeze, so not too hard.
I had plenty of time to practice as the kids paddled against a strong current to a small island off shore and back again. I was pretty happy with the results and with a little confidence and luck I started to assume rather than hope.
One thing I really enjoy with my current job is the variety it offers and there is no doubt I am more confident trying almost any type of imaging. My day may comprise of a quick student portrait, then a group, maybe studio ID shot, class sit in, sport (any type), promo image for an event and then a ball that evening (and has). This requires not only a lot of gear and familiarity with it, but the ability to don a different creative hat and wear it confidently.
Success at a little impromptu birding is a happy side effect of becoming a generally more capable photographer who is growing into various roles.
