I think I have about 5 or 6 memory cards laying around. I take it out and put a new one inside. Since there wasnt any too important pictures on it, I forgot about it 😀.
Taking shots of birds is quite a trial and error. I did have 5 photos of this flock of birds but ended up deleting them and only kept these two you see here. Usually yeah, when the flock gets airborne, you only have 2 or 3 seconds to take a shot.
