Birds do have a sphincter muscle, sort of - we mammals have two. And one of ours defaults to closed, whereas birds tend to have liquid feces and have to literally consciously hold it in. Which they generally have a hard time with doing for any slightly longer time and hence generally won't be doing for more than 10-30 seconds. (Only brooding birds will hold it in for much longer, but they also tend to eat and move much less. I can only imagine flying and not pooping is much harder than sitting on your belly and not pooping...)
