An hour or so ago "eagle" decides a cool new spot to perch is on an empty tall glass. He thoroughly enjoyed chirping and leaning into it, enchanted with the new timbre the tall glass provided. Suddenly I realized he was silent and imagine my horror when I glanced over and there he was head first in the glass with his tail feathers protruding unable to make a sound or move with his beak supporting his weight! I immediately tipped him onto my lap and he sat for a moment in shock. Had 5 ml of liquid been in that glass he would have drowned. No better trap exists, he couldn't move a feather. Such are the innumerable risks around the house for a tame budgie. Loving owner's please beware, a tragedy was very, very narrowly avoided.
p.s. he has a black spot on his beak from the L.A. cola stain on the glass bottom, thank god it was empty.
