Bushy means growing thick and shaggy. Eyebrows, beards and the tails of certain animals.
It describes hair that grows outwards rather than lying flat, which is why bushy eyebrows are so noticeable and why a squirrel's tail is the standard example. Plants get it too, and a bushy plant is dense and well branched rather than leggy, which gardeners encourage by pinching out the tips. Bushy-tailed appears in the phrase bright-eyed and bushy-tailed, meaning alert and eager.
