Stealthily approaches the long-legged wading birds I hear (6)
I believe the answer is:
stalks
'stealthily approaches' is the definition.
The answer and definition can be both to do with motion as well as being verbs in their -s form.
Perhaps they are linked in a way I don't understand?
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for stalks that I've seen before include "Follows a prey stealthily" , "Hunts" , "Pursues stealthily, game or person" , "Follows stealthily with evil intent" , "Main stems of plants" .)
