Clue: Bird, dogs and parasite found in wood in Manhattan? (8,5)
Answer: COCKTAIL STICK
Explanation: Definition: wood in Manhattan
A charade of COCK ('bird') plus TAILS ('dogs', verb, in the sense of follows) plus TICK ('parasite'); a Manhattan being a drink, although the maraschino cherry with which it is often served generally has its own stalk, rather than a stick.
