Martin or Robin Fowler? (7)
I believe the answer is:
birdman
This clue could be a double definition.
'martin' is the first definition.
Both the definition and answer are singular nouns.
Maybe they are linked in a way I don't understand?
'robin fowler?' is the second definition.
The definition suggests a singular noun which matches the answer.
'or' is the link.
Can you help me to learn more?
(Other definitions for birdman that I've seen before include "- - of Alcatraz (film)" , "Ornithologist (of Alcatraz?)" .)
