Gosh, is that a bird call? (3)
I believe the answer is:
coo
This clue might be a double definition.
'gosh is that a bird' is the first definition.
'coo' can be an answer for 'gosh'. I'm not sure about the rest of the definition.
'call?' is the second definition.
(I have seen 'Call of dove ' mean 'coo' so perhaps 'call' could also mean 'coo')
Can you help me to learn more?
(Other definitions for coo that I've seen before include "Sound made by doves" , "Softly say" , "Call like a dove" , "(Of pigeon) murmur" , "well I never!" .)
