Some hand tools found under the scared birds (13)
I believe the answer is:
yellowhammers
'birds' is the definition.
(yellowhammer is a kind of bird)
'some hand tools found under the scared' is the wordplay.
'some hand tools' becomes 'hammers' (hammer is a kind of hand tool).
'found under' means one lot of letters go next to another.
'the scared' becomes 'yellow' (I can't justify this - if you can you should give a lot more credence to this answer).
'hammers' put after 'yellow' is 'YELLOWHAMMERS'.
Can you help me to learn more?
(Another definition for yellowhammers that I've seen is " Birds".)
