Hi, Rusty!
Uhm.....I wondered for a moment whether a "murmuration" might also mean an incantation......you know, like such as might be uttered by the three witches...!
But decided that justice might indeed be best served by a clutter of starlings!
(apparently an alternative term for "murmuration of....")
Yes, I thought the Times Cryptic was a good one, again - I am having(for me) an unusually successful week!
Only two left that I couldn't parse......
6a. Cycle material primarily on side facing leader (5)
moped = cycle (def)
m - m (aterial)
maybe "ed" meaning "editorial" (leader)?
I'm not sure where to go with this?
16d: One taking off, or opening up, in a way (9)
aeroplane = one taking off?
I can't account for the rest of the clue!
Which was the one you yourself had difficulty parsing?
