Flying Y over X over Teakettle

‘He will fly a monotonic logarithmic function,’
said the jackdaw on my left. The others laughed.
‘Before he takes off, better give him unction,’
said another. With a swooping flight she graphed
the dizzy fall she estimates I’ll fly
should I leave this roof where we are congregating.
At a signal that I miss, they swarm on high.
They look back to watch me follow. They’re still waiting.
