London - A psychopomp of 'africanised' bees has been spotted swarming outside HM's bedroom window Palace sources reported today.
Hellfire Club soothsayers fear the colony may be gathering in a traditional midwife-to-the-dying rite, sparked by unseasonally high temperatures.
The funerary heralds and their pall-bearer aides were last spotted before the Queen Mother's own RIP.
Thousands of whip-poor-wills - North American nightjars of the Caprimulgus Vociferus genus - 'shat their guts out' all over Clarence House lawns in a bizarre avian karmic ritual.
'Millions' of the nightjars' first cousins - known as chuck-will's-widow (Caprimulgus Carolinensis) - later bombed the Princess Diana Memorial Fountain with gallons of cuckoo spit.
The subsequent clean-up rivalled last year's Gulf of Mexico Deepwater Horizon oil spill remediation.
Last week Palace quacks voiced their fears that a spate of nosebleeds will see HM drop dead before the April 29 royal wedding.
"Kinda ironic!" a Good Friday Agreement source chuckled today.
