A problem with crows

As we move through this pandemic, anything out of the ordinary can be disturbing. I cam across this news feed and had to double check to make sure it was true, before I posted it here. We have to be very careful about spreading rumours and fear in a time when there is so much fake news going around. I am not from Alberta but I have many cousins who live there so I want to make sure they know what is going on and that they be extra careful.
The Royal Canadian Mounted Police in Alberta found over 2,000 dead crows on Alberta highways recently, and there was concern that they may have died from Avian Flu. (This is what we don't want another dangerous flu.) A Pathologist examined the remains of all the crows, and, to everyone's relief, confirmed the problem was NOT Avian Flu. 
The cause of death appeared to be from vehicular impacts. However, during analysis it was noted that varying colours of paints appeared on the ...bird's beaks and claws. By analysing these paint residues it was found that 98% of the crows had been killed by impact with motorbikes, while only 2% were killed by cars.
The RCMP then hired an Ornithological Behaviourist to determine if there was a cause for the disproportionate percentages of motorbike kills versus car kills. The Ornithological Behaviourist quickly concluded that when crows eat road kill, they always have a look-out crow to warn of danger. They discovered that while all the lookout crows could shout "Cah", not a single one could shout "bike"
