We're talking about birds portending human death. The author even suggested a likely explanation for how the old wives tale started (animals being attracted to run down places because the building's owner is being cared for elsewhere), which would seem to indicate they don't actually believe birds can tell when someone is going to die. I don't think this situation qualifies as "Spidey sense".
