Mr. Monk Bumps His Head - S4-E11
Corrected entry: It's late at night when Roger is stung by hundreds of bees at the lookout point. But bees (both the European and Africanized varieties) are not active in late night hours. They're diurnal (active only during the day). Unless something breaks into their hive, which doesn't happen here, they don't fly or swarm at night. (00:42:00)
Mr. Monk Bumps His Head - S4-E11
Corrected entry: Debbie's pet bird is called a parakeet, but it's a much larger exotic bird. It's unlike Monk, whose other OCD eccentricities and obscure knowledge are in full force despite his amnesia, not to know the difference. Monk may not know every rare species by name, but parakeets (aka budgerigars) are household pets common enough that anyone would know Debbie's bird isn't one. Monk definitely would have known.
Correction: The term parakeet is used to describe any small-medium parrot species, like Debbie's bird, not just the commonly owned household budgerigar. Monk's identification was correct.
Correction: Maybe it is early in the morning and did he not drop the waitress's body down lookout point? Also the body could very well have triggered the bees and the hornets.
