We have a theory... For over 2 years, the general population has been mostly absent or greatly reduced, due to the extended lockdowns in response to COVID. Closed restaurants and other businesses meant less easily available food in  trash bins, so the animals slowly moved into more populated neighbourhoods. During those months of lockdowns, residents may have also taken comfort in watching and feeding wildlife. With life returning to more normal activities, Coyotes are suddenly finding themselves pushed out of cushy territories, that had been their home for some time. So, we believe that the current attacks on residents are a combination of territorial aggression and a demand for food.
