Provocation can be a relevant factor in a court's assessment of a defendant's mens rea, intention, or state of mind, at the time of an act of which the defendant is accused.
Best Plants to Attract Hummingbirds. Hummingbird flowers evolved at the same time as hummingbirds, developing specific features that don't allow access to other birds. The best flowers are tubular, scentless, brightly colored (often red, orange, or blue), and grow where it's easy for the birds to hover and sip.
Wasps, hornets, and yellow jackets are more likely to be attracted to a hummingbird feeder with old nectar in it. Another option is to get a hummingbird feeder with bee guards built in. The hummingbird can reach through to drink nectar, but the bees cannot.
