To ensure a safe bird-feeding environment, change hummingbird nectar every three days.. Like the other birds, the hawk is coming to your yard because there is a source of food. If you want to discourage the hawk, you'll have to take your feeders down for a few days to disperse the hawkâs food source--smaller birds.
