1. Learn about the ruby-throated hummingbird – The Missouri Department of Conservation encourages people to discover nature this spring by learning about the ruby-throated hummingbird. Missourians will begin seeing these birds this month as the tiny long-distance fliers return to the state as part of their spring migration. Like about 80 other bird species that breed in Missouri, hummingbirds typically migrate south in early fall and migrate back north in the spring to nest and raise their young. Hummingbirds are important pollinators for many plants that require a long-billed pollinator. Great native plants for hummingbirds include cardinal flower, jewelweed and trumpet creeper. Hummingbird feeder sugar water does not need to be colored red. The birds will find it and drink it without coloring. Visit Hummingbirds.net/map.html to see when and where hummingbirds are migrating. The migration map shows locations where the birds have already been spotted this year as they migrate northward.
