Here they come! Rufous Hummingbirds, Black-chins, Broad-bills, Ruby-throats like this one, and others are migrating north after a hot, dry winter in sunny Mexico or Central America. And they’re ready for a drink. You can help these thirsty birds by hanging a hummingbird feeder filled with the right kind of nectar. Select a feeder that you can easily clean on the inside, and one that has plenty of red to attract the birds. Then fill it with sugar water made by dissolving one part sugar in four parts water (use plain table sugar — no honey or sugar substitutes allowed). And please — no red food coloring!
