After our first mature male Ruby-throated Hummingbird arrived on March 31 a second mature male joined him a couple of days later. Today a third mature male arrived about midday and about 10 minutes ago a big female arrived. The males seemed to have some sort of truce as several times they were all on one feeder at the same time but the female has now begun taking over and driving them away. Hummingbirds are a joy to watch. Tommy & Virginia Curtis Smithville, TN DeKalb County
