National Wildlife Federation Wildbird Postcard Series 502:2 RUBY CROWNED KINGLET (Regulus calendula calendula) Royal in name and nature, he is one of our smallest perching birds. During migration, he may be found throughout the United States. At all other times he prefers to keep strictly to himself in the mountains and forests. He is a valuable asset for his skill at plucking leaf bugs and spiders from the trees. Copyright 1945 National Wildlife Federation, Washington, D. C. NAME. CITY HERE
