815 + Madam Puffin Keeps a Clocklike Schedule At a definite time each spring, puffins give up their carefree lives at sea and nest on islands from Maine to Greenland and from Por tugal to Norway. They dig bur rows, carpet them with straw pal lets, and lay single large eggs. On certain English islands they invade rabbit warrens, driving out the rightful tenants or living with them. This moon-faced mother dug her home beneath a Labrador boulder. Mrs. Starling Is Wife Number 3 Female starlings, normally mo nogamous, may dwell in harems if they exceed the sex ratio or if a lone male controls a very desirable territory. This bird shared her mate with two other tenants in the author's bird boxes. The Old World's starlings were introduced into New York in 1890. For 20 years they remained close by. Then they spread rapidly, settling as far away as Hudson Bay, the Pacific, and Mexico. Though they devour wireworms and Japa nese beetles, they remain unpopular with cherry growers. Cities dislike their chatter and dirt; the National Capital tried in vain to evict them.
