The newest chicks in town are the sandhill babes, over at the Tracy Aviary. While the birds aren't considered an endangered species, the young pair is the first set of sandhill crane chicks hatched in captivity in Utah. Grenville Roles, curator at the aviary, said the birds hatched last Thursday and are gawky and delightful to watch. "They're balls of rusty fluff on long legs. They look like old Brillo pads," Roles said. The parents, Mr. and Mrs. Sandhill Crane, originally of Randolph, in Rich County, have been at the aviary without a delivery for 13 years, so officials are delighted by the addition - even if they did help by way of artificial insemination. The birds will mature in about three years and could live as long as 30 years.
