She says that shows some of the birds are sticking around.Cancilla ran tests Thursday on four 29-day old chicks in the Peregrine nest in Cedar Rapids. They also marked the chicks to keep track of them.She says they’re building a genetic profile of the birds in Iowa and surrounding states.Cancilla says it doesn’t appear the birds in Lansing have any eggs or chicks.
