| On March 7 the Western flock's first family group began their migration! Fifteen whoopers from the new Eastern flock are also migrating, including one first-timer: the new flock's first wild-hatched chick (W601) and her parents. Where are they? Trackers don't know! Viewers
reported Whooping cranes amid large migrating flocks of Sandhill
cranes in Indiana, Illinois, and
Wisconsin
at the end of last week, but which birds were they? We

Tom Stehn's report
"It is not until April when most small groups of whooping cranes will ruffle their feathers one last time, consume a final sip of brackish water, take a few running steps, pump their 7-1⁄2 foot wings and lift off from the salt marsh," writes Tom. But one family left early! Tom names the biggest threat the cranes face as they migrate north, and tells us why he's carefully watching one of the families. More >>
Tom mentioned that the biggest threat faced by migrating cranes is something they can't even see. Texas, the wintering grounds of the Western flock, has a LOT of them. What are they?

Tom's report said most wild cranes start their migration about 10 in the morning. Before you answer today's question, look back for clues, and check out Up Up and Away: Thermals and Updrafts.
