A card comes from the Texas coast: the last wild flock of whooping cranes is leaving its marsh, and some of the young are thin. Mateo knows how to help. Find the birds, watch every one, find the one in trouble. He has one day with the refuge boat, and a winter norther on the way.

About the Green Guardians series
Green Guardians is a series of illustrated adventures for readers aged ten to twelve about conservation and looking after the living world. Ava, who organises everything, and Mateo, who can read a track in the mud, belong to a quiet network of young rangers run by Ranger June, and answer real requests for help from scientists and communities. Each book delivers one conservation topic through a real place and a real problem, and shows how things are connected.
