What are three ways that the kids try and get peoples' attention about the bridge?

Jose, Molly, Maria, and Hughie noticed falcons on the bridge and they go to the bridge with Leon. Joe tells Leon and the kids to get off the bridge while it is under construction, so the kids decide to have a meeting about what is going on. They know all about falcons, thanks to Jon and Susan Woods.

The kids band together to picket the construction job, holding up signs in support of nesting falcons. When Joe tells the kids to leave or they’ll be arrested. Leon arrives and directs them into town, where they are filmed and interviewed by a TV news crew.
