I have seen that but very few times, only one or two birds and not far from water. Chris says “may be many kms from river/lagoon”. My question is: When it comes time to arrive or leave, do they fly in or out from the land surface or do they need to walk to or from the water to get there or leave there. Surely at best they would find it hard to start or end a flight on land, not water.
