Crane family at forest

When hiking at summer place, and as coming back there was a bit strange group at forest on that area.
Common crane family was also hiking there. Have seem crane often, one couple lives summer at march next to cabin and other at another lake about half a mile away and others visit the lake often.

But I had never seen then so deep in forest. It was about 400m or more to nearest lake, field or march where they usually spend time.

This is where they usually spend time, but here the young ones stay hiding or usually stay at field close by and adults move between those two places several times during the day.
