Eastern Bluebirds also like to sit on the branch over the pond.
Many flying creatures use this branch as a place to spot a prey item to eat, or a place to rest, or a place to socialize.
In this photo, after some rain, the rock behind the Bluebirds is under water. It is our gauge for the water level in the pond.
Below, a turtle sits on the same rock on a day when the water level is lower.
