Two small lakes between Gallup and Rock Springs had no marsh birds on them and were devoid of all aquatic vegetation.

Annotated List of Birds.

Adults were seen feeding these birds calling them up across the water and placing the food in the bills of the young. The young dove when I cam too near but I was able
