Big Dry Creek Reservoir

Ownership: 
Private
Colony: 
Yes
Stored Grains Present: 
No
Primary Substrate: 
stinging nettle (Urtica dioica)
Secondary Substrate: 
milk thistle (Silybum marianum)

From Sheppard Avenue in Clovis, drive north on N DeWolf Ave to the creek crossing. If the colony is planning to nest, it will be on the west side of the road, probably 300-800 meters from the road along the stream. In 2015, the stream was completely dry. I do not know who owns the land, but I presume it is private. I'm not certain about the ID of the plants that the bulk of the colony was using because they were too far away, but I could see stinging nettle and milk thistle that the closest birds were perching on. The vegetation height was probably 2-4 feet, but again, it was tough to be certain because of the distance. I first observed these birds in March, so it is too early to be certain that this is actually a breeding colony.
