Stinging nettle patch is the nesting substrate, forming a long strip where the toe of the road and the toe of the dam join. The nettle is bordered with milk thistle along the road-side; nettle is bordered by coyote bush and willow on the opposite edge, to the west, closer to the dam. The males were about 80% of the birds seen flying. There were over 800 males and 150 to 250 females. There was no food, nor nesting material, observed being carried by the flying birds.
