Map of Grand Forks County showing the route surveyed for Yellow Rails on the night of June 4 and June 5, 2003. With regard to this map, I would note that available habitat for YERA has decreased because of conversion of some sections to cropland through the use of field tiling to remove excess water, and because some sections are now over-run by cattail.

Listening for Yellow Rails by getting out of the car and listening for clicking in a pattern of alternating two and three clicks. This was at the end of a long night in which a total of 100-110 Yellow Rails were heard. I consider numbers conservative estimate of number present. This is the 4th e-bird report for the night of June 4 and 5. See the attached map for the route traveled.
