Ulcerative Enteritis in the Pheasant, Blue Grouse and California Quail

Abstract

with a %7/-inch iron and rams with a 2-inch iron. The plastic streamer was inserted in a small slit in the left ear and secured with a jess knot (Craighead and Stockstadt, ibid.). The stock-type tag was clamped in the right ear of the animal. Sheep numbered 1 to 5 were not marked with the plastic streamer and have consequently been more difficult to locate. They have been seen and identified again only because groups of sheep were thoroughly scanned with a 30X spotting scope. On the other hand, 25 animals with the plastic streamer have been spotted at a, great distance, both with the naked eye and with field glasses. They were then carefully stalked until the brand could be read. Several observations of marked animals have also been made when the sheep took flight. Although it was impossible to read the brand, the streamer provided a record of movement from the trap site, as a different colored plastic streamer was used at each trap. The only change we contemplate in the above will be to outline the brand with paint so that the number can be more easily read. Some of the 25 sheep have been ear-tagged for over a year, and to date only one streamer has pulled loose. This one was put on by an inexperienced helper, and the ear slit was not properly made.
