They are brown with white spotting <br />and white barring on the chest They have long legs in comparison to other owls and are <br />frequently seen perching on prairie dog mounds or other suitable perches (e.g., fence posts, utility <br />poles) near prairie dog towns.. Juvenile burrowing owls are similar to adults but smaller, with a <br />white/buff colored chest that lacks barring <br />General information about burrowing owls is available from the Colorado Division of Wildlife <br />website: <br />htto://wild life.state.co.us/WildlifeSoecies/ProfilesBirds/BurrowinpOwl.htm <br />Additional identification tips and information are available from the U.S. Geological Survey <br />o F r ~nn.~rr a earr#6enter vvebSitR' <br />htto:/lvrww. mbr-owrc.usgs.gov/id/framistfi3780id. html <br />What To Do If Burrowing thvls Are Present <br />If burrowing owls are confirmed to be present in a prairie dog town, there are two options before <br />proceeding with planned activities: <br />1, Wait to initiate activities until after November 1 st or until it can be confirmed that the owls <br />have left the prairie dog town. <br />2. Carefully monitor the activities of the owls, noting and marking which burrows they are <br />using. This is not easy to accomplish and will require considerable time, as the owls may <br />use several burrows in a prairie dog town. When all active burrowing owl burrows have <br />been located and marked, activity can proceed in areas greater than 150 feet from the <br />burrows with little danger to the owls.. Activity closer than 150 feet may endanger the owls. <br />Reference <br />Conway, C. J. and J. C.. Simon. 2003.
