Calls can be broadcast from a "boom box ", a portable CD or cassette player, or an mp3 <br />player attached to amplified speakers. Calls should be broadcast loudly but without <br />distortion. <br />Recordings of this survey sequence (compact disc or mp3 sent via email) are available free <br />of charge by contacting: <br />David Klute <br />Bird Conservation Coordinator <br />Colorado Division of Wildlife <br />6060 Broadway <br />Denver, CO 80216 <br />Phone: 303 - 291 -7320 <br />Email: David.Klute @state.co.us <br />Identification <br />Adult burrowing owls are small, approximately 9 -11 inches. 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 />http: // wildlife. state .co.uslWildlifeSr)ecies /Profrles /Birds /BurrowingOwl. htm <br />Additional identification tips and information are available from the U.S. Geological Survey <br />Patuxent Wildlife Research Center website: <br />http: //www. mbr- pwrc .usgs.aov /id /framist/i3780id. html <br />What To Do If Burrowing Owls 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. Comparison of detection probability associated with <br />Burrowing Owl survey methods.
