Probability of Presence Summary <br />The graphs below provide our best understanding of when birds of concern are most likely <br />to be present in your project area. This information can be used to tailor and schedule your <br />project activities to avoid or minimize impacts to birds. Please make sure you read and <br />understand the FAQ "Proper Interpretation and Use of Your Migratory Bird Report" before <br />using or attempting to interpret this report. <br />Probability of Presence () <br />Each green bar represents the bird's relative probability of presence in the 10km grid cell(s) <br />your project overlaps during a particular week of the year. (A year is represented as 12 4- <br />week months.) A taller bar indicates a higher probability of species presence. The survey <br />eort (see below) can be used to establish a level of condence in the presence score. One <br />can have higher condence in the presence score if the corresponding survey eort is also <br />high. <br />How is the probability of presence score calculated? The calculation is done in three steps: <br />Franklin's Gull Leucophaeus pipixcan <br />This is a Bird of Conservation Concern (BCC) throughout its <br />range in the continental USA and Alaska. <br />Breeds May 1 to Jul 31 <br />Golden Eagle Aquila chrysaetos <br />This is not a Bird of Conservation Concern (BCC) in this area, <br />but warrants attention because of the Eagle Act or for potential <br />susceptibilities in oshore areas from certain types of <br />development or activities. <br />https://ecos.fws.gov/ecp/species/1680 <br />Breeds Jan 1 to Aug 31 <br />Lesser Yellowlegs Tringa avipes <br />This is a Bird of Conservation Concern (BCC) throughout its <br />range in the continental USA and Alaska. <br />https://ecos.fws.gov/ecp/species/9679 <br />Breeds elsewhere <br />Western Grebe aechmophorus occidentalis <br />This is a Bird of Conservation Concern (BCC) throughout its <br />range in the continental USA and Alaska. <br />https://ecos.fws.gov/ecp/species/6743 <br />Breeds Jun 1 to Aug 31 <br />Willet Tringa semipalmata <br />This is a Bird of Conservation Concern (BCC) throughout its <br />range in the continental USA and Alaska. <br />Breeds Apr 20 to Aug 5
