Helicopter flight surveys: The primary purpose of daily water flights is to collect information on presence or absence of birds on the water and acquire general locations for the birds. Field work was conducted by SFUMMRG researchers. These flights ranged in altitude from 300m in poor conditions to 1500m in good conditions. Field trials indicated detection distance in good conditions was a minimum of 5km. Methods: When a radio is detected, switch the cable switchbox between left and right to determine which antennae has the strongest signal. Record the signal strength (on a scale of 1-5, 5 being the strongest) and estimated location of the bird (georephranced to a landmark). If you are reasonably certain that the bird is on the water (the signal strength should be 3 or greater most of the time) delete the frequency from the bank. If it is not too time consuming, enter the elevation for each detection. For data entry, enter your best location. Nest search flights: Searched inland for nesting sites of birds not present on the ocean. Flights ranged from 1500-3000 m in altitude, and detection distances in good weather exceeded 10 km. These flights were less efficient in detecting multiple birds, since we located radioed murrelets nesting up to 54 km from their capture location (Huettmann et al., in review). When an inland signal was detected, the location of the signal was determined to an area ~100 x 100 m in size. The goal was to get to the stage where the helicopter was hovering directly facing the slope and have a booming signal which is equally strong on both antennas. Where possible, ground based telemetry was subsequently used to locate the nest tree in which the radio-tagged bird was incubating. However, some nests were inaccessible from the ground, being located in or adjacent to exceptionally steep or dangerous terrain, or too remote from suitable helicopter landing locations. Only ground truthed nests are included in nest location datasets. It includes the following attributes: Date: the flight date, in format yyyy-MM-dd Study Site: the study region (DS = Desolation Sound) Time Up: the flight start time, in format HH:mm, local time Time Down: the flight end time, in format HH:mm, local time Total Air Time: the flight duration, in minutes GPS track file: the name of the file containing the GPS track for the flight Max Search Altitude (ft): the maximum flight altitude, in feet Av.
