3.3.Warembourg Open Space Warembourg Open Space is located north of and connects to Daughenbaugh Open Space (Figure 2). It is characterized by a sea of smooth brome similar to what is shown in Photo 1, with a small pond/wetland on the north side of the Open Space and the Warembourg Fishing Pond on the south end. Some trees occur along these features which provide some structural diversity; however, most of the trees near the Warembourg Fishing Pond are the non-native Russian olive (Elaeagnus angustifolia). Nearby homes offer habitat for species commonly found near homes. 4. Results On both June 20 and 22 environmental conditions were optimal for conducting avian surveys. The reported temperature at 0530 hours on June 20 was approximately 62°F with wind speeds between 0-4 miles per hour (mph) and visibility of 10 miles. On June 22 it was approximately 75° F with wind speeds between 0-7 mph and visibility of 10 miles. Both mornings were quiet with little traffic noise or other noises because of the early start time. Copies of the original data sheets are provided in Appendix A. Detection numbers were too low to attempt any type of distance sampling analysis. 4.1. Coyote Run Open Space Coyote Run was surveyed on the morning of June 22, 2017. Table 1 provides the point count station/transect, species, number, and activity when detected. Point Count Station: As I arrived at the point count station, prior to the initiation of the 10 minute survey, a pair of Red-tailed Hawks flushed from one of the large plains cottonwood trees northeast of the survey point and flew to the east. Based on their behavior, it is likely that they are nesting in one of the nearby cottonwood trees. The presence of the wetland area provided more diversity and most of the detections occurred in the wetland or associated wet areas. Seven species were detected; he dominant species was the Red -winged Blackbird (Agelaius phoeniceus). Several males were detected aurally and visually and it is likely that each of these males is associated with a nest. Nearby houses were within the 150 meter survey distance and two species, the House Wren (Troglodytes aedon) and the non-native and invasive Eurasian Collared Dove (Streptopelia decaocto) both were seen or heard at these homes. COY01: Coyote Run transect 01 (COY01) runs from east to west and is located on the west side of the Open Space. It is located between two housing developments to the north and south, both of which are within 150 meters of the transect. Habitat around the transect is dominated by dense smooth brome with a few small trees and wetlands associated with a small ditch that runs north of and parallel to the transect. Three species were detected. Small wetlands associated with the ditch provided nesting structure for Red -winged Blackbirds, the dominant species observed. No species were detected in the areas with smooth brome and Eurasian Collared Doves and House Finches (Carpodacus mexicanus) were detected at one residence to the south of the transect. COY02: Coyote Run transect 02 (COY02) runs from north to south and is located on the east side of the Open Space. Houses occur within 70 meters of the east side and the west side is Open Space with no human structures (excluding trails). Smooth brome is still the dominant grass species, but several small swales and low areas contain trees including plains cottonwood, willows, Russian olive, and choke cherry (Prunus virginianus). Some of the low areas showed signs of having standing water earlier in the year and Canada thistle (Cirsium arvense) was present. The homes to the east provide habitat for the Eurasian Collared Dove, House Finch, and House Wren. Seventeen individuals representing 10 species were 7 14
