Seasonal breakdown of the frequency of detection for high-risk species. On the y-axis, FOD stands for the frequency of detection, and on the x-axis are the four-letter alpha codes for each species. The blue denotes the per cent frequency of detection in the winter, and the pink denotes the per cent frequency of detection in the spring. For each species, the alpha codes are as follows: BLJA, Blue Jay; CACH, Carolina Chickadee; CARW, Carolina Wren; CHSP, Chipping Sparrow; EAPH, Eastern Phoebe; EATO, Eastern Towhee; HOFI, House Finch; MODO, Mourning Dove; MYWA, Myrtle Warbler; NOCA, Northern Cardinal; SOSP, Song Sparrow; TUTI, Tufted Titmouse; WBNU, White-breasted Nuthatch; WTSP, White-throated Sparrow.
