Figure 4.

List $L_2$: ranked list (n = 23) of bird species found from analysis of Culex pipiens–restuans (CPR) blood meals. Left panel: Relative abundance ($n\times a_s$ ) of bird species and relative feeding (fraction of CPR blood meals) ($n\times f_s$ ). Dashed vertical lines at relative abundance and feeding “1” represent the ratio “1/n” where n = 23 is the bird species diversity. Right panel: relative host preference ($n\times p_s$ ) of CPR. Quoted letters “M” and “R” stand for migratory and resident birds, respectively.
