Table 2. A list of bird species fatally striking the windows at CAS.
Probability of n strikes is the cumulative binomial probability of n strikes, which indicates if birds are over-represented in window strike data (P<0.05) or under-represented (P>0.95). Some birds that did not fatally strike were included if they were very common in area surveys, and they were significantly under-represented in the strike data (P>0.95). Four species of birds struck the windows, but were never fatally injured (Buteo jamaicensis, Accipiter cooperii, Charadrius vociferus, and Troglodytes pacificus.) See supplemental materials for more information.
