On 15 August 2014, at 16:25 MDT, PH noticed an American Crow

A Bonferroni correction was applied to each p value, according to the number of comparisons (corrected p value of 0.05/10 = 0.005 for carrion crow peak viremia and organs of carrion crows euthanized on day 4; corrected p value of 0.05/6 = 0.008 for American crow
peak viremia and organs of carrion crows euthanized due to illness).

The positive and negative predictive values of pelican WNV-associated deaths for human WNND cases were similar in magnitude to those of American crow
(Corvus brachyrhynchos) deaths.
Two field studies of the American crow
estimated local losses in New York and Oklahoma last year at 30 percent and 50 percent, respectively.
In New York, an epizootic of American crow
(Corvus brachyrhynchos) deaths from West Nile virus (WNV) infection occurred during winter 2004-2005, a cold season when mosquitoes are not active.
