For the Northern Cardinal and
House Finch there was no significant difference in the mean body weights of those infected compared to those that were not (t = 0.07, P > 0.05 and t = 1.47, P > 0.05, respectively), however, in the House Sparrow, infected individuals had a higher mean body weight (t = 2.71, P < 0.01)(Table 2).
Therefore, I monitored the portion of postn atal growth of
