Table 1.

Sample sizes of greater snow geese captured during spring staging, 2007–2009. (Captured groups were assigned as follows: control (mark and release immediately after capture), or kept from 2 to 4 days with ad libitum food (fed treatment) or without food (fasting treatment). The number of females resighted during the following autumn is split among the total resighted and those for which the family status was ascertained.)
