The refuge begins posting updates once the birds begin arriving (around mid-October) and posts information frequently until the birds leave for their summer home in Canada (near the end of March). Once the birds have left their wintering grounds and the data has been fully analyzed, the refuge prepares the Aransas-Wood Buffalo Whooping Crane Abundance Survey, a full report on the season. This information will also be made available to the public. 

Please be sure to check back to this site for updates and the final report.
