 Peter says: "This image was taken in January 2001. This bird had obviously undergone some sort of stress during the breeding season. We caught a large number of graellsii during January 2001, many showing fault baring in the primaries, but not so extreme as in this sample. Either there was a shortage of food near breeding grounds, or possibly sickness (botulism) may have been responsible. There was much botulism around in the previous year, and some birds do survive the effects. But most perish."
