Our only observations were made In Florida about 6 a. m., on April 13, 1924. We had discovered this pair of ivorybills at about the same time the preceding morning when they came out of the cypress swamp and preened their feathers and called a few times from the top of a dead pine before going off together to feed. They had made such a long flight the previous day that we were unable to find them again, but that night, still traveling together, they had returned to the same group of medium-sized cypress trees which they had apparently left in the morning and in which there was one fresh hole in addition to four or five other old ones in the near vicinity. On the morning of the 13th, they called as they left these cypress trees and flew to the top of a dead pine at the edge of the swamp, where they called and preened. Finally the female climbed up directly below the male and when she approached him closely he bent his head downward and clasped bills with her. The next instant they both flew out on to the “burn,” where we followed their feeding operations for about an hour. _Nesting._--As before stated, while there are a few records of February nesting, the most definite records are for March, April, and early May, as follows: April 6, ----.
