Top-ranked Novak Djokovic edged Gael Monfils 6-2, 6-7 (4), 7-6 (2) on Wednesday in the second round of the Rogers Cup.

The Audubon Society wants bird lovers to contribute research to a project scientists hope will help save Atlantic puffins from starvation in Maine.

Puffins are on the state's threatened species list.
