1943 March 11. Cloudy, warm. I have heard no winter Wrens since Jan. 1 but one sang repeatedly below the east pool. After 7 p.m. I heard three sing again. In a.m. he gave also a rattle - quite loud that I do not remember having heard. When we walked down to dinner at The W.T.E. there was a pair of titmouses just below the stadium, in the Hawthorne hedge, male singing, female giving a soft single note. A Hairy Woodpecker in a locust tree at end of Piedmont Ave., a Sparrow Hawk calling. After dinner we walked up the road to the Stadium Runway. Many Robins singing and feeding in olive tree at Bowles Hall. Swail picked up olives on the ground and ate them. Accipiter Hawk over Stadium. > Mar. 12. Cloudy.
