hour, the male put his head out of the nest (4.10) and looked at me 

 for seven minutes. When he flew away at 4.17 he must have 

 found his mate, for in three minutes she came to the nest with a 

 little cry. She brooded the young birds for thirty-nine minutes 

 (4.59), then after looking out several times, flew away (5.01). 

 At 5.07 the male came to the orchard, and a little later went into 

 the nest (5.14). 



June 29, 3.40 to 4.58 p. m. — The male was in the nest when I 

 reached my place of observation, and twenty-four minutes later 

 (4.04) flew out and away. The female came to the nest three 

 minutes afterward (4.07). I did not see her coming and I heard 

 no sound until she struck the trunk of the tree. After brooding 

 her young for sixteen minutes she put her head out, with her 

 mouth open (4.23). It must have been very hot in the nest, for 

 the day was a warm one. Four minutes later (4.27) she flew 

 away, but returned at 4.53 and went at once to the nest. I did 

 not see the male after he left the nest at 4.04. 



June 30, 3.40 to 5.26 p. m. — I changed my position to one 

 seventy-five feet away, but in front of the nest. The male flew 

 about, but would not go to the tree. In twenty minutes (4 p. m.) 

 the female came to the next tree, four minutes later to the back of 

 the nesting tree, crept around it and went into the nest. In 

 seven minutes, she flew away (4. n). It was very warm, and I 

 opened my umbrella just after the female had flown. I kept it 

 up forty-six minutes, but neither bird came. At length I 

 closed my umbrella and in eleven minutes (5.08) the female came 

 to the nest and went in. She stayed but a moment, then flew 

 away. The male was not in sight for an hour and twenty- 

 nine minutes. 



July 1, 3.35 to 5.13 p. m. — The male flew away from the nest as 

 I approached. Eight minutes later, the female came with a 

 little cry and remained in the nest for four minutes, then flew 

 away (3.47). She returned at 4.20, and stayed but a moment. 

 Three minutes after she disappeared, the male came to a nearby 

 tree where he remained absolutely motionless and flat against a 

 large limb, with another between us, for forty-four minutes, or 

 until 5.08 when he gave his "wick" cry several times, as the 

 female approached. She paid no attention to him, but went 

 directly to the nest (5.10) where she remained two minutes. 

 Then the male went to the nest, but came out at once and flew 

 away.
