It OP. IX. 



Oil April 21st, 1902, a Robiu's nest was found ou the rail of a fence, 

 about four feet from the ground. The nest was made of roots, dry 

 twigs, dry grass, plastered together and to the fen'ce with clay. Softer 

 grass was used in the center. Two l)lue-green eggs were in the nest, 

 their small ends toward the center of the nest. On the 23d the bird 

 was on the nest when 1 made my round, but she fleAV off. There were 

 four eggs in the nest, and just as soon as I left she flew back. On 

 the 30th the nest was found to have been toi-u from the fence and 

 thrown upon the ground. The eggs were broken. No l)irds were no- 

 ticed near this place again. 



On April 14th I found an unfinished nest in a tree. It was being 

 constructed like the one above described. Birds working hard. April 

 17th the nest was completed, but the birds were not near. April 21st 

 I found one blue-green egg in the nest. April 23d I found that three 

 eggs had been laid but had been broken, and the shells were on the 

 ground near and far. The nest was wet with the white of the egg, 

 and the inside of the nest destroyed. I was unable to find the cause 

 of the nest being destroyed. Notliing further was done on this nest 

 by the birds up to the end of the observations. 



On April ITth I found a nest in a tree which had been completed. 

 The Blue Jays and the Robins were fighting, the latter being driven 

 away. On April 2od I found a Robin on the nest sitting ou one 

 egg. April 30th I found the bird sitting on three eggs. The Robin 

 seemed qtiite friendly, for she allowed me to come very near to her. 

 Then she flew only after 1 made a motion as though to touch her. 

 May 2d I found the bird sitting on four eggs. May 5th the Robin 

 was still on the nest. She allowed me to come quite near. Jlay 

 7th, two little Robins in the nest; the other two eggs were pipped. 

 May 9th, four little birds. They seemed all mouths and eyes. The 

 mother flew as soon as I came near the nest, but did not go more 

 than five feet. The male followed me a long distance. This was the 

 first time he had shown fight. On March 14th, the birds have grown 

 very much. They would not take anything from me. Both the old 

 birds tried to fight, and as I left the nest the male followed. May 

 16th the birds were nearly feathered; very shy. May 17th, all the
