Bulletin A^o. 27. 57 



Killdeer was not actually recorded at LaCrescent, Minn, until April 2. 

 Meadowiark followed three days later and Bronzed Grackle a week later. 

 The same species reached northern Ohio a day earlier than northern 

 Illinois, and the Killdeer and Robin were seen at Pontiac, Mich., on 

 March 9 and 8 respectively, but Bluebird on the 17th. In northern Ohio 

 Meadowiark and Bronzed Grackle preceded the others by one day, but 

 accompanied Bluebird into Michigan. 



The reports from the extreme east must be given in detail because 

 they are too scattering to be correlated, probably on account of the 

 differences in longitude, therefore representing two streams of migration. 



Killdeer reached Berwyn, Pa., on March 17. There are no other 

 reports on this species. 



Meadowiark passed the winter at Philadelphia and Berwyn, Pa. It 

 reached Portland, Conn, on March 9. 



Purple Grackle reached Berwyn, Pa., on February 10 and Philadelphia 

 on the 13th. Bronzed Grackle reached Portland, Conn. March 8. 



The Robin was first seen on February 12 at Philadelphia ; March 8 at 

 Berwyn, Pa. ; March 14 at Portland, Conn. ; March 19 at Hanover, N. H. 



Bluebird first appeared on February 5 at Berwyn, Pa. ; March 11 at 

 Hanover, N. H. ; March 18 at Portland, Conn. 



The data for a single year taken by itself throws little light upon the 

 movements of these species in relation to each other, but the tendencies 

 are at least suggested. Under especially favorable conditions all five 

 species may migrate on the same day whether early or late, especially 

 north of the winter range of all. But there is always the greater 

 probability of seeing the Bluebird and Robin first, closely followed by 

 the Meadowiark and Grackle, and lastly by the Killdeer. 



A DOWNY woodpecker's NEST THAT 1 DID 

 NOT COLLECT. 



One morning last spring, while collecting botanical specimens, I 

 accidentally frightened a Downy Woodpecker from its hole. As the 

 hole was too deep for me to tell what was in it, I returned with a saw 

 and chisel in the evening, expecting to get a set of eggs. Approaching 

 quietly, I heard the bird in the hole hammering away at a great rate. I 

 at once decided the bird had not finished digging its hole, and probably 

 ten days later would be soon enough to laok for a full set of eggs. 



Ten days later I returned and was not a little surprised to hear a hole
