Rare Northern Birds near Chicago, 111. — Two miles north of Wauke- 

 gan, 111., is a low barren tract of sand interspersed with low sand hills and 

 ridges and small sloughs, the northern end of which is sparingly planted 

 with white pines, the greater part of which, I learn, were placed there in 

 the early seventies, by Mr. T. H. Douglass of Waukegan. The ground 

 is thickly covered with juniper and cedar. From November 5 to 13, 

 this year (1906) I have observed and taken the following birds: 



Penthestes hudsonicus hudsonicus. Three specimens seen, two taken. 



Spinus pinus. Several large flocks seen, eight taken. 



Acanthis linaria linaria. Two large flocks seen, twelve taken. 



Pinicola enucleator leucura. Two seen, two taken. At Lake Forest, 111., 

 a flock of six have been feeding on the box-elder trees. 



Loxia curvirostra minor. Two or three small flocks have been seen 

 and a number taken. Three birds which I have, exceed some measure- 

 ments of stricklandi. 



Loxia leucoptera. A great many small flocks seen and a number of 

 specimens taken. These birds are feeding on the juniper berries. 



Plectrophenax nivalis. A few small flocks of this bird were seen on the 

 Lake shore; the first visit we have had for several years of this bird. 



Coccothraustes vespertinus. A small flock of these birds have been seen 

 at Waukegan by Mr. T. H. Douglass. 



Ampelis garrulus. A small flock seen by Mr. Douglass in his yard. —

Telescope Observations of Migrating Birds. — At Urbana, Illinois, 

 between 9.45 and 10.45 p. m. on the seventh of last October, the writer 

 watched migrating birds through a four-inch telescope directed toward 

 the moon. The diversity in the direction of the flight on this evening 

 seems worthy of record. Out of a total of fifty-four birds, forty-two were 

 flying in a general southerly direction, about one-half of these passing 

 directly southward, while others were headed southwest or southeast. A 

 few passed nearly eastward or westward. The remaining twelve, or 

 nearly one-fourth of the entire number, were flying in a general northerly 

 direction. In determining the direction it was assumed that the flight 

 in all cases was horizontal. Between 9 and 9.20 on the same evening 

 Professor Joel Stebbins, of the department of astronomy, counted thirteen 

 birds flying southward and five flying northward. The wind was from 

 the southeast, and had a velocity of only five miles an hour, as shown 

 l>y an anemometer record. The temperature at 9 p. m. was 52° F.
