Maurice Broun (1935) says of the fall migration at Kittatinny 

 Ridge, Pa., in 1934: 



It may come as something of a surprise to learn that these splendid birds 

 made up fully 50% of the entire Hawk migration. The first Red-tails recorded 

 were two on September 30. No conspicuous movement toolc place until October 

 12, when 205 birds were counted. Thereafter during the monlh there were nine 

 days of relatively heavy flights, the greatest number of 427 birds occurring on 

 October 23. The first part of November, however, brought the major flights, 

 with an average of 244.5 birds per day for 12 days. On November 1, I recorded 

 592 Red-tails — as many as 213 in a single hour ; on November 2, 853 Red-tails. 

 Kramer reported diminishing numbers of Red-tails during the latter part of 

 November, except for 67 on the 24th. He saw 9 on December 2, and 4 on the 

 next day.
