The six specimens secured come from the following localities: 

 Waverly, May 12 ; Uniontown, May 5 ; Cloverport, May 4 ; and Rocky- 

 branch, June 15. Others were seen at Monticello, June 9; Lynch, 

 June 23 ; and Belfry, July 4.

CYANOCITTA CRISTATA CRISTATA (Linnaeus) : Northern Blue Jay 



With regard to the blue jay the western part of Kentucky represents 

 an area where there is approach to the southern form, most of the 

 few breeding birds seen having the brighter blue color and more ex- 

 tended white on wing and tail of the northern form but ranging some- 

 what small for the average of that bird. Two males from near the 

 northern arm of Reelfoot Lake measure 123.8 and 127.8 mm. in length 

 of wing but are definitely bright blue above. This is of particular 

 interest when it is remembered that birds from only slightly farther 

 south in Obion County, Tenn., are nearer the southern form. A male 

 from Waverly shot on May 11 is even deeper blue, though it measures 

 only 122.5 mm., while another from Morganfield nearby, with the wing 

 132.9 mm., meets the full requirements of cristata in color, markings, 

 and size. Two males from Brandenburg, measuring 127.2 and 129 

 mm., are a little small but otherwise typical of cristata. A male from 

 4,100 feet elevation on Black Mountain near Lynch, with the wing tip 

 rather worn still measures 130 mm. Other breeding birds that agree 

 with the northern type in color come from Quincy, July 11 and 13, 

 though in these the ends of the primaries are much frayed from wear 

 so that their actual measurements (119.6 and 128.7 mm.) are 5 to 10 

 mm. or so below what they would have been when the birds were in 

 proper feather. An immature bird just from the nest was secured here. 



Birds were taken in fall as follows: Madisonville, October 24 

 (male, wing 128 mm.) ; Sacramento, October 17 (males 127.4, 136,1, 

 female 127.2) ; English, Carroll County, October 12 (127) ; Browns- 

 ville, November 10 (130.6); and Morehead, October 8 (125). On 

 the basis of size part of these are intermediate, but in color and in 

 amount of white they belong with cristata. 



The intermediate character of the blue- jay population of the State 

 is easily evident from this brief account. The interpretation pre- 

 sented may be subject to some modification with more material but 

 is the best that can be given at present.
