Woodhouse's Jay is a bird of the foothills, being found 

 in the scrub oak brush along the base of the mountains, and 

 the lower parts of the canons, but not going to any great 

 elevation ; it is also found about Austin's Bluffs. Occasionally 

 in winter it comes into town; from November 20, 1910, to 

 April 16, 1911, at least four were about the north end of 

 Monument Valley Park and vicinity and were frequently seen 

 about houses four or five blocks east of the Park. 



Aiken found two nests May 2, 1872, and his description 

 was the first to be published of the nesting of the species. The 

 nests contained 4 and 5 eggs respectively. His description is 

 as follows: "Nest composed outwardly of dead twigs, then 

 of fine roots, and lined with fine rootlets and horsehair. The 

 eggs, four or five in number, are laid about May 1st. They 

 are of a light bluish-green color, with the reddish-brown specks 

 thickest at the large end." 



When Aiken was at his ranch on Turkey Creek in Oc- 

 tober, 1873, a migratory flight of Woodhouse's Jays was seen. 

 They were not flying high, but making short flights from point 

 to point, always in a southerly direction. It was estimated 

 that there were at least 500 scattered over from 50 to 100 acres 

 of ground, as they kept lighting after their short flights. After 

 this flight had passed the species seemed to be fully as com- 

 mon during the following winter as it had been during the 

 summer. The flight had undoubtedly come from a more north- 

 ern locality. Local birds appear to be non-migratory and are 

 found in the same localities throughout the year.
