 spotted and barred at tip with light grayish and dull whitish. (Middle 

 pair of tail-feathers grayish brown or brownish gray, barred or trans-

c 2 . Tail equal to or longer than wing. (Nest usually about buildings, 



except in unsettled districts. Eggs 5-7 — rarely 9 — pure white or 



pinkish white, finely, often very minutely, speckled or sprinkled 



on or round larger end with reddish brown and lilac-gray.)

2.05-2.25 (2.14), tail 2.10-2.40 (2.21), exposed culmen .50-.55 



1 Specimens from northeastern Mexico constitute the T. berlandieri JJaird, which will probably prove ten- 

 able as a race, the three specimens upon which the species was based, although in worn breeding plumage, beiDg 

 much deeper rusty ochraceons beneath even than in winter specimens of T. ludovicianus, and also different in 

 some other characters. All Texan specimens, however, that I have seen, including several from the lower Rio 

 Grande (Senhktt), are so like the ordinary northern birds that I am unable to appreciate any difference.
