In some winters Lawrence's goldfinches tend to move south and 

 eastward through Arizona, New Mexico, and Texas. Winter status 

 of the birds in recent years is indicated by evidence summarized from 

 Audubon Field Notes. Gale Monson (1951a) reported a flight of 

 Lawrence's goldfinches southeastward from their summer range, in 

 the fall of 1950. They were common at Tucson, and the species was 

 present on November 30 at Tumacacori National Alonument, Ariz. 

 The birds were present at El Paso after November 16, including a 

 flock of 42 at Ascarate Lake on December 2. Monson (1951b) says 

 that in late winter this bird is common in lowland areas, including 

 the Rio Grande Valley from Las Cruces, N. Mex., to Fabens, Tex., 

 the last ones being seen at El Paso on March 20. That was the 3rd 

 year in 20 they had visited the Rio Grande. 



In the early winter of 1951 the Lawrence's goldfinches made another 

 eastward flight. About 20 were noted at Tucson on November 4, 

 at Liberty, Ariz., on November 12, and on the Colorado River Indian 

 Reservation on November 9 (Monson, 1952a). In 1953 a flight of 

 this species to central and southern Arizona developed, with records 

 after October 3 at Tucson, Peoria, Wikieup, Hereford, and in Sonora 

 (Monson, 1954a). In 1953-54 more than 50 Lawrence's goldfinches 

 wintered in the El Paso area; nearly 170 were seen at Tucson, 

 January 2, and more than 23 were still present at Tempe by March 17 

 (Monson, 1954b). That spring these birds were widely reported in 

 southern California.
