cranes wintering near the Ignited States-Mexico 

 border near Coliiinbus, N. Mex., consists of a 

 mixed group of the greater and lesser forms. 



Experiments concerned with the development 

 of techniques for capturing and color-marking 

 sandhill cranes were carried out on the Muleshoe 

 and Bitter Lake National Wildlife Refuges by 

 refuge staff members and New Mexico Game and 

 Fish Department pei-sonnel. 



Methods of trapping included the cannon net, 

 foot snares, modified steel traps, pen-type "walk 

 in" bait traps, "jacklighting," and electrical stun- 

 ning. Aerial spraying, hand marking, and smear 

 lines were employed in color-marking experiments. 



A sandhill crane rearing study was initiated in 

 early April 1962. On May 10, 29 eggs were col- 



lected from 15 greater sandhill crane nests on the 

 Malheur National Wildlife Refuge in southeastern 

 Oregon and transferred to Santa Fe, N. Mex., 

 \\ liere hatching and rearing facilities were avail- 

 able through the cooperation of William S. Huey, 

 Biologist, New Mexico Department of Game and 

 Fish. Bantam hens and an electric incubator were 

 used for the completion of incubation. Both 

 methods proved to be highly successful as only 2 of 

 the 29 eggs failed to hatch. During the rearing 

 period, 7 young cranes were lost owing to various 

 causes, but 20 were successfully reared to adult size. 

 In early August, 14 of the hand-reared young were 

 transferred to the Monte Vista Wildlife Refuge 

 where they are being held in captivity for propaga- 

 tion purposes. The remaining six are being re- 

 tained at Santa Fe for detailed behavior studies.
