.-- Banders look forward to the dy when one of their birds will be recovered or reported at some distant location. This gives meaning and pleasure to the hours spent mist-netting and banding. For me, such a moment occurred in 1972 when one of 167 banded Semipalmated Sandpiper) (Calidris pusillus) was recovered. Band number 800-24307 was placed on this bird at the Cheyenne Bottoms Waterfowl Management Area in central Kansas on 6 May 1972. It was reported at Prudhoe Bay, Alaska on 30 June 1972 where the bird was breeding. The bird was captured by Dr. Wayne C. Hanson during an ecological study of the birds and mammals in the vicinity of the Alaskan Arctic Gas Study Company experi- mental natural gas pipeline test facility six miles south of Prudhoe Bay. The banded Semipalmated Sandpiper arrived at Prudhoe Bay approxi- mately one month after it was banded (2 or 3 June 1972). The banded bird's mate was caught and banded at the nest on 24 June and the earlier banded bird was caught at the nest on 30 June. To facilitate observation the birds were color- marked with red/white celluloid leg rings. Both adults and their chicks were obseed on the 3rd and 5th days after hatching and within 90 to 150 meters of the nest. Semipalmated Sandpiper parents promptly moved their chicks to the vicinity of the larger thaw-ponds in the area to escape human activity and the predation of Arctic Foxes (Alopex lagopus) and Pomafine Jaegers (Stercorarius pomarinus). Care was taken by project personnel not to excite or desperse the birds studied. The observations were terminated when the family groups moved beyond the study area. This recovery is one of nine recoveries of Semipalmated Sandpipers banded at the Cheyenne Bottoms WMA since the beginning of the shorebird banding program in 1967. Four of them were recovered in Guyana, and one each from Brazil, Surinam, Dominican Republic, and New Jersey. Two foreign-banded Semipalmated Sandpipers have been mist-netted during banding operations at the Cheyenne Bottoms; both were banded at Barrow, Alaska. A Semipalmated Sandpiper was retrapped by Dr. Ilanson at Prudhoe Bay, one that had been banded the year before (1971) by a team from the University of Alaska. The bird was caught within 500 meters of its 1971 nesting site. The band carried by this bird was badly corroded, even though it had only been worn for one year. The corroded band was replaced with a new band. The same problem of cor- roded bands has been encountered on shorebirds that returned to the Cheyenne Bottoms banding station. To help alleviate this problem, the shorebirds were banded above the tarsus instead of on the tarsus to reduce contacts with cor- rosive material, such as seawater. Some bands were so unrecognizable that only a mass of oxidized metal remained.
