Gray Wolf Recovery
Weekly Progress Report
Week of Feb 18 - Feb 24, 1997
Yellowstone conducted telemetry flights on the 17th and 18th: all wolves were located, except #39, in
expected areas. On the 19th, #39 (female that had been in the Crazy Mountains north of the Park) was back
in the Lamar Valley. She was alone. To their knowledge this is the first time she has been inside the Park
during the past few months.
The 13 wolves that were recently transferred to the Nez Perce pen are doing well.
No new information for Idaho. This is the peak of wolf breeding season and there are about 10 potential
breeding pairs in Idaho this winter.
The Service plans to hire 4 seasonal field biologists this summer for 6 months beginning in April. Interested
persons should send their name and address to USFWS, 100 N. Park, Suite 320, Helena, MT or FAX (406)449-5339.
Once the jobs are advertised everyone will be notified and SF-171's will be solicited.
Livestock Depredations & Management (control)
A wolf-like canid apparently killed 5-8 sheep near Big Timber, Wyoming (SW of Lander, WY) last week. On
Friday the rancher roped (yes- roped!) it from a snowmachine and put it in his horse trailer. The Service
picked it up, had a veterinarian treat its cuts, and held it over the weekend. It is a young 75 lb. female
in estrus, looks like a wolf, and is in good health. It is apparently unmarked and there a several possible
sources for this animal. It could be a released captive wolf, a long-range disperser from NW Montana, or
undocumented offspring of the Yellowstone or Idaho reintroduced wolves. This animal has also stimulated
renewed speculation about the "native Wyoming wolf" (a theory that wolves never were exterminated from
Wyoming). On the 24th, it was transferred to Yellowstone National Park and will be placed in the Rose Creek
pen for observation. Blood samples were taken and analysis will be done from a DNA standpoint but it is
quite possible that its origin may never be known. If it appears to be a wild wolf it will be radio-collared,
released, and monitored. The only sure fire test may be to monitor its behavior in the wild. Wild wolves
usually make it, release captive wolves don't.
Nothing new to report.
