Bibliographic record
Abstract
Effective management of the midcontinent sandhill crane (Grus canadensis) population requires having detailed information available on the distribution of subspecies and subpopulations throughout the annual cycle. The current study is being undertaken in partnership with several federal and state agencies and private organizations to obtain key information not currently available. We are monitoring crane movements throughout the year by attaching Platform Transmitting Terminals (PTTs) to plastic leg bands and with the aid of equipment on board orbiting NOAA weather satellites relocating the radiomarked individuals at 4-10 day intervals throughout the year. Twenty-one cranes were captured and radio-marked in the Central Platte River Valley in early spring 1998 and 1999. Results to date indicate the technique is well suited for obtaining the types of information being sought. Most of the radio-marked cranes after departing from the Platte River in spring staged again at sites in southern Saskatchewan but those of the Canadian subspecies (G. c. rowan i) breeding in Manitoba and Ontario staged in northwestern Minnesota. Distnbution of radio-marked individuals on the breeding grounds suggests that northeastern Russia may be a more important breeding area for lesser sandhill cranes (G. c. canadensis) than previously thought; 50% of lesser sandhill cranes tagged to date (6 of 12) migrated to locations in northeastern Siberia. Onset offall migration occurred from mid-August to mid-September depending on latitude; fall staging was centered primarily in 3 areas of southern Saskatchewan with fewer radio-marked cranes staging in southwestern Manitoba and central North Dakota. Most radio-marked cranes have spent winter in west Texas, 2 (both G. c. rowani) have occupied sites near the Texas Gulf Coast, and 1 each spent winter at sites in Arizona and New Mexico (both G. c. canadensis breeding in northeastern Siberia). Habitats occupied by cranes are being identified throughout the annual cycle with the aid of GIS methodology as are temporal and spatial patterns of use of the Central Platte River Valley. Information obtained from the study will be used to delineate breeding ranges, migration corridors, staging areas, and wintering grounds of subspecies and subpopulations to allow crane managers to better meet the needs of the midcontinent population. Current plans are to gather information on a total of 200 sandhill cranes over the study period with 42 cranes to be radio marked in 2000. Those interested in following the radio-marked cranes during their annual cycle or learning more about the crane study can do so by logging on our web site at www.npwrc.usgs.gov/perm/cranemov/cranmov.htm.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
