Longevity, movements, and site fidelity in Wandering Tattlers Heteroscelus incanus
Bibliographic record
Abstract
and juveniles have been recorded on staging areas in late July (Seward Peninsula and Yukon-Kuskokwim Delta) and early August (NW Alaska) (McCaffery & Gill 2001). The first arrivals of juveniles in New Zealand are typically in the first week of October (PFB, unpubl. data). Depending on where 3E was hatched, it could have fledged any time from mid-July to early August, and been around 8–11 weeks old when caught and banded in Alaska. At its recapture in New Zealand it would have been around 17–20 weeks old. The increase in bill length recorded confirms that godwits migrating south may not have reached adult structural size, though the single recapture cannot tell us whether or not 3E was fully adult in size when it migrated or when recaptured in October. Bar-tailed Godwits are highly variable in size both between and within sexes. Bill lengths in New Zealand range from about 69 to 99 mm in males (mean 83.8, n = 920) and 90 to 129 mm in females (mean 108.9, n = 862); wing lengths range from 210 to 256 mm in males (mean 230.5, n = 472) and 216 to 264 mm in females (mean 243.7, n = 549) (JRC unpubl. data). 3E’s measurements indicate he was a slightly belowaverage sized male when caught in New Zealand. Only 32 juvenile Bar-tailed Godwits have been banded in Alaska recently (2004–2010); of these, just five have definitely been seen on the non-breeding grounds. Opportunities for gaining further information on the duration of growth in godwits will almost certainly remain few and far between. Thanks to Adrian Riegen for leading the cannon-netting in New Zealand, Dan Ruthrauff and Lee Tibbitts for information on the Alaskan godwits, and to Dejan Stojanovic for the use of his photograph. Thanks to Kim Trust of the US Fish and Wildlife Service for funding the avian influenza work at Punaorat Point through which 3E came to be caught. We thank Wlodzimierz Meissner for commenting on a draft of this note.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
