Abstract

fetched live from OpenAlex

We surveyed Yellow Rails (Coturnicops noveboracensis) in three marshes located in southeastern James Bay, Canada, in order to document the status and distribution of this species at risk. Night-surveys of calling males were made along 75 km of line transect on 21-25 July 2002, and 186 individual Yellow Rails were recorded: 80 in Cabbage Willows Bay, 77 in Boatswain Bay, and 29 in Hall Cove. Daytime surveys yielded 19 additional calling males, giving a total of 205 male rails. Transects were distributed in plant communities dominated by Slimstem Reedgrass (Calamagrostis stricta), Chaffy Sedge (Carex paleacea), Buckbean (Menyanthes trifoliata), or by Red Fescue (Festuca rubra). There was an overall density of 0.05 calling rails per ha with maximum densities in Boatswain Bay (0.08 male/ha) and Hall Cove (0.06 males/ha). Densities calculated for specific plant communities permitted an estimate of 397 male Yellow Rail inhabiting the marshes: 216 in Boatswain Bay, 132 in Cabbage Willows Bay, and 49 in Hall Cove. The highest densities were in Chaffy Sedge stands, Slimstem Reedgrass stands, and fens dominated by Buckbean. This study indicates that the Yellow Rail is a common bird in coastal high-marshes of the southeastern James Bay, and revealed the highest densities ever reported for the species. The extensive estuarine tidal marshes found in southern James Bay may be home of a thousand or more adult male Yellow Rails and thus represents a key area for this species.

Teacher imitation

Not 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.
