Urban gulls of the Pacific coast of North America: Balancing wildlife conflict concerns with the protection of urban breeding sites
Bibliographic record
Abstract
Abstract: Gulls are one of the very few avian taxa to occur on all continents, and many species have adapted remarkably well to living alongside humans in urban environments. Paradoxically, many of these species continue to experience overall population declines, even as urban-nesting populations grow. In this talk, we will present details about several gull species that occupy the Pacific coast of North America: Glaucous-winged (Larus glaucescens), Western (L. occidentalis), Herring (L. argentatus), Mew (L. canus), and Heermann's (L. heermanni). Drawing on six years of field work across Canada and the US, we will compare and contrast the urban ecologies of these species with those of their declining, non-urban conspecifics. Nest site demographics, as well as colony density, nest fidelity, and reproductive success figures will be presented. We will also discuss several spatial models that we have developed to predict urban-nesting behaviour in these species. As urban-nesting becomes more commonplace, a host of new human-wildlife conflicts can arise, as well as many exciting conservation opportunities. These issues and ideas demand a deeper knowledge of the breeding ecology of urban gulls, and our work represents another step toward this.

How this classification was reachedexpand
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.
