Hybridization from Possible Sexual Mis-imprinting: Molecular Characterization of Hybridization Between Brown Sula Leucogaster and Blue-footed Boobies S Nebouxii
Bibliographic record
Abstract
Hybridization occurs commonly between avian taxa but apparently less frequently between seabird species.The causes and consequences of hybridization between seabirds have been explored in a number of recent papers, highlighting that hybridization may be an important aspect of seabird evolution in some groups.Hybridization has been reported between three pairs of booby species; however, only one of these has been investigated in any depth.We report the first molecular investigation of hybridization between Blue-footed Sula nebouxii and Brown S. leucogaster boobies.We used a fragment of the mitochondrial control region and a panel of microsatellites and introns to robustly classify two aberrant individuals collected in the Gulf of California as F1 hybrids.Hybridization between these species may be restricted to colonies where both species breed in close proximity and could be the result of sexual imprinting on the wrong parental species.

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.
