Nest-dwelling Mites of Selected Common Bird Species in Sri Lanka
Bibliographic record
Abstract
Bird nests primarily function to protect and incubate eggs and nestlings. However, nests are also host to a broad diversity and abundance of arthropod associates, primarily mites (Acari). Our knowledge of nest dwelling mites of common bird species in Sri Lanka is quite limited and necessitates further study. Five different types of nests of selected common bird species (18) in Sri Lanka in urban, suburban, wild, and captive populations were sampled opportunistically using a portable mini vacuum trap. ANOVA: single factor test was used to evaluate statistical significance at p<0.05. A total of 1493 mites were collected from 180 nests. The mites belonging to order Mesostigmata had the highest relative abundance (58.6%) and prevalence (74.4%) of all mite orders collected, followed by the Sarcoptiformes (41.1%, 72.8%), and Trombidiformes (0.3%, 2.2%). Mite diversity of host bird species was measured using the Shannon-Weiner diversity index (H’). Pycnonotus cafer nests had the highest diversity of mites. Cup-shaped nests were host to the highest average abundance value (13.4) of mites, while cavity nests had the lowest value (5.7). Nests from captive populations had the highest average abundance (24.6) of mites and the nests of suburban populations had the lowest value (7.2). These findings can be used as a baseline data set for further detailed research studies on nest-dwelling mites of birds, focusing on avifaunal conservation and the impact on human health by nest-dwelling ectoparasites, built-in human habitations in Sri Lanka.

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.
