A Field Guide to the Birds of Gambia and Senegal, by Clive Barlow and Tim Wacher [Review]
Bibliographic record
Abstract
This is a no-nonsense bird book.With little preamble, it concentrates on depicting and describing the birds of Madagascar.Indeed, virtually all the book is devoted to the main topic.There is an introduction to habitat types and the distribution and conservation of birds and bird watching sites.While brief, these sections do impart the critical information needed.I was mildly surprised when the authors used almost three pages on the widely-available depictions of bird topography!The remainder of the book is in standard field guide style.There is a description of two species on the left page and illustrations on the right.This is almost exclusively a photographic guide.The authors write that they chose photographs that portray the key features needed for field recognition.While this is generally true, there are some exceptions.There are nine additional, appealing paintings by Mark Andrews.For seven species, mostly rare endemics, this is the sole portrayal of the birds.For several other species (notably Rand's Warbler, Grey Emutail, Brownthroated Sand Martin, African Black Swift, Madagascar Spinetail, Madagascar Snipe, and Bat Hawk) the photographs are really too poor to be of use in identification.In other cases, while the photograph is good, a key component is obscure.For example, the crest on the Madagascar Cuckoo Hawk is not visible.In these cases there are no fill-in illustrations by an artist and this is unfortunate.Of the seven species quoted above, four are endemic.The three species to be found in nearby Africa are represented in some of the African texts.

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.
