Anuario ornitológico de La Rioja 2013-2015
Bibliographic record
Abstract
The present article aims to show the most interesting ornithological observations carried out between the years 2013 and 2015 in La Rioja, and is an update of the existing information so far. Furthermore, this article contains a brief description of the status, abundance, distribution, migrating habits and phenology of all the species of birds observed in La Rioja. Out of the 302 wild birds registered in La Rioja, this report provides a total of 301 records for 121 of them. Here are the first records of Canada goose (Branta canadensis), Longlegged buzzard (Buteo rufinus) in La Rioja as well as Purple swamphen (Porphyrio porphyrio), Marsh sandpiper (Tringa stagnatilis) and Great skua (Stercorarius skua). We also show the second records of Western reef heron (Egretta gularis), Glossy ibis (Plegadis falcinelus), Pallid harrier (Circus macrourus), Greater spotted aegle (Aquila clanga) and Bar-tailed godwit (Limosa lapponica). And the third of Ring-necked duck (Aythya collaris). Four new species are added to the list of exotic species escaped from captivity: American wood duck (Aix sponsa), Spot-billed duck (Anas poecilorhyncha), Chilean flamingo (Phoenicopterus chilensis) and Java sparrow (Padda oryzivora). The article includes 17 records of 12 of the 32 species that make up the list. For the first time, we get data about actual reproduction of the Canada goose (Branta canadensis) in the river Ebro in Alfaro, the Common shelduck (Tadorna tadorna) and the Black-headed gull (Chroicocephalus ridibundus) in the Lake of Herramélluri, and the Purple swamphen (Porphyrio porphyrio) in El Recuenco, Calahorra. Being sporadic, it is interesting to note the reproduction of the Gadwall (Anas strepera) in Murillo de Río Leza, the Northen shoveler (Anas clypeata) in the Lake of Herramélluri, the Back-necked grebe (Podiceps nigricollis) in the lagoon of Hervías, the Great cormorant (Phalacrocorax carbo) in the river Ebro in Gimileo, and the Little bittern (Ixobrychus minutus) in El Recuenco, Calahorra. For the first time, we get data of the regular wintering of the Black-crowned night heron (Nycticorax nycticorax) in La Rioja. Every winter, at least since 2012-13, a small population stays by the river Ebro where it crosses Logroño. In 2013 and 2014, we get many records of the Bar-tailed godwit (Limosa lapponica) during their prebreeding migration in different wetlands in La Rioja; and also one record during postbreeding migration. So far we only had one record of this species. The Bearded reedling (Panurus biarmicus) keeps spreading in La Rioja. This species is already reproducing in El Salobral of Pradejón and El Recuenco of Calahorra.

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.
