Alti tassi di deformità gravi nelle popolazioni di fauna selvatica spesso fungono da indicatori di problemi di salute ambientale sottostanti. Questo studio rappresenta il primo e più completo tentativo possibile di documentare le deformità negli uccelli in Algeria, includendo anomalie del becco e del piumaggio, leucismo, albinismo e melanismo.
Nel corso di dieci anni, sono stati documentati 50 casi di deformità in 20 province, appartenenti a trenta specie, diciotto famiglie e dieci ordini. In 13 casi sono stati osservati becchi anomali, comprese condizioni come mandibole incrociate, mandibole allungate e becchi disallineati, che potrebbero influire significativamente sulla capacità degli uccelli di alimentarsi e pulirsi efficacemente.
Il leucismo, sia parziale che completo, è stato l'anomalia più comune, rilevata in 35 casi, con il leucismo parziale come forma più frequente (n=23). Albinismo e melanismo sono risultati rari, osservati ciascuno in un solo caso. I Passeriformi hanno mostrato il maggior numero di deformità, in particolare il Passero domestico (Passer domesticus, n=5) e il Merlo comune (Turdus merula, n=3). Inoltre, sono stati osservati più casi di leucismo nella Tortora dal collare orientale (Streptopelia decaocto, n=6).
È importante sottolineare che le deformità sono state registrate sia in specie residenti (23 specie) che migratrici (7 specie), con un numero significativamente maggiore di casi osservati nelle specie residenti. Questo studio evidenzia l'importanza di un monitoraggio continuo e di ulteriori ricerche per comprendere le cause alla base di queste deformità e le loro implicazioni per la conservazione degli uccelli in Algeria.
