L’orca Wikie ha imparato a “parlare” come un essere umano: l’audio

in foto: L’orca Wikie con sua figlia

Per la prima volta un'orca (Orcinus orca) ha imparato a imitare suoni non legati al linguaggio dei cetacei, tra i quali diverse parole umane come “bye bye”, “hello” e altri termini semplici. Naturalmente non significa che questi magnifici mammiferi marini hanno imparato a parlare la nostra lingua, ma si tratta dell'ennesima dimostrazione della loro straordinaria intelligenza, che mette in luce una spiccata capacità nell'apprendimento vocale. Nel 2014 alcuni esemplari di orca avevano già dimostrato di aver imparato a replicare il “delfinese”, nello specifico i click e i suoni emessi dal alcuni tursiopi – le orche del resto non sono altro che grossi delfini -, ma oggi sappiamo che possono andare oltre i versi dei cetacei.

Protagonista della vicenda un'orca femmina di 17 anni chiamata Wikie, che purtroppo non è libera in natura ma vive in cattività è una delle controverse “attrazioni” al Marineland Aquarium di Antibes, in Francia. Il cetaceo in passato aveva già ricevuto una sorta di corso introduttivo all'imitazione, e anche grazie ad esso un team internazionale di ricerca è riuscito a fargli imparare suoni – come una porta che cigola – e soprattutto parole umane. Wikie è così abile che può imparare nuovi termini entro una decina di tentativi. Per tre di essi vi è riuscita persino al primo. Potete ascoltare la sua "voce" qui di seguito.

L'imitazione delle parole non è sempre precisa, ma è evidente l'intento dell'animale di calibrare i suoni per adattarli a quelli dell'istruttrice. Ad oggi sono noti soltanto i casi di altri tre mammiferi in grado di replicare distintamente parole umane: un beluga (Delphinapterus leucas) nel 2012 una foca comune (Phoca vitulina) nel 1985 e un elefante asiatico (Elephas maximus) nel 2012. Le performance imitative di uccelli come pappagalli, merli e altre specie sono invece piuttosto note. Straordinaria la capacità di un uccello lira nell'imitare i suoni di strumenti e giocattoli “ascoltati” all'Healesville Sanctuary, un parco naturale in Australia.

Tornando all'orca Wikie, per quanto sia affascinante sapere che questi cetacei possono persino imitare la nostra voce, deve comunque far riflettere che si tratta di un animale privato della sua dignità e della libertà. Le orche sono creature oceaniche che vivono in pod – gruppi famigliari – dove si “parlano” addirittura dialetti specifici, uno diverso dall'altro. Wikie non ha potuto imparare il proprio per colpa dell'avidità dell'uomo. Non è un caso che i risultati di questa ricerca, pubblicati sulla rivista scientifica Proceedings of the Royal Society B., siano stati tacciati di non avere alcun valore scientifico. Non si può inoltre escludere che le imitazioni di Wikie verranno sfruttate anche per far "divertire" il pubblico pagante, alimentando l'ingiusto mercato dei cetacei in cattività.


Progetto Whalesafe: in funzione sistema che rileva suoni emessi da capodogli

Il progetto Whalesafe per la conservazione dei capodogli (Physeter macrocephalus) è entrato nella sua fase più importante

Il progetto Whalesafe per la conservazione dei capodogli (Physeter macrocephalus) è entrato nella sua fase più importante: la rilevazione dei suoni emessi dai capodogli, che ne rivelano la presenza e la posizione, e l’analisi dei dati raccolti che consentirà di attivare il sistema di alert alle navi in entrata e in uscita dal porto di Vado Ligure per evitare possibili collisioni con i cetacei. Lo annuncia Costa Edutainment. Il progetto Whalesafe, cofinanziato dall’Unione Europea attraverso il programma Life+, è coordinato dall’ Università di Genova (Dipartimento di Fisica e Dipartimento di Scienze della Terra, dell’Ambiente e della Vita) insieme ai seguenti partner: Costa Edutainment, Direzione Marittima di Genova Capitaneria di Porto di Savona e Softeco Sismat.

È in funzione un sistema che determina la presenza dei capodogli tramite l’ascolto dei segnali sonori emessi da questi grandi mammiferi marini. L’unità di ascolto è costituita da una boa, denominata Adelina, ancorata su un fondale scosceso a una profondità di 400 metri davanti al porto di Vado.

La boa è corredata di pannelli fotovoltaici, di un sistema di rilevazione acustica, costituito da quattro idrofoni, e di un sistema di trasmissione dati a terra.

L’unità di ascolto riceve due segnali provenienti dal capodoglio: il primo è il suono diretto e il secondo quello riflesso dalla superficie del mare. Un computer posto sulla boa elabora i segnali e determina la direzione di arrivo del raggio sonoro e quindi la posizione del capodoglio e la sua rotta di spostamento.

Nel Comune di Bergeggi è posto il computer principale, che riceve i dati dalla boa mediante wi-fi grazie a un’antenna parabolica ospitata. Il computer e il sistema di immagazzinamento sono in rete con il Dipartimento di Fisica dell’Università di Genova consentendo ai ricercatori di avere accesso ai dati in tempo reale.

In sei settimane di funzionamento il sistema ha registrato i suoni di diversi cetacei, in particolare nei primi giorni di luglio ha identificato la presenza di capodogli in transito nell’area di mare davanti al porto di Vado e grazie alle informazioni acquisite ha permesso il 13 di luglio l’avvistamento di due individui. Sul sito del progetto sarà presto inserita una cartina che consentirà di vedere il numero degli individui rilevati, il luogo in cui stavano transitando e il giorno.

Oltre al sistema di monitoraggio, è stato sviluppato un protocollo di condotta per ridurre i rischi di disturbo e di collisione che ad oggi è già stato firmato da Costa Crociere e da altri enti e organizzazioni che operano nell’area interessata. La fase successiva del progetto prevede l’attivazione del sistema di segnalazione della presenza dei capodogli alle navi in ingresso e in uscita dal Porto di Vado. Al momento del ricevimento dei messaggi di avviso, le navi presenti nell’area saranno invitate a seguire il protocollo e la Capitaneria di Porto di Savona supervisionerà la sua applicazione.

Grazie al coinvolgimento di tutte le parti interessate dal traffico marittimo nell’area, il progetto intende perseguire concretamente il miglioramento della protezione dei capodogli, favorendo la coesistenza sostenibile di questa specie di cetaceo con le attività antropiche e promuovendo azioni per l’utilizzo responsabile del mare. Il traffico marittimo può causare seri problemi ai capodogli, sia per le possibili collisioni, sia per l’inquinamento acustico.


Il verso del coccodrillo: il trimbulare

Una famosa canzone del 1993 diceva: "Il coccodrillo come fa? Non c'è nessuno che lo sa". In verità, questa è una bugia. Questo rettile anfibio, che come gli alligatori fa parte dell'ordine dei Crocodylia ma differisce da questi ultimi per caratteristiche fisiche, è infatti un animale molto rumoroso che comunica con i versi sin da quando è ancora nell'uovo, da dove richiama l'attenzione della mamma. Il suo trimbulare è caratterizzato da un insieme di suoni gravi, tremuli e acuti.
