Severno Italijo je zavzela invazivna tujerodna vrsta ptic

Sveti ibis se je iz svoje rodne Afrike razširil v nove evropske habitate, zlasti v dele severne Italije, kjer ogroža lokalne divje živali.

Afriški sveti ibis je invazivna vrsta, za katero se domneva, da je pobegnila ali je bila izpuščena iz ujetništva in je priletela v Italijo.

Vrsta je sicer doma v Afriki in Iraku, zdaj pa se zelo hitro širi po severni Italiji. »Sveti ibis je začel množično gnezditi v Bologni, Modeni in zlasti v Ferrari,« je povedal Andrea Ravagnani iz združenja ornitologov AsOER Emilije-Romanje, ki verjame, da bi lahko bilo v severnoitalijanski regiji že na desettisoče ptic.

Kako prepoznati ptico sveti ibis?

Sveti ibis (Threskiornis aethiopicus) je močvirska ptica, za katero so značilne dolge črne noge in vrat, prav tako črn kljun pa je dolg in ukrivljen navzdol. Njena peresa so pretežno bela, le letalna peresa imajo črne konice, ki so dobro vidna v letu iz zgornje in spodnje strani. Sicer pa je sveti ibisi družabna ptica, ki se pogosto druži z drugimi močvirskimi pticami, predvsem z

žličarkami ter belimi čapljami. V zadnjem desetletju je bil večkrat opažen tudi v Sloveniji.

Zakaj predstavlja problem?

V Evropi je afriški sveti ibis že skoraj desetletje na seznamu invazivnih tujerodnih vrst, saj pleni dvoživke ter jajca in mladiče drugih vrst, zlasti čigre in čaplje, s čimer povzroča škodo lokalni biotski raznovrstnosti in ogroža preživetje mladičev domorodnih vrst.

Poleg tega se hrani z ličinkami žuželk na odlagališčih odpadkov, s čimer širi bolezni, ki se prenesejo na pašnike in perutninske farme.

_hjClosedSurveyInvites Hotjar cookie. This cookie is set once a visitor interacts with a Survey invitation modal popup. It is used to ensure that the same invite does not re-appear if it has already been shown. 365 days _hjDonePolls Hotjar cookie. This cookie is set once a visitor completes a poll using the Feedback Poll widget. It is used to ensure that the same poll does not re-appear if it has already been filled in. 365 days _hjMinimizedPolls Hotjar cookie. This cookie is set once a visitor minimizes a Feedback Poll widget. It is used to ensure that the widget stays minimizes when the visitor navigates through your site. 365 days _hjDoneTestersWidgets Hotjar cookie. This cookie is set once a visitor submits their information in the Recruit User Testers widget. It is used to ensure that the same form does not re-appear if it has already been filled in. 365 days _hjIncludedInSample Hotjar cookie. This session cookie is set to let Hotjar know whether that visitor is included in the sample which is used to generate funnels. 365 days _hjShownFeedbackMessage This cookie is set when a visitor minimizes or completes Incoming Feedback. This is done so that the Incoming Feedback will load as minimized immediately if they navigate to another page where it is set to show. 365 days _hjid Hotjar cookie. This cookie is set when the customer first lands on a page with the Hotjar script. It is used to persist the Hotjar User ID, unique to that site on the browser. This ensures that behavior in subsequent visits to the same site will be attributed to the same user ID. 365 days _hjRecordingLastActivity This should be found in sessionStorage (as opposed to cookies). This gets updated when a visitor recording starts and when data is sent through the WebSocket (the visitor performs an action that Hotjar records). Session hjTLDTest When the Hotjar script executes we try to determine the most generic cookie path we should use, instead of the page hostname. This is done so that cookies can be shared across subdomains (where applicable). To determine this, we try to store the _hjTLDTest cookie for different URL substring alternatives until it fails. After this check, the cookie is removed. Session _hjUserAttributesHash User Attributes sent through the Hotjar Identify API are cached for the duration of the session in order to know when an attribute has changed and needs to be updated. Session _hjCachedUserAttributes This cookie stores User Attributes which are sent through the Hotjar Identify API, whenever the user is not in the sample. These attributes will only be saved if the user interacts with a Hotjar Feedback tool. Session _hjLocalStorageTest This cookie is used to check if the Hotjar Tracking Script can use local storage. If it can, a value of 1 is set in this cookie. The data stored in_hjLocalStorageTest has no expiration time, but it is deleted immediately after creating it so the expected storage time is under 100ms. N/A _hjptid This cookie is set for logged in users of Hotjar, who have Admin Team Member permissions. It is used during pricing experiments to show the Admin consistent pricing across the site. Session _hjAbsoluteSessionInProgress The cookie is set so Hotjar can track the beginning of the user's journey for a total session count. It does not contain any identifiable information. 30 minutes
