Svet ptic: Siva gos – redka gnezdilka v Sloveniji

V Sloveniji je zelo redka gnezdilka, a jo lahko opazujemo vse leto – tudi na preletu in na prezimovanju.

Sivo gos (Anser anser) spoznamo po dolgem in krepkem vratu ter veliki svetli glavi. Močan kljun je bledo oranžne barve.

Vrat in telo sta svetlo siva ter ozko temno progasta. Hrbet in krila so nekoliko temnejši, spodnji del telesa za zamolklo rožnatimi nogami pa je bele barve.

Siva gos je rastlinojeda ptica, ki se prehranjuje predvsem v jutranjem in večernem mraku. Najraje si privošči travne bilke in rastlinske brsti, liste, poganjke, plodove ter semena močvirskega in vodnega rastlinja.

Seli se glede na vremenske razmere

Za gnezdenje ji najbolj ustrezajo plitva jezera z obsežnimi in dovolj gostimi trstišči ter otočki na velikih jezerih ali ob obali. Plitvo gnezdo zgradi z rastlinskega materiala in ga skrije na tleh. V manjših skupinah gnezdi od aprila do maja, potem pa se začnejo zbirati tudi v par desettisočglave jate.

Seli se glede na vremenske razmere, nekatere populacije se pred ostrim mrazom redno selijo na jug, druge vse leto ostanejo na istem območju. V Sloveniji je zelo redka gnezdilka, a jo lahko opazujemo vse leto – tudi na preletu in na prezimovanju.

Sivo gos ogroža izguba življenjskega prostora

Sivo gos najbolj ogroža izginjanje njenega življenjskega prostora zaradi izsuševanja in spreminjanja v kmetijske površine ter izkopavanja šote. Na območjih gnezdenja pa zlasti požiganje in prekomerna košnja trsta. Ogrožata jo tudi lov in zastrupitve s svinčenimi šibrami, ki jih poje skupaj s hrano.

To function properly, Hotjar stores first-party cookies on your visitor's browser. Cookies are either set by the Hotjar script, or by visiting Hotjar's website. Displaying the correct content to your visitors without personally identifying anyone relies on Hotjar's cookies.

_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
