Divja Slovenija: Vodomec, kljub živahnim barvam le redko viden

Spoznajte majhno ptico z dolgim kljunom in spreminjajoče modre barve, ki izkoplje približno meter dolg gnezditveni rov s kamrico. Vodomec je živalska vrsta, ki je predstavljena tudi v dokumentarnem filmu Divja Slovenija, kjer si lahko ogledate pestro favno in floro Slovenije. 

Vodomec (Alcedo atthis) je majhen ptič, za katerega je značilna razmeroma velika glava in približno 4 cm dolg črn kljun. Vrh glave, proga ob kljunu ter krila so zeleno modre barve in posuti s svetlo modrimi pegami. Hrbet in rep pa sta živo modra in se glede na zorni kot opazovanja spreminjata od turkizne do kobaltno modre. Lica in spodnji del telesa so rjasto oranžne barve, grlo in lisa na vratu pa snežno bela, medtem ko so drobne noge odraslih živali svetlo rdeče. Za vodomce velja, da sta oba spola enako obarvana. Samica se loči po rdečini na spodnji strani kljuna, medtem ko je kljun samca povsem črn.

Ogroža ga urejanje rečnih območij in vremenske razmere

Vodomec navadno gnezdi od aprila do junija, v strm, praviloma peščen breg potokov ali rek izkoplje okoli meter dolg rov, ki se konča z gnezdilno kamrico, kjer samica znese šest ali sedem jajc. Starša jajca obdata z izbljuvanimi ribjimi koščicami, nato pa se pri valjenju izmenjujeta. Gnezdišča izginjajo predvsem zaradi utrjevanja rečnih bregov ter uravnavanja rek in potokov. Edino strnjeno gnezditveno območje v Sloveniji je vzdolž reke Drave na Dravskem in Ptujskem polju. Sam gnezditveni uspeh vodomca je odvisen od vremenskih razmer, saj lahko obilno deževje ob nepravem času zalije gnezdo in pomori mladiče. Prav tako daljša obdobja ostrega mraza, ko reke in potoki zamrznejo, terjajo svoj davek med vodomci. V Sloveniji je zato kot močno ogrožena vrsta uvrščen na rdeči seznam.

Plah, a uspešen “ribič”

Vodomca je v naravi težko opaziti, saj se zelo dobro zlije z okolico, tudi ko sedi na veji nad potokom ali reko in opreza za majhnimi ribami in vodnimi žuželkami. Sicer pa velja za precej plahega in previdnega ptiča. Najpogosteje ga lahko opazimo, kako premočrtno leti nizko nad vodno gladino. V dokumentarnem filmu Divja Slovenija je prikazan v obdobju izkopavanja gnezdilnega rova, na enem od redkih območij, kjer v Sloveniji še živi.

Če dokumentarnega filma Divja Slovenija še niste videli ali pa bi ga želeli ponovno pogledati, boste to lahko storili, od 3. februarja 2022, v spletnem kinu Art kino mreže Slovenije, na tem naslovu bo dostopen v slovenski in angleški različici.

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 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 _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.
