Abstract

V letih 2016 in 2017 smo na območju reke Drave med Mariborom in Središčem ob Dravi opravili raziskavo, s katero smo ugotovili selitvene vzorce malega deževnika (Charadrius dubius). V letu 2016 smo na območju raziskave s pastjo na gnezdu ulovili in z geolokatorji opremili 17 malih deževnikov. V letu 2017 smo ponovno ulovili 8 osebkov in dobili popolne podatke za 7 naprav (ena naprava je prenehala delovati že nekaj dni po namestitvi). Pridobljene podatke o moči ambientalne svetlobe smo obdelali s programskim paketom BASTRACK in tako dobili dve lokaciji za vsak dan. Iz zbranih podatkov smo določili postajališča in prezimovališča ptic in opisali njihov selitveni vzorec. Mali deževniki z reke Drave so gnezdišča v povprečju zapustili 30. junija. Pomembna postajališča zanje so sredozemska obalna mokrišča ter celinska mokrišča Balkanskega polotoka, Turčije in severne Afrike. En osebek je prezimoval v Tuniziji, eden v Egiptu, pet osebkov pa na relativno majhnem območju Podsaharske Afrike, zahodno od Čadskega jezera. V povprečju so na prezimovališčih preživeli 173,6 dni. Selitvena strategija malih deževnikov je serija hitrih premikov med številnimi selitvenimi postojankami, spomladanska selitev pa se predvsem zaradi veliko krajših postankov (postanki povprečno 11,8 dni), odvije precej hitreje kot jesenska (postanki povprečno 72,9 dni). Na gnezdišča so se ptice v povprečju vrnile 27. marca, povprečna dolžina celotne selitvene poti pa je znašala 7285,3 kilometra.

Secondary title: migration patterns of Little Ringed Plover (Charadrius dubius) from Slovenia using geolocator tagging
Secondary abstract: Between 2016 and 2017, migration patterns of Little Ringed Plover (Charadrius dubius) were studied on river Drava between city of Maribor and village Središče ob Dravi. 17 birds were traped using walk-in traps placed on nest and equipped with geolocators in 2016. Using the same method we recaptured 8 birds in 2017 and recovered 7 sets of complete data (one set was lost because of device failure few days after deployment in 2016). Ambient light data was analysed using BASTRACK softwere which yielded two locations per day. Using determinated stop-overs and winternig sites we described migration patterns of Little Ringed Plover. Little Ringer Plovers breeding on river Drava left breeding ground on average on June 30th. Important stopovers were Mediteranean coastal wetlands, but also continental wetland of the Balkan peninsula, Turkey and North Africa. One individual wintered in Tunisia, one in Egypt and five in a rather small area west of Lake Chad. Wintering period lasted on average 173,6 days. Migration strategy of Little Ringed Plover is a hop strategy and spring migration is much faster then fall migration, due to shorter stopovers (on average 11,8 and 72,9 days respectively). On average birds returned to the breeding grounds on March 27th. Entire lenght of the migration track was on average 7285,3 kilometers.
