Denac, Damijan (author), Vrezec, Al (author)

On 28 Apr 2005, a dead young (2Y) male Tengmalms Owl Aegolius funereus was found on the island of Pag (N Dalmatia, Croatia) in bare karst area of the rocky Ravna plateau (app. 200 m a.s.l.) of Mt. Dolac. So far, only four published data of Tengmalms Owl occurrence in the coastal part of Croatia exist, and all of them are older than 70 years. The bird most probably migrated to the island from its nearest breeding area-Mt. Velebit. According to the literature, part of the population, especially young birds and females,are nomadic during the non-breeding period. But the question on the habitat used on the island of Pag remains open. It is known that during the non-breeding period. But the question on the habitat used on the island of Pagremains open. It is known that during the non-breeding period, Tengmalms Owls usually move within their potential breeding range and habitat, which is probably not the case as far as this find is concerned. The carcass was found under the turbine of the wind farm, and collision with the turbine was clearlythe cause of the birds death. To our knowledge, no monitoring to evaluate the impact of the discussed wind farm on bird mortality exists, but should certainly be started in view of the references and data presented herewith.

• Title: Koconogi čuk Argolius funereus najden v goli kraški krajini otoka Pag (S Dalmacija, Hrvaška)

Abstract

Dne 28.4.2005 je bil na Pagu na goli kraški planoti "Ravna" (cca. 200 m n.v.) gore Dolac najden mrtev koconogi čuk Aegolius funereus, mlad (2Y) samec. Najdba je zanimiva, ker gre za enega redkih podatkov o pojavljanju koconogega čuka na obalnem predelu Hrvaške. Doslej so bili za to območje potrjeni le štirje podatki, tri iz okolice Senja in en iz okolice Dubrovnika (Zagospom), in vsi starejši od 70 let. Konconogi čuk je na Pag najverjetneje migriral s svojih najbližjih gnezdišč na Velebitu. Znano je namreč, da je del populacije koconogega čuka, posebej mlade ptice in samice, zunaj gnezditvenega obdobja nomadski. Odpira se vprašanje habitata, v katerem je ptica bivala na Pagu, sajnaj bi koconogi čuk tudi zunaj gnezditve izbiral potencialni gnezditveni habitat, to pa so v Evropi mešani in iglasti gozdovi višjih leg. Kadaver z zdrobljeno lobanjo je bil najden pod peto vetrnico v vetrni elektrarni Ravna 1. Vzrok smrti je bil trk z vetrnico. Po naših podatkih v tej vetrni elektrarni ne opravljajo študije vpliva elektrarne na smrtnost ptic, kar bi bilo po tujih priporočilih in upoštevajoč omenjeno najdbo nujno potrebno.
