Abstract
I found a young cuckoo (Cuculus canorus) in the nest of the black redstart (Phoenicurus ochruros) in the viticultural area of Andra{evec (46°00’N, 15°57’E), in north-western Croatia, on June 15, 2004. The nest was situated on an outer wooden beam of a building in a vineyard.

Abstract
We investigated the ability of surface- and cave-dwelling P. mexicana females to localise conspecific males in light and darkness. Females of both populations showed a predilection for the male in both experiments. Non-visual association behaviour in darkness in the surface form can be viewed as a pre-adaptation to cave life in this species.

Abstract
As in other European countries, there are some indications that the polecat population in the Republic of Croatia is declining. Gamekeepers rarely hunt polecats and if they do it is mainly at the request of landowners. Along with maltreatment, their poor cultural image, accidental poisoning and road traffic accidents can probably be marked as the main causes of the declining polecat population. In order to acquire firm data on the number of polecats, their behaviour and social organization, further studies are to be encouraged. Based on the results of these studies, a recovery plan should be arranged. This plan must include the creation of a positive image for polecats at all levels of society and the prevention of a further decline in the polecat population brought about by continuing inappropriate exposure of poisoned baits.

Abstract
A new cave dwelling species of Euconnus (Tetramelus) Motschulsky is described from the Croatian cave »Bazgova~ka Jama«. The relationship of the new species to the species-groups longulus and oblongus is briefly discussed and the occurrences of Tetramelus in the former Yugoslavia are concisely listed.

Abstract
In field research into Dugi otok outside the confines of Tela{}ica Nature Park, and two northern islets (Mali Lagan, Veli Lagan) we found 35 species of terrestrial snails with shells. Of these, 33 species had been recorded in the literature with reference to Dugi otok, including the surrounding southern islets that form part of Tela{}ica Nature Park. Cepaea vindobonensis and Hygromia cinctella are species that have been newly found. Our investigations did not reveal 10 species that are cited in the literature. We considered that two taxa (Delima blanda conspurcata, Cepaea nemoralis) do not live on the island and the islets stated, while the remaining eight taxa (Vallonia costata, Granopupa granum, Truncatellina claustralis, Agathylla lamellosa, Delima edmibrani, Testacella scutulum, Cochlicella acuta, Chilostoma setosa) are held to be certain denizens of Dugi otok, which we did not find because our investigations were not systematic enough or because they do not live outside the area in which they were recorded (Tela{}ica Nature Park). Among the species that attract particular attention are: Delima edmibrani, which is narrowly endemic to Dugi otok; Agathylla lamellosa, of which this is the northernmost finding site; Chondrina spelta ventilatoris, because it is the westernmost finding site; and Testacella scutulum and Paralaoma servilis, because they are found so seldom in Croatian malacofauna. Dugi otok, with the surrounding islets and rocks mentioned, has a total of 43 species, which constitutes, in comparison with other islands of the eastern Adriatic, a relatively rich terrestrial malacofauna.

Croat., Vol. 14, No. 1., 1–28, 2005, Zagreb. Terenskim istra`ivanjima Dugog otoka izvan granica PP »Tela{}ica« i dva sjevernije polo`ena oto~i}a (Mali i Veli Lagan) na{li smo 35 vrsta kopnenih pu`eva s ku}icom. Od toga su 33 vrste bile u literaturi zabilje`ene za Dugi otok uklju~uju}i i okolne ju`ne oto~i}e koji ulaze u sastav PP »Tela{}ica«. Novona|ene su Cepaea vindobonensis i Hygromia cinctella. Na{im istra`ivanjima nismo na{li 10 vrsta zabilje`enih u literaturi. Za dvije svojte (Delima blanda conspurcata, Cepaea nemoralis) smatramo da ne obitavaju na otoku i navedenim oto~i}ima, a preostalih 8 (Vallonia costata, Granopupa granum, Truncatellina claustralis, Agathylla lamellosa, Delima edmibrani, Testacella scutulum, Cochlicella acuta, Chilostoma setosa) smatramo sigurnim stanovnicima Dugog otoka koje ili zbog nedovoljne sustavnosti istra`ivanja ili zbog toga {to svojte ne obitavaju podru~ja izvan PP »Tela{}ica« Croatian Natural History Museum, Demetrova 1, Zagreb, Croatia 2 [tamol, V. & Klete~ki, E.: Terrestrial snails (Mollusca: Gastropoda terrestria) of Dugi otok (Croatia) nismo na{li. Me|u vrstama treba istaknuti Delima edmibrani kao stenoendem Dugog otoka, Agathylla lamellosa zbog najsjevernijeg nalazi{ta, Chondrina spelta ventilatoris zbog najzapadnijeg nalazi{ta, te Testacella scutulum i Paralaoma servilis zbog rijetke pojavnosti u hrvatskoj malakofauni. Dugi otok s navedenim okolnim oto~i}ima i hridima broji ukupno 43 vrste {to predstavlja, u usporedbi s drugim isto~nojadranskim otocima, relativno bogatu kopnenu malakofaunu.
