230 Iz ornitolo{ke bele`nice / From the ornithological notebook ni bila pretirano pla{na, saj je dovolila opazovanje z vsega 10 metrov razdalje. Sicer so tega dne na Blatu kraljevale predvsem razli~ne vrste ~apelj, med katerimi je bilo 11 ~opastih Ardeola ralloides. Na poplavljenem pa{niku se je med njimi prehranjevala tudi svatovsko obarvana plevica Plegadis falcinellus. Rde~egrla cipa je na Hrva{kem redka vrsta, za katero je le nekaj starej{ih podatkov iz ju`ne Dalmacije [Kralj, J. (1997): Ornitofauna Hrvatske tijekom posljednjih dvjesto godina. – Larus 46: 1–112].

Na robu skupine je bil vrabec, ki je imel rjavo glavo in bela lica. Ob pomo~i priro~nika smo ugotovili, da gre nedvomno za italjanskega vrabca. Sicer so kri`anci med doma~im in travni{kim vrabcem pogosti, kjer koli se ti dve vrsti sre~ata [Svensson, L. & Grant, P. (1999): Bird guide. – Harper Collins Publishers Ltd., London], vendar kri`anci iz Dalmacije niso poznani [Rucner, D.

Dne 16.2.2002 zjutraj je avtor v bli`ini hotela Jezero v starej{em bukovem sestoju opazoval jato pino`, ocenjeno na 300.000 osebkov, ki so se hranili na gozdnih tleh. Jati pino` je bilo prime{anih {e vsaj 3000 dleskov. In the winter 2001/2002, invasion of Brambling was registered in Central Europe. In this context, the observation of this species in Plitvice National Park is no doubt interesting. On 16 Feb 2002, during light snow, intensive calls of finches were heard at 7.30 a.m. from Jezero Hotel. Immediately below the hotel, more then 10 flocks of Hawfinches, each numbering 30 – 60 birds, were seen on the top of Beech trees Fagus sylvatica. Following the National Park visitor road towards the northeast, the first large flock of Bramblings was observed feeding on the slopes. During a 20 minutes observation, the flock moved in a 100 m wide corridor with a rate of 3000 to 4000 birds per minute. The total size of the Brambling flock was estimated using the average density of feeding finches on the forest floor. A square meter was used by 5 to 20 birds searching for the beech seeds in the thick layer of leaves, which were here covered only with a thin layer of snow. The area covered by feeding Bramblings was at least 300 m long and 100 m wide. Calculating an average of 10 birds per square meter and an area of over 3 ha, the size of the Brambling flock consisted of at least 300,000 birds. In this huge flock, groups of Hawfinches with a total number of at least 3000 birds were also seen. The observation indicates great value of the preserved old forest stands on the northwestern slope below the main road in the park during severe winter conditions.

The pits are suitable breeding sites for a number of bird species, the most conspicuous among them being the Great Crested Grebe. Mating behaviour by a single pair was observed for the first time on 15 Apr 2001 on the largest pond. In that year, breeding was confirmed on 20 May, when a pair with chicks was observed. In 2002, two pairs bred within the complex, rearing two young each, which were eventually seen on 28 Aug. In 2003, a pair with 5 chicks was registered, while
