Bankovics Attila: Fehérhátú fakopács (Dendrocopos leucotos) a Bakonyban

gen stellt Verfasser folgendes, auf dieses Paar sich beziehendes fest: 1. Das Weibchen füttert öfters als das Männchen. In der Gesamtbeobachtungszeit von 5 Stunden und 10 Minuten brachte das Weibchen 23 Mal, das Männchen nur 9 Mal Futter ihren Jungen. 2. Die Nahrung wurde aus einem ungefähr 300 m grossen Gebiet vom Linden-Eschen-Felsenwald und Buchen-Hochwald zusammengetragen. 3. Auf den 1—2 Tage alten Jungen sassen die Alten auch noch tagsüber abwechselnd, nach einer Woche aber nicht mehr. Die ausser der Brutzeit beobachteten erwachsenen Vögel im Bakony-Gebirge suchten ihre Nahrung in erster Linie an den Stämmen und Aesten der vermoDendrocopos leucotos is the rarest of woodepeckers in Hungary. It has been known until now only from the Zemplén, Bükk, Mátra and Börzsöny Mts. There is literature data on its nestling in the Piedmont of Alps (CHERNÉL, 1899). Thus, from the Transdanubia it has not come forward in this century, this is why its occurrence in the Bakony Mts. is so interesting. The author first observed Dendrocopos leucotos on the 26th of December, 1971 on the highest point of the region (Kőris-hegy: 704 m). Since he saw it in ten other occasions and on the 20th of April, 1972 he was able to confirm its nestling here, too. The paper makes a comparison between data recorded in the Bükk Mts. and here in the Bakony Mts. The species was found in both regions in ecologically similar biotopes. Nidobiological observations were made in the case of the pair nestling in the Bakony Mts. especially with repect to the intensity of nourishing the nestlings, these are shown in tabulated form. The author established the following for this nestling pair: 1. The hen feeds more often than the cock. During an observation period of five hours and ten minutes the hen brought food for the young 23 times the cock only 9 times. derten oder vertrockneten Buchen (Fagus süvatica), mit Vorliebe an den einzeln vorkommenden, ausgetrockneten Bergulmen (Ulmus scabra). An anderen Baumarten sowie an Eschen (Fraxinus excelsior), Linden (Tilia platyphyllos), Hainbuchen (Carpinus betulus) und Steineichen (Quercus cerris) usw. sind sie auch oft zu beobachten. In forstwirtschaftlicher Hinsicht ist es eine ausgeprochene nützliche Art. Da diese Art in ganz Europa selten ist und im Gebiet von Transdanubien das einzige Vorkommen im Bakony-Gebirge ist, empfiehlt Verfasser, dass die als Nistplatz dienenden Waldteile am Köris-Berg als geschützt erklärt werden.

The 1—2-day old nestlings were alternately sal on by the adults even during the day until they reached the 6th or 7th clay. The adult birds were observed outside of the nestling period to collect their food primarily on moulding or dry beech (Fagus süvatica) trunks or branches but they especially frequented lonely dead wych-elm (Ulmus scabra). Other tree species were also visited like the common ash (Fraxinus excelsior), big-leaf linden (Tilia platyphyllos), hornbeam (Carpinus betulus), the Austrian oak (Quercus cerris), etc. This species is expressedly useful from sylvicultural point of view. Owing to the fact that this species is rare throughout Europe, and the Bakony Mts. is its only nestling place in Transdanubia, the author proposes to make the nestling areas of this species a nature reserve on the Kőris Mountain.
