Tapfer Dezső: Megfigyelések a kerecsensólyom keleti-bakonyi fészkeléséről

Arrival of the saker falcon in late winter After weeks of steady mild weather in late January and early February the saker falcon used to return to the Bakony in late February or early March. An exception is the Northern Bakony where the snow used to stay frequently even in late March. In this part of the mountain the setting of saker falcons has not been ascertained thus far. In case of their early return the saker falcons of the East^Bakony have their sitting complete in the first half of April and in early May the young break the shell. Choosing the nesting sites, behaviour during the breeding period Of the 11 saker aeries in the Bakony 7 are rockcavities, 4 are clefts thinly, just partly covered overhead. The clefts usually look to he south or south-west, sometimes to southeast-east. The saker falcons occupying nests deserted by buzzards, kites and hawks choose always nests built on high crests that can be approached by direct flight. They never renovate twig-nests, on the contrary they rather deepen and damage them. They stick to well-protected airies for decades, returning to them faithfully. The saker falcons are very sensitive against any kind of disturbance: they quit even unhatched eggs or incomplete sittings. On the other hand, they cling very much to their nestlings. Lying in wait one can observe the elders how they feel the watching human eyes, they do not stay with the nestlings for a longer time, just drop the prey near them and fly away. The principal feed of the saker falcons is the souslik, occasionally the hamster and the bird caught in flight. A cool, rainy and snowy April (e. g. 1959, 1960) can distroy the saker sittings laid in early April. For the same reason, in 1963 breeding was delayed На основании наблюдений, проводившихя во течение трех десятилетий над балобаном (Falcc cherrug Gray), автор сообщает наиболее важные данные о местах в Восточном Баконе, где обитает и гнездится эта птица. Автор показал на карте и в таблицах ряд найденных им и повторно прослеженных мест в Баконе, где гнездится балобан (всего до настоящего времени их обнаружено 14). На основании длительного наблюдения в течение многих лет, автор в своей статье подробно занимается экологией балобана, особенно вопросом выведения и воспитания птенцов. Им также приводятся данные о питании, биологии, кольцевании, наблюдения о until May in all the places where in previous years the sitting used to be complete in the first week of April. Rearing the nestlings At the beginning the hen-bird broods alone. In general, beginning with the third week, she is relieved by the cock regularly. The cock saker weighs less than the often 1,5 kg hen, but this weight difference is hardly noticeable from the build of the birds when flying. It must be underlined that during the breeding time the sitter and later the nestlings feed almost exclusively on souslik. They catch the souslik by flying low and snatching it from the ground. Around the nesting places of the Bakony sakers agricultural areas rich in sousliks alternate with rolling poor grazing lands abounding in souslikholes. The saker nestlings are confined to the nest for 4—5 weeks. In case of a normal hatching they take flight in the first half of June. In general they still spend a few weeks with the elders and they learn from them in the vicinity of the nesting place the tricks of hunting. Migration of the saker falcons In the warm summer months part of the saker falcons of the East-Bakony move by day time near the fish-ponds on the skirts of the Bakony to catch there souslik and small water-game. Toward autumn migrant sakers of more remote areas can be seen around the fish-ponds. In September also sakers of passage can be seen among the sakers on the fringes of the Bakony. In the case of a mild autumn the old saker falcons can be found in the vicinity of their Bakony nesting sites even in October. For the severe winter months the saker falcons of the Bakony migrate to the mediterranean areas of the South. Dezső Tapfer перелете, которые проводились на месте, где водится эта птица. Восточный Баконь является местом распространения балобана, он простирается в около двухстах километрах от западной и северной границы, в то же время самая западная часть его является местом, где вид этот постоянно гнездится. Распространение балобана в восточной части Из 14 мест, где гнездится балобан, 11 расположены на скалах, 3 — на деревьях (в гнездах, оставленных хищниками).
