Mornings, so the time from the sunrise, around 9-10 o’clock, are the best time for bird watching of the majority of species. However, some species, e.g. the aquatic warbler, the blackbird, the song thrush or the European Robin are active about 1-2 hours before the sunset till the twilight. There is also a group of nocturnal birds which can be heard or luckily seen, e.g. the Eurasian eagle-owl, the tawny owl, the long-eared owl, the spotted crake or the corn crake. Bird breeding time begins at the end of February and can last even to October, however, the most important time for birds encompasses the period from April till the half of July.
