Peregrine falcons on ORLEN Unipetrol Group’s chimneys get ready for nesting. Now also in Pardubice. Watch them online!


This year is the 13th year of the joint monitoring of peregrine falcons by the refining and petrochemical group, ORLEN Unipetrol, and the ALKA Wildlife association on ORLEN Unipetrol’s production premises. Forty-one chicks of this endangered species have been born on the chimneys in Litvínov, Kralupy nad Vltavou, and Neratovice since 2011. Ornithologists have newly prepared a nest box for the peregrines on the chimney of Paramo Pardubice. The courtship and nesting preparations usually start at the turn of February and March. In addition, cameras are installed on four chimneys, i.e., the life of peregrine falcons can be watched online at

“This is the 13th season of our support of peregrine nesting at ORLEN Unipetrol. The public can traditionally watch their stories in a live broadcast​ from four chimneys in three locations on our production premises. Peregrine falcons regularly nest on two chimneys in Litvínov and one in Kralupy nad Vltavou and one in Neratovice. We have installed one box on a chimney in Paramo Pardubice this year. We believe this season to be successful for peregrine pairs and hope they will nest in our boxes and raise their young,” comments Katarzyna Woś, Vice-Chair of the Board of Directors at the ORLEN Unipetrol Group.  

The live broadcast from the nests gives the public a unique opportunity to learn more about this precious bird of prey. The boxes are installed at a height of more than 100 metres because peregrine falcons seek as high places as possible to nest and have absolute peace and an excellent view. Ornithologist Václav Beran from the ALKA Wildlife association prepares the boxes for the entire season every year before the peregrine nesting and courtship. “We repainted the nesting boxes in autumn and added a new artificial grass carpet and keramzit. Thus, peregrine pairs have their hideaways ready for the spring season. The period of courtship to raising the chicks usually starts at the turn of February and March, i.e., the season really starts now. We have already observed peregrines on the chimneys in Litvínov, Neratovice, and Pardubice. The warmer weather could mean they will start nesting earlier.” 

A female peregrine falcon usually lays one to four eggs and sits on them for about 30 days until the eyases are born. Then, a real whirl and rush start for the parents because the offspring require regular care and feed. Their substantial menu includes pigeons, gulls, various small birds, and bats. Ornithologists ring the chicks after about three weeks to clarify the birds’ origin in the Czech territory in the future. They also record the chicks’ gender when seeing the nest. In June, the chicks are strong and experienced enough to leave the nest. Young raptors leave home to acquire experience and look for their own territory after two to three years, where they can provide for themselves and bring another generation of this endangered bird species into the world. The life span of peregrine falcons is up to 20 years, and they return to their popular nesting location all their life. These birds disappeared from our nature in the 1960s, but their numbers slowly continued growing in the new century. There are about 130 peregrine falcon pairs in Czechia now.
