Celem pracy była ocena lęgów sokoła wędrownego w wybranym gospodarstwie
indywidualnym na terenie województwa mazowieckiego. Badania przeprowadzono w latach
2006–2011 na dwóch parach sokołów wędrownych w wieku 7–12 lat. Od pary hodowlanej
podbierano jaja, prowokując ją do ponownego składania jaj. Przeprowadzoną w pracy analizę
lęgów oparto na następujących wskaźnikach: liczba zniesionych jaj przez dwie samice
w systemie dwóch lęgów w jednym roku, procent zapłodnienia jaj, procent wylęgu piskląt.
Ponadto w 2010 roku przeprowadzono porównanie wyników lęgów pochodzących z inkubacji
sztucznej i lęgów naturalnych. Samice z obu par w każdym z dwóch lęgów łącznie znosiły
maksymalnie do 8 jaj. Lepsze wyniki lęgu uzyskiwano z I lęgu. Z I lęgu uzyskano również
większy odsetek wylęgu piskląt z jaj zapłodnionych, w porównaniu z lęgiem II. Nie stwierdzono
żadnych różnic pomiędzy wynikami lęgu naturalnego i inkubacji sztucznej. W badanym okresie
uzyskano od obu par sokołów łącznie 18 piskląt.
The purpose of this work was to evaluate peregrine falcon clutches on a selected private farm located in the Mazovian Province (Voivodeship). Studies were conducted on a breeding farm located in the Mazovian Province over the years 2006–2011. Observations were made of two pairs of peregrine falcons. The eggs were removed from nests to make each breeding pair re-nest. Analysis of clutches presented in this paper was based on the following indicators: number of eggs laid by two females in a system of two clutches per year, % fertilised eggs, % hatched chicks. Moreover, in 2010, results of natural and artificially incubated clutches (the second clutch of pair Y) were compared.The maximum number of eggs per hatching laid by the females in a two-clutch system was eight. The better results were obtained for clutch 1. What is more, clutch 1 had a higher percentage of chicks hatched from fertilised eggs, compared with clutch 2No differences were found between the results of artificial and natural incubation. A total of 18 chicks were obtained from both the pairs through the study period.
