Search for: [Abstract = "117 nests of Red\-breasted Flycatchers in Białowieża primeval forest \(NE Poland\) are characterised. Most nests \(79%\) were built in Hornbeam Carpinus betulus and Lime Tilia cordata. Three types of nest sites were distinguished\: chimney shaped \(26.4%\), half\-cavities \(46.4%\), or shelves — the nest is wedged under a piece of bark against the main trunk \(27.3%\). Most cavity entrances were exposed to the south. Compared to other species of secondary cavity nesters in Białowieża National Park, Red\-breasted Flycatchers used cavities of a different shape, with a smaller bottom area, and at a relatively low height above the ground \(>>= 4.9 ą 3.12 m\). Nesting trees had a smaller diameter \(>>= 31.2 ą 21.4 cm\) and were more often dead \(27%\) than trees used by other secondary cavity nesting species. Only four nest sites were used in consecutive seasons."]
