 abstract={Five bird species (Great, Blue and Coastal Tits, Redstart, Tree Sparrow) nested inside vertical metal pipes of fences in Warsaw suburbs (central Poland). It appeared to be the main breeding site for a Great Tit - nearly 80% of the nests of the local population. The preferred diameter of the pipes depended on the size of the species (mainly on the length of tarsus). It was the highest in Great Tit and the lowest in Blue Tit. Great Tit built its nests significantly deeper (up to 1.7 m from the upper edge) than the remaining species. The mean number of fully feathered nestling per nest with success was lower in pipes than in nest boxes. Such a nest location is a local adaptation of birds living in highly urbanised area, where natural cavity breeding sites are scarce.},
