Journal Article
TL;DR: The raw data suggest a general decline from the 1985 to the 2000 census, and from 2000 to 2013 the numbers of active nests have generally increased as discussed by the authors, indicating that the number of nests has generally increased.

Journal Article
TL;DR: If it is confirmed that Pied Crows are having substantial negative impacts on prey and/or competitor species, as seems to be inevitable where the abundance of crows has increased massively, remedial action to prevent or minimise damage should be taken.

Journal Article
TL;DR: Early breeding results in extended breeding seasons with more breeding attempts and probably more fledged young than in rural areas as discussed by the authors, which results in a longer breeding season with more successful young.
