Story: Introduced land birds

Distribution of rooks

Distribution of rooks

Although rooks were introduced in the 1860s and 1870s in Canterbury and Hawke’s Bay, their numbers did not increase significantly until the Hawke’s Bay population boomed in the mid-20th century. Between 1999 and 2004 numbers were small in the South Island, but larger throughout Hawke’s Bay.
