From 2004 to 2006, I observed a resident group of magpies around the Stardome Observatory in One Tree Hill Domain, Auckland, New Zealand. The Observatory is located on the southwestern slope of the 48 ha park that surrounds the extinct volcanic cone of Maungakiekie, or One Tree Hill. The vegetation consists of mostly grazed pasture amongst native and introduced trees. Public can access the park by either roads or walking tracks. Members of the magpie family are not banded, but the behaviour of the birds that I have observed for 2 years suggests that they consist of the same breeding pair and their offspring. For example, the adult pair is somewhat habituated to human presence and forage around the office window sills of the observatory, sometimes even flying onto them. Breeding pairs of magpie are generally sedentary and live on permanent territories (Kaplan 2004), which is consistent with my observations. The resident pair produced 2 successful broods between 2004 and 2006.
