Over 11 years, the presence of bird species detected within a garden in Kaikōura, New Zealand, were recorded on a weekly basis. Of the 19 species, Eurasian blackbird (Turdus merula merula), house sparrow (Passer domesticus domesticus) and common starling (Sturnus vulgaris vulgaris) were most commonly detected followed by silvereye (Zosterops lateralis), the most commonly detected native bird. New Zealand falcon (Falco novaeseelandiae), Australian magpie (Gymnorhina tibicen) and California quail (Callipepla californica brunnescens) were each seen once. Others recorded were bellbird (Anthornis melanura melanura), chaffinch (Fringilla coelebs), common redpoll (Carduelis flammea), dunnock (Prunella modularis), European goldfinch (Carduelis carduelis britannica), European greenfinch (Carduelis chloris), grey warbler (Gerygone igata), red-billed gull (Larus novaehollandiae scopulinus), song thrush (Turdus philomelos), South Island fantail (Rhipidura fuliginosa fuliginosa), yellowhammer (Emberiza citrinella) and welcome swallow (Hirundo neoxena neoxena). Ten species exhibited significant seasonal variation; 4 showed significant increases and 2 decreases over the 11 years of the study. This study has shown that simple presence/absence observations of a species on a weekly basis can provide an index of numbers, and demonstrate seasonal movements and medium-term changes of bird species within an urban garden.
