Why count birds?


The garden bird survey is a citizen science project established to monitor the population trends of common garden birds in New Zealand. It attempts to answer the question, “Are garden bird populations increasing, decreasing, or remaining stable?”

New Zealand has a number of rare native bird species that are declining in number, but we do not know the population trends of our more common native or introduced birds. We hope that the annual garden bird survey will act as an early-warning system if currently common native species start declining. Several currently common native species occur in our gardens, including fantail (shown above), tui, bellbird, silvereye, grey warbler, and kereru (native pigeon). Measuring the population trends of these species is an enormous task, which is why we need your help.
