The superb resource that is NZ Birds Online

My go-to site for bird information is no longer the definitive field guide by Heather & Robertson, but instead NZ Birds Online. Essentially a Wikipedia for New Zealand's Birds, it gives authoritative information curated by Te Papa's ornithologist, Colin Miskelly, supported by a wealth of crowd-sourced photographs from keen birders and wildlife photographers (like myself!) One of its strengths is the ability to quickly add and modify entries as new information comes to hand, such as the recent sightings of new vagrant birds to NZ like the red-footed booby. 

I've also contributed many photos of kākā nestlings at known ages from years of nestbox monitoring at Zealandia EcoSanctuary. I often refer to NZ Birds Online when researching my native bird artworks.
