New Zealand falcons (Falco novaeseelandiae) routinely feed on burrow-nesting seabirds (petrels: Procellariiformes) at several sites. As petrels are rarely present on the colony surface during daylight, and falcons are considered to be diurnal hunters, there has been much speculation about how falcons are able to capture petrels. We present evidence that New Zealand falcons are able to hunt petrels in forest at night, and also enter burrows during the day to extract chicks. These are novel hunting behaviours for falcons, and further increase the broad range of hunting strategies documented for New Zealand falcons. While these hunting methods may be used by only a few individual birds, they can produce high prey-capture rates.
