In November 2006 a second survey of the Striated Caracara (known locally as the Johnny Rook) was carried out by Falklands Conservation. The survey report, written by Robin Woods (leader of this study), is now available. This concludes that the number of pairs breeding in the Islands stands at an estimated total of about 520 pairs, roughly the same size as in 1997-98, when the first survey was conducted.

The Striated Caracara Phalcoboenus australis is a rare bird of prey and classified as Near Threatened by BirdLife International due to its small population and restricted range. It is legally protected in the Falkland Islands, which possibly support the majority of the world population. Surveys are required to monitor the population and re-asses its world status.

The 2006 a survey team visited 18 remote outlying islands off West Falkland. The population appears to be stable, but with conservation measures in place numbers should be increasing. The factors which are keeping numbers at about 500 pairs may include lack of food in the winter, shortage of habitat or breeding sites and possibly continued predation. This survey has demonstrated the need for further detailed studies.

Falklands Conservation is grateful to all those who took part in the Survey, in particular Robin Woods, and to those who provided funding, in particular the Royal Zoological Society of Scotland and the Falkland Islands Government.
