Spatial distribution and breeding success of striated caracara of Sea Lion Island, Falkland Islands (2013-2019)

The dataseries includes data on Striated caracara (Phalcoboenus australis) taken from a regular monitoring study carried out at Sea Lion Island from 2013. Almost all nesting pairs have been located and each nest is monitored along the whole breeding season to estimate nesting, breeding and fledging success. Apart from nest monitoring opportunistic data on social and parental behaviour, diet, and reaction to human beings have been collected. All together, the Sea Lion Island population of caracaras has increased from the first survey of the 90s, but in recent years it has been almost steady, with 14 to 18 pairs successfully nesting every year. Further information is available on the research group website, www.eleseal.org.

Lineage	Field work on caracaras was carried at Sea Lion Island during the breeding season from 2013 to 2019. The whole island was searched to identify caracara nests, using adult reaction to us as a first guidance to locate nests. Most nests were rather easy to locate. Caracara nests were mapped using navigation-grade GPS receivers. All nests were surveyed weekly until fledging, taking note about the nest location, substrate and general habitat. Ad libitum notes about the reaction of adults, their general and vocal behaviour, and the interaction between adults and chicks were also recorded.

Accuracy	Accuracy of mapping by navigation grade GPS (e.g. daily mapping of males) is 5 metres; accuracy of mapping by survey grade GPS is submetric to decimetric. Collection of all other data is compliant to usual research standards, and a great effort is put to guarantee high repeatability of data.
