Eurasian Hobby Falco subbuteo: A review of recent records from Western Australia and Australian external territories.

All Australian records of the Eurasian Hobby Falco subbuteo are summarised. Before 2016, the only Australian records of the Eurasian Hobby were on external territories to the north-west of the mainland. Each year between 2016 and 2021 a single Eurasian Hobby was observed as an austral summer visitor to the Swan Coastal Plain in south-western Western Australia. These sightings involved an adult in 2016, 2019 and 2020, and single immature birds in 2017–2018. The age of the Hobby seen in 2020–2021 was undetermined. As it appears that multiple individuals have been recorded across years, it is likely that the species is now more than just an accidental vagrant to Australia. [ABSTRACT FROM AUTHOR]
