Oriental Turtle Doves in the Netherlands in 2009-20 From late 2009 to early 2020, 11 Oriental Turtle Doves Streptopelia orientalis have been observed as (presumed) wild birds in the Netherlands. In this paper, 10 records from 2010-20 are described in detail (the first, an adult at Wergea, Friesland, from 23 December 2009 to 3 April 2010 has already been published in a separate paper). The additional records were on a ship at the North Sea, Continentaal Plat, c 50 nautical miles north-west of Texel, Noord-Holland, on 16 November 2010 (first-year); on Vlieland, Friesland, on 20 October 2012 (first-year); on Schiermonnikoog, Friesland, on 11-13 October 2013 (adult); at Zoutelande, Zeeland, on 14 December 2014 (age uncertain); at Vlaardingen, Zuid-Holland, from 30 December 2014 to 25 February 2015 (adult); on Vlieland on 30-31 October 2016 (first- year, ringed); at Limmen, Noord-Holland, from 22 January to 9 March 2019 (second calendar-year); at Emmen, Drenthe, on 9 and 21 February 2019 (adult); at Sneek, Friesland, from 28 December 2019 to 11 March 2020 (adult); and at Alkmaar, Noord-Holland, from 14 February to 31 March 2020 (presumed adult). All birds were discovered in autumn or winter. Four of them stayed for a longer period, up to more than three months. For each record, the circumstances of the discovery and a plumage description is given and the identification and ageing of each bird is discussed. The birds from 2009-10, November 2010, 2013, 2016 and two birds from 2019 (at Limmen and Sneek) were accepted as the subspecies S o meena (Rufous Turtle Dove); the bird at Alkmaar in 2020 most probably also belonged to meena.For the other birds, it was not possible to determine the subspecies with certainty, although the bird at Emmen (2019) showed characters indicative of S o orientalis (Eastern Oriental Turtle Dove). All birds but one have been accepted by the Dutch rarities committee (CDNA); the bird from Alkmaar in February-March 2020 still awaits acceptance. In addition, there have been two observations of proven escapes, one in December 2008, which was a ringed bird escaped from a nearby aviary, and one in January 2014 wearing a red ring.
