Broedgeval van vermoedelijke Noordse Kwikstaart bij Spaarndam in 2008
Roy Slaterus Breeding of presumed Grey-headed Wagtail near Spaarndam in 2008From 21 April 2008, a male Grey-headed Wagtail Motacilla thunbergi (or possibly a hybrid) was present near Spaarndam, Noord-Holland, the Netherlands. During early May it appeared to be paired with a female \'yellow wagtail\', probably a Blue-headed Wagtail M flava. The identification of the male was based on its mostly dark grey upperhead, with a short, white supercilium behind the eye. The possibility that it was a hybrid could not be fully excluded; the rather wide supercilium (for Grey-headed), the pale lower part of the eye ring and only a few dark spots on the breast may have been indications of hybridization. The female had an obvious supercilium, a white eye ring and pale spots on the ear coverts which suggested Blue-headed; however, the underparts appeared less yellowish than typical for that species. The pair raised at least two young and was last seen on 20 June. In 2009 the male returned - probably as early as 9 April - but it appeared to be unpaired. Previously, territorial males Grey-headed in the Netherlands were reported in 1975, 1977 (two), 1979 and 1994, but breeding was not documented in these cases. The species\' nearest breeding areas are situated c 700 km north of Spaarndam in southern Norway. Roy Slaterus, Bervoetsbos 71, 2134 PM Hoofddorp, Nederland |

Siberische Taling in regio Amsterdam in mei 2006
Leon Edelaar Baikal Teal in Amsterdam region in May 2006On 18 May 2006, an adult male Baikal Teal Anas formosa was discovered late in the evening near Ouderkerk aan de Amstel, Noord-Holland, the Netherlands, and seen by c 15 birders. Next morning, it was gone but it was relocated on 21 May at Polder IJdoorn, Noord-Holland, c 15 km north-east of the first site. It was last seen here in the morning of 22 May and visited by 100+ birders. Both sites are flooded meadows with low water levels. Already on 14 May, probably the same male was reported at Langeraar, Zuid-Holland (15 km south-west of Ouderkerk aan de Amstel), but this sighting was submitted without sufficient documentation and could therefore not be accepted. The bird was unringed, had undamaged plumage and showed no aberrant behaviour. Identification was straightforward and there were no indications of any hybrid influence. It was accepted by the Dutch rarities committee (CDNA) as the ninth record and the first since 1962. In recent years, several proven escapes have been reported in the Netherlands. In November 2005, a first-winter Baikal Teal was shot in Denmark. Stable isotope analysis of old and newly grown feathers of this bird showed that it almost certainly originated from Siberia, Russia. This record supports the CDNA policy to accept Baikal Teals that do not show rings, wing damage, hybrid plumage traits and/or aberrant behaviour as (possibly) wild birds.
