Beautyful bird from North-America.
Blackburnian wharbler, 'sparrenzanger' in Dutch. In Europe - we live in the Netherlands - an rare astray, special blown in glass for the American market. Thus we made our order in the USA, at GlassBirds.com. Vere fast shipment: within two weeks we received the package, well cared for.
(Small warning: clearance costs amounts approximately $ 150 for a shipment from Minneapolis to Amsterdam, but... that's worth it!)
