I am extremely pleased to discover that you have uploaded a photograph of this taxon, along with all the other unusual owl species you have now uploaded to the gallery. This species is quite a recent loss from European collections - the last individual having passed away at Olmen Balen in 2012 - but until you uploaded this photograph and the older one taken at Wassenaar there were no images of the species within the Zoochat gallery. As such I would be very interested to hear more about how you came by these photographs!
