We are back online

After quite some months of silence and absence on the Word Wide Web, we are now happy to welcome you on our new and entirely redesigned and restructured web presence. We are looking forward to step by step increasing the services of the IOU to all you ornithologists and in specific our members.

Best regards
Your team of the IOU
