Description:
See shots attached.

The bird was new in with 10 more Tufted duck and a hybird Scaup x Tufted on the 19th to Patsy's Reedbed pool.

Many shots taken as hybrid issues needed to be rulled out.

Paul Eele and myself studied the shots on the back of my camera and felt the bird did not show any hybrid features.

I was concerned that the flanks paled slightly to the rear but this is ok for male Ferrus Duck in litt.

 

The bird flew a short distance allowing the flight shot and revelling a white mottled brown belly patch isolated by ferrus brown plumage indicating an immature male.

During further consultation the black nail area on the bill was thought to be too large for a genuine Ferrus Duck by The Stodd, indicting previous hybrid issues being bred out...

Others and a local 'authority on ducks' commented this was within normal parameters for the species...??


The birds origin is obviously suspect as with all wildfowl on the North Norfolk Coast which is a sad situation all round. I see in the 2017 Report the species has its own Appendix 1a!??

The bird is still present at NOA Holme to the 16th January at least.

 Record accepted as genuine duck!
