As regards the speculum colour, this will change depending on the angle of the light falling on it as it is a structural colour.

Sorry, I don’t think these pics attached properly first time round, trying again:

 

Some queries from the Karen Club bird walk, 3 October 2014:

 

1. Squacco / pond heron: which species?

 

2. Yellow-billed duck with both green and blue speculums together: any feedback on this unusual juxtaposition?

 

Excellent photos from Gail Paul, thanks so much!

 

All best, John Dawson
