Hi.

I can add the pdf file of a very interesting paper on melanism in birds published by Hein van Grouw, which is really useful.

Best regards.

Hi Jack,

That is a hard question, especially with so much conflicting information out there. I was interested in a similar topic a while back and found a solid review on albinism (and related variations) in wild vertebrates--it will be a great place to start (see attached).

Good luck!

Best,

Danny

Hi again.

I attach a paper on albinism and other chromatic aberrations in birds, published by Hein van Grouw, really useful and interesting.

Best regards.

Hi,

I agree with Ruben. Hein van Grouw is the expert in this topic. You can find more papers from him here on his RG.

Good luck!

Apologies for the delay in replying, a big thank you to everyone who has commented with suggestions and/or links to relevant publications. I would ordinarily reply to everyone's comments individually, but I'm not sure whether this is possible (...I am new to ResearchGate)!

Please keep your comments coming - I'm still looking for information regarding atypical pigmentations in wild reptile, fish and amphibian populations.

Cheers

Dear Jack,

Regarding to amphibians, I can add a note we published many years ago about an individual of Hyla meridionalis with atypical, aberrant coloration. Perhaps it may be of your interest.

Best regards.

Hi again.

I found in my files the attached article, centred in a collection of birds of a Museum of Natural History in Slovakia. It may be interesting...

Best regards.
