Episode 75: Gynandomorphism in birds with Dr Hamish Spencer
The sex of a bird - whether it is male or female - is one of the most critical aspects of its biology. Males and females often behave differently, especially during the breeding season, and in many species, they have strikingly different plumages.
This episode features Dr. Hamish Spencer, an evolutionary biologist at the University of Otago in southern New Zealand. Hamish was recently in Colombia, where he was shown a bird that violated these rules.
Colombian ornithologist John Murillo had discovered a very unusual Green Honeycreeper (Chlorophanes spiza) on his farm near Manizales in Colombia and pointed it out to Hamish when he visited early in 2023. The bird exhibited aqua-blue male plumage on its right and grass-green female plumage on its left. The bird’s head showed the black hood of a typical male on the right, but the left side was mostly green.
This episode discusses this bizarre phenomenon, known as bilateral gynandromorphy. How did it affect this particular bird? How does it arise? How common is it? Which species has it been observed in?
The article reporting this find has colour photos taken by John Murillo and is available at journal.afonet.org/vol94/iss4/art12/
John Murillo’s video can be seen at figshare.com/articles/media/DSCN2268_MOV/23739894

    Jennifer Ackerman. A key scientific writer and a book addressing a subject - the intelligence of corvids etc - that is in science´s spotlight currently. I read her 2008 "Sex Sleep Eat Drink Dream: A Day in the Life of Your Body " The information there is a must for any person wanting to have an average knowledge of our body. Not the usual anatomy and biology stuff ... It's is a XXI century well-informed citizen must. How our body works. It explains scores of terms we hear everywhere but never get to understand: from metabolism and carbohydrates to REM (not the band) and sleep patterns. That reading really took my knowledge from the Middle Ages to the XXI century. This new work sounds worth reading. It depends on everyone's priorities and available time. Allow me to to add that, as birds, behaviour and habitats regards, Jared Diamond is my first choice, by defect. Anyway, this brief summary is really appreciated to put things in place. So, Thanks
