That’s the finding of researchers from the University of Sheffield in the UK, published in Proceedings of the Royal Society B. (If If you’re feeling particularly science-y, the full paper is here.). The research doesn’t fully explain why “supernumerary” (as if they were extras in an opera!)
Last month, I wrote about hypothesized relationships between passerines, parrots, falcons, and seriemas , noting a need for further research on the subject. The post stimulated some great discussions but not really any additional commentary on the science behind these proposed relationships. Ringer Suh et al.
Research done quite a while back suggests that this is adaptive. Researchers have been studying song learning in birds for some time. In this study, published in the journal Proceedings of the National Academy of Sciences, a group of juvenile zebra finches was allowed to interact with an adult.
The latest scientific research places memory at the heart of decision-making. Thankfully, there’s a framework backed by brain science for getting people to act on the 10% you want them to remember. In studies like these, roughly 20 percent of people will answer “Zebra” to the last question. Using the Prospective Memory Model.
Fortunately for the honor of the species, the researchers found that kleptoparasitism was practiced at a low rate (4% of observations) while much more often, drongos captured insects disturbed by other species (41% of observations). After the two broadbill species at the start of this post, the other main attraction is a pair of two trogons.
Continuing with the topic of singing, apparently, Zebra Doves are highly valued for their singing, particularly in parts of Southern Thailand. The importance of the Zebra Doves ‘ singing is also implied in the Javanese language – apparently, “Zebra Dove” is a Javanese metaphor for a particular vocal type ( source ).
