@SimonGriffith4 @Geoffrey_E_Hill @pandolfatto @PowersPods @NickJustyn And it would never have taken flight - or been such a fun journey - without the various field teams contributed over the past decade of work finching across northern Australia.

Sparrows are often considered pests, but a new study suggests lead levels in the birds' blood could indicate if children in mining towns have been exposed to high levels of the poisonous chemical.

Why do we care? The red and yellow colors of animals play key roles in social signaling and species identity. Insight into the genetics of carotenoid color variation from natural systems help us understand how these traits evolve and the roles of natural and sexual selection. 5/n.

Genealogical reconstruction - aided with linked-read population resequencing - infers that red bill coloration is ancestral and that yellow alleles are currently adaptively introgressing between subspecies. 4/n

We report a small number of genes of large effect linked to bill color variation in this system and including CYP2J19 - an essential enzyme for the production of red ketocarotenoids - and TTC39B - a potent enhancer of carotenoid metabolism. 3/n

The carotenoid cocktail of each subspecies’ bills are distinguished by a lack of C(4)-oxidation in the yellow billed acuticauda. However, we do detect red carotenoids in this subspecies’ retinal cone photoreceptors, suggesting the bill color difference is a regulatory change. 2/n

New preprint! We examine the carotenoid composition, genetic architecture, and evolutionary history of bill color evolution in an Australian songbird called the long-tailed finch with two hybridizing subspecies that differ prominently in this trait.
