Jay 钻升 Falk

ok #introduction I'm an #evolutionarybiologist and #behavioralecologist studying how social interactions lead to biodiversity. I'm big on #socialselection, #polymorphism, #color, #genetics and #teaching /course development (queer bio woo!).

My main study organisms are #hummingbirds, especially white-necked jacobins (Florisuga mellivora), which have female polymorphism -- 20% females look like males, while the rest look different. I love them 💓

This is an illustration of the two female morphs and the male of the white-necked jacobin. Some females have a mottled gray throat and dark tail, while other females (and all males) have an iridescent blue head, white belly, and white tail.
This is Jay Falk with a white-necked jacobin hummingbird in his hand in order to take morphological measurements. His is at a wood table outside in the tropical forest of Panama. There are scattered measuring tools on the table. Falk is wearing a headlamp while looking at the bird. Birds were captured and handled under proper permits in Panama and the United States.
