Some Hawaiian honeycreepers’ long curved bills are the perfect implement for drawing sweet nectar from deep within a lobelioid flower. As birds reach into flowers to access the nectar stored near the base, their bills can brush against the lobelioids‘ pollen-bearing structures, making hungry honeycreepers important pollinators. But some of these specialized honeycreepers have gone extinct. Shorter-billed species can now “rob” nectar — without contacting the flower’s pollen-bearing structures — from the endangered flowers. A UW-led team used motion cameras to gauge how often nectar robbing occurs. The results, published Aug. 6 in Ecology and Evolution, reveal both nectar robbing…
