Urban ecologists have long wondered how both crows and ravens can thrive in the same cities while feeding on many of the same resources. According to conventional wisdom, one species should eventually displace the other after outcompeting it for food. Yet both birds continue to expand across large metropolitan regions. Field surveys and casual observations have produced many partial explanations, but none has fully solved the puzzle of coexistence. If crows and ravens truly overlap in diet and habitat, why does one not prevail? Researchers still lack a satisfactory account that explains how closely related scavengers persist side by side in crowded urban landscapes.

Ornithologist Priya Raman and colleagues connect this coexistence to fine scale separation in time and space. Using GPS tags, camera traps, and stable isotope analyses, they found that crows concentrate around schoolyards and parks during daylight, while ravens favor early morning loading docks and taller rooftops. The birds also differ in flight height and perch choice, which limits direct encounters at food sources. Raman's team concludes that apparent overlap masks reduced interaction. In cities, microhabitat and daily schedule differences likely make head to head competition between crows and ravens much less common than previously assumed.
Based on the texts, how would Raman and colleagues (Text 2) most likely respond to the "conventional wisdom" discussed in Text 1?
