Answer & Explanation:
Firstly, in "Brain Birds," Brooke Jarvis portrays crow and raven intelligence positively. She describes the birds' remarkable cognitive abilities, such as their problem-solving skills and tool-making evolution. Jarvis writes in awe of their mental capacities, saying things like, "Of all the birds on this planet, few are as smart as the members of the Corvidae family," and "these birds seem to imagine."
In contrast, "A Soft Spot for Crows" by John Wray approaches the relationship between humans and crows more subjectively. He recounts his personal experience with befriending a crow and suggests that there is something unique and special about the bird's personality. He describes the bird's assertiveness, curiosity, and intelligence and how those traits endeared the crow to him. Wray writes affectionately about the bird, saying things like, "The crow and I have become close pals."
In terms of concrete examples, Jarvis uses scientific research to support her claims about corvid intelligence. She cites various studies, such as one where ravens were found to be capable of a type of planning previously thought to be unique to humans. She also talks to scientists who marvel at the birds' intelligence and puzzling behavior. On the other hand, Wray's examples come from his personal encounters with his feathered friend. He shares anecdotes about the crow stealing a sandwich, following him on walks, and greeting him in the morning.
In conclusion, Jarvis and Wray both portray crows and ravens positively, albeit in different ways. Jarvis focuses on their intelligence, while Wray shares an anecdotal account of their personalities. Both authors use different techniques to support their views, with Jarvis relying on scientific evidence and Wray on personal experiences.
