Crow Omnivory and Misconceptions

You might think crows are the ultimate omnivores, eating everything in sight. But, surprisingly, research shows their diet is often misunderstood. While they do adapt to urban environments, scavenging for food sources like trash and leftovers, their diet is more complex than we think. Let’s set the record straight on crow adaptation and scavenging behavior.

Kelp Gull Whale-Eating Behavior

Kelp gulls, also known as Dominican gulls, aren’t picky eaters. They breed on coasts and islands in the Southern Hemisphere and have a reputation for being opportunistic feeders. They’ll scavenge landfills and happily feast on human garbage.

But it’s their predatory behavior that’s particularly intriguing. Kelp gulls have been observed attacking and feeding on southern right whales since the 1970s. They target vulnerable calves and mother-calf pairs, landing on the whales’ backs and gouging out skin and blubber with their powerful beaks. These attacks often result in large, open wounds, some up to half a meter in diameter.

While the number of attacks has increased over the years, the gulls’ technique remains the same. They usually strike when the whales are resting or surfacing to breathe, exposing their backs. The gulls then repeatedly widen the wounds by pecking and digging deeper into the skin and blubber, sometimes merging adjacent lesions to create elongated wounds.

These attacks may have contributed to the unusually high number of whale calf deaths in recent years. While the exact cause is still unknown, the stress and injuries inflicted by the gulls could be compromising the whales’ health and survival.
