For those not yet in the know, this crow is attempting something called kleptoparasitism, a foraging strategy where instead of getting your own food, you steal someone else’s!
There are two types: obligate, meaning you steal all your food, and facultative which means you do it opportunistically. Most animals are facultative. Sometimes it’s done on other species sometimes within your own.
This crow is deploying a strategy of trying to bother/distract the osprey into an opportunity where it can take the food. This is very common in corvids!
Other common avian kleptoparasites are bald eagles, frigatebirds, lots of gull species, oystercatchers, and many others!
