Sharing a Salmon Carcass, perhaps! | Bob Armstrong's Nature Alaska

Sharing a Salmon Carcass, perhaps! shows the behavior of ravens, eagles, and gulls when feeding on a carcass in Juneau, Alaska on August 4, 2021.
I videod this event for about 1.5 hours and then extracted about 20 minutes of interesting events.
This could be used as a basis for a discussion about the behavior of these birds and the value of salmon carcasses for creatures other than bears and maggots.
Some possible questions:

What species and sex of salmon is this?
What do you think killed the salmon? (This carcass was near the mouth of Eagle River in the intertidal zone).
Are the ravens both juveniles and adults?
The ravens show several types of behavior. It could be interesting to ask several questions about what they are doing and why. This could require research into the literature on their behavior.
What species of gulls are these and do they nest in the Juneau area.
The one gull appears to concentrate on the two most important parts of a salmon carcass for nutrition. What are they?
Three different eagles fed on the carcass. Based on their plumage what age do you think they are?
Why did an obvious juvenile eagle displace the adult eagle?
And many more………………………
The video could be paused at specific spots and then a question could be asked.
