But I have had occasion to see birders cheer odd things like actual life and death instances. I was co-leading a trip to Kearney, Nebraska to see a million snow geese and about 40,000 sandhill cranes pausing in their northward migration to their arctic breeding grounds. The highlights are going to the roost at dawn and at dusk to see the massive congregations of birds. When you aren't in the crane blinds you drive around to watch the birds forage for waste corn in the surrounding farm fields. Our group was watching a large flock when the birds suddenly spooked and took to the sky forming a huge gray crane tornado.
We soon saw what panicked the birds--an adult bald eagle was making tracks for the center of the tornado, its sites clearly set on one particular crane. The eagle made contact and clipped the crane, the bird flipped, the eagle rounded again and went to catch it. Meanwhile, everyone in my group was cheering. Half the group was cheering for the eagle and the other half were cheering for the crane to get away. As opposed to a football or a basketball game, they were literally cheering a life and death situation. One bird was trying to avoid starvation, the other bird was trying to avoid being eaten.
The eagle again dove for the crane and this time made actual contact. The crane was literally upside down and the eagle had at least one foot-full of talons lodged in the crane's belly. Bald eagles and sandhill cranes are roughly the same weight, averaging about ten pounds (give or take a pound or two). Even if this had been a twelve-pound eagle, it can only carry half its weight in flight. The captured crane flapped its wings and was able to dislodge itself from the eagle's grasp. The crane managed to right itself and fly away from the eagle.
Then it did something interesting—the crane made a beeline for our cheering group. The eagle turned and was in hot pursuit. The crane left the flock and flew right over our bus, meanwhile the eagle paused and went around our screaming group giving the crane some much needed distance to try and flee the eagle. In hindsight I wondered if the crane sensed the eagle would be wary of humans or was just so terrified of being eaten that it didn’t notice us? The surrounding din of thousands of cranes would have easily drowned out our voices. Eagles do not like to fly over anything dangerous so our group would have given it pause. But the eagle increased speed and continued after the crane. Both birds flew well out of sight and we never saw the finish but that adult eagle seemed determined and depending on how injured that crane was, it was very likely the eagle caught up to the exhausted crane and finished it off.
The adrenaline of the group wore down but we all noticed how strange it was to cheer and shout for that battle. What did say about each other and the side we chose?
I wondered if there were instances of birds cheering. I scoured my bird books and wondered if perhaps parent birds cheer on their kids when learning to fly?
No, not really, they either kind of sit aloof watching what happens. If anything, they taunt their young by not feeding them. And then perching some flight distance away starving the kids into flight.
Birds definitely scream and yell, usually when a predator is present and they are screaming and yelling: “Hey guys, there’s a thing right here that’s trying to hide and kill us!”
But I think the closest I came to finding a bird cheering is from a book called Mind of the Raven by Bernd Heinrich (which is a fantastic book).
