I had a bull climb a tree once!
Had a Angus bull (2000lbs+) that loved to scratch his belly and such on saplings @ the end of the pasture. Once he tackled a tree with a bit more spring in it than he expected.
I ck cows each AM & PM and good thing cause there he stood with his hind quarters about 1 foot off the ground. It seems when he tried to walk over the tree it fought back and bounced up....lifting him up! He gave me the most woe-begon look I've ever seen. you'd thought he was gonna start crying!
So it took a chain saw to cut him down....a bit of salve here and there on his belly scratches and a whole bucket of sweet feed to sooth his wounded ego! He NEVER tried that again!!!
