Thank you, that was an ear-opening video--I had no idea.

I do remember this Awl article from a while back:

Some men shoot tigers. Some men love bears. Walter Rothschild, 2nd Baron Rothschild, Major in the Yeomanry, Conservative MP for Aylesbury in Buckinghamshire, heir to one of the greatest banking fortunes in history, and collector of the largest zoological collection ever amassed in private hands, had a specific and incurable addiction to cassowaries. He bred them. He stuffed them. He gathered living representatives of every known species and sub-species at his parents’ manor house in Hertfordshire. Bewitched by their beautiful and highly variable neck wattles, he identified new species where there were none. He wrote a book, A Monograph of the Genus Casuarius, about them and made excuses for them, and he could never get enough.

IMO the Shoebill stork is the most dinosaury bird

Ratites (flightless birds) and Tinamous (Chicken-like bird from Americas) were the first to split off from the other birds so I suppose you could argue they'd be the most dinosaur-y evolutionarily. All birds are technically Dinosaurs as far as taxonomy is concerned.

Other, IMO more convincing, version of those sounds that sound like a gun fight: https://youtube.com/watch?v=QFgYT3HfgP8

I remember seeing this! Yes, it's amazing. I saw these in a Florida wildlife reserve but didn't hear the machine gun mating call.

That sound legit gives my body shivers.
