So it's a type of thermobaric weapon. It's composed of magnesium hydride, which holds hydrogen more effectively than pressurized gas tanks, and it releases that hydrogen when detonated by a primer charge. It then ignites all that released hydrogen mixed with air to make a very impressive fireball.
A better name than "non-nuclear hydrogen bomb" exists, but would probably be longer and more specific. Hydride thermobaric bomb maybe.
It's the killdeer! We get returning birds across the road every year. Silly little running cotton balls with rock colored eggs in gravel nests, and they just had babies.
