What really killed the birds.

It's your basic localised supercharged low pressure bubbles, due to the magnetic fluctuations causing high energy particles to stream into minor holes in the lower magnetosphere.

The supercharged particles are heated from the energy and a lot become ionised and spread out to cause a relatively small sphere of low pressure and little oxygen, most the oxygen will be ionised and useless anyway.

Can only be sustained via a constant input of energy and so most are short-lived.

Nothing sinister, the low pressure knocks them out cold from lack of oxygen, some wake up as they leave the low pressure bubble, but they have already suffered severe internal damage from the lack of oxygen and the sudden low pressure that they cannot continue to fly.

What really killed the fish.

The same thing killed the fish as did the birds, instead of creating a low pressure zone and ionising the air, most of the supercharge that the water recieved went directly into the fish.

Because it was the easiest place for it to go to.

Path of least resistance and everything. The water that the fish had in them was mostly contained and the charge broke apart the molecules flash producing hydrogen and oxygen, which in effect drowned the fish, while giving them a slight electrocution.

The charge that didn't enter the fish would of been dissapated into heat.

Then as the source of the 'electricity' dissappeared (the crack closed) the hydrogen and oxygen combined back into water and the excess energy dissapated as heat.

There you go, The birds suffocated in air and the fish drowned in water.
