What would cause hundreds of birds to die on a cruse ship recently.?

The use of pesticides to kill mosquitos.

"It is known the ship has 5G onboard, so this may be a factor." - well, there is your answer!   In my town a group of satanists were found to running a 5G abortion clinic.  It was set up so that the 5G antenna was hidden in the receptionists desk, and any woman who waited there for more than 3 minutes would spontaneously miscarry within a week.

"It is known the ship has 5G onboard...... ship is as yet unidentified."

If you don't know which ship it is how do you know 5G is used onboard? 

Birds were dying long before 5G came along. It's the lights and exhaustion, not the phones. Cruise ships are not the only things tired birds need to look out for in the seas. 

Interestingly you'd think that the shadow of person that you see is the one filming it, but if you look at .03 into the video that does not appear to be the case. 

There is nothing in that video to identify the boat, the location, or when it was recorded. Maybe it was a set up to promote some nutter's anti 5G propaganda.

In some places starlings are considered a pest and killed so perhaps a bunch of poisoned ones were gathered up and thrown on the decks.

There's a lot of dead starlings on the stairs but less on a lower deck that is quickly panned past. 

In any case there is nothing paranormal about bird corpses. 

Jesus, enough with the 5G myth already.  There is no illuminati, there are no chem-trails, no Santa, no Easter Bunny and no mind-control beams.  Those are all lies your parents told you and schoolyard mythology.

There are not many reasons left. 5G is possible.

It’s a bit of a stretch to blame 5G for this. There is no real mechanism for 5G to harm animals and birds, and how is it known this ship even had 5G? It doesn’t make a lot of sense. 

Have the birds been examined? That would be the best way to determine the real cause.  Groups of starlings have been mysteriously found dead before.

See:

If 5G caused bird deaths, here wouldn't be a bird left in Europe.  Someone is feeding you bird poop.

BS the ship has 5G.  I've been on cruise ships.  They have a limited satellite bandwidth to get Internet to the ship and then they use conventional WiFi.  There would be no value to even providing 5G especially considering the lack of hardware that supports 5G.

< Cruise ship is as yet unidentified > how convenient.  Yet someone could make a youtube video.
