About a week ago at The Hague, many birds died spontaneously, falling dead in a park. You likely haven’t heard a lot about this because it seems keeping it quiet was the plan all along. However, when about 150 more suddenly died- bringing the death toll to 297- some started to take notice.

And if you are looking around that park you might have seen what is on the corner of the roof across the street from where they died: a new 5G mast, where they had done a test, in connection with the Dutch railway station, to see how large the range was and whether no harmful equipment [sic] would occur on and around the station.

And harm happened, indeed. Immediately afterward, birds fell dead from the trees. And the nearby ducks that were swimming seemed to react very oddly as well; they were simultaneously putting their heads underwater to escape the radiation while others flew away, landing on the street or in the canal.

Again, almost at the exact same time that those animals died, near the station, Holland Spoor was tested with a 5G transmitter mast.

The birds that fell massively dead would be the victims of an experiment, performed on those days in The Hague, where RF radiation was tested with a peak frequency of 7.40 GHz, which corresponds to a wavelength of 4.05 cm. This wavelength is of the same order of magnitude as the size of the starlings. This may be important because of possible resonance effects. The mast in question is about 400 meters from where the starlings have fallen dead. This information comes from one source and should still be confirmed, if possible.


  1. Is it true that hundreds of birds have died in this park?
  2. If it is true, has a cause been positively determined?

    putting their heads underwater, that's normal duck behaviour, they are feeding...

    Is there any confirmation that there were tests of 5G nearby? Or what frequency was tested (note that 7.4GHz is NOT a standard frequency in the proposed 5G standards in Europe or anywhere else).

    isn't the wavelength "being the size of birds" part absolute non-sense ?

    I'll note that such unexplained bird kills are not that unusual -- one reads about them several times a year in the US (though perhaps not as massive as this one). Fish kills are even more common. Commented Jan 7, 2019 at 12:48

    I recall the case of some sea birds who flew through the smoke stack effluent of an incinerator that the Feds were using to burn contraband marijuana. A college professor got wind of this and decided to investigate the effect of the smoke on the birds. After extensive research he determined that there was not a tern left unstoned.

Seems to be true about a large number of suddenly dead birds. There are some articles in Dutch media reporting this. However the cause has not been determined and there is no mention of 5G antennas in reports.

Here is the Google translation of the article under the last link:

For several days in a row, dead starlings fall from the sky in the Huijgenspark in The Hague. It is estimated that around 150 birds have already lost their lives. What is the cause of this is being investigated.

The Dutch Food and Consumer Product Safety Authority, the Dutch Wildlife Health Center and a Wageningen University laboratory are investigating the cause of death of the starlings. A veterinarian of bird care De Wulp performed a number of birds last week. She only found internal bleeding and no trace of poison.

Contaminated water

"Last year we had the same situation at the Haagse Hogeschool, where it was renovated at the time", says an employee of the Animal Ambulance. "Then dozens of dead jackdaws were found, which probably had been poisoned because they had been drinking contaminated water. What's the matter now is really speculation, hopefully we'll know more next week, because this is not normal." Last Friday, the first reports of dead starlings arrived at the Haagse Dierenambulance. On arrival at the scene of the disaster exactly thirty starlings were found. They had fallen dead from a tree. Yesterday there were even more than ninety starlings in the park.

Sick dogs

According to hikers who put their dog on the spot, their animals also became ill afterwards. Dogs had to vomit and had problems with the stool. That is why the police temporarily blocked the site

    That's a lot of coverage if "keeping it quiet was the plan all along". ;-)

    @DevSolar And note that the first link leads to De Telegraaf which is (one of) the largest daily newspapers in the country :)

    @CommonGuy Well De Telegraaf is also the most sensationalist. Also the other news outlets you linked to are not my first choices for reliable information. Note that the article from Hart van Nederland writes the birds had no internal bleeding at all and speculated about poisoning whereas rtlnieuws seems to exclude poisoning while saying internal bleeding was found.

  • @11684 Do you want to say they all invented the story?

  • No but they might exaggerate and/or mix up the details (which they did).

  1. Is it true that hundreds of birds have died in this park?


  2. If it is true, has a cause been positively determined?

    There appears to still be no certainty about the cause.

Both the Natural History Museum in Rotterdam and the Wageningen Bioveterinary Research Laboratory in Lelystad think they have solved the riddle of the 'massive starvation deaths', this autumn in the center of The Hague. However, they come to totally different conclusions. They ate poisonous yew, says the laboratory. No, says the museum: they flew themselves to pieces.

  • I'd trust the BRL over some museum :) And of course the one does not exclude the other. A poisoned bird may inadvertently hit something when flying.
