(CNN) - Five thousand blackbirds in Arkansas. One hundred pelicans near Jacksonville, North Carolina. Three hundred doves in Italy. Seventy bats in Tucson, Arizona. Thousands of fish in Australia, New Zealand, Vietnam, the Philippines, Brazil and the United States.

Google is now hosting a map of incidents of mass animal deaths around the world. Google Maps' distinctive blue balloons indicate where the deaths took place. Click on a balloon, and the map provides you with a link to a news report on the incident.

As of Friday afternoon, there were about 30 cases pinpointed on the search engine's mapping site, most of them in the U.S. and Europe.

Some might say it's getting spooky - and not just by conspiracy theorist standards - but experts tell CNN Radio that theories of UFOs and secret government weapons are, naturally, far-fetched.

In the case of the Arkansas blackbirds, wildlife buffs have said that a loud noise or other event may have precipitated the blunt-force trauma that killed the birds. Of all the notions about their deaths, Susie Kesielke, curator of birds at the Los Angeles Zoo, believes the theory that fireworks startled the birds is the most plausible.

"Blackbirds roost communally in the wintertime, and they sleep more soundly than most animals," Kesielke said, adding that the birds were shocked awake and extremely disoriented.

Jonathan Sleeman, director of the National Wildlife Health Center in Madison, Wisconsin, said his office has investigated 16 mass bird deaths in the past 20 years.

"This is a bit unusual but not unique," he explained. "Most of the cases involved pesticides or poison ingested by the birds, but trauma has also been found to be the cause of mass bird deaths."

Good to know experts aren't buying that Armageddon is upon us. Offering even more comfort is the blog Universe Today, which suggests that the deaths aren't so much strange as they are "a symptom of the digital age where news travels faster than you can say, 'The End is Nigh.' "

It cites a Time magazine article that details several strange mass animal deaths and wonders "if the internet age allows us to connect the dots where there are none to be connected."

As for connecting dots, the blog suggests that the map on Google could be laid on top of a "current global oil exploration map to test the hypothesis that the deaths could have been caused by ground-penetrating tomography."

In any case, it seems level heads are prevailing for now - at least until scads of humans succumb to spontaneous combustion.

"Until the sky turns red and there's a plague of locusts, this event is not that unusual," Sleeman said of the blackbirds.
