Russian scientists tracking migrating steppe eagles copped a hefty phone bill.

The scientists from R.R.R. Conservation Network attached SMS transmitters to 13 eagles to study their migration flight patterns. They aimed to better understand possible threats to the endangered Russian eagle population (the steppe eagle was listed as endangered by the International Union for Conservation of Nature in 2015).

As the birds migrated four times a day, the scientists received SMS messages with coordinates of the birds' location. They used satellite photos to see where the birds ended up, according to BBC News.

Whenever an SMS message was sent, the Russian phone company MegaFon billed the scientists.

What the scientists didn't count on was one of the tagged birds flying out of range from Kazakhstan to Iran, which ran up huge data roaming charges for the team.

An onslaught of text messages from the bird ended up costing 49 rubles each (approximately 77 cents) -- which was more than five times the expected price, and ended up exceeding the research project's budget, according to The New York Times on Saturday.

But all is not lost. R.R.R. Conservation Network started a crowdfunding campaign to cover the costs, and MegaFon offered a refund for some of the roaming charges and will give the team a special rate to help continue the research project.
