  There are flying rates for owls, like the barn owl is 80 km/h. Flying from NA to Europe wouldn’t even take more than 100 hours (60 from Boston to Lisbon), so with that it would mean the bird would be spending 3kW of energy, which is just nonsensical.

  All birds have a kJ/d amount, and even with a huge multiplier you wouldn’t come anywhere near the amount in the meme.

  There’s a few hundred that migrate from eastern NA to Europe and Africa, but no owls. Owls don’t really migrate at all. I did all the calculations in a different comment in this thread and the shitpost is so off it’s incredibly easy to disprove.

  It is falsifiable, just from a basic bird standpoint. Energy usage and flight speed is listed on allaboutbirds.org and you can calculate the rest just from knowing how birds work (for one, owls don’t really migrate at all, though there are of course exceptions with everything in bird world).

  The barn owl (the most common owl on the planet) weighs max 700g (listed on Table 1 here birdsoftheworld.org/bow/species/…/appearance#meas but you need a subscription). So like 1.5 lbs.

  Birds don’t really migrate east/west, and owls hardly migrate at all, and only a few species, not really barn owls. I’m not sure if there is an owl that migrates like that but even if it was true, tiny ruby throated hummingbirds migrate nonstop across the gulf. Weight doesn’t really matter.

  Kilowatt is a rate of energy, not an amount. So let’s calculate that. And energy use in owls is documented on birds of the world as well. Flight speed is 80 km/h birdsoftheworld.org/bow/species/…/behavior#locom

  Energy use is 360.4 kJ/d, let’s triple that for continual flight across the ocean (idk I’m just making that up since this is all fake anyway), so 1081.2, we’ll round up to 1100.

  Estimates of daily food consumption rates are limited. One captive female consumed a mean of 60.5 g/d over one year, amounting to 10.1% of her mass daily; consumption varied from 46.4 g/d in the warmest periods to 74.0 g/d in the coldest times (147). Two American Barn Owl consumed a mean of 74.1 g/d over a 10 d trial in August; it was estimated that energy use was 360.4 kJ/d (148). Other measures of daily food intake for wild American Barn Owl estimated from pellet contents range from 110 g/d in summer in Colorado (113) to a mean of 150 g/d over 1 yr in California (149). The mean gross energy intake for 4 (1 female, 3 males) sedentary American Barn Owl was 68.9 kcal/d; mean existence energy was 54.6 kcal/d, resulting in 79.3% efficiency in food utilization (150).

  I just measured across from Massachusetts to Portugal, around 3000 mi or 4800 km. About 60 hours, so 1100 kJ/24h / 24/h x 60 h = 2750kJ = 657265.774 Calorie.

  So yeah, very fake.

  Really weird reading an article that interviews someone you’ve worked for (who is a billionaire themselves).

  as an instance admin I will let you know that lemmy (the software) runs very very poorly.
