Just so you know, those numbers are way off. If you think about it how would a hummingbird consume that amount of calories in half its bodyweight? See https://www.birdspot.co.uk/bird-brain/how-many-calories-do-hummingbirds-eat-in-a-day https://www.birdspot.co.uk/bird-brain/how-many-calories-do-h...
I mean, when extrapolated to human size it's still 125k calories a day, but 6600 for a bird of 3g is just not possible.
- vkou 5y agoThey are (deliberately?) juxtaposing calories (the scientific unit of energy) and kilo-calories (the nutritional unit of energy). Unfortunately, the latter are, confusingly, also called called 'calories', despite one nutritional 'calorie' being 1000x of a 'regular' calorie.
- adrian_b 5y agoYes, that must be the source of confusion. 6000 to 12000 calories, not kilocalories, per day, means 1.5 g to 3 g per day of sugar, which is plausible for a humming bird.
- FunnyLookinHat 5y agoI thought it was accurate - k-cal are usually represented as Calories (capital C) as opposed to the individual unit of measure: calories. See: https://en.wikipedia.org/wiki/Calorie https://en.wikipedia.org/wiki/Calorie
- chrisseaton 5y ago125k calories is about half a chocolate bar. It’s not a lot.

- alisonkisk 5y agoIt's 125k kcal.
- alisonkisk 5y agoOnly the "6,600 to 12,000 calories per day." is way off, because it's physics cal not nutritional (k)cal. And it's more like 100lb of hamburger for a human, not 300lb.
