On average, the decline in mass of spring migrants over the 46 year study was just 1.3%," says Dr Buskirk.Looks like academic standards are declining. This is well within error of measurement area. It's not only the social science faculties that are full of morons today. It is spreading. Idiocracy is approaching."For a 10g warbler that's a loss of just 130mg."
But some species are losing more weight.
For example, the rose-breasted grosbeak has declined in mass by about 4%, while the Kentucky warbler has dropped 3.3% in weight and the scarlet tanager 2.3%.
This has been a cold winter. Perhaps those hatched out this spring will grow larger and develope longer wing spans.
Or the smaller size of song birds could be caused by the condition of the world economy. Fewer people putting out wild bird food
Jail birds on the other hand seem to be getting much fatter.
My first question is who are we paying to study almost half a million birds?
Then why are people in the southern US so much fatter than people in the north?
Downsizing as the economy worsens isn’t unusual. Birds will just have to do their part!
Too funny. “Scientists” seeing things that they want to see.
I’m sure they’re right but i always thought warm= greater size due to among other things,more food.
Climate change ‘makes birds shrink’ in North America shortly after a previous climate change made them shrink from dinosaurs...
That's a premise easily disproven by McDonalds' rule. I live in a warm climate (southern CA) and when I'm eating McDonalds burgers in my parked car I'm besieged by flocks of pot-bellied sparrows and seagulls begging French fries and other greasy morsels. Some of those birds are getting hugh!
The fraud and dishonesty just keep on coming... (see words in caps below)
Headline:
“Climate change ‘MAKES birds shrink’ in North America”
In the article...
“Songbirds in the US are getting smaller, and climate change is SUSPECTED as the cause.”
And they have the audacity to call this crap science?!!
What I SUSPECT is that the people that did this so-called study that arrived at this “conclusion” are bird brains. And I’m more confident of my conclusion than of theirs.
Antropogenic Global Warming, a turdly serious problem, according to the infallible AlGore, history’s greatest scientist, by far surpassinmg Newton and Einstein, also, as I have irrefutabley detemined, causes flatulence and hemorroids. We all know that people from warm countries, like Mexico, indulge in HOT foods, which invariably cause flatulence (beans, as in “Blazing Saddles”) and hemoroids. Hence, as it warms, we will all begin eating hotter foods, thereby falling victims to those two horrible, odious ailments.
Would you like to see something else that shrinks over time?
