JIRINEC: Our study comes out on the same day as the conclusion of the U.N. Intact natural systems provide more economic benefits to humanity than the entirety of the world's GDP, so they matter to you whether or not you know it.Д¬HANG: Vitek Jirinec of Louisiana State says the timing of his paper's publication could not be more fitting. WEEKS: All around the world, people depend on natural systems. Weeks says these sorts of changes should concern all of us. DonвЂ™t worry about getting it perfect first time, it may take a few goes make the legs a little longer, the eye a little bigger or the chest more curved.

KELLY: The two studies reinforce the idea that birds all over the planet, migratory or not, may be changing shape due to a warming climate. But with a few simple shapes and lines, taken one step at a time, youвЂ™ll soon find that sketching a bird isnвЂ™t as impossible as you first thought. Nearly all of them were shrinking decade by decade. Now, here's an example that might be a little easier to relate to.Д«RIAN WEEKS: You could imagine lots of little ice cubes in a glass of water, as opposed to one big ice cube, and the little ice cubes melt faster because smaller things have larger surface area-to-volume ratios, so they exchange heat more quickly.Д¬HANG: Brian Weeks of the University of Michigan didn't work on this particular study, but he did study the size of more than 50 species of migratory birds in North America a few years back. It has more surface area in relation to its volume. And a smaller bird would shed heat more efficiently. Over the 40-year study period, the rainforest has gotten warmer. PHILIP STOUFFER: The thing that is the most striking about this to me is that this is in the middle of the most intact tropical rainforest in the world.Д¬HANG: Now, if you're wondering why that is, well, the short answer may be climate change. Philip Stouffer was Jirinec's advisor at Louisiana State. He and his colleagues have now found that over the past four decades, 77 different species of Amazonian birds have been getting slightly smaller on average. That is Vitek Jirinec of Louisiana State University. First draw a long triangle with a straight line in. Draw a circle with small circles inside for eyes and nose. You can refer to the simple step-by-step drawing guide below. Please see the drawing tutorial in the video below.

VITEK JIRINEC: But then we found that size is not only shrinking for those sensitive species. How to draw a bird easy for beginners and everyone. Not only were the birds declining in number, but their bodies were shrinking in size. In recent years, scientists found something strange was happening among sensitive bird species in the Brazilian Amazon.
