Tumblr (3.0; @art254)http://art254.tumblr.com/“Why is bird poop white? (Question submitted by Sarah Beth) Unlike mammals, birds don’t urinate. Their kidneys extract nitrogenous wastes from the bloodstream, but instead of excreting it as urea dissolved in urine as we do, they excrete it in the form of uric acid. Uric acid has a very low solubility in water, so it emerges as a white paste. This material, as well as the output of the intestines, emerges from the bird’s cloaca. The cloaca is a multi-purpose hole for birds: their wastes come out of it, they have sex by putting their cloacas together, and females lay eggs out of it.”<br/><br/> - <em><a href="http://www.smellypoop.com/facts_about_poop.php">SmellyPoop.com - Facts About Poop</a></em>http://art254.tumblr.com/post/596192056http://art254.tumblr.com/post/596192056Thu, 13 May 2010 17:52:49 -0400<img src="http://25.media.tumblr.com/tumblr_l2dn4pU8oZ1qab9mso1_250.jpg"/><br/><br/><p><a href="http://www.portlandmercury.com/portland/IssueArchives?issue=2443959">Portland Mercury | Issue Archives | Apr 15, 2010</a></p>http://art254.tumblr.com/post/596114420http://art254.tumblr.com/post/596114420Thu, 13 May 2010 17:17:13 -0400<img src="http://25.media.tumblr.com/tumblr_kzevf3Zwf91qab9mso1_500.jpg"/><br/><br/><p><a href="http://www.theonion.com/content/magazine/the_silent_killer">The Silent Killer | The Onion - America’s Finest News Source</a></p>http://art254.tumblr.com/post/453858909http://art254.tumblr.com/post/453858909Wed, 17 Mar 2010 01:33:01 -0400<img src="http://25.media.tumblr.com/tumblr_kz91dqIqW81qab9mso1_400.jpg"/><br/><br/><p><a href="http://sideshowpress.blogspot.com/">Sideshow Press</a></p>http://art254.tumblr.com/post/446569408http://art254.tumblr.com/post/446569408Sat, 13 Mar 2010 20:56:14 -0500<img src="http://25.media.tumblr.com/tumblr_kz34svugiQ1qab9mso1_500.jpg"/><br/><br/><p>outgoing Mar 10 07 (via <a href="http://flickr.com/photos/donovan_beeson">donovanbeeson</a>)</p>http://art254.tumblr.com/post/439623878http://art254.tumblr.com/post/439623878Wed, 10 Mar 2010 16:24:30 -0500<img src="http://25.media.tumblr.com/tumblr_kyxpnhgdcK1qab9mso1_500.jpg"/><br/><br/><p>via <a href="http://designarchives.aiga.org/assets/images/000/018/072/18072_or.jpg">designarchives.aiga.org</a></p>http://art254.tumblr.com/post/433287457http://art254.tumblr.com/post/433287457Sun, 07 Mar 2010 18:09:16 -0500<img src="http://25.media.tumblr.com/tumblr_kyxpftBmMu1qab9mso1_400.jpg"/><br/><br/><p>via <a href="http://designarchives.aiga.org/assets/images/000/014/821/14821_lg.jpg">designarchives.aiga.org</a></p>http://art254.tumblr.com/post/433278944http://art254.tumblr.com/post/433278944Sun, 07 Mar 2010 18:04:41 -0500<img src="http://25.media.tumblr.com/tumblr_kyxpcaufs61qab9mso1_500.jpg"/><br/><br/><p>via <a href="http://designarchives.aiga.org/assets/images/000/014/680/14680_lg.jpg">designarchives.aiga.org</a></p>http://art254.tumblr.com/post/433274750http://art254.tumblr.com/post/433274750Sun, 07 Mar 2010 18:02:34 -0500<img src="http://25.media.tumblr.com/tumblr_kyxp6s0Pfe1qab9mso1_500.jpg"/><br/><br/><p>via <a href="http://designarchives.aiga.org/assets/images/000/014/823/14823_lg.jpg">designarchives.aiga.org</a></p>http://art254.tumblr.com/post/433268640http://art254.tumblr.com/post/433268640Sun, 07 Mar 2010 17:59:16 -0500<img src="http://24.media.tumblr.com/tumblr_kyfh6ami6X1qab9mso1_500.jpg"/><br/><br/><p><a href="http://ffffound.com/image/c378f54637dbe065d9214623d3a330c3e35ff0a3">FFFFOUND!
