Re: [mou-net] yellow-rump at suet feeder--hennepin county
Thanks to Rick for pointing out the digestive tract length of Yellow-rumped Warblers! (Tree Swallows apparently also share this trait of having relatively long intestines.) Yellow-rumped Warblers have several other cold-weather digestive adaptations, including the ability to reflux vegetation back into their gizzards, thus effectively digesting it twice. I have posted examples of a few other adaptations on my blog entry for today along with a photo of our first banded Yellow-rumped Warbler of the day. http://dantallmansbirdblog.blogspot.com/ dan On Thu, Apr 21, 2011 at 9:39 PM, Rick Hoyme rho...@comcast.net wrote: The Yellow-Rumps have the longest digestive track of any of our warblers which is required in order to be able to digest seeds and extract energy from them.

Since most of the insectivores haven't arrived back yet, there is less competition for what meat is around. -Original Message- From: Minnesota Birds [mailto:MOU-NET@LISTS.UMN.EDU] On Behalf Of Holly Peirson Sent: Thursday, April 21, 2011 9:41 AM To: MOU-NET@LISTS.UMN.EDU Subject: Re: [mou-net] yellow-rump at suet feeder--hennepin county These little guys (and gals) are omnivores, and generalists.

Re: [mou-net] yellow-rump at suet feeder--hennepin county
Speaking of butter-butts, here's one I had in my backyard yesterday morning. Not too many opportunities to see them in the snow! http://www.pbase.com/gymell/image/134079914 I just noticed one on feedercam too. I have suet out but it's in upside down feeders. So maybe it was going after peanuts or seeds. These little guys (and gals) are omnivores, and generalists. That's why they are so common and can come earlier than many other migrants.
