This is my favorite. I like the way the bird is abstract - the ones that use a "cartoonish" bird seem too much like twitter's icon and while they are playful they lack the sophistication I am looking for. I also like the colors, however blue and orange is over used today in web design and would prefer if we could find some thing a little different with the same feeling.
These are getting interesting. Take a look at the color scheme of our product at http://www.ibird.com - its the iPhone app in the banner floating above the ground - the background is green and the buttons are a different shade of green. So use of that color would be nice but its not mandatory.
I would also add the the reflection is clever but not needed because the effect is super difficult to reproduce on multiple surfaces. I could see it for a web site but I would like to see one without it.
I'm trying to imagine the logo on the home page of our site ibird.com. While I love the green shades it doesnt work that great on the page. Is there another color combo that might work best on that page. I'm not opposed to having the logo appear in different colors for different occasions but I would like to know if there are colors that will work on that page.
I like the rounded letters. Without the radio waves its not as vibrant to me.
