The raptor rehab place where I volunteer is having a design contest for a volunteer polo shirt. Top portion is the lineart, bottom portion has the designs (on dark grey cause I have no clue what color the shirt will be). I'm partial to the right one because it displays Swainy field marks better, but if it is too expensive to print there is always the left one.

I went with a Swainson's Hawk (Buteo swainsoni) because:
1. They are common in town during the summer.
2. One of our most popular education birds is a Swainy
3. Golden Eagles and Red-tailed Hawks are cool, but I feel they are too commonly used
