There are two different color variations of white-throated sparrow. There is the white crowned, an example of which is the first picture, and the tan-crowned, pictured above. The males of both varieties prefer white-crowned females, however the females all prefer the tan-crowned males. It appears that the white crowned birds are more aggressive then the tan crowned. So the guys are looking for an aggressive women while the females are looking for a laid back dude. You can see in the picture above that white-crowned sparrows eat a variety of fruits and berries. They also eat a lot of the seeds from different grasses as well as insects that they find while foraging on the ground.
