Something that you start being able to witness and capture is some really cool behavior when you spend a long time with a bird. This Kentucky Warbler is currently working hard to feed its young by gathering up whatever it can find, in this case a beak full of caterpillars. It landed on this perch for about 3 seconds and then took off right towards its nest only to return moments later with an empty beak and searching for more food. If I had only spent a few mintues with this bird I would have never seen this behavior but sitting there on the ground for 3 hours and you get to see some cool stuff.
