Hi Dinusaur,
Did you happen to notice the bird flicking it's tail at all? What you've captured here is a Palm Warbler.
If you look at the base of the tail, called the 'undertail coverts', the overall colouring is yellow. The tail feathers themselves start off with a band of black colouring followed by a large area of white. This is diagnostic of Palm Warblers. No other Warbler has this pattern. Also note the yellow throat and the faint streaking on the breast. Although fairly difficult in this photo, you can see a slight bit of the brown colouring on the top of the bird's head. Most of these points are best viewed using your largest flickr page photo. Why I asked about the tail flicking was because that is also a good indicator that you have a 'Palm'. You have some wonderful photos in you collection by-the-way.
Happy Birding!
Walter
