Joules, keep them coming.
One thing I've found in about 5 years owning a DSLR is that a motionless person, particularly sitting, for me often a lawn chair, is not threatening to many birds and animals. Often I'll pack along a good book and plan to just sit and read with the camera handy. Many of my best shots have come in these circumstances. When I tramp through the bush it seems I'm more likely to not see anything because they are far ahead moving away from me.
I try to observe from afar and if I see subjects then I quietly move into the area and set up to read (not in winter though).
Once while sitting right beside a very small creek that cut though a slough a baby muskrat came out of the water no more than 8 feet from me and proceeded to eat bulrush leaves for a number of minutes. Luckily, the 300 lens has pretty close focus. I couldn't stop pinching myself for days.

Not a bird but I'm posting it anyway.
