I have a small nest in my garden bed tall grass in my front yard that looks just like this with 6 ggs. I am in Louisville Ky. I was cutting the grass back when I saw it. I stopped and tried to move some of the remaining grass back around it. I'm concerned because it's in direct sunlight for most of the day. Will the bird come back to sit on it???

stay with it and try to catch them when the light is strong enough to see by and you might just be rewarded by what can only be described as a bird vortex...when they finally go to roost they will swirl tighter and tighter around the chimney or other suitable spot and one by one drop out of this formation to make their final approach. Unfortunately, if you are in a more heavily urban area with too much light pollution, the street lights coming on right at dusk might make seeing activity above them tough, but keep trying. Its a marvelous thing to watch. The nightjars are much much larger and have a loud distinctive "BEER!" call, and can be heard cruising above parking lots long into the night. for a recording of chimney swift twittering and other id tips, copy paste this: http://www.mbr-pwrc.usgs.gov/id/framlst/i4230id.html

Hi PotatoJoe, I'm not sure where you're located, but you may want to check out tufted titmouse -- classic "peter" song. I've linked below for you. Have fun birding by ear. Cathy in SWPA Here is a link that might be useful: tufted titmouse info

Looks like an Orchard Oriole. Their nests are not as pendant as Baltimore Oriole.
