I've seen the bluebirds around the backyard this year, but this is the first time I've had the chance to photograph them. They are already starting to protect the bluebird house and all looks good for them moving in soon.

Here is the male having one of the mealworms from the feeder that is tucked inside that hollow log he is on. Having the feeder, which is just the bottom of a water bottle I cut out and screwed inside this log, allows the birds to come where I want them to be, while still looking like a natural scene.
Luck played a bit of a part in this image. This image was taken just a few moments before sunset on an overcast day, so light was getting pretty low. Because of that, even at my widest aperture and an ISO of 1600 I was only able to get a shutter speed of 1/160th. Getting a sharp image at 1/160th required a few things...first, I needed to be on a tripod, which I was, and secondly, the subject needed to sit perfectly still, which he did. That's where luck comes in. If this bird had moved in the slightest, the image would not have been sharp at 1/160th.
Often times, I read comments from people that think their lens or camera has an issue when they are shooting a longer lens, like this 150-600mm lens, because their image isn't as sharp as they would like. Most of the time the problem is more so with not using proper technique or paying attention to your camera settings. Like I mentioned above, at 1/160th of a second if this bird moved a tiny bit the image would not be sharp. That would have nothing to do with the lens or camera, but my shutter speed. I did not really want to raise my ISO any higher, because I wanted as clean an image as possible. I was aware of that when I was shooting and was banking on a little luck, which I got.
