I put up two Humming bird feeders and it didn't take long for the Humming birds to find them.  I placed one under the soffit of the back porch in view of Pat's desk in the rear bedroom.  She can see the bird feeder from her chair as she sits and works on her computer.  The other feeder is located under the soffet of the front porch where I often have my coffee in the mornings.  The photo is a view of one of the birds at the feeder on the front porch. These little guys are amazing.  One seems to have taken over the feeder and guards it constantly.  He (or she) will always be near by and will chase any other Humming bird away if one approaches.  I have had a couple incidents on the front porch when I thought they were going to hit me when one was chasing the other away. Try clicking on the photo - it will enlarge and you can see the Humming bird easier.
