After hours of waiting and just missing out on taking photos
I managed to sneak up on this little fella on the feeder.
I was indoors at the time so the photos are a bit dark.
They are about 3 1/2 inches in size.
Some of them aren't much bigger than the local dragonflies.
With the help of Mr Google I've discovered that she is a female Ruby-Crested Hummingbird.
We also had a Black-Chinned Hummingbird but that one flew away before I had chance to get the camera. At one point we had two birds on the feeder at the same time.
