This bird bath has a drip fed by a rain barrel. It can be quite popular among migrants, if you are there at the right time to see them. On this particular day I photographed five warbler species in about 25 minutes. I’m using my Nikk0r 70-300mm AF-S VR II full out at 300mm. I could use another 200 mm, but couldn’t we all? Even heavily cropped it’s not too bad as long as you keep the image size down.
