Hi
I have a problem with a resident blackbird that has decided that the
mounting bracket for the sunshine sensor is quite handy for singing it's
song and claiming it's territory. Unfortunately I feel that after 6 months
of use the sensor may have become soiled and dirty. I am recording lower
levels of energy than May and this should not be the case. It is my
intention to clean this weekend. What should I use?

If there are any ornotholiogists among you I hope to hear from you on a
humane remedy for the blackbird. He's quite a chirpy fellow and I would miss
his song, but my weather equipment must come first

Thanks
Rob
