Birders, after reading a post about fewer hummer visitors, I thought I would add two observations: 1- I have one pair (1M, 1F) visiting the feeder regularly. I assume they are the same pair but can't prove it. They come singly and chase off interlopers. 2- It seems to me that the 'nectar' is getting bacterial or fungal growth much more quickly than I have seen in previous years. I used to give it a weekly bath in bleach or vinegar, rinse very well, refill, and it would start to get cloudy after several days. Now it is cloudy in 24-48 hours every time, and it doesn't seem to matter what I do to sterilize the feeder. Any thoughts?
