Rufous Hummingbird continues at feeder in front of Horticulture Building, Montgomery Pinetum, Greenwich. I first saw bird 8:30am. It feeds very briefly (30 seconds at most), then flies off. It returned every 10-15 minutes to repeat that behavior until I left 9:50am. Note: Hummer was not seen using the low feeder nearby in front of the Botanical Center Building. Allan Welby Ridgefield
