Yesterday evening, I had an almost full hummingbird feeder; [View all]
about 6/8 full after several days of very hot weather in the 90s, that derecho storm that went through fast and did not do much damage in my area, and a few pop-up rain showers; it holds about 4 cups - this morning I look and see a feeder that is only perhaps 3/8 full - I only see perhaps 1 - 2 hummers sipping perhaps twice daily--a couple sips and off they go; where did all the juice go overnight? I investigated and noted no obvious leaks-- it's a glass feeder hung upside down on a shepard's hook with a bottom-filling plastic six flower screw-on plastic lid for filling with a stand so hummers can alight. Evaporation from those 6 tiny sipper holes in breezy conditions? Expansion/contraction of filling lid?Changes in barometric pressure push it out of those little holes overnight though dew point is higher yet without outside dried up evidence? Before I wash and change out the DIY nectar today, I have to say I'm stumped as to where all that nectar went in a single night.
