We have again this year been thru 60 lbs of sugar in 65 days so far. We do not know how many birds but hundreds in three waves since June 15 in NM. Wash you feeders with every refill ( 120 ) so far on 32 oz feeders we use 3 very well with cold water and dry off before, do not spill and only use. 1 sugar to 4 parts water no need to boil, no color added, do otuse store bought humming bird solutions ever. Wehave been doing this for 8 years,they come back every year with more!
