The honey, when mixed with water will ferment, which will cause hummingbirds to develop candidiasis (Candida albicans), more commonly known as thrush.
Other Diseases
…such as aspergillosis, salmonellosis, and mycobacteriosis have been documented.[1]
Aspergillosis is a fungal infection caused by the Aspergillus fungus…Spores inhaled into the lungs and air sacs of birds eventually cause pneumonia and bronchitis. Sick birds experience labored breathing, weakness, and diarrhea, but will continue to take food at feeding stations until they die.
Salmonellosis is caused by bacteria from the genus Salmonella and often begins as an intestinal-tract infection. Symptoms such as diarrhea, ruffled feathers, and lethargy usually occur. Birds who are showing symptoms usually die in 1 to 3 days.
Avian Pox, a viral disease, has been reported to infect 60 species of wild birds. Symptoms of the disease are lesions that form on unfeathered parts of the body such as legs, feet, and eyelids; around the beak; and in the mouth. In some cases, death can occur when numerous sores around the eyes prevent the bird from locating food…
Mites: Some species of mites and lice subsist on bird feathers and skin while others suck blood. Large numbers of blood-sucking mites can cause anemia and death in young birds while a nest heavily infested with feather mites may cause the parents to abandon the eggs or young.[2]

11 Seeing then that all these things shall be dissolved, what manner of persons ought ye to be in all holy conversation and godliness,
12 Looking for and hasting unto the coming of the day of God, wherein the heavens being on fire shall be dissolved, and the elements shall melt with fervent heat?
13 Nevertheless we, according to his promise, look for new heavens and a new earth, wherein dwelleth righteousness.
Revelation 7:17For the Lamb which is in the midst of the throne shall feed them, and shall lead them unto living fountains of waters: and God shall wipe away all tears from their eyes. and Revelation 21:4 And God shall wipe away all tears from their eyes; and there shall be no more death, neither sorrow, nor crying, neither shall there be any more pain: for the former things are passed away.
