这两天打鸟发现蜂鸟的喂食器和普通鸟的不同，一个大玻璃罐子里装着红色的液体，谁
知道这是神马东东？蜂鸟只喝水吗难道？
附一张我其它帖子里的图，两种喂食器都有：普通鸟的和蜂鸟的。
又及，2013/01/23，今天在路上看到的喂食器，也应该是蜂鸟的，可惜空了。拍张照留
作纪念。

就是说用自来水兑白糖、再加红色食用染料？为毛他们非要喝红色的？

与自然食物源颜色相近吧，相当于“红烧”？

蜂鸟对红色特别喜欢喝敏感。

看维基的介绍
http://en.wikipedia.org/wiki/Hummingbird
我把有关喂食的部分拷贝过来
Feeders and artificial nectar
Hummingbirds will also take sugar-water from bird feeders. Such feeders
allow people to observe and enjoy hummingbirds up close while providing the
birds with a reliable source of energy, especially when flower blossoms are
less abundant.
White granulated sugar is the best sweetener to use in hummingbird feeders.
A ratio of 1 cup sugar to 4 cups water is a common recipe.[33] Boiling and
then cooling this mixture before use has been recommended to help deter the
growth of bacteria and yeasts. Powdered sugars contain corn starch as an
anti-caking agent; this additive can contribute to premature fermentation of
the solution. Brown, turbinado, and "raw" sugars contain iron, which can be
deadly to hummingbirds if consumed over long periods.[34] Honey is made by
bees from the nectar of flowers, but it is not good to use in feeders
because when it is diluted with water, microorganisms easily grow in it,
causing it to spoil rapidly.[35][36][37]
Red food dye is often added to homemade solutions. Commercial products sold
as "instant nectar" or "hummingbird food" may also contain preservatives and
/or artificial flavors as well as dyes. The long-term effects of these
additives on hummingbirds have not been studied, but studies on laboratory
animals indicate the potential to cause disease and premature mortality at
high consumption rates.[38] Although some commercial products contain small
amounts of nutritional additives, hummingbirds obtain all necessary
nutrients from the insects they eat. This renders the added nutrients
unnecessary.[24]
Other animals also visit hummingbird feeders. Bees, wasps, and ants are
attracted to the sugar-water and may crawl into the feeder, where they may
become trapped and drown. Orioles, woodpeckers, bananaquits, and other
larger animals are known to drink from hummingbird feeders, sometimes
tipping them and draining the liquid.[39] In the southwestern United States,
two species of nectar-drinking bats (Leptonycteris yerbabuenae and
Choeronycteris mexicana) visit hummingbird feeders to supplement their
natural diet of nectar and pollen from saguaro cacti and agaves.[40]
