Re: Hummingbird Feeder
Most hummingbird feeders today have perches but when feeding
them became really popular in the 1970's, it was thought
that they wouldn't use perches so it was many years before
perches were added. The correct nectar for sunbirds may not
be the same as for hummingbirds.
The only recommended nectar is white granulated sugar and
water, prepared by boiling in a 20-25% strength i.e. 4 cups
water to 1 cup sugar. Very clean techniques should be used
(immaculate feeders, replacing the nectar every few days to
prevent mould and extra nectar stored in the frig).
Commercial nectars are available but should not be used as
they contain food colouring and tartaric acid. Most feeders
are colourful enough to attract them and the food colouring
is thought to make them more aggressive and may be effecting
fertility. Honey should never be used as it can cause a
fungal infection of the tongue. The white sugar duplicates
natural flower nectar and people make a mistake using fruit
syrups etc. which is fructose, not glucose.
I have found that adult males seem to prefer feeders without
perches and my guess is this is due to their territorial and
aggressive nature and keeps them ready for "fight and
flight". Females and juveniles readily use feeders with
perches.
I am involved in an annual hummingbird study here so could
ramble on quite a bit.
