Cloudy nectar indicates bacteria and black
residue indicates mold. In either case
the feeder should be thoroughly cleaned as contaminated nectar can be harmful
to hummingbirds. It is advisable to hang
feeders in different locations because hummingbirds are extremely territorial and will chase each
other away from feeders. Domestic cats are
responsible for a lot of hummingbird deaths, so be mindful when choosing
locations. There are numerous styles of
hummingbird feeders but I prefer the ones with a perch. This way they can rest a bit, while slurping up the juice. Nectar
only makes up a portion of the hummingbirds diet. They need a steady supply of protein and
feast heavily on insects. They also use
spider webs in nest construction so avoid insecticides if possible.
Lastly, leave your feeders out until there
have been no hummer sightings for at least 2 weeks. Hummingbirds have an internal clock that
tells them when to head for warmer territory.
They will leave whether or not hummingbird feeders are still out. As the daylight hours lessen the birds will
begin to depart. The Anna’s hummingbird
is the exception. These hummingbirds are
known to remain year round. I have never
had Anna’s hummingbirds in my yard but will look into getting a heated feeder
if that should change. Happy hummingbird
happenings to all! Sources: Cornell Lab
