Subject: 100% survival rate Re: hummingbird mortality
A hummingbird bander friend of mine (Bruce Peterjohn) in
Maryland/Delaware says that this is a very poor year for western
wintering hummingbirds in his neck of the woods. This seems to be
true in the Charleston area as well. I wonder if all those fall
hurricanes and tropical storms had something to do with it?

At any rate - my mother in Charleston also had far fewer than normal
hummingbirds this winter. Instead of the usual 8-10 she only had
3, all Ruby-throated Hummingbirds. One adult and one immature male
and one that may be a female (lacks any gorget or flecking
whatsoever). Last year was the first year in over a decade that she
has not had a Selasphorous hummingbird.

Happily all three hummingbirds are still alive and feisty (as is her
male Painted Bunting). My mother kept four heated hummingbird feeders
and multiple oriole nectar feeders going throughout the freezing
weather. Since I recall Gary Phillips and others saying they had
observed wintering hummingbirds seeking "midnight snacks" my mother
keeps 2 heated feeders available all night just in case.

The four hummingbird feeders she kept out of the weather - hanging
under the eaves of the house front and back. All four feeders were
kept warm by clamp-on shop lights with heat bulbs in them. Rather
than light bulbs, pet stores sell ceramic heat bulbs that emit heat
but not light. This is good for keeping a hummingbird feeder warm
without causing light pollution that might disturb roosting birds,
etc. Sadly heat lamps don't work as well during high winds!

She kept the Oriole feeders thawed by warming the glass bottles before
filling with warm sugar water and swapping things every couple of
hours during the worst of the cold. She also had to swap jelly that
kept freezing, bring in the suet feeder at night, etc.

* Another thing that helped the hummingbirds survive: my mother has
Camellia and Sasanqua bushes planted on the south side of her house,
and they extend up under the eaves of the house. So between feeding
sessions, the hummingbirds were able to get out of the precipitation,
somewhat out of the wind, on the south facing side (sunny side) of the
house when the weather cleared but the cold persisted.

So between these measures and the slightly warmer temps compared to
NC, all the hummingbirds survived.
