ANOTHER UPDATE: Articles addresses superflights and causes for alterations in irruptive migration by birds including redpolls. 2/13
BIG UPDATE: Last week as mentioned below I asked people on the Audubon website if anyone else was seeing unusually large numbers of redpolls this year. There have been several responses along with some good advice and a wonderful rescue story. I added them below with the newer ones at the top. Polling Hollywood now for invasion of the redpolls movie. (I boldfaced the advice)
Original blog post:
This has become fun, if expensive. The birds, mostly common redpolls went through 40 pounds of
sunflower seeds in a week. That's
not an exaggeration. I opened one
a week ago Thursday and Thursday this week I had to buy another one and open it
immediately to keep up with them.
They pretty much empty five feeders in about 24 hours. That's three of them in the picture. Of the other two one is a duplicate of the one with the red top and the other holds more than twice what that red one holds.
At times if I could count them I bet there are more than 100 in the
yard.
This is more than I have ever seen. Over the years I've noticed there are
lots one year and hardly any the next.
For a while I thought they alternated years, but then went through three or four where there were very
few. Then this year they are
overwhelming.
I wondered if I am alone and feeding every redpoll in
Alaska, so I joined an Alaska Audubon bulletin board and asked if anyone was
experiencing the same thing. So
far I heard from people in Soldotna, Talkeetna, Homer and south Anchorage and all report unusually
large numbers of redpolls at feeders this year. No one has offered a good theory so far as to why.
I had one thought.
Perhaps the crappy summer we had stunted the growth of whatever they
usually eat in winter and so they are having trouble finding feed in the
wild. Another thought is the
crappy summer somehow allowed for a greater survival rate among them and as
more chicks survived, more are thus coming to the feeders. Hmm, just checking on something. Maybe it's global warming. Maybe they migrate and because of new
climate changes, they are staying all winter. Hang on, going to look that up.
A partial answer from the Cornell Lab of Ornithology: Common Redpolls are active foragers
that travel in busy flocks. Look for them feeding on catkins in birch trees or
visiting feeders in winter. These small finches of the Arctic tundra and boreal
forest migrate erratically, and they occasionally show up in large numbers as
far south as the central U.S. During such irruption years, redpolls often
congregate at bird feeders (particularly thistle or nyjer seed), allowing
delightfully close looks.
So, there's the answer. They migrate erratically. Sometimes they fly south, sometimes they don't. Now you have to wonder what triggers
either action, and it does indicate warming could have an effect. If it stays warmer here that may be what
keeps them It's good enough for
me, perhaps a combination of high survival rate and one of those years when
they erratically stay in the north.
Now I wonder if I could somehow shift the expense of these
sunflower seeds to someone who usually feeds them in the Lower 48. Probably
not, but donations are welcomed.

HERE ARE SOME OF THE AUDUBON RESPONSES:
QUICK UPDATE: Forty pound bags of black oil sunflower seeds are $4 cheaper at 3 Bears than they are at Walmart. Same Alaska brand. $33 and change.
I believe this is a Leucistic Redpoll. It was amongst the Common Redpolls that frequent my bird feeders on a daily basis. Here's the link.

The redpolls here in Nikiski seem to be increasing in numbers. Plus I'm still getting lots of chickadees (black capped and boreal) and nuthatches. Not as many Grosbeaks and gray jays, but I'm sure they will come back soon.

Thanks for continuing the conversation about the Red Polls, as I find this very interesting, especially since the Red Polls are across such a large territory - Anchorage to Talkeetna.
The Red Polls did come back to our south Anchorage feeders. They were gone for two days, then the snow hit and they are back at the feeders. However, there's not the same numbers as before when they were a mob.

I was gone for four days and of course the feeders were down to dust when I came back. Filled them this morning and the redpolls are back in big numbers again.

Back in the
70's and 80's we used to have flocks of redpolls at our bird feeders and I
literally haven't seen one since -- until this year. This past week we've had
lots of them. I don't have a clue … but I'm glad you're on it.

The best price on Black-oiled Sunflower
Seeds, currently, is @ 3 Bears. Also best to buy a large bag of mixed seed for
redpolls, as they will eat the millet. Avoid mixes with those large, striped
sunflower seeds- nobody eats those!

Two
days ago I went out onto the porch to put out yet more seed in the afternoon
& found a juvenile female redpoll laying on her back on the snow on top of
the flat fuel tank at the end of the porch,which serves as a feeder. I thought
she was dead but when I started to pick her up her legs kicked a little. I
gently picked her up and brought her into the cabin. She was clearly dazed,
though I had been inside for the prior 2 hours and had not heard a window hit.
Plus I have black screens on the outsides of all my windows so even if the
birds fly into a window, they see the screen and swing their feet up and hang
from it for a second before flying away.
I
gave the bird a few drops of water with an eyedropper, which she drank eagerly.
I set her in a small animal cage in a back room and left her quiet for an
hour.
The
sun was due to set in a 1/2 hour when I checked on her. She would need to
acclimate to the cold again to be set loose for the night, so I set the cage on
a table on the porch. I put a handful of seeds in the cage and stood watching.
She hopped around the cage and when she came upon the seed she began to eat. I
eased the lid off the cage and in a few moments she looked up and then flew out
and off to the forest.
Since
then she has been back with the flock, but whenever they all fly away, she
stays, calmly eating seed while I am nearby. I know it's her because a few
feathers on her head were bent out of shape by whatever she hit, and she has a
gold-colored poll instead of red, which I learned a few years ago, when I did
research on redpolls when writing a column about them for The Talkeetna Good
Times, denotes a juvenile bird. This girl seems to have lost some of her fear
of me.
There is a
squirrel which jumps onto the feeders and leaps at the birds and I wonder if it
leaped at the flock while they were feeding and this female flew into the wall
and knocked herself out. I'm just glad she re-cooperated and seems to see me as
a helper, perhaps.

Thanks for the comment and the story. I have those hawk
sillouettes on my windows and they still hit it. And I have seen
squirrels do exactly what you described.
-- Tim
I've tried everything too, and the mesh
screen on the outside of the window works best. Only thing is I can't take
photos through it. I've put up streamers, hawk silhouettes, paint daubs, &
plastic owls & the mesh finally stopped window fatalities. That's why I think this redpoll flew into the
wall -- especially since I did not hear a window hit. She still greets me on a
feeder each morning now and hangs around a little while after the others fly to
the trees. My pal.
Cheers,

Is
the feeding frenzy over for the Red Polls? We haven't seen any Red Polls since
Sunday here in south Anchorage. The birds had been emptying the feeders about
every two days. Yesterday there was only one or two birds at a time. I'm
wondering where they went and who still has Red Polls at their feeders?
-- South Anchorage 2/5
For
a few days our numbers were down, but they started going back up today.
-- Homer 2/5
They
are still showing up at my feeders in Nikiski.
-- Nikiski 2/5
We
have about 50-100 daily, not an unusual amount but not every year amount.

Last week, while driving north on Minnesota near
Tudor in Anchorage, a large
flock of redpolls flew over. While I know they are
more common in town this
year, this flock was unusually large.I am guessing
about 200 birds. So,
there may be more in town than one thinks.
-- Anchorage
We've had up to 65 or more Common Redpolls at
our feeder, whereas in previous years we've had only one or two. A
bonanza year for redpolls at feeders.
--- Homer
We just started with bird feeders
about 4 weeks ago. First some Arctic Blend and then a little thistle to
bring those dang Pine Siskins in (it didn't work). Started with two
feeders, one about 8 inches high and one about 16 inches high.

Yes-about 70 redpolls here in the Talkeetna
area. Usually I have around 25 at my feeders and they don't come in to the
feeders until mid Feb. This winter I started out with 8 redpolls coming in with
12 Pine Grosbeaks back in Nov. The flock slowly increased to its present size
by mid Jan. The PG flock numbers around 20 birds. Just had a Shrike here 2 days
ago and a Sharp-shinned Hawk does a fly-by every once in awhile.
Black-capped Chickadee flock is down about 1/2
this winter, numbering around 25 birds.
I put out mixed seed for the redpolls to slow
down their consumption of sunflower seeds. Happy little birds!
-- Talkeetna
Yes!
I'm in the south end of Anchorage. We started out with about 20 birds, now it's
a mob scene at the front and back yard feeders several times a day and ran
through two 10 lb bags quickly. My
husband couldn't find plain sunflower seeds at two stores in town and ended up
buying a mix of millet, cracked corn, peanuts and sunflower seeds. Corn and
millet are scattered everywhere. Don't understand why stores here carry mixes
like this. Is millet good for anything? Am I missing something? I've always
wondered.
-- Anchorage
A NOTE: If anyone else can't find sunflower seeds, while I hesitate to promote Walmart, they do carry 40-pound bags (and also smaller ones). They have a variety of other feeds as well and they at least sell the Alaska brand. Also note the message from Talkeetna above. Putting out mixed feed slows down the consumption of sunflower seeds.
It took just slightly over two weeks for the
birds (mostly Redpolls, but a few Nuthatches and BCCHs) to empty the feeders
the first time I filled them. It took about a week for the birds to empty
the feeders the second time I filled them. Then about four days...now
it's done to about two days.
-- Anchorage
The Blacked-capped Chickadees still are around a bit, but the
Nuthatches seem to have "been driven off" perhaps.
I won't complain
though...it's a wonderful Sunday morning sipping coffee and watching the
Redpolls mob the feeders.
I bet the word "Redpoll" is mentioned 25 times a day in my
house these days.
-- Anchorage
I have 100-200 in my yard feeders in Soldotna. This
is one of the higher years (I have had 300 at one time) and they just showed up
a week or two ago,
