[cobirds] Purple Finch in Boulder

[Joyce Takamine]

Had a male and two female Purple Finch at my feeders.
First saw the male which did not look right for a Cassin’s
Since it did not have the peak on the head.  Then I noticed
two females.  They had very pronounced brown and white
Head pattern and wide stripes on the chest.

[cobirds] Boulder Evening Grosbeak

[Joyce Takamine]

Friday afternoon had an immature Evening Grosbeak at my feeders.
Have not seen any mention of them on e-bird in Colorado recently.
I noticed white in the wings on a stocky bird.  Was able to get my bins
on the bird and saw the yellow on the breast and large bill.

Re: [cobirds] Joe Roller sad news

[Joyce Takamine]

Joe was of tremendous help to me when I was doing the RBA.  When I needed
Someone to sub for me Joe would find people to help and he ad others took 
over when I retired.  Joe was the one who kept the RBA running for as long 
as it did.

[cobirds] Gyr Larimer 11/16

[Joyce Takamine]

This morning around 9:15 my sister Connie and I observed the Gyrfalcon
on one of the power pole on Trilby by the dump.  It stayed long enough for
us to get a good scope view to verify that it was not a Prairie Falcon.  We
had tried earlier around 8:30 but did not see it.

[cobirds] Miyake jima

[Joyce Takamine]

We are on the ferry heading back to Tokyo at a snails pace because of
Trump. So we do not know
When we will be able to dock.

We were on the island from about 5:30 to 13;30..  it took about an hour for
Phil and Jun to get the cars. We basically birded a nature center and got
most of the birds there.  Drove to a coastal spot for grasshopper warbler
and wood pigeon and tried to do pelagic birding but it was too windy so we
went back to the nature center and got a couple of birds that we missed
earlier.   Tried to do some pelagic from the ferry  but did not see much
 variety.

   2 males and saw at least one for a few days.  But in the last few days
   the tanager gang has grown.  Sometimes I can count about 10 birds
   at the feeders and in the nearby trees and bushes.  There are at least
   2 females but mostly males.  They are eating the suet blocks.  Has
   anyone else had such an invasion.  It is not unusual to see multiple
  tanagers are the feeder area.  They do not seem to like to share the
  suet block while they are eating.  There is at least one male that has
  a gorgeous bright red hood and he seems to be dominate.

[cobirds] Pink-footed Goose on New Years Day

[Joyce Takamine]

Maggie Boswell, my sister Connie and I decided to try for the Pink-footed
Goose.
We arrived around 8:30 and started scanning.  We found the Long-tailed Duck
several times but did not see the goose before the Bald Eagle scattered the
mass of
geese.  We continued scanning and more and more geese were arriving.  We
decided
to take a break to warm up.  When we returned we continued scanning from
the north end.
Soon Connie spotted the goose who was on the shore just feet from us.  We
saw the Pink-foot around 10:30.

[cobirds] retire from RBA

[Joyce Takamine]

CoBirders,

I want to let you know that I intend to retire from compiling the RBA on 1
Jan 2019.
I have been compiling the RBA for 14 years and think that it is time for
some new blood
or possibly some new means of broadcasting the information.

A lot has changed since I first started.  For one we no longer have the
phone line which
is sort of how it started.  News come from many sources now:  CoBirds,
WSBN, e-Bird,
and Facebook.  When we have a “hot” bird or birds it takes a LOT of time to
compile the
reports.

Good Birding,
Joyce Takamine
Boulder

Someone please tell Carol that her recent e-Bird reports are
in Spanish since they are from Columbia.  With so many
reports, I do not have time to look up every thing by its
Latin name.

Good Birding,
