Meadowlark includes the Lilian's race from Arizona and New Mexico and another 
race from northern Mexico. The proposal for this split was written by Johanna 
Beam, and is based mainly on a paper published last year in Ornithology which 
has Johanna as the lead author. The research for this paper was done when 
Johanna was an undergraduate student in Biology at CU in Boulder, and she is 
now a PhD student in Biology at Penn State University. I believe her interest 
in this subject started in 2015 when she found some Lilian's race Eastern 
Meadowlarks on the north side of McIntosh Lake in northwest Longmont, and 
submitted record 2015-089 to the CBRC. Johanna is a Colorado young woman that 
all Colorado birders should congratulate and take pride in.

CBRC records for Eastern Meadowlarks are at:  
https://cobrc.org/Reports/SpeciesDetail.aspx?id=463  There are 26 of them going 
back nearly 50 years, and at least 3 refer explicitly to the Lilian's race, 
which are 2005-22 from near the old Campo lek in Baca County, 2006-103 from the 
Colorado City cemetery and 2015-089 from McIntosh Lake in Longmont by Johanna 
Beam. Other records, especially 2003-33 and 2012-47 from south Baca County, may 
well also refer to the Lilian's race. This will be determined in the near 
future, so that the new Chihuahuan Meadowlark will be well documented to have 
occurred in Colorado. This highlights the importance of maintaining and 
expanding the CBRC database of rare birds in Colorado.

[cobirds] Meadowlark split

2022-08-03 Thread Peter Gent 
All,

The 63rd Supplement to the Check-list of North American birds from the
American Ornithological Society was published today in the journal
Ornithology.  As Brandon already notified everyone, included in the changes
was the split of Eastern Meadowlark into Eastern and Chihuahuan
Meadowlarks.  Chihuahuan Meadowlark includes the Lilian's race from Arizona
and New Mexico and another race from northern Mexico. The proposal for this
split was written by Johanna Beam, and is based mainly on a paper published
last year in Ornithology which has Johanna as the lead author. The research
for this paper was done when Johanna was an undergraduate student in
Biology at CU in Boulder, and she is now a PhD student in Biology at Penn
State University. I believe her interest in this subject started in 2015
when she found some Lilian's race Eastern Meadowlarks on the north side of
McIntosh Lake in northwest Longmont, and submitted record 2015-089 to the

[cobirds] Eastern Screech-Owl

2022-08-03 Thread Robert Righter 
Hi

While taking Lovey for her evening walk. at 08:20 pm heard an Eastern 
Screech-Owl calling for about 45 seconds, then the owl stopped. Waited for 
about 15 minutes, no more vocalization? 2300 block of South Milwaukee.

[cobirds] New Colorado species

2022-08-03 Thread Brandon 
The AOU just announced the split of Eastern Meadowlark into two species.
Colorado has had both, the regular Eastern Meadowlark and the new
Chihuahuan Meadowlark.  I don't know if any Colorado county has records of
both.  I have Chihuahuan in Pueblo and Baca Counties, and Eastern in
Fremont, Chaffee, and Huerfano Counties.  Since Eastern Meadowlark is on
the CBRC review list, so hopefully the CBRC will figure out how many
accepted records there are for each species.
