[cobirds] Barr Lake CBC results

[Colin Woolley]

On New Years Eve we conducted the 43rd consecutive CBC at Barr Lake. We had 
nice calm weather, great visibility, and a great turnout with 39 
participants. We tallied 54,114 birds of 76 species, a bit above our 
average of ~70 species for the count circle. 

The relatively mild winter so far made for a lot of open water across Barr 
Lake and nearby reservoirs, leading to very high counts for waterfowl 
across the board. Cackling and Canada Geese always lead the way in this 
circle, this year coming in at 16,626 for those species combined. We had 
all time highs of Northern Shovelers, Northern Pintails, American Coots, 
and Western Grebes (4 this year, only 1 ever prior). Snow Geese and Ross's 
Geese were also quite high, though not all-time highs. The high visibility 
also probably contributed to our all-time high count of Bald Eagles, coming 
in at 153 this year (prior record of 120 in 2021).

Some songbird numbers were on the low end (but not all-time lows).We had 
unusually low counts of Black-capped Chickadees, American Tree Sparrows, 
Song Sparrows, Dark-eyed Juncos and American Robins. We missed out entirely 
on a few species that are less common but usually present each year such as 
Brown Creepers and Hairy Woodpeckers. 

Thanks to all the participants this year, it was our highest turnout over 
the last decade; great to see more and more folks in recent years!

[cobirds] Barr Lake CBC results

[Colin Woolley]

We held our Barr Lake CBC on Jan 2nd. It was a cold, foggy morning with 
limited visibility, but at least it wasn't snowing during the count! All 
things considered, we had a great day and were able to see plenty of birds 
despite the challenging weather (we couldn't even see Barr Lake for most of 
the count!). 

   - We had 23 participants divided among 9 groups.
   - We tallied 33,914 individual birds of 69 species. We average about 70 
   species so it was great to be right about at the average, despite the 
   weather conditions.
   - About 75% of those individuals were Cackling or Canada Geese, or 
   European Starlings, again pretty typical for this count circle.
   - We had one new species for the count circle, a Golden-crowned Sparrow!
   - We had an all-time high of 476 American Robin, more than the first 20 
   years of this count circle *combined *(1981-2000)*.*
   - Raptors were low across the board, particularly Great Horned Owls with 
   just one seen, tied for lowest (1991). This was likely driven by the low 
   visibility than anything else.
   - We saw 72 Bald Eagles, considering the limited visibility this was 
   higher than expected!

Thanks to all who participated in this count, we hope to see you again next 
year and we're always welcome to new participants as well!

[cobirds] Barr Lake CBC preliminary report

[Charles Hundertmark]

More than 40 hearty Colorado birders turned out yesterday for the Barr Lake
CBC. In temperatures soaring from 8 degrees up to 13, birders peered
through fog and occasional blowing snow to detect 66 species of birds. Few
rarities were found and poor visibility due to fog kept the number of
waterbirds in particular down. Highlights included Hooded Merganser, Great
Blue Heron, a good variety of raptors including Merlin, Long-eared Owl,
Brown Creeper, and Harris's Sparrow. Rough-legged Hawks were well
represented.

Thanks to RMBO for sponsoring the count and providing shelter from the
cold, and to all of the volunteers who thought that 8 degrees with driving
northerly winds would make a fun birding day.

[cobirds] Barr Lake CBC results

[Charles Hundertmark]

Forty volunteers turned out for a cold but clear Barr Lake Christmas Bird
Count January 4, 2013. The observer turnout, aided by one feeder counter,
was the highest ever for the count. The board, staff, and volunteers from
count sponsor Rocky Mountain Bird Observatory helped boost the number of
observers. Despite most open water being frozen, observers in nine parties
turned up 76 species, including two that were new for the count. An Eastern
Towhee and a Red Fox Sparrow (Barr Lake SP Visitor Center) were count
firsts. High counts included Snow Goose (40), Ross's Goose (8), Cackling
Goose (9505), Canada Goose (14,698), Red-tailed Hawk (123), Rock Pigeon
(793), Eurasian Collared-Dove (795), and White-breasted Nuthatch (10). A
 group including Chuck Aid and Bob Andrews the day following the count
added Snow Bunting (15) as a count week species.

Thanks to all who turned out to make this a successful count.

[cobirds] Barr Lake CBC Snowy Owl (Adams County)

[William H Kaempfer]

Chuck Hundertmark and Pete Plage found a Snowy Owl this afternoon (1/2/12) on 
the Barr Lake CBC.

Here are the directions.  Take Bromley Lane (152nd) east from I-76 and go two 
miles past Piccadilly To Harvest Rd.  Turn right and proceed for about 1.25+ 
miles to the south.  The owl is in a mostly snow covered field on the east side 
of Harvest just past address number 14141.

[cobirds] Barr Lake CBC, Jan. 3, 2011

[William H Kaempfer]

As opposed to most Colorado CBCs this year, the Barr Lake count witnessed a 
drop in number of species.  Only 63 species were recorded versus 71 in 2010, 69 
in 2009 and 76 in 2008.  A good part of the reason for that was that Barr Lake 
itself was almost completely frozen and that caused diving duck species numbers 
to, well, dive.

Two different Winter Wrens were observed (one near the Brighton Wastewater 
Treatment Plant might be chased by stopping at the park on the north side of CO 
7 at the Platte River bridge and walking 0.5 miles north to the second ditch 
coming from the plant) as well as a Northern Mockingbird and an American White 
Pelican.

Many thanks to the 21 observers
