Dixon Reservoir and Maxwell Natural Areas
Leader: Ryan Twedt twedt@outlook.com. Dixon Reservoir and Maxwell Natural Areas are two adjacent and wonderful places to view migrating passerines in a variety of habitat. Dixon Reservoir is a well known migrant trap with annual banding stations operated by Bird Conservancy of the Rockies. The diversity of plant life and the insects attracted to them that surround the reservoir offer an abundance of food for migratory birds. A wide variety of warblers, flycatchers, grosbeaks, and buntings have been seen throughout the years during spring migrations, alongside numerous ducks, pelicans, and other water birds. Maxwell is a picturesque prairie/foothills area where towhees and bluebirds can be found with corvids playing in the breeze and raptors soaring high above. Start time and signup for this trip will be in the May newsletter.

125th Christmas Bird Count

Tufted Titmouse. Photo: Michele Black/Great Backyard Bird Count
The 125th Christmas Bird Count (CBC) will take place in count circles across the Americas and some Pacific islands from December 14 to January 5. As an alternative to bird hunts as a Christmas tradition, the first “bird census” was created in 1900. The CBC is the longest running citizen science survey in the world: tens of thousands of participants brave wintry weather and contribute to critical data on bird population trends spanning over a century.
Volunteer teams cover designated areas within a 15-mile diameter circle, counting every bird they see or hear all day (some counts may be shorter). All levels are welcome; beginners can be paired with more experienced birders. Volunteers who live within a count circle who just wish to record what comes to their backyard feeders also are welcome to participate; please contact your local CBC compiler for details. To center attention on this important effort, FCAS will not host any December field trips aside from the Bobcat Ridge Survey. For more information and to sign up, contact the following local CBC compiler for the area in which you are interested.
Fort Collins—Saturday, December 14
7:30am - 5:00pm
Compiler Thomas Hall, redbear44@msn.com. The count starts at about 7:30 a.m., though some groups may go out owling earlier. The count will conclude about 5 p.m. Team leaders compile information for an area and must have numbers by the end of the day for the compilation.
Nunn—Sunday, December 15
8:00am - 2:00pm
Compiler Robert Beauchamp, tyrannusb@gmail.com. The Nunn CBC covers the western portion of the Pawnee National Grasslands, just north of Nunn. Beginning in 1966, this count circle has been active for nearly 60 years. We'll meet at 8 a.m. for a day birding the short-grass prairie
Loveland—Wednesday, Jan. 1.
Compiler Denise Bretting, dbretting@swloveland.com or 970-402-1292. The Loveland CBC circle is a birdy combination of lower foothills, higher Great Plains, managed residential landscapes and gardens, a river corridor and plenty of lakes and reservoirs. Bird highlights are gulls, raptors, waterfowl, and sometimes a small mountain owl.
Rawhide Energy Station—Friday, January 3
Compiler Douglas Kibbe, dpkibbe@msn.com, or 303-910-9476. Please register early so the compiler can provide names to power plant personnel for permission to be on the property, particularly if you wish to survey the reservoir adjacent to the power station. Dress warmly. This is normally a half day outing.
Rocky Mountain National Park—Traditionally the first Saturday in January
Contact compiler Scott Rashid, pygmyowl@frii.com or 970-227-9425, for more information.

Sunday, January 14
Bobcat Ridge Survey
Leader: Denise Bretting
A hardy group of 6 participated in the January 2024 survey. Temperatures ranged from -4 to 1 degrees. But conditions were lovely for a winter hike, and we saw 13 species, including a passel of American Tree Sparrows!
Saturday, January 20
Rigden Reservoir
Leader: Robert Beauchamp
Ten brave souls weathered the chilly temps on Saturday, January 20th during the Rigden Reservoir Bird Walk. The reservoir was 100% frozen with only one Canada Goose on the ice, so the group birded the riparian area along the Cache la Poudre river, which was still flowing with open water. The group observed 19 species; highlights included Goldeneye and Hooded Mergansers. We were treated to an American Dipper and two Wilson Snipe, all foraging together in a shallow area. It was fun to watch the dipper plunge into the river looking for food. The big treat of the morning was a female Long-tailed Duck mixed in with the Goldeneye.

2023 Field Trip Reports
Highlights from 2023 Recent Bobcat Ridge Surveys
Even though our monthly bird surveys at Bobcat Ridge Natural Area were interrupted several times this year by muddy trail conditions and flooding issues, we still saw some interesting birds there in 2023.
Our species counts for the seven surveys conducted at Bobcat Ridge this year range from a low of 13 to a high of 44. The 2020 Cameron Peak Fire took its toll � about 85% of the area was burned to some degree � and it�s been interesting to see how the vegetation and bird species and populations have returned or changed.
Interesting species seen this year are American Three-toed Woodpecker (November), Merlin (also Nov.), seven species of sparrows in September, not including towhees or a single Song Sparrow. One or more Northern Harriers have been seen lately. Dozens of American Tree Sparrows were counted in December and January, and dozens of Lark Sparrows are typically seen in August. Sage Thrashers are regular migrants in the fall. We often find Northern Shrikes in the winter. Canyon Wrens are a little harder to find (not sure why), as well as nuthatches and chickadees.
The property was purchased by the City of Fort Collins in 2003. Even before the property was open to the public, regular bird surveys (now sponsored by both the City and Fort Collins Audubon Society) have been conducted there. Results are sent to the City and in more recent years, are also reported on eBird.
Our survey usually takes from three to four hours. Our �regular� route is about 4.5 miles long � we follow part of the Loop Trail, but have a short moderately steep section on the Power Line Trail. These surveys are open to those of any birding level � more eyes and ears are always welcome. And registration is not capped or limited to FCAS members, as we can spread out along the trail as we go. So long as the trails are open, we conduct these surveys in almost any weather conditions. Come join us some time!

2017 Field Trip Reports
Bobcat Ridge Monthly Survey
Date: December 10, 2017
Leader: Denise Bretting
Other attendees: 12
Highlights: The weather on this day was spectacular, and a good hike was enjoyed by all. But a long stretch of calm weather throughout the area may have kept winter migrants at bay, after most of the fall migrants had already flown south, so the bird diversity was unusually low. The usual host of corvids, chickadees, and nuthatches were as entertaining as always. A complete checklist of observations is available here: http://ebird.org/ebird/view/checklist/S41017453.
Loveland Area Lakes
Date: November 18, 2017
Leader: Michael Costello
Other attendees: 5
Highlights: This group visited many area lakes in a single day in pursuit of ducks, geese, gulls, and whatever else was present. Over the course of the day they saw all five of the geese species that are seen annually in Larimer County (Cackling, Canada, Greater White-fronted, Ross�s, and Snow) and a variety of duck species. They also found six(!) gull species at Horseshoe Reservoir, including a rare Glaucous-winged Gull, as indicated on this checklist of observations: http://ebird.org/ebird/view/checklist/S40593827.
Bobcat Ridge Monthly Survey
Date: November 12, 2017

Bobcat Ridge Monthly Survey
Date: October 8, 2017
Leader: Denise Bretting
Other attendees: 7

Eagle�s Nest Open Space
Date: September 16, 2017
Leader: John Shenot
Other attendees: 4
Highlights: Bad weather � rain, and lots of it � preceded this field trip. Fortunately, the rain stopped before the hike started, though it was unseasonably cold and menacing clouds filled the sky. Those who took the chance were treated to a Bald Eagle flying low overhead, a Common Nighthawk flying below the observers, a calling Golden Eagle, and another bout of pounding rain that nearly made the trail impassible. A complete checklist of observations is available here: http://ebird.org/ebird/view/checklist/S39221405.
Bobcat Ridge Monthly Survey
Date: September 10, 2017
Leader: Denise Bretting

Pawnee National Grasslands
Date: June 17, 2017
Leader: Bill Miller
Other attendees: 11
Highlights: This annual field trip is often a scorching hot affair, but this time it was actually pretty cool. So that would be nice, except it also turned out to be less �birdy� than previous trips to the Pawnee.

Leader: Denise Bretting
Other attendees: 21
Highlights: Ahhh, spring migration! After years of monthly surveys at this location, this survey group was the first ever to observe a Great Crested Flycatcher. They also observed a Lewis�s Woodpecker, a ridiculous number (20!) of Blue-gray Gnatcatchers, and more than 50 other species. A complete checklist of observations is available here: http://ebird.org/ebird/view/checklist/S36864183.

Colorado State Forestry Service Nursery
Date: May 6, 2017
Leader: John Shenot
Other attendees: 16
Highlights: What a difference a week makes! After our last snow-packed field trip, this one was warm and sunny. The group got great looks at three species of hawks (Red-tailed, Broad-winged, and Cooper�s), and heard Sora calling from a small marshy area. A complete checklist of observations is available here: http://ebird.org/ebird/view/checklist/S36589873.
Sunrise Ranch
Date: April 29, 2017
Leader: John Shenot
Other attendees: 1
Highlights: This trip did not go as planned. An unexpectedly heavy snowstorm arrived overnight and continued through the early part of the day. Most of the likely attendees had the good sense to stay home, and Michael Costello, who was to lead the trip, greeted just two people � then announced that he had severe back pain and couldn�t lead. The two attendees discussed going home, as the snow continued to fall, but decided to tough it out. John, who was familiar with the Ranch trails, filled in as guide. Eventually, the weather cleared up and the two intrepid birders got a rare treat, watching a Peregrine Falcon chase (unsuccessfully) a Willet over Green Ridge Glade Reservoir.

Bobcat Ridge Monthly Survey
Date: April 9, 2017
Leader: Denise Bretting
Other attendees: 20
Highlights: This month�s survey encountered the �usual suspects� for this location at this time of year, and not much else. One theory is that the abundant Western Meadowlarks (55 of them?!), scared away or ATE a bunch of rare species that would have been seen had the group come one day earlier. It�s just a theory.

Fossil Creek Reservoir Natural Area
Date: March 18, 2017
Leader: John Shenot
Other attendees: 10
Highlights: The weather was spectacular, the Western Meadowlarks were singing their hearts out, and the ducks � 11 species of ducks � were abundant. Great Blue Herons had settled into their rookery near the east blind. Spring was definitely in the air!

Bobcat Ridge Monthly Survey
Date: March 12, 2017
Leader: Denise Bretting
Other attendees: 14
Highlights: In Colorado, you often hear about bluebird skies. Well, I don�t think this is what the phrase means but it sure is cool: the group on this field trip observed about 200 Mountain Bluebirds, plus a couple of Western Bluebirds thrown in for good measure. High winds probably reduced the chances to see other birds, but 200 bluebirds? Seriously? That�s a good day!!!

Jackson Reservoir State Park
Date: February 25, 2017
Leader: Austin Hess
Other attendees: 3
Highlights: The weather was much more winter than hoped-for early spring, but as usual this hotspot did not disappoint. The group found around 30 Bald Eagles, a Cedar Waxwing pair with the male feeding the female, a Rough-legged Hawk, a nice duck diversity, around 30 Wild Turkeys (outside of the State Park), and 3 early migrant American White Pelicans. A complete checklist of observations inside the park is available here: http://ebird.org/ebird/view/checklist/S34788232.
Bobcat Ridge Monthly Survey
Date: February 12, 2017
Leader: Denise Bretting
Other attendees: 18
Highlights: As in January, the highlight of this month�s survey was once again an American Woodcock that continued to be seen throughout January and February. Well, that was the rarest bird anyway. High numbers of corvids also made the outing special: dozens of Steller�s Jays and even more Clark�s Nutcrackers, along with a scattering of Common Ravens, American Crows, Blue Jays, Black-billed Magpies, and Woodhouse�s Scrub-jays. Hitting double digits (10) on Cassin�s Finches rounded out the day. A complete checklist of observations is available here: http://ebird.org/ebird/view/checklist/S34325721.
Running Deer and Cottonwood Hollow Natural Areas
Date: January 28, 2017
Leader: John Shenot
Other attendees: 9
Highlights: Things were a little slower than usual at this natural area, due to less open water that is normal even for January. Still, the group got superb views of adult and juvenile Bald Eagles, and a Northern Shrike proved to be a �life bird� for some of the attendees. A complete checklist of observations is available here: http://ebird.org/ebird/view/checklist/S33986560.
Bobcat Ridge Monthly Survey
Date: January 8, 2017
Leader: Denise Bretting
Other attendees: 10
Highlights: Finding 29 species in one location can be a challenge in January, but despite the great variety of birds there can be no mistaking the highlight of this trip. The group was treated to views of an American Woodcock, for which there are very few historical records in Northern Colorado. This is the third January in a row that Woodcocks have been seen at Bobcat Ridge. Two individuals were observed. A complete checklist of observations is available here: http://ebird.org/ebird/view/checklist/S33548079.
