Harriman Lake Park, November 3 – with Chuck Aid

Female Bufflehead (c) Bill Schmoker

This morning’s walk was a bit abbreviated as cold rain mixed with a bit of sleet sent us scurrying back to the cars posthaste.  Prior to that though we were able to enjoy a productive couple of hours working on our duck identifications.  We did not work on geese or grebe IDs because we saw none.  However, the ten duck species we saw now were spectacular. Most of the males were in glorious breeding plumage, though a couple of Mallards and several Northern Shovelers were still a bit betwixt and between.  Duck highlights included great looks at American Wigeons, Green-winged Teal, and Hooded Mergansers.  And, as we continue to look for new arrivals of those ducks that bred up in northern Canada and will now spend the winter with us, it was gratifying to find a pair of Common Goldeneyes.

Prairie Falcon (c) Bill Schmoker

The main highlight of the day was a Prairie Falcon, which we saw almost immediately as we first got out of our cars.  It was perched initially on top of a light post along Kipling, and then flew rapidly over to the top of another light post along Quincy.  This is part of a common foraging strategy for wintering Prairie Falcons.  From the top of a pole, or cliff, they can effortlessly survey their surroundings, and then once they have sighted a potential prey item the can swoop down, flying low, fast, and quite powerfully towards their quarry.  This behavior, alone, can almost be diagnostic in identifying a Prairie Falcon. Fortunately, we were also able to ascertain that it was a large falcon with obvious pointed wings.  Then, once it was on its second perch, we could make out the characteristic malar stripe below its eye.  (You might want to check out the introductory pages of your field guide to familiarize yourself with where the malar region is in a bird’s topography.) We could also see the dark ear-patch, and the distinctive white patch between the dark malar stripe and dark ear patch.  Again, though, it was the behavior of the bird that offered the best initial clues as to what it was.

So, once again, Harriman delivered.  It’s an excellent place for beginning birders as the lake is small enough that it’s possible to make out many of the ducks just with binoculars.

Hudson Gardens, Oct 27 – with Chuck Aid

Gadwalls (c) Mick Thompson

It was another great morning at Hudson Gardens.  We spent a fair amount of time working on the finer details of identifying five duck species. On Gadwalls the male has the big black rump and has silver tertials (the flight feathers closest to the body), and the female though relatively drab has white secondaries that when the wing is folded against the body cause a white spot to appear on her side. 

American Wigeon female (c) Bill Schmoker
American Wigeon (c) Bill Schmoker

With American Wigeons both male and female have a light bluish-gray bill and warm, brownish flanks; the male has an obvious whitish forehead and a distinct dark green swoop through the eye area; the female has her mascara smudged around her eye. 

Mallard male (c) Bill Schmoker


Mallards we know pretty well, but don’t forget the male’s curly black tail and clean yellow bill; the female has an orange bill with the black blobby spot on top; both have white outer tail feathers.  We only got to review male Buffleheads, as we saw no females, but we noted how white they were overall, with their relatively large round heads. For Hooded Mergansers we only got to see two males, but they were beauties, and unmistakable.

Mallard female (c) Bill Schmoker






We had some great looks at a couple of Red-tails, and one flew just a few feet above us providing a nice close-up view of its underside.  The birds had some nice differences and similarities.  So, while one was more of our classic light morph western Red-tail, the other was a much lighter looking individual with almost no buffy coloration – just black streaking on white for the belly-band.


Bufflehead male (c) Bill Schmoker

We had some good migrant activity with tons of American Goldfinches all over the place, and then right when we were leaving a large flock of Cedar Waxwings moved through. Also, had a couple of Dark-eyed Juncos. 

Overall, we had numerous opportunities for really nailing down some of the finer points of bird identification, and we all came away gratified at how much smarter we had become in such a short while – deservedly self-congratulatory!

Hudson Gardens, September 29 – with Chuck Aid

American Wigeon (c) Bill Schmoker

Throughout the summer when looking at ducks, most of what we see in the Denver area are Mallards with occasionally a few of the three teal species, and perhaps a Wood Duck, Northern Pintail, Redhead, or Common Merganser.  It’s possible to see some other species, but they are pretty uncommon.  Then, as we progress through the fall the Blue-winged and Cinnamon Teal leave and migrate south.  However, starting in mid-September we gradually pick up about fourteen additional duck species that have bred farther to the north, and will then be in our area throughout the winter.  On Saturday we had Blue-winged Teal that will only be around for about two or three more weeks, and we also had two newly arrived migrants from the north, Gadwall and American Wigeon.

Dark-morph Red-tailed Hawk (c) Bill Schmoker

Other highlights included a couple of juvenile Black-crowned Night-Herons, a dark-morph Red-tailed Hawk, a single Ruby-crowned Kinglet, and a single Orange-crowned Warbler – both of the latter perhaps on their way to spend the winter in the Sierra Madre Occidental of Jalisco, Mexico.







Juvenile Cedar Waxwing (c) Bill Schmoker

Finally, the big score of the day was the huge number of Cedar Waxwings we encountered.  It’s possible to see these birds year-round, but their numbers seem to increase once we get past breeding season, and, in fact almost all the birds we saw were juveniles.  We had multiple flocks of 15-30 individuals, and at one time had close to 50 birds in one catalpa tree.  Outstanding!

Hudson delivers again!

Barr Lake State Park and Banding Station October 6th 2018 with David Chernack

This Clay-colored Sparrow was a great catch at the banding station. Getting to see an example of this species in the hand was an opportunity to observe its unique coloration and diminutive size. (c) David Chernack

     The greatest lesson of fall birding is to expect the unexpected. Yesterday’s visit to Barr Lake State Park and its banding station run by the Bird Conservancy of the Rockies is a prime example. While the weather at a glance looked like it would be poor for birding, a cold front sweeping in from the north on Friday brought with it a who’s who of fantastic migrating songbirds for our group to see on Saturday. Our lucky group of six birders were able to observe many of these birds up close and personal as they were banded and released at the station, making for an excellent morning of birding!

     Bird banding is one of the most effective tools ornithologists have at their disposal to study birds. The quintessential banding operation consists of mist nets — fine mesh nets nets that are often set up in prime foraging areas — which harmlessly catch birds as they traverse an area of habitat. Researchers then collect the birds in small cloth pouches and transport them to a table with supplies for physically banding the specimens. The species, age, weight, and sex of each bird is determined and recorded before a band — a small metal ring with identifying numbers and letters — is affixed to its leg. The banded birds are then released; if they are caught at another banding station at a later date, their band can then be used to identify where else they have been caught. The entire process is harmless to the birds, although there is typically a great amount of complaining from the birds while they are being handled!

This Plumbeous Vireo, though handsome, was not too happy about being caught at the banding station. He had words with us! (c) David Chernack

      For our group, the banding station meant easier than usual views of some of Colorado’s best autumn birds. Birding during fall migration presents some challenges: most birds are not singing or vocalizing, so identifying birds by song is usually not an option; some birds are still calling, but differentiating calls between two warblers or two sparrows is a tough skill to learn. Additionally, many birds are molting into duller plumage for the winter season, so they may be hard to identify (which is especially the case with shorebirds) or even hard to locate. While we had some luck locating some warblers and sparrows as we walked from the Barr Lake nature center to the banding station, the up-close views we received while the birds were being banded were educational and incomparable.

     The species most frequently caught at the banding station that morning is also the most common warbler in Colorado: the Yellow-rumped Warbler. Both subspecies, Myrtle and Audubon’s, were present; this provided a fantastic opportunity to learn their differentiating traits at very close range. Also very common at the banding station were White-crowned Sparrows, some showing mature plumage (with the unmistakable white crown) and some showing hatch-year plumage (with a rufous crown, almost resembling an adult Chipping Sparrow or American Tree Sparrow). 

The Orange-crowned Warbler rarely shows and sometimes even lacks its namesake orange crown, as was the case with this individual (likely a female). They still possess a subtle beauty that is often overlooked. (c) David Chernack

     Two other species of warbler were also caught at the banding station: the Orange-crowned Warbler and the Wilson’s Warbler. Both species breed in the mountainous areas of Colorado, but are more commonly seen in greater Denver during their spring and fall migrations. The up-close looks at a half dozen Orange-crowned Warblers afforded us a rare look at their normally concealed orange “crown”; meanwhile, the Wilson’s Warbler that was banded at the station was still showing some very bright yellow coloration for so late in the season.

     For me, the best part of the morning was getting to see a good spread of sparrows up close. Identifying sparrows is difficult year-round, especially from a normal distance; seeing them from mere inches away was a real treat. Among the species observed in the hand were Lincoln’s, Chipping, Clay-colored, Song, and of course White-crowned Sparrows. Spotted Towhees, perhaps the most vocally displeased birds handled at the station that morning, were also wonderful to observe at such close range.


White-crowned Sparrows were the most common bird at the banding station; this picture shows the adult (front) and hatch-year (back) plumages. (c) David Chernack

   One especially special bird at the banding station was a Great Crested Flycatcher, a rarity for the greater Denver area. It presented a bit of an identification challenge as it bears an uncanny similarity to its western cousin the Brown-crested Flycatcher. Another bird that was tough to identify was a Plumbeous Vireo which showed up mid-morning. Plumbeous Vireos greatly resemble Blue-headed Vireos and Cassin’s Vireos, which breed to the east and west of the Plumbeous’ range respectively; the three vireos are so similar that until recently they were considered to be one species. 

     And while the banding station was a fantastic highlight of the morning, our group also made a point to survey Barr Lake itself for the plethora of migrating seabirds and shorebirds that stop to feed in Colorado as they travel south. The usual American White Pelicans, Double-crested Cormorants, Ring-billed Gulls, as well as plenty of ducks and other waterfowl were present on the lake surface. A Brown Creeper and Hairy Woodpecker rounded off our list for the day which reached 47 species.

Chatfield SP–Audubon Center: Sept 1 with Chuck Aid

Wilson’s Warbler (c) Bill Schmoker

Fourteen of us had a rather slow morning at Chatfield.  There were periods of almost total silence with regard to the avian community. However, we persisted, and managed to get a reasonable number of species even though the total number of individuals was quite low.

So, what did we not see?  We whiffed on Canada Geese, grebes, doves/pigeons, shorebirds (except for one Killdeer), gulls, herons, owls, woodpeckers (except for one Downy), vireos, and blackbirds/meadowlarks/orioles.

Western Kingbird (c) Bill Schmoker


What we did manage to see included three species of flycatchers: Western Wood-Pewee, Say’s Phoebe, and Western Kingbird.  We also had a few Gray Catbirds, Cedar Waxwings, and Lesser Goldfinches.  And, we had great looks at a couple of Yellow Warblers, a single Wilson’s Warbler, and a couple of Western Tanagers.  Fall migration is really the only time of year that we get to see Wilson’s Warblers in the Denver area, as their spring migration route is farther west and they breed high in the mountains.


Osprey (c) Bill Schmoker

The real highlight of the day may have been the raptors we recorded, though most of them were at quite a distance from us.  An Osprey gave us a fleeting view as it flew up the river.  We got to see Golden Eagles, Swainson’s Hawks, and a single Red-tail soaring; and we had an American Kestrel perched on a pole.  A few of us had a closer look at the two Golden Eagles as we drove back to the Front Range Birding Company.  They were on the ground tearing apart what was presumably a prairie dog and surrounded by Black-billed Magpies.  One was obviously a juvenile with the beautiful white “windows” in the wings and the white tail feathers with a broad, black, terminal band.  The other, which the whole group of us had observed while perched on a power pole, was a probable adult with the upperwing coverts paler than the rest of the dark brown feathers and forming a tawny diagonal bar.  This can be seen both on perched birds and those in flight.

Hudson Gardens: Aug 25, with Chuck Aid

Wood Duck female (c) Bill Schmoker

Saturday was a wonderfully mild morning for August, and six of us had a great time strolling through the peaceful environs of Hudson Gardens and along the South Platte.  The male Mallards were all clearly still in eclipse plumage – that time of year when male plumage is very like female – and the only way to tell who were the boys, and who were the girls was to look at the bill color – males = yellow-green and females = orange with black splotchiness.  The only other ducks we saw were a family group of a female Wood Duck with four juveniles.  These youngsters had not quite attained adult size and their bills were slightly smaller than mom’s.

Before getting into the highlights of the morning, we need to discuss one of our montane habitats a little bit.  A “carr” is a wet woodland or shrub area, generally dominated by willows, alders, and birches, and is often in an intermediate successional stage as a beaver pond transitions ultimately to becoming a montane meadow.  Often that intermediate stage is characteristically a saturated area of willows.  These willow carrs occur in Colorado’s mountains from about 8000 feet up to timberline at about 11,500 feet.  Got the picture?  So, with regard to birds, these willow carrs are prime breeding habitat for Fox Sparrows, Song Sparrows, Lincoln’s Sparrows, White-crowned Sparrows, and Wilson’s Warblers.

Wilson’s Warbler (c) Bill Schmoker

The point of all this habitat stuff is that you don’t necessarily need to go up to the mountains in order to see these species – just come to Hudson Gardens during fall migration. And, one of our highlights on Saturday was a beautiful Wilson’s Warbler.  Each fall migration these guys move down out of the mountains and can commonly be seen for a few weeks in the Denver area.



Cedar Waxwing juvenile (c) Bill Schmoker

Another highlight of the morning was the large number of Cedar Waxwings.  Most of these birds were juveniles and we even got to see an adult feeding its fledgling.  We also got to watch a group of waxwings gleaning insects out of a large spider web.




Cooper’s Hawk (c) Rob Raker

The birds of the morning, however, were the Cooper’s Hawks.  We got to have great looks at four individuals and had the opportunity to really break down all the physical features to look for in discerning Cooper’s from its very similar congener the Sharp-shinned Hawk, as well as telling juvenile and first-year Cooper’s from adults.  It was quite the seminar!  I’m not going to reiterate all those features here, but I will tell you that over the past five years the grove of cottonwoods just downstream from Nixon’s Coffee House has been a pretty reliable place in which to locate Cooper’s Hawks and they have had nests in there at least three of those five years.

Fall migration is happening, so I hope you’re able to pick up on a few species that you haven’t seen all summer.

Good Birding!

Wildflowers and Birds atop Guanella Pass – Aug 4, 2018 w/ Chip Clouse & Kimberly Beck

Our group of 13 intrepid high-elevation birders and wildflower enthusiasts enjoyed the FRBC Birder’s Breakfast (featuring Birds ‘n’ Beans Organic, Shade-Grown, Smithsonian Migratory Bird Center-certified “Bird-Friendly” coffee – always for sale at FRBC!) before car-pooling up to join Kimberly Beck, our wildflower expert, atop Guanella Pass.  Guanella Pass is certainly popular with hikers on summer weekends as it is easily accessible from I-70 and Georgetown and from Hwy 285 and Grant.  It is the gateway to Mt Bierstadt and other above timberline hikes and the parking situation definitely showed it.  We were finally able to all get together under the tutelage of Kimberly and begin identifying alpine wildflowers and looking for birds.

Avian diversity is always a bit lower at altitude but we were excited to see a few more species than I anticipated. White-crowned Sparrows were our most common sighting but a few Wilson’s Warblers were also working the willows.  We had a few hummingbird flyovers (including one definite male Broad-tailed) and a Clark’s Nutcracker also flew by.  After just commenting about the usual lack of ducks on small alpine lakes, we were surprised to find 4 Mallards.  Even more surprising was their behavior!  These dabblers were diving!  I was beginning to think I was in upside down world but this is actually the second time I have seen dabblers diving this year.  Subsequent research revealed that, though rare, dabblers do occasionally dive for food.  Another nice surprise was a juvenile Spotted Sandpiper.

Wildflower numbers were a little off this year due to the dearth of winter snowfall (and snowmelt) and overall heat and dryness.  Nonetheless, Kimberly knew where to find a few and wanted us all to be able to describe what we saw before putting a name to them.  I, for one, really enjoyed her methods of asking you to observe first, compare to what else you have seen and place together in families before revealing the genus and the species (where possible.)  Kimberly is from Relational Rewilding Nature Guiding.

Several folks were heading off toward I-70 and Georgetown as we concluded up top but 7 of us stopped at the Three Mile Creek Trailhead on the way back toward Hwy 285 en route to FRBC.  The mixed coniferous/aspen habitat revealed 7 more species in our relatively short stop.

Steller’s Jay, Common Raven, Violet-green Swallow, Black-capped Chickadee, Mountain Chickadee, Red-breasted Nuthatch, Golden-crowned Kinglet

All in all, a good time was had by all as we continued to offer our annual high elevation wildflower walk (with some birding thrown in.)  Special thanks to Kimberly Beck for her expertise and refreshing enthusiasm.  The mission of Relational Rewilding Nature Guiding is to foster mutually enhancing relationships between people and nature that inspire healthy ecological actions as well as personal growth.  I only wish we had we had more time with her!

Hudson Gardens July 28th with David Chernack

Late July is an interesting time to go birding in Colorado. Many birds are finished breeding, so songs are few and far between; some have even begun to stage for migration, fattening up before an arduous trip south for the winter. However, the upshot to these phenomena is that baby birds being reared by mom and dad are in abundance, and birds to our north that have begun their migration are passing through in fair numbers through the Front Range. For our large gaggle of birders at Hudson Gardens this past Saturday, this translated into some wonderful birding with up-close looks at 32 species.

Our walk began with a bang, as we quickly caught sight of some flyovers from a Snowy Egret and Black-crowned Night Heron, both of which we’d observe foraging later in the morning. Shortly afterwards, a marvelous adult Cooper’s Hawk perched in a cottonwood by the South Platte river offered superb viewing through a scope. 

While there were not many birds foraging in the river — some Canada geese, Mallards, and Snowy Egrets were observed — there was plenty of action in the surrounding trees. Our group quickly tuned in to the constant sounds of juvenile Downy Woodpeckers and Northern Flickers, still calling heartily to their nearby parents. One special moment spent with the young birds was watching a juvenile Downy observe its mother feeding on a mullein stalk and then proceeding to feed on it itself.

Further along the river, we observed some Colorado summer mainstays, including Western Kingbird, Yellow Warbler, and Barn Swallow, along with some more unique breeders. Three Gray Catbirds skulked through some nearby shrubbery, alerting us to their presence with their namesake “meow” calls. Catbirds, close relatives of mockingbirds and thrashers, are one of the few bird species that can identify the eggs of the Brown-headed Cowbird — a nest parasite — and remove them. 

Things really picked up as we returned to the Gardens proper en route to the freshly-filled bird feeders: in a small stagnant pond near the weather, our group was treated to views as close as twenty feet of a Black-crowned Night Heron hunting for fish. These unique herons breed in rookeries in the Front Range, but occur across the northern hemisphere. At the feeders, hungry birds were everywhere: Rufous, Broad-tailed, and Black-chinned Hummingbirds fed on a lone hummingbird feeder; more Downy Woodpeckers and Northern Flickers feasted on sunflower seeds; White-breasted Nuthatches, Mourning Doves, and American Goldfinches made appearances as well. Our walk was finally capped off with the sighting of three Ospreys — mom, dad, and junior — soaring overhead. 

Check out all the species we saw on our unexpectedly splendid walk on eBird here! 

Meyer Ranch, July 7, with Chuck Aid

So, I start with a bit of a disclaimer.  On Friday, July 6, my wife and I picked up our new eight-week-old Golden Retriever puppy.  As a consequence, Saturday was possibly not my sharpest day in the field.  Fortunately, we were accompanied by Master Birder, Wendy Wibbens who was able to straighten out my numerous misidentifications.

Twisted Stalk

First of all, we did not see or hear any Red-winged Blackbirds, leading me to believe that the dry weather may be impacting the wetland area at Meyer Ranch, and that the Red-wings that were there a couple of weeks ago have left for wetter pastures.  Certainly, one of the impacts of the dryness that we noted was that the flowers on all the Twisted Stalk plants in what are generally moist drainages had dried up and will not be producing their red fruit this year.

Cliff Swallow (c) Bill Schmoker

So now on to the birds that we did see.  Yes, there were babies – fledgling Mallards with mom in the little creek by the parking area, and fledgling Common Grackles in the same area. Also, along the creek was a family of Song Sparrows.  Hordes of Cliff Swallows were nesting on the US 285 overpass, and actively feeding young at the nests.  Out on the trail through the mixed pine and aspen forest we saw a young male Hairy Woodpecker whose tail feathers were still not fully grown out, moving along with an adult female – presumably his mom.  Perhaps the best baby sighting was of a nest full of Chipping Sparrow nestlings in a little lodgepole pine almost at eye-level.

Song Sparrow (c) Bill Schmoker

One of the main reasons we like to go to Meyer Ranch is that it can be a great place for Savannah Sparrows which prefer to breed in damp meadows, and at Meyer Ranch there usually appears to be a fair amount of sub-irrigating of the soil going on.  Perhaps, not so much this year, for we only managed to see a couple of birds.  So, in identifying Savannah Sparrows it’s handy to be able to start with Song Sparrows first, which are long-tailed, have a coarsely-streaked breast with a central breast spot, have some rufous in the wings, and have broad brown lateral throat stripes. 

Savannah Sparrow (c) Bill Schmoker

The Savannah Sparrow also has a streaked breast with a central breast spot, but it seems cleaner and better defined, and overall lighter underneath.  Perhaps the best thing to notice is that the Savannah Sparrow has a much shorter tail. The yellow supraloral spot seen on the bird in this photo is not always obvious, and can be difficult to make out.

Good birding! Chuck

Hudson Gardens, June 30, with Chuck Aid

Black-crowned Night-Heron (c) Bill Schmoker

Well, it was another beautiful morning at Hudson Gardens!  What a great place to stroll around and look at birds!  Starting with the waterfowl, we had many Mallards – females with their attendant youngsters, and males in various stages of acquiring eclipse plumage. I know that all of you who have come on our Front Range Birding Company walks now know that eclipse plumage is when male ducks, towards the end of breeding season, molt from their brilliant breeding plumage to a dull, cryptic plumage.  Furthermore, I’m sure you recall that this all happens at the same time that the main flight feathers are molting, and that some ducks actually become flightless for a few weeks – a good plan if you are temporarily flightless, to be more cryptically colored.  With the next molt the brilliant male colors will return.  

Great Egret (c) Bill Schmoker

Getting good looks at three species of herons was a plus: Great Blue Heron, Snowy Egret, and Black-crowned Night-Heron.  Just a reminder that Snowy Egrets have black legs with “golden slippers,” and they have a mostly black bill; Great Egrets, which we also get in Colorado, though not as commonly, have black legs and feet, and they have a yellow bill.  Black-crowned Night-Herons get their name because they forage predominantly at night (and, yes, they have a black crown), and we were fortunate to see a couple of adults.

Then, we had three species of woodpeckers, including a recently fledged Downy Woodpecker – kind of fuzzy looking, short tail not grown out completely yet, and acting a bit doofy.  And, we had a single adult male Hairy Woodpecker, the Downy’s larger cousin.  About 97% of Hairy’s nest in the mountains, so seeing one in town during breeding season is a bit of an anomalie – not completely unexpected, but certainly unusual. We were fortunate to have both a Downy and the Hairy in the same binocular field of view, so it was handy to be able to compare these very similar looking species.

One funny occurrence of the morning was that as we were looking at a singing Northern Mockingbird (a song that had been confusing me for a few minutes), we also got to hear at the same moment the cat-like meow of the Gray Catbird.  Both of the species are in the family Mimidae, along with several Thrashers. These birds are well known for the diversity of their songs, their capacity for song mimicry, and the incredible duration of their songs – sometimes over ten minutes.

Perhaps the stars of the morning were the numerous foraging adult Cedar Waxwings that were incredibly cooperative, to the extent that while being photographed one individual flew within two feet of the photographer.  She didn’t have to work hard to get close to that bird!

‘Tis the season of baby birds, so in your backyards you should be seeing the adults feeding and tending to their young.  Also, the Rufous and Calliope Hummingbirds which have already finished breeding to the northwest of us, are back in the area as their first step towards their migration southward.

Good birding!
