Nostalgia and Anticipation


Another young Red-tail Hawk along South Boulder Creek. My employer's office is being relocated next week. Some of the folks who work here have been in the same location for close to ten years. For me the workplace location change isn't dramatic, I have only been with the company for five years, and a building is just a building. Plus, the new location is a bit closer to home - which is nice. What will be a difference for me are the locations of my midday walks, which provide a lot of the content for this blog. I am looking forward to more frequent visits to a few sites in that area, but will miss all my access to the abundance of open space in Boulder County. My plan had been to hit up one of my favorites each day this week, but weather and work being what they are I have only gotten pictures from Monday so far.


I had to hit up South Boulder Creek Trail, it has been a great place to walk over the past couple of years. Just across from Baseline reservoir, and with open space on either side of the wooded creek - this little stretch is one of my favorites. I wondered if this young Red-tail was the same as the one I had seen a few weeks ago. I doubt that it is, the markings don't seem an exact match, but this bird was my companion for much of the walk. It leapfrogged on my way to the far end of my walk. I was rushing along, because I had glimpsed a potential Harlan's Red-tailed Hawk beyond some trees, and was hoping to get closer to its perch in the distance than I had for the shot I took on a previous visit.


The bird vanished from its perch by the time I arrived near South Boulder Road, but caught a thermal in the leaden, storm-rolling-in sky as I returned to the parking lot.


Where it was later joined by the young hawk I had seen previously, (and even later by another adult to make a total of three hawks circling high into the sky). I know the shots are distant, but the birds emphasize that while colored differently, their shapes are much the same.

I am anticipating a whole bunch of new birding spots to explore, but have another bird topic that is equally exciting...



Today I registered for the 2011 Colorado Field Ornithologists convention. This year the site is Grand Junction, a dramatically different landscape and set of birds than what we have here on the Front Range in Colorado. I submitted my field trip requests and wonder what cool places I will get to explore this year. If you are in Colorado, and a birder of any level consider checking it out. The artwork above is the logo for this year's convention, it was created by R. Christopher Vest, www.photo.net/photos/chrisvest. For now though, more cold temps and at least clearing skies. Should be mild for the weekend, which will hopefully present opportunities for some foothills snowshoeing/birding.

Piling on


At what point does seeing good birds become an embarrassment of riches? After my great Downy Woodpecker start to the morning I headed out in the mild overcast for my lunch, and spotted this juvenile Cooper's Hawk at the end of my walk. That is two for two on Friday afternoons - not a bad streak!


Once again the bird was at the end of my walk, just as I was approaching the parking lot - this time at the Bobolink Trailhead on the South Boulder Creek Trail. I am also seeing a pattern develop. The walk this afternoon was entirely devoid of any small birds. I may have heard a lone Junco, but if I did it wasn't sticking its head out much. I think those quiet bird days in the future are going to find me scanning a lot more carefully for Cooper's Hawks.

It wasn't just the Cooper's Hawk though.


Earlier I had spotted a Red-tailed Hawk across the large field to the east of the trail. Closer examination of the photo revealed what I believe is a Harlan's variety of Red-tail. It's always fun to find those.

So, I am still no further along at getting through a backlog of photos, but in my book that is a good problem to have. Mountains tomorrow, and who knows what before football on Sunday.


Have a good weekend everyone!

Morgan County Day Trip

On Saturday I decided to undertake a self-guided birding excursion. It was to be the better of the two weekend days, and I wanted a chance to really get out and enjoy the high plains environment, beyond the urban sprawl of the Front Range corridor. Flipping blindly through my Colorado atlas, and doing a bit of reading on the Colorado Field Ornithologists' birding website, I decided to head out to Morgan County for the day.
Morgan County is a 'smallish', rectangular county in Northeastern Colorado. It is the next step east from my large, neighboring counties of Weld and Adams. The county features a state park on a good sized reservoir, a well developed agricultural and commerce corridor bordering the South Platte River, and it is handily located along interstate I-76 - making getting there a snap.


My first stop, and main birding area, was Jackson Reservoir State Park. Having left my home at just after 7:00, I was pulled in and counting birds before 9:00. My first sighting in the park itself was a male Ring-necked Pheasant. A good sign of things to come, but on this outing the photography was taking a back seat. I was trying to lean a bit more on my ears and bins first, and get shots as an afterthought. It was a good decision, when I got back that evening I found that my sensor had somehow picked up a collection of dust to rival the area beneath my bed - yuck. Despite that there were a few pictures worth sharing, and species that didn't make the cut.
Above were a group of gulls taken from the pier on the west side of the lake. It was near an area of open water that had some great birds hanging out. Before getting to the gulls in the picture believe me when I say that my report of 48 Bald Eagles was conservative. I had to stop looking for species after I had arrived and just do a sweep of the area to count individuals before they moved around too much. Adding to the impression of the sight was the fact that only 10-15% of the lake was open, so the birds were gathered in a small area of the rather large lake.

Back to the picture above though. I caught the two gulls contesting a catch which was fun, but check out the darker guy on the right - a California Gull. I tallied the California, a good number of Herrings, and of course Ring-billeds at the park. Three gull species, not bad, I guess my gull watches are having some effect.

Gulls are still frustrating though, so lets pause to admire a posed Dark-eyed Junco. "Ah, that's better." The Juncos were part of a loose mixture in the trees as I cam back from the pier. I had American Robins, Mountain and Eastern Bluebirds all interacting with them. The Eastern Bluebirds were the first that I had seen in Colorado.
After checking some of the Russian-Olive groves in that area I met another birding couple who mentioned having had a group of 7 Long-eared owls fly into the trees near them back near the visitor center. I stopped by on my way out of the park. I never saw the owls, but enjoyed this odd moment of nature from the parking lot. Two tom Wild Turkeys were displaying and competing with one another, but were separated by a chain link fence. I have no idea how long the dominance display lasted, or if in a Turkey's mind such a thing can be decided when there is an incomprehensible barrier dividing rivals. It was good for a watch though, and more comical as there was a large opening in the fence just to the left, but these two were so hung up with one another that they may still be there now.


After a very enjoyable time at the park I headed off for my next target - a pair of adjacent parks in Fort Morgan along the South Platte, one of which was appropriately named Riverside Park. A pond there had the full compliment of exotic waterfowl, along with high numbers of both Canada and Cackling Geese. Riverside Park was a bit overdeveloped and crowded on a mild Saturday afternoon, so I headed for the more natural Canfield Park. I had to work for birds, as my walk out was pretty quiet, but eventually birds started appearing. The river itself was strangely dull. I saw 6 Mallards and 11 Killdeer on the banks or in the water, and that was about it. On my return trip I stayed more inland, and was rewarded with more cooperative subjects, like this American Goldfinch.


As I turned from the Goldfinch a Wilson's Snipe exploded from the bank of a fishing pond behind me. A few minutes later a fisherman on the far side flushed it again, and it landed briefly in the open to allow a single shot in the light.


As I walked along I added a pair of Downies and dozens more Red-winged Blackbirds, and got this shot of an Eastern Bluebird posing with the sun at its back.


It was now mid-afternoon, and I had one more area I just had to check out. One of the locations the CFO site listed was a winding county road that cut through the dunes in the southern portion of the county. I wanted this route as it was reported as a great site for raptors, and who doesn't like winding country roads through dunes?
On my way south I picked a road at random from my atlas, county road "Q", and drove east. It was while I was on this road, trying to reach my target while swinging past a SWA, that I witnessed a site that many are inspired by, hundreds of miles away at Bosque del Apache. That site was the rising of thousands of white geese from a reservoir that was dammed immediately to my right. Because the light was fading my pictures were a sad display, but I will be back in the area again to try to do justice to what I was able to witness. Just incredible!
To that end, if any reader happens to know the area, please feel free to reply to let me know if the large processing plant on the south side of that reservoir has any public access to the lake? It is just south of County Rd Q, and west of the Brush Prairie Ponds SWA.
In the fading light I did head on, and reached my target road. I saw no one for ten miles, just two dogs that chased me for a mile or so, and one Red-tail Hawk. I wouldn't have traded the experience though. At one point I stopped to pull a jacket from the back seat, and got out just to listen to the silence. I wasn't rewarded with any sightings, but that didn't matter right then. Finally as I was returning to a paved State Highway and turning back to the interstate in the cloud induced early dusk I had a pair of Harlan's Hawks, one flying and one perched, in my area. A good sighting to wrap up my first of many visits to Morgan County. The hundred Ross's Geese I saw added one life bird to my list in force. I had hoped for photos, but there should be more opportunities as migration approaches.

Dark Bird - Darkly


While searching for gulls on Saturday I made a stop at Erie Reservoir. Gulls were out, but they seemed to be limited to Ring-billed, Herring and a couple of possible Thayer's. However this dark hawk arrived shortly after I had, momentarily making the deteriorating conditions a non-issue.


I wanted this to be the dark morph Rough-legged Hawk that had been reported in the area, but I can't say I was too disappointed to have so many looks at this Harlan's Hawk. I hadn't realized that they were so close, but note the light under-wing. On a dark Rough-legged the white should be more pure, especially at the wingtips. Here it shows a clear barred pattern. Another point to consider is the top of the tail. It shows very white, with the dark band at the tip. On a Rough-legged the tail would be more grey. Still, I was wavering until I took a close look at the picture below.


A Harlan's, or any Red-tail shows its large feet and long bare legs. Had this been a Rough-legged Hawk the feathers would have descended to its feet.

So, still no Rough-legged, but a real highlight nonetheless.

Sick



I feel a bit like the barn above. A little off kilter to say the least. Despite being the victim of the latest bug to make the rounds I did manage to get out for a short drive Friday afternoon in Weld county.



This Harlan's Hawk was trying to hold on to his feathers in the strong winds that were blowing across the plains Friday afternoon.

He was back in his element once he took to the air. I also saw an adult and juvenile Bald Eagle, and three Northern Harriers. Unfortunately no pics of those. My previous posts on the Norhtern Harriers have paid off. The tell-tale white rump patch really stands out when I look for it. I also saw these Eurasian Collared Doves perched on the wires. They are in the midst of a population explosion, having until recently been quite rare in this area.

Walden & Sawhill Ponds


Another great day at a location I found via the Colorado Field Ornithologists' Birding by County site. This time it was a pair of preserves in northeast Boulder called Walden and Sawhill Ponds respectively. They are managed by different agencies, and are separated by a small fence with multiple access points. For the wildlife they make one large habitat with numerous lakes, ponds and marshes.


After seeing many Ring-billed Gulls, Mallards, Canada Geese and American Wigeons I spotted a juvenile Bald Eagle soaring above me.
Later I saw two adults soaring hundreds of feet above a human glider being towed aloft by a prop plane. That would have made a great picture, but trees and distance prevented it.
I got over it quickly though when I finally spotted a Great Horned Owl. This has been my most frustrating species since I started listing. I had decent pictures of one last spring in the wild, and worked with them enough at Birds of Prey to have one mistake me for a tree, but had not seen one yet that I could confirm since last October. I knew that they were out there, and that when I did find one it would be closer than I expected.


Sure enough this guy was sitting directly behind me at eye level. When I first spotted him he was on my sunny side and I couldn't get much detail.


I gradually worked my way around him at a safe distance.


What a magnificent bird!


These two were swimming on a larger lake as the sun began to sink behind a storm cloud on the mountains, a good portrait of Ring-necked Ducks.
As I took their picture movement erupted across the lake.


Another Great Blue Heron!


Two on back to back days is a nice trend, hopefully this means more owls soon.
Immediately after I saw what may have flushed him, this cool looking intermediate Harlan's Red-tailed Hawk, (also pictured at top).


He would have had more than he could handle with a great blue, so perhaps they were flying coincidentally.....
either way I'll take it.


The contrasts in that bird are very nice.


An excellent place for birding, and the Great Horned is a nice add to the list.
