Harrison Bald Eagles

Bald eagles feasting on salmon near Harrison Mills, British Columbia
This past weekend, I joined Michael Russell of Michael Russell Photography for a trip up to the Harrison Mills vicinity in British Columbia to view and photograph the annual bald eagle visit. Billed as one of the largest congregation of bald eagles in the lower mainland, up to 10,000 eagles descend upon a 2 kilometer stretch of Harrison River where it meets the Chehalis River. There’s an official festival in honor of their return during late November but the actual eagle counts are at their highest during the weeks that follow.

The eagles are spread out over a vast marsh / estuary so there isn’t one spot to visit for viewing. As the stories usually go, the eagles typically hang out at large distances away from the road or the limited viewing locations behind the Eagle Point housing subdivision. Thankfully for me, Michael has been in the area before and had a few ideas for stops which I otherwise would not have known about. We were also blessed with dry (but cold) weather during our visit.

On our drive east to the Harrison Mills vicinity, we counted a number of eagles along the slough which parallels Highway 7 between Dewdney and Derouche. We eventually stopped along Morris Valley Road a little bit north of the Sandpiper Golf Course. Here we were treated to a dizzying display of activity. A core group of a dozen bald eagles were feasting on salmon along a small channel and were surrounded by dozens (if not hundreds) of sea gulls. Scattered through all of the trees surrounding this open area were even more eagles surveying the scene.

The skies above us were always dotted with a soaring eagle or sea gull and there was never a dull moment. The banks of this channel were littered with the bones of hundreds of dead fish and yet there were still more salmon swimming in the clear water. We enjoyed this spectacle for nearly an hour until it every bird was spooked into the air by three hunters walking across the estuary on their way back to their vehicles. This was a definitely a bummer but it did force us to look elsewhere. We decided to drive a little further east to the bridge over the Chehalis River. On the way, however, my girlfriend spotted an eagle sitting atop a solitary snag in a wetland. After finding nothing along the Chehalis, it was an easy decision to double back to that solitary eagle.

The snow-capped top of Mount Woodside made for a nice background behind the eagle. After exhausting our opportunities here, we doubled back to the Eagle Point subdivision to check out the observation viewpoints along the edge of the Harrison River. As we reached the first viewpoint, we had an encounter with THAT guy. You know THAT guy- he’s the one with the expensive gear and has no time (or patience) for anyone except himself. In this situation, this photographer had two Nikon pro bodies, a three foot long telephoto prime lens, a Jobu gimbal head, and an attitude big enough to handle two bodies at the same time. Here’s how the conversation went as we came upon him taking up the center portion of the viewing platform:

Us: “How’s it going? Find any good viewing locations?”
Him: “For what? Moose? Bear?…”
Us: “uh, Eagles..”
Him:(pointing above and behind himself without looking to a tree with eagles) Over there.”
Us: “ok, thanks.”

I wouldn’t expect something to give up info about a secret spot but there’s absolutely no reason to be a complete Richard to someone else. This guy could have said anything to us but chose to be a smart-ass. After that wonderful exchange, it would come as no surprise that he eventually appeared at another spot we were set up at and walked around and in front of us without any concern about any shots we may be taking. Someday, karma will catch up with this guy…

The day was nearly over but there was still enough time to check out Kilby Provincial Park. While there weren’t any eagles at the park, my girlfriend once again noticed a couple eagles feasting on salmon alongside the Highway 7 bridge over the Harrison River. As our last gasp of the day, we doubled back to the bridge. There are some trees along the road which I thought would conceal our arrival; unfortunately, most of the birds present moved on the minute we stopped. Luckily, a lone eagle perched atop a piling stuck around and posed for us for a few minutes longer.

After that, I chatted with Michael for a while before the cold and other time commitments prompted us to part ways. Every time I visit Canada, I’m humbled by it’s vast beauty and diversity. I’m hoping to return later this winter to check out the snowy owls near Boundary Bay. Special thanks once again to Michael Russell for playing tour guide during our outing! If you haven’t check out his work, please visit his website.

Yellowstone National Park

Sunrise over The Thunderer and Soda Butte Creek, Yellowstone National Park
Grand Prismatic Spring in the Midway Geyser Basin, Yellowstone National ParkThe week of Labor Day marked my first ever trip to Yellowstone National Park. I’ve actually wanted to incorporate a little more wildlife experiences in my photography the last few years. Heck- if you’ve ever looked in my “fauna” gallery on my site, you know it’s pretty bare! Anyways, my girlfriend stopped through the park back in June and was all too eager to make a return trip. Away we went!

Unlike most of my blog posts where I typically write up a journal or narrative for my outings, this time I just wanna rattle off a list of random thoughts-

Trip Research / Prep!

There are a couple of traditional print books about photographing Yellowstone such as this and this. I have both, and they’re not too bad (but a bit light on wildlife). Prior to my trip, I came across an eBook put out by photographer Dean Sauskojus (website here) called “The Ultimate Photo Guide to Yellowstone National Park” (and you can access the eBook info page here). Dean’s photography is wonderful, and his locational write-ups seemed to be fairly spot-on. I found it handy to be able to refer to the PDF on my tablet while out in the park. Anyways, I would definitely recommend the eBook.

Morning Light on Mount Hornaday from Round Prairie, Yellowstone National ParkAnother tidbit of advice I had been told prior to my trip which I found true was that the distances between points takes a lot longer to travel than you might think. You might want to estimate up to 1.5x the amount of time you think needed in order to get between places by the time you want. You hear about “bear / buffalo jams” but we didn’t experience anything severe during our stay. It could just be the tendency to gawk as you drive, or just being extra defensive to avoid being surprised by something on the road. Case in point, we were driving back to Tower Junction after sunset on our last night and seemingly out of thin air, a small herd of bison was partially in the road, including a young bison nursing off mama.

I’m here! Now what?

One thing I’ve learned to do over time is to scale back expectations of what you can accomplish during the course of a day. Every day I had a sunrise and sunset spot selected but only a very loose plan to connect the two together. Let your hunches and curiosity tell you when and where to stop. Tangentially related, get some bear spray for your safety and protection. It’s designed for use against an attacking bear but any large wild animal can suddenly turn aggressive towards you. This video shows a bunch of teen and pre-teen jack-asses who have a run in with a bison (I would hope most of you wouldn’t be that foolish, though!). At one of my stops near Grand Prismatic Spring, we passed a solitary bison laying down near the Fairy Falls trail. As it turned out, the bison had a wound in it’s side from a sparring match with another bison. A wounded animal can be a dangerous animal and the bear spray was a reassuring item to have.

If you do happen to stop someplace, be prepared to draw a crowd. I’d like to tell you that the crowd will be animals but more often than not, it will be your fellow tourists. They end up deciding that you MUST be seeing something! After all, why else would you have stopped?? I was photographing Soda Butte Creek and Barronette Peak from the highway bridge over the creek when a car stopped on the bridge behind me. I initially ignored them but then a voice asked, “you looking at an animal of the view??” I answered “the view” and they immediately drove off.

Sunset over the evening Bison commute in Slough Creek valley, Yellowstone National ParkNow, sometimes where there’s smoke, there *IS* fire. A few times, we pulled over (into an accepted parking spot) when we came up on a scene with dozens of other people park and gawking at something. The first time in the Lamar Valley, it was the appearance of a black wolf; the second time was in the Hayden Valley and there were up to four wolves in a chess game with a herd of bison. I guess my moral of the story is to let small groups of people enjoy themselves, if you can.

When you are out driving around, be sure to have your camera immediately available. Getting stuck in a bear or bison jam may give you an opportunity to get a nice close shot that you might otherwise
miss. We were stopped in one brief traffic snarl and off to our right was a fox hopping and hunting some prey in the field. While we were stopped, my girlfriend was able to snap a couple shots of it. Another time, we were driving back down from the Beartooth Highway and we passed a fox, happily trotted up the road with a fresh meal in its mouth.

Some Closing Thoughts

I came home from Yellowstone with about 1,400 photographs. Most of these were rapid “bursts” in order to capture some sharp shots of wildlife. After reviewing them, I still have some work to do with my use of a “wildlife” lens like my Bigma (the Sigma 50-500mm lens). This week I came across a few sites which discuss what’s known as long lens technique (this, this, and this) and I’ll be working to incorporate these techniques before my next visit to Yellowstone.

Boundary Bay Owls

There has been a lot of press lately about the large migration of snowy owls down into the continental U.S. Every once and awhile (known as an irruption), their numbers really spike and this happens to be one of those years. As it turns out, one of the big “hot spots” for them is just across the border in British Columbia at Boundary Bay near the town of Tsawwaassen. Some friends of mine visited a few weeks ago which got me curious and I did some research. Lots of owls, sitting around, not far off established trails- my kind of wildlife photography!

Originally, I was just thinking about a day trip to Boundary Bay. My girlfriend suggested that we make it an overnight trip and that turned out to be a GREAT idea. The main congregation of snowy owls is found near the end of 72nd St, along the raised dike. From the 72nd St junction westward to 64th St, the snowy owls are generally found resting on top of the driftwood pieces that tides have washed up against the base of the protective dike.

For the most part, the owls seem to tolerate the HUGE influx of admirers viewing and photographing their stay. The majority of visitors stay close to 72nd St (site of the largest gathering of owls) but folks willing to walk further west along the dike towards 64th St will also see more owls, bald eagles, great blue herons, and other wildlife. Even fewer people travel east along the dike from 72nd St but don’t let that stop you! I found a couple snowy owls (without any one around) along with a great blue heron and more bald eagles.

As longtime visitors to my blog can tell, I’m a landscape/nature photographer first & foremost. Any wildlife I have previously photographed has usually been the result of being at the right place, right time. In the last year, I purchased a Sigma 50-500mm lens (also known as a “Bigma”) and a gimbal head in hopes of adding more wildlife photos to my portfolio. We arrived at Boundary Bay during the late afternoon and were able to get a parking spot somewhat close to the dike since people were beginning to leave.

The weekend’s forecast was for sunshine and 50 degree temperatures but that was quickly changing at Boundary Bay. A thick maritime fog was advancing towards us from the Strait of Georgia. Eventually Mount Baker disappeared from view and reduced visibility settled in. Although there would be no sunset, the conditions did offer an opportunity to capture some unique photographs. We turned around at 64th St and made our way back to 72nd St. The failing light really provided a challenge since my Sigma is a F6.3 @ 500mm. Thankfully, the low light and higher ISO capabilities of my Pentax K-5 were up to the task.

We got back to my truck well after sunset and the place had pretty much cleared out for the day. Along the way back, however, we were treated to some owl activity such as perching even closer to the dike trail and some flyovers. We traveled the back roads towards Tsawwaassen where we spent the night at the Coast Hotel (recommended!). The next morning, the skies were clear and I was excited to head back in time for sunrise. I had expected a number of wildlife photographers would already be present at Boundary Bay but that wasn’t the case. In fact, we were the third car to show up!

I quickly suited up and we were off. For my sunrise shots, I decided to head out into the marshy, grass filled near-shore environment. It was cold enough over night to frost which made travel a little easier. As you get to the mudflats, there are some beautiful S-shaped tidal inlets which perfectly reflected the developing light show. Although the skies to the east over Mount Baker were devoid of clouds, the skies to our south had a series of high, wispy clouds which began to reflect the warm light of sunrise. It was truly one of my favorite sunrises of the year and the fact I was able to photograph it and enjoy it with my girlfriend made it even better!

Sunrise began to develop quickly and eventually the sun rose above the horizon between Mount Baker and the Twin Sisters range. The wildlife photographers were beginning to show up in numbers as the light improved. My girlfriend decided to head east along the dike from 72nd St as I decided to head back to the owl concentrations west of 72nd St. I’m going to save any commentary about the behavior of wildlife photographers for another blog post but I was saddened.

I headed further west towards 64th St to get away from the photogs and returned to a large tree alongside the dike which the day before held up to three snowy owls. On this day, two bald eagles were enjoying the high ground. My only experiences with bald eagles are along the North Fork Nooksack River near Mosquito Lake Road (east of Bellingham) and in that area, the eagles tend to “spook” quite easily. At Boundary Bay, the experience is quite the opposite.

I approached the tree in several stages, taking photos along the way. I really thought that they would fly away but they didn’t. In fact, a woman walked right up to an interpretive display near the base of the tree and the eagles did little more than look down inquisitively. After getting my fair share of eagle photos, I headed back to 72nd St and then further east to meet my girlfriend, who had been calling me throughout the morning about all the wildlife she had been seeing along the dike. Sure enough, I kept seeing what she had.

We eventually returned to 72nd St around 11am and it was rapidly turning into the circus we witnessed the day before. I took a couple more photos (which filled my memory card) and I took that as a sign to leave. After gathering our stuff and checking out from our hotel, we spent a little time to explore the ag fields near Westham Island and Ladner. We were both pretty tired so we made the drive back home, returning just in time to see the kickoff for the Super Bowl. Ok, that last fact made *ME* happier than my girlfriend!

This was a great place to visit and I’m sure we’ll return, even when the snowy owls have left. This was also my first good outing with my Bigma lens supported by a gimbal head. The vast majority of the photos in this blog post were taken with the Bigma and I’m pleased. It’s not the fastest lens at F6.3 on the longest end but the high ISO capabilities of the Pentax K-5 can make up the difference. I do need to dial in the set up of the gimbal head because I still experienced some vibrations of mirror slap while taking photos..

(You’ll notice the terms “TRAIL PHOTO” and “OFF-TRAIL PHOTO” with the picture descriptions. I’ll explain this in an upcoming blog post about wildlife photographers)

Bigma Fun

Sigma 50-500 'Bigma' mounted to my Pentax K-5
I recently ended a long quest to pick up my “wildlife”zoom lens. As a brand, Pentax has not kept up with developing long length zooms (or primes for that matter) for use in wildlife photography. The Pentax branded lenses out there hail from the end of the days of film and the FA series of lenses. For modern times, options are really limited to a few offerings made by third party lens developer Sigma.

Sigma has been producing their 500mm (750mm equivalent with the Pentax 1.5x crop) beasts for a while and their offerings boil down to the 150-500 or the 50-500, which is affectionately known as the “Bigma.” Based on my research, the 50-500 was held in high regard for both it’s image quality and value. The current version of this lens retails for about $1600 in a Pentax mount and uses a HSM motor for focusing. Pentax’s own lenses with HSM motors have been suspect so I wanted to avoid this and target a used copy of the previous version of this lens (the 50-500mm F4-6.3 APO DG).

I thought I had scored a deal on one using eBay but the seller had mistakenly listed their Nikon mount lens as a Pentax mount.There’s nothing worse than opening a box and realizing the lens you see won’t fit your camera! Anyways, fast forward a few weeks and I found an individual selling their one year old Bigma for $825 on a Pentax forum. For an additional $50, the seller threw in a UV and Polarizer filter so I jumped on it.

I’m not really a wildlife photographer but occasionally find myself in those kind of situations. What’s more, there have been a few times when I knew that the extra length beyond my normal 300mm tele would have yielded a much stronger composition and image. I’ve wanted to take this lens out for a spin but haven’t had the time until a few days ago. I tried stopping by the Mosquito Lake Rd bridge over the North Fork Nooksack River but there wasn’t a single Bald Eagle to be found. If I was going to use this lens, it would have to be landscapes.

Before that, however, I stopped briefly at Nooksack Falls. I hoped to get a “wintertime” counterpart to my ladder-aided shot of Nooksack Falls from last summer. To my disappointment, much of the snow that fell a couple weeks ago has melted away..

After that, I continued up the Mount Baker Highway to hit the slopes at the Mount Baker Ski Area. The skies were partly sunny with clouds drifting in and around the neighboring peaks. Perfect for dramatic photos! I decided to only use the Bigma so all of these photos were taken with the 50-500 and a UV filter:

I’m really happy that I picked it up. It is a HEAVY lens and weighs in at over 4 pounds. I won’t be taking this out on a hike very much! Another caveat is its construction so you should be mindful of its use during extreme conditions. Living in the wet confines of the Pacific Northwest, I’m very accustomed to being out in rain and snow. My camera body has weather seals but my lenses do not. I have not found this to be an issue overall but the Bigma is put together slightly different.

Front most element is retained by six screws to the barrel. I would have concerns about water penetrating this seal and take some precautions
Six screws retain the front most element of the lens to the rest of the extending body of the lens. Given our proclivity to rain, I’m real concerned about moisture penetrating this seal. Thankfully, I have found an inexpensive solution but I’ll blog about that after I have had some time with it in actual rainy conditions. My Manfrotto ballhead can support the weight of the lens and camera but it is sensitive to vibrations. Using the camera’s timer or better yet a remote control helps mitigate for this.

The extra 200mm at the extreme end of the range does make a difference. There’s been one composition out along the Shuksan Arm that I’ve wanted to shoot but have been unable to since it won’t fill the frame at 300mm. It now does and hopefully I’ll be able to shoot it before the end of ski season next month. Focusing is fairly fast and snappy but it has hunted for focus in low light and low contrast conditions. I’ve been able to work around this by either selecting a higher contrast focus point or by pointing the lens at a higher contrast portion of the scene and then recomposing for my original scene.

The Canon / Nikon versions of this lens have a few switches near the mount which control zoom creep and manual / auto focus. The Pentax version only has the zoom lock switch and I gave myself a heart attack as I unintentionally discovered that manual / auto focus is controlled by a push/pull of the focusing ring. I thought I had broken the lens!

My last comment is about the lens hood, which requires some consideration. The horizontal petals almost half the depth of the vertical petals, presumably to avoid appearing in the frame at 50mm. My very first attempt using this lens was at a local estuary wetland during a windy rain. Although I was perpendicular to the wind, it was blowing water droplets in and onto the front of the lens. This is something I have not encountered with my Pentax DA55-300 which uses a lens hood with a uniform, deep length. This isn’t calamity by any stretch but I think folks should be aware of such things. Sometimes the photos we take can’t be duplicated so I would hate to loose a photo because I didn’t check for water droplets!

[UPDATE] I haven’t had many opportunities to use this lens until recently when I visited Boundary Bay in British Columbia to photograph the Snowy Owls. You can see those photos in my blog post here.
