Bullock’s Oriole Building a Nest at Barr Lake State Park, Colorado /  by Todd Henson

Here a Bullock’s oriole is just leaving its nest

Oriole’s are beautiful and somewhat iconic birds. In the Northern Virginia area I’ve often seen orchard orioles while out hiking through the right environment, and occasionally in some areas I’ll see a Baltimore oriole. But that’s it. The other oriole species of North America are all further west or southwest.

The first thing I noticed was an empty nest

So when I had the chance to visit Colorado in early June (many years back) I was very pleased to run into a Bullock’s oriole working on its nest right along a main trail in Barr Lake State Park. I saw the nest first. All the photos of the oriole are cropped in quite a bit to let you see the bird a bit closer. But the photograph of the empty nest is just as it was framed at 230mm with a 70-200mm lens and a 1.4x teleconverter. So the nest was very close to the trail. But when I noticed the bird trying to come back to the nest I moved further back to give it space. And that’s all it took.

For whatever reason I struggled to identify this bird at the time. I wasn’t sure it completely fit any of the photos/descriptions in my field guides. It seemed a bit more yellow than orange which seemed to point towards a female or younger male (except for Audubon’s or Scott’s orioles, but it didn’t appear to be either of those). The blacks weren’t the stark blacks that photos of the males seemed to possess. The black goatee/chin seemed to indicate a possible male, though I read somewhere you might sometimes find a female with one and they’re thought to be older females. The narrowness of the goatee and the dark eye line pointed me towards the Bullock’s oriole, and a photo in National Geographic’s Complete Birds of North America shows a 1st spring male Bullock’s that appears to match my specimen, one that is just starting to develop the stronger black markings. And it could be complicated by the fact that Bullock’s and Baltimore orioles do sometimes interbreed (hybridize) in areas where their ranges overlap. Colorado seems more the Bullock’s range but the Baltimore’s range isn’t too very far east, so maybe? Probably not as that overlapping range is apparently a narrow one.

The more I thought through all the field markers the more I kept leaning towards a Bullock’s oriole given the area where I found it, but I wasn’t willing to accept my own identification until years later when I ran two different bird identification apps against each of the photos and both apps identified them as a Bullock’s oriole (Icterus bullockii). And so I believe this bird to be a young, perhaps 1st spring, male Bullock’s oriole. But if you feel I’ve misidentified this bird then please leave a comment letting me know what you think it is and why, what identifiers or field marks you used to identify it.

Interestingly, at one point in time the Bullock’s and Baltimore orioles were thought to be a single species and at the time were called northern orioles. But as happens, they were later differentiated based on DNA studies and other criteria. The name Bullock refers to William Bullock, an English amateur naturalist.

I was so fortunate, not only to find an oriole species we don’t have back east, but to find one working on its nest. I love finding birds in and around their nest. You can see such incredibly interesting behaviors, as visible in some of these photos.

I love this view of the Bullock’s oriole completely inside the nest with just head and tail showing

I hope you’ve enjoyed this look at a Bullock’s oriole working on its nest, as well as some of my struggles with identifying it. Have you ever seen this species of oriole, or any species of oriole? Let me know in the comments below.

Resources

Below are the three field guides I used most when identifying the Bullock’s oriole. Of them I found the National Geographic Complete Birds of North America the most helpful. It’s by far the largest book, not a guide you’d take out into the field, and that gave it the extra space to show some extra photos which made a big difference for me.

Colonial Beach in Winter /  by Todd Henson

A little snow remained at the Colonial Beach Municipal Pier

In mid-January my father and I went for a drive and found ourselves at Colonial Beach in the Northern Neck of Virginia. This is a popular summer destination for some folks but isn’t very popular at all during the colder months of winter, which means I found it far more appealing in winter. Snow had fallen about a week before and though most of that had melted there were still some small amounts on the pier and beach.

Over to the left was what I called cormorant pier for all the cormorants perched along the length

It was a cold day but not frigid. And there were hardly any people about, though we encountered many gulls and cormorants as you can see in the photos. The weather forecast had called for a small chance of rain in some areas of Virginia, and though we didn’t run into any it did result in some nice overcast conditions and clouds with a bit of character. Overall I found it a very calm, quiet and beautiful day and I’m glad we decided to pay the beach a visit.

Juvenile Yellow-crowned Night-Heron /  by Todd Henson

A juvenile yellow-crowned night heron

Some species of heron seem very common in the greater DC area, such as great blue and green herons. But night-herons rank among the species I rarely see. They tend to be a bit more secretive, perhaps more often out hunting at dusk and night, though as these photos show, they can also be seen by day.

Juvenile Yellow-crowned Night-heron

What we have here is a juvenile yellow-crowned night-heron. There are two species of night-heron in the area, black-browned and yellow-crowned, and if these were adults you’d more easily see why each is named as they are, though the yellow crown on an adult may be difficult to see. Adults are very distinctive and easy to identify. But the juveniles can look very similar. This one is more grey and has various markings on the feathers that help identify it as yellow-crowned.

In late July of 2008 we found several of these juvenile yellow-crowned night-herons walking the pathways around the pools at Kenilworth Aquatic Gardens, in Washington DC, where they grow lotus and water lilies and where large crowds gather to see the blooms each summer. Night-herons may be more secretive, in general, but given these were juveniles and that they seem to have hatched in an area where many people gather, they were very bold and unafraid, seemingly ignoring the people and focusing on the water and any prey they could find.

Technical Note

A quick technical note to admit to my mistakes and to demonstrate that even when we make mistakes it’s often possible to salvage something of value from them (beyond the obvious learning opportunity). On a previous photo session I’d been photographing in a very dark area and had my camera’s ISO set very high (1000 was high at the time). I’d forgotten to set it back to normal when finished, and I’d forgotten to double check my settings before setting out this morning. So for much of the morning I kept wondering why I was able to achieve such high shutter speeds (1/8000 second). Well, it’s because my ISO was set way too high for a bright sunny day.

Lessons Learned

So, what lessons did I learn from this experience and from the mistakes I made?

  • Reset my camera settings to my typical values after each photo session. That way I have a known place to start from next time I pick up the camera.

  • Always double check my settings before my next photo session, just in case I’ve forgotten to reset them. This is when I can also change the settings to suit whatever environment I’m going into if I know to expect a certain level of light.

  • If something seems off in the field, such as unusually high shutter speeds, then stop and double check all my settings. I could have found my error and corrected it much sooner.

  • It’s often possible to salvage worthwhile material even after making what seems a stupid mistake. Granted, these photos will never be as technically good as they could have been. I have lost some data to noise. But thankfully it was a bright sunny day with few dark areas so the noise was surprisingly minimal and I was able to pass the photos through Lightroom’s noise reduction process to lessen the digital noise introduced by the high ISO. The photos work perfectly well for a blog post showing off a species.
