2020 Bird Wrap-up
Here’s a bit of a wrap-up on 2020 with a selection of miscellaneous birds that didn’t fit into any other blog posts.
I likely have several other bird photos from 2020 that need processing, but this is all I have for now. Thanks for the visit.

White-eyed Vireo Nest – Part One
May seems such a long time ago. I don’t know how I get so behind on photo processing, but, better late than never. Here is the first of what will probably be three videos with stills of the White-eyed Vireo nest found by Miguel Acosta at Weldon Spring C.A. this past spring. I hope you like it.

North Carolina Birding – 2019 Wrap-up
Going to the archives to try and wrap up 2019, I want to share a few more birds taken in eastern North Carolina.
For me, the highlight of visiting Pea Island National Wildlife Refuge was visiting the Least Tern nesting colony. They put up a barricade to make sure you do not get to close to the nests and chicks, but it soon became obvious that the birds do a pretty good job at dissuading anyone from getting too close.
It was terrifying watching these birds react defensively, strafing and defecating until I moved back to a point they felt comfortable with. I remember I still had some of their ammunition on my camera body for at least six months before finally cleaning it off.
You have to look really close towards the center of their nesting arena to spot the chicks – the reason for their territorial behaviors.
During a walk along the interior, marsh portion of the refuge, this beautiful Common Tern flew by.
A real treat were my first looks and photographs of Red Knot.
During the same trip, I was fortunate to visit a nice longleaf pine forest habitat at TNC’s Calloway Forest Preserve in Hoke County, NC. Here, along with the Red-cockaded Woodpecker, I got to find one of my southern favorites, the Bachman’s Sparrow.
From the few short trips I’ve been, North Carolina seems to be quite a place for birds and nature.

The Ruff
Camera settings: f/8, 1/1000 sec., ISO-640, 1120 mm focal length equivalent.
Never have I worked so hard to get mediocre photos of such an ugly bird. The sky was clear, the air cool and this combination created a terribly turbulent atmosphere over the mud flats the bird was foraging in, making it near impossible to get the sharpness desired in a photograph.
The Ruff is a bird that is native to Eurasia, visiting North America somewhat regularly. There have been sightings of this species in Missouri and Illinois in the recent past (at least three during this spring), but this is the first one I’ve been able to track down and photograph. Josh Uffman happened to discover this bird near Riverlands Migratory Bird Sanctuary on April 18th while we were in the area. I want to thank Josh who turned on the St. Louis birding community to this special visitor from overseas.
The Ruff is a member of the Calidris genus of shorebirds. Local members of this group include many of the sandpipers we are familiar with, like the peeps, Dunlin and Red Knot.
I know I called this particular bird ugly earlier in the post. However, if you are not familiar, look this bird up on the internet or your favorite bird guide. The birds in breeding plumage are absolutely stunning and their behavior on leks makes them a very special bird.
These were just a few of the couple thousand or so photos of this bird taken on that day. Most were boring shots of the bird foraging in the flooded farm field. Perhaps one day I’ll be fortunate enough to see these guys on their leks.

Backyard Birding – Missouri Winter Songbirds. – 01/12/2019
An excellent post by Miguel Acosta using photos he captured at my backyard feeders.
A big thanks to the Duncan’s for inviting me to their home, to photography winter songbirds at their bird feeder.
A cold winter day is perfect for curling up by your living room or you can stock your bird feeder, get your camera, a turkey chair and check out the activity at the feeder.
Here’s a quick rundown of the most common backyard birds, I saw while spending an afternoon at my friend’s bird feeder.
House finch – love Nyjer seed, often mistakenly called thistle seed. Offer it in tube feeders or net bags, and watch these colorful birds swoop in for a visit.
Woodpeckers – In the winter, beef suet is an energy-rich substitute for the insect fare that downy, hairy, and red-bellied woodpeckers feed on during the summer. Other bird species such as jays will also eat suet, but it’s…

WGNSS Natural History Photo Group Field Trip – January, 2019
The WGNSS Natural History Photo Group had a fun field trip in January, when we headed north up the Mississippi to the riverside town of Clarksville. Here at lock and dam #24, we were fortunate to be alongside ~75 eagles of various ages that took turns in catching the stunned shad that is their primary winter food source along the great river. We arrived early in the morning and made a day of it, experiencing wide shifts in weather from grey and snowy to partly sunny skies. I’m not an expert in aging these eagles, but I believe the bird picture above is a subadult II, which means it is 2.5 – 3 years old. In this photo you can see several retained juvenile secondaries on each wing.
The long and pointed secondaries make me think this bird is probably a year younger than the bird in the previous photo. I would guess this bird is 1.5 – 2 years old. The temperatures on this day were cold, but not too severe. We arrived with the car’s thermometer reading 16°F. There was a light wind most of the day, but not nearly as bad as there could have been.
With patience, there were some opportunities to capture a bird’s profile as it came to pick up a poor stunned fish.
The majority of prey captured in this way is small enough to be eaten immediately on the wing in a single “bite”. Sometimes, however, the bird is forced to retreat with its groceries and eat in seclusion.
The bird pictured above is much closer to looking like an adult bird, showing the mostly white head and tail. I estimate this bird as being 3.5 to 4 years old.
I noticed this in previous years, that it seems like the juveniles spend more time fishing than the adults. In the photo above, you can see a juvenile with an already full crop is pulling another fish from the river.
This is just a few I have processed so far. We have something in the works that may produce something much more in terms of eagle photography. Until next time.

Comparing Canon’s Newest Teleconverters
Image made with Canon 7d mkii, Canon EF 500mm f/4L IS II USM Lens and Canon Extender EF 2X III
I don’t usually like to discuss gear on this blog, but once in a while I think there are some things new or interesting enough to talk about, particularly when I think they may be critical for producing the best possible results. I have been wanting to test and compare the 2 latest Canon teleconverters (Canon Extender EF 1.4X III, Canon Extender EF 2X III) in a head to head test for sometime and this past weekend found me with an opportunity to do so. To be clear, this was not the optimal situation to make this test. The light was poor and the subject was probably too far away and not covering enough pixels to make a relevant comparison. But, I thought I’d give it a try.
These tests were setup as equally, but not scientifically, as possible. For these first two images, I processed as normal and tried my best to be equal in all capture and processing steps. I cropped to make the bird approximately the same size in both images, so obviously, the photo made with the 1.4X tc was enlarged more than the one made with the 2X tc. I then resized each to make them 1000 pixels on the horizontal. The purpose here was to see if there is a discernible difference in sharpness and image quality between the two. The 2X tc often gets poor reviews, but just as often gets raves by those who claim to know what they’re doing. Many claim that the better results are made by using a 1.4X tc, or native lens and cropping in post to obtain better results than those obtained by using the 2X tc for an optical zoom.
Open the two images above in separate tabs to see a roughly equal comparison. In my opinion, I was pretty pleased with the results of the 2X tc in sub-optimal conditions. Both photos are fine for sharing on the web, although the IQ would limit print size. Like I said, the conditions were poor and the bird at a great distance. However, I think I would give a slight edge to the photo made with the 2X converter. This edge might just as well be due to differences in how I processed or with changing conditions within the few minutes between captured images.
Let’s look next at the “100% crops” of both photos. This simply means that these photos were both cropped at the same dimensions (4″ x 6″) and not resized. These examples were NOT sharpened.
Again, with this comparison, I find the two very close. Either one would work well enough, but if your goal was to maximize print/display size, I would probably go with the 2X tc. I guess this has surprised me a bit. I was expecting that, under these sub-optimal conditions, the 2x tc would fall behind the supposedly sharper combination of the 500mm + 1.4X tc.
What do you think? Did I make any major blunders in my comparison or analysis? Please let me know. I do hope to make this comparison again under perfect light and optimally placed subject sometime in the future.
Thanks for stopping by and reading this far!
