Some Thoughts on Bird ID


There are a variety of Facebook pages with countless posts asking the question “What is this bird?” with an accompanying picture that ranges in quality from a close up, crystal clear image to a distant, completely out of focus image. This seems like a totally innocuous question, but it can stir up a bit of controversy.

For some reason, we feel that if we know the name of something, we then really KNOW it. This of course is a complete fallacy, but is the impetus behind the question. As an example, if you show me a picture of a Brown-headed Cowbird, I can certainly provide you with a name. But you will not learn about the most intriguing aspect of this species. Brown-headed Cowbirds are brood parasites. They build no nests of their own, but lay eggs in the nests of other species, letting those birds act as foster parents to the Cowbird hatchlings.

The controversial issue surrounding a “What is this bird?” post is that experienced birders will help answer the question, but usually won’t answer it directly. They will provide clues, such as, “look at the white eye-ring and pink bill” or “what color are its legs?” This frustrates the person posing the question because they just want the ID. The experienced birder is trying to provide some education so that it is possible for the person to ID the bird in the future. Many experienced birders (myself included) began birding well before the internet existed and they had no other option but to spend time pouring through field guides and comparing “field marks” to identify a bird. This was time consuming and hard work. But they learned how to ID birds. They are trying to share their knowledge. So if someone asks the “What is this bird?” question, without making any effort to ID on their own first, they will likely get a little perturbed. However, if instead of asking “What is this bird?” you say, “I’m thinking this might be a Field Sparrow because of the color of the bill, but I’m not sure. Any thoughts or guidance would be appreciated.” you will likely receive a more timely and helpful response.”

And here is a mind blowing concept for some people, sometimes it is not possible to identify a bird. Things that make for difficult ID’s; bad lighting, objects such as twigs and leaves blocking key field marks or the bird is part of family of birds that can only be separated to species by song.

The key here is make an attempt at identifying the bird. You will learn in the process and more experienced birders are more likely to provide assistance. And the most important thing to remember is this, every birder has mis-identified birds at some point. I remember posting a photograph to a birding web site of an “American Golden Plover.” I was very proud of this picture, but the problem - it was a Black-bellied Plover. Several people gently pointed out the error. After getting over my embarrassment, I actually learned the difference between the two species and during a recent birding excursion I was able to confidently identify a Black-bellied Plover for some other birders.

Here is my "American Golden Plover" photo. Even with this poor quality photo
one can see the field marks that make it a Black-bellied Plover. Oops.

If you want to learn how to ID birds, get out in the field with some experienced birders. When they identify a bird, ask them what led them to that conclusion. You will usually get a detailed and well thought out response.

Keep in mind that no matter your experience level, you will occasionally mis-identify a bird in the field. This happens in the heat of the moment, often at your first, very quick glimpse of a bird and your immediate impression is wrong because you didn’t have enough information to identify the bird initially. It happens. Don’t let that bother you.

And if I see you post a “What is this bird?” query, I will do my best not to be rude. I will simply say, “It is not a Lilac-breasted Roller.”

My Patch

The Joys of Kingston Lake

There is nothing extraordinary about Kingston Lake Park in Johnson County, Kansas. Yes, it is an eBird hotspot, but species diversity is low, only 80 species have been recorded there. It is nothing more than a suburban backyard with a lake in the middle.  A handful of bald cypress can be found along the shore and there is a conglomeration of trees and shrubs on the fence line at the eastern edge. There are two benches, a small shelter, a playground area and several randomly placed picnic tables. There are no restrooms and U.S. Highway 69 runs along its eastern border. However, it is a mile from my house and I have submitted 62 checklists for Kingston Lake so far this year. It is one of my favorite birding locations. A species list can be found here.

What's the attraction?

If Kingston Lake is famous for anything, it would be ducks. Not large rafts of ducks, but handfuls of a variety of ducks that are approachable and can be studied without needing a spotting scope. And very often they will come close to shore which is something appreciated by local photographers. And should the lake freeze, there is usually an open patch of water directly in front of the western fishing dock where the ducks will congregate. The birds are frequently close enough that you can actually see the "ring" on the Ring-necked Ducks.

Another advantage of having a small group of approachable ducks is that it provides the opportunity to study the females. I have spent a great deal of time sitting on the bench at the south end of the lake looking at female widgeons, scaup, pintails, and ring-necked ducks. It has been very helpful.

What else?

While it may sound counter-intuitive, the lack of species diversity is another attraction. Right now, the ducks are gone and it is time to focus on migrants and summer residents. With only a handful of species there at a time, there are no distractions. I'm not jumping from one species to the next to build up a big list. I can focus on what is there. And there are few if any Tufted Titmice drowning out the calls of other birds. Recently, the trees were filled with Yellow-rumped Warblers. I could calmly watch them, but more importantly I could listen to them. I'm a nearly 60 year old man who was too fond of fireworks and rock music in his youth. Being able to listen to their quiet and high-pitched song was wonderful. I have had the opportunity to listen to (and observe) Chipping Sparrows as well. If you are at Kingston Lake at the right time of year, you can watch a variety of swallows cruising and swooping, which is not only enjoyable, but they fly close enough for you to see field marks and study tail shapes. But the real attraction is the same as with all birding efforts, you never know what you are going to see.

Patch birding

My trips to Kingston Lake started with my frustration at not being able to get out to bird on a regular basis. Since it is so close to my house I figured I could stop there to or from work, the grocery store, etc. I figured birding there was better than not birding at all. It has since become my local "patch." I'm  there from 5-7 times a week, with visits ranging from fifteen minutes to an hour. I pay close attention to new arrivals and recent departures. I have begun to notice other critters such as a muskrat chowing down right next the concrete sidewalk and the host of sunning turtles that show up out of nowhere when the weather is right. I'm hoping to learn to identify some of the trees and shrubs before the summer is over. Do you have a favorite "patch" to bird? It doesn't have to be a famous hotspot, it can simply be a place you find yourself visiting on a regular basis. It can be fun, although I have offended a few people by saying out loud, "What are you doing here?" when I spot an unexpected species. If you are not familiar with "patch" birding, you can learn more here.
