What Is It? (Round 5)

Note: make sure to read the post "Be Patient... Or Not" and try out the real-life birding challenge included there.

Congrats to Gloria and David on identifying last week's Yellow-rumped Warbler (and nice job considering subspecies)!

Note: If anyone needs a field guide during school hours, just ask me.

   So now on to Round 5; We've got some fun ones this time... birds that are hard to see--and even harder to photograph! Camouflage, thick vegetation, and fast movement make the birds here tough to get a good view of, so you'll have to identify them on minimum amounts of information. As usual, I highly recommend that you use "view image" too see these photos full-size. Ready? Answers for both species are due by Halloween (that would be October 31st)!

Our first species was on a mountainside near Tucson, AZ. The first step is finding the birds!

     The next three photos are all of the same bird in a marsh in South Padre Island, TX. The fact that it was evening and starting to get dark out didn't help my photography efforts.
My first attempt resulted in this: At least you can see its tail. Sort of.

 Argh! Got the whole bird, but it's blurry...

There! It's in focus! Got it! Well, at least its rear end is. And it's really dark. Oh, well.

Trust me, there is enough information in these photos to identify both species.

Have fun!

What Is It? (Round 4)

Two things of note to start off with:

1. Make sure to read the post "Be Patient... Or Not", which is an actual posty post and not one of these little ID challenges. It offers advice on how to see more birds if you have very little birding experience.

2. We've got a modifications to how "What Is It?" works: in order to be completely sure that everyone's' identifications are based off of their work and not just reading others' posts, once I see that you have commented with an answer I will mark it as "spam" and it will not be visible. Once that particular round of "What Is It?" is over, I will "unspam" all of the comments and they will be visible again.

Now with that out of the way,

Congrats to Gloria, David, Roberto, and Evan on their ID's of last week's Little Blue Heron (Egretta caerulea) and Tricolored Heron (Egretta tricolor)!

Once again, I will say that the Uni library has two bird field guides that you should make use of when trying to identify species. Also, I will have a field guide on hand during blog reading/writing days if you just can't be bothered to check one out from the library.

So on to round 4!
     This bird is a bit less distinctive than last week's herons. Get used to it. I'll be kicking the difficulty level up another notch next time.

     Anyway, this little guy was at a "water ranch" in Gilbert, Arizona in mid-March.
    
     You have until October 24th to post an ID of this bird.

Have fun!

Be Patient... Or Not.

     One thing I hear a lot from people who I am trying to turn into birders is that they don't have enough time/patience/focus/whatever. I'll admit that in some ways this is a valid argument, especially for beginners. For someone with no prior birding experience, identification requires getting a really good look at the bird in question. For that to happen, you need the bird to sit out in the open, stay still for long enough for you to get your binoculars aimed at it, and show off some of its more definitive plumage patterns. Birds tend not to behave in such a way. If that's not bad enough, beginners haven't fine-tuned their vision to pick up on small bird-type movements (I'm really not sure how to describe this--there are just some things that look like the way a bird moves or the way the branches shake when a bird lands there), so they often notice fewer birds in the first place.
     Since cooperative birds are so infrequent, it can take a long time for a beginning birder to find one. Thus quite a bit of time and patience are required if you want to start birding by yourself. Luckily, there are a number of remedies for this:
     1. Choose your habitat wisely. Certain areas and environments make it just plain hard to see the birds that are there. Mature forests and dense underbrush may have thousands of warblers flitting to and fro, but you aren't likely to get a decent view of them when they're buried behind hundreds of leaves that are just as big as they are. The best habitat for beginner birders is, unfortunately, not one we have a lot of in central Illinois: marshes and other wetlands, the wetter the better. Go watch some ducks and herons. They're big, relatively slow-moving, and sit out in the water where they're easy to see. They can also be really interesting, especially if you catch some of them in the process of feeding. Also, while you're watching waterbirds, keep an eye out for anything unusual that might show up along the water's edge. You can check out the "Local Birding Sites" page of my blog to see recommendations as to where to go. As far as wetlands go, Curpros Pond is your best bet for good birding.
     2. Put up birdfeeders! These provide excellent viewing opportunities of backyard birds like cardinals, sparrows, finches, and doves. Try to have a variety of the kinds of food that you offer. Seed mixes often have a list of birds they are specific to, but anything with sunflower seeds is a good bet for the majority of species. Goldfinches love "sock feeders" with small thistle-type seeds. In winter, considering putting out suet cakes (solid beef fat often combined with seeds and mealworms) and whole peanuts to attract woodpeckers, nuthatches, blue jays, and, depending on where you live, chickadees and titmice. In general, birds are more attracted to feeders in winter because food is scarce elsewhere.
     3. Go birding with someone who has lots of experience! "Serious" birders can point out birds and identification features that you would otherwise miss, and often know exactly where to look for certain species. I used to be a raw beginner, but the local Audubon Society has raised me well. Keep an eye out for any of my email announcements of birding events, and consider attending a few Audubon Society birdwalks, the last two of which for this year will be from 7:30-9:00 starting at the Anita Purves Nature Center in Urbana on October 21 and October 28.
     4. Practice! One thing I can't stress enough is that birding gets more exciting the better you are at it. Most of all, learn how to aim binoculars quickly and accurately. Once you can do that, you'll start getting really good views of birds that don't sit still very long, notably warblers.

     Aaaand, just as some encouragement, I have a little challenge. Go birding somewhere (anywhere, even your own backyard) for 15-30 minutes, and keep track of all the species you see. Post a comment with where you went and a list of species you saw. How many can you find?
    Oh, and photos are welcome, too. Especially if you're not quite sure what kind of bird it is.

    Happy birding!

What Is It? (Round 3)

Okay, I'll confess that Round 2 may have been a bit challenging. However, Gloria and Roberto both correctly identified the pair of Double-Crested Cormorants (Phalacrocorax auritus). I let it slide this time, but from now on it's your most recent answer that counts when I tally up the score at the end. Interestingly enough, there actually was a Neotropic Cormorant at Horicon while I was there a few years back, but these two are too big and not skinny enough to be the Neotropic (plus, there was only one Neotropic there).

No one correctly identified the third bird, but this one was especially hard for a number of reasons:
1: The photo doesn't show all that much detail
2: The bird is a juvenile.
3: It is a migratory raptor, and thus some range maps don't show it inhabiting Wisconsin
4: There are three different subspecies of this bird in the US, and they don't all look the same,
     4.5: and this guy/gal is not of the most common subspecies.

We had some guesses of Northern Harrier, which isn't half bad since this bird's color, speckling, and banded tail match that of a female Circus cyaneus. It's in the right habitat and location, too. It's even the right size. But it's not a harrier. I'll walk you through the identification:
Everyone seemed to get that it was a bird of prey based on its size and shape. After that, the most important identification feature of this bird is the face. Notice the really dark vertical stripe below the eye and the large white patch behind it. Harriers don't have facial patters as bold as that. That area of dark feathers is called a malar or moustachial stripe. This feature rules out all of the North American raptors except for falcons. Based on its size (approximated by comparing it to the cormorants) it has to be either Prairie, Peregrine, or Gyrfalcon. A gyr would be too dark and would not show up in Wisconsin unless it was a really bad winter and there wasn't enough food up north. This bird's color points towards Prairie Falcon... BUT WAIT!
The malar stripe is too large and dark for Prairie Falcon. And what would it be doing in the middle of a huge marsh? They eat mainly ground squirrels--which you aren't likely to find swimming. Horicon Marsh has lots and lots of waterfowl, which are perfect food for...
Peregrine Falcons!
Yup, this bird belongs to the fastest species on the planet. To be specific, this is a juvenile of the subspecies Falco peregrinus tundrius who was migrating south for the winter and happened to stop by in Wisconsin.

Okay, after all that... We move on to Round Three!!!

It's two species again, but this time you only have until October 15th to identify both... so start now!
This pair was spending their Spring Break in a tidal marsh in South Padre Island, TX. Once again, you can use "view image" to see it full size.

Have fun!
