Juvenile Raptor Identified

Dec16

Thank you all for your comments on my yard hawk!

The juvenile Cooper’s/Sharp-shinned conundrum is one of the greatest challenges in bird watching. The species are so similar that often a positive ID cannot be made when you see the bird for just a few minutes. In the winter months, you can add juvenile Northern Goshawk to the possibilities as well. With the additional help of photographs that can be pored over, feather by feather, it then becomes a matter of working your way through the bird guides.

I write for three different bird blogs, and when I was lucky enough to capture this beautiful hawk in pictures, I posted to all three, leaving the identification up to the readers. Guesses included Merlin, Swainson’s, Osprey, Cooper’s Hawk, Sharp-shinned and Northern Goshawk.

Consensus is…a Sharp-shinned hawk. Here are the reasons given.

  • Young sharpies have yellow eyes, while young Coopers have light yellow to almost pearly white eyes. Your bird has distinctly yellow eyes.
  • based on size, as compared to the shepherds hook and feeder, the bird seems Sharpie-sized
  • coarse brown streaks on the breast and belly
  • thinner legs than on a Cooper’s and narrow white tip on the tail feathers
  • smaller head and neck than a Cooper’s
  • pale eyebrow, narrow white tip on tail
  • Coopers have thicker white band on tail tip
  • Immature Cooper’s have whiter, more finely streaked breast
  • Sharpie’s have brown upper parts with white spots along scapulars
  • Cooper’s tend to have warmer brown napes, where yours has a darker nape
  • Sharp-shinned Hawk, based on the straight tail bars
  • wing-tips in relation to the length of the tail – Sharp-shinned Hawks wing-tips end just posterior to the hips.
  • undertail coverts on Goshawk have dark streaks

Now that I’ve gone through all this, I have absolutely no confidence that next time I see one of these birds, I’ll be able to identify it! They are just too tricky, but do provide a wonderful challenge for birdwatchers to tackle. However, I did find a fantastic website to help with the Cooper’s Hawk vs Sharp-shinned identification puzzle, so next time I’ll know where to look.

Juvenile Raptor Identification

Dec13

Do you like a birding challenge? This beautiful raptor visited my southeast Calgary yard late in November. I thought I would post these pictures without identifying the species, to give you a chance to test your raptor identification skills. Leave us a comment below, and tell us what you think it is.

This bird isn't injured, he's just wearing some of his lunch.

Tips on Bird Photography

Dec12

I think it is safe to say that most of us here have an interest in birdwatching. Some of us are also interested in photographing birds, documenting what we see and also enabling others to enjoy these sightings . Bird photography can be very tricky though and doesn’t always come out the way we want it to. Through trial and error as well as tips from other nature photographers, I have slowly learned different tricks of the trade and am still learning. Here is one trick that I have found helps me a lot.

Take a look at the picture above. Probably doesn’t do much for you, right? Just a killdeer photograph, nothing exciting about the shot itself. What could have been done to make this a better photograph? I have found that getting low can often drastically improve the photo. Get down at eye level with the bird, you can often create better eye contact with the bird, bringing the viewer into a connection with the photo. The Killdeer will then seem more interesting, not only because of the lower angle, but because of the  change in the depth of field of the shot.

Depth of field (also known as DOF), is the term for the amount of distance between the closest and farthest objects that appear sharp in the photograph. In the second picture above, a shallower depth of field (meaning a blurry background) makes the photo less distracting and more pleasing to the eye. In the photo pictured below, I took it one step further, instead of simply kneeling, I lay on my stomach, creating a very shallow depth of field and therefore, a picture that is more likely to catch your eye than the first photo.

Changing the depth of field is a remarkably simple technique but incredibly powerful in the way a photo comes out. By getting low, chances are you can improve your bird photography.

Sunday Showcase: Calgary Corvids

Dec4

Corvids, which are crows and jays, are classified by their harsh voices and their aggressive manner, both of which draw attention to themselves; large and often very gregarious birds. Most corvids have bristles on their nostrils, located on very powerful, all-purpose beaks built specially for handling their varied diet ( berries, fruits, seeds, invertebrates, small mammals and carrion). Here are most of the species that you may see in the Calgary region, the only one missing, is the colorful Steller’s Jay.

American Crow

Blue Jay

Grey Jay

Clark's Nutcracker
