Sunday Showcase: Golden Eagle

Have you ever wondered how the Golden Eagle got its name? These outstanding photos  from Paul Turbitt answer that question. Paul took these  juvenile eagle pictures at The Ann & Sandy Cross Conservation Area (ASCCA) just south of Calgary. If you haven’t visited this magical place, put in on your to-do list!

The ASCCA is open to the public, but visitors must make a booking online prior to their visit. Upon arrival, you must also register at the kiosk and pay the $2/person user fee.

Wednesday Wings: Bathing Merlin

If you’ve taken any pictures of interesting birds in the Calgary region, you can share them with us by emailing birdscalgary@gmail.com and we may post them on the blog.

Dave Arnold took these great shots of a Merlin having his Sunday bath on the edge of the Bow River.  Thanks for sharing, Dave!

Ian Chatt also witnessed this and got these three photos:

Another Sharp-shinned Hawk

Recently both Pat and Dan have posted about Sharp-shinned Hawks in their yard.  Now it’s my turn.  Last week we had our first ever accipiter in our SE Calgary yard, a juvenile Sharp-shinned Hawk that stopped here briefly.

It took me a while to figure out whether it was a Sharp-shinned or Cooper’s Hawk, but it actually is almost identical to the one Pat posted about here and here, and which was identified as a juvenile Sharp-shinned.  The bird that Dan saw was an adult, and you can read about it here.

The hawk was followed by about forty Black-billed Magpies, but they didn’t mob it.  While it sat on our fence, they just kept their distance in a nearby poplar.  But when the hawk left, they followed.

About twenty of the magpies that were following the hawk.

Unlike Dan’s hawk, my bird didn’t take any of the hundred or so small birds that were around my feeders at the time.  It just rested on the fence for three or four minutes, then flew off, and I haven’t seen it again.

Gus Yaki saw these pictures and said that he believes he has seen this same individual several times this autumn and winter in Fish Creek Park and along the Bow River.  It is distinctive because of the prominent white tips to the back feathers, which is unusual in this species.

It was certainly exciting to see this bird, even if it was only for a few minutes, and it’s one more species for the yard list.

Postcards from Texas: Vultures

When large metropolis’ coincide with wildlife and nature, there is invariably accidents. These accidents usually end up with nature coming out on the losing end. Nature sometimes benefits as well though. Sometimes, nature can adapt to the hustle and bustle of human living and actually benefit and thrive from this. Such is the way with vultures.

The other day, I was walking along a bayou here in Houston when I spotted a black clump in the grass not too far ahead.

This clump was a group of black vultures, 6 in total, with 9 more hanging around in the surrounding area. This meant that they must have found a dead animal and that they were feasting on it. This animal was roadkill, an unfortunate victim of our hustling and bustling. As mentioned before though, some creatures, such as vultures, benefit from this. The black vultures didn’t stick around very long and as soon as they saw me they flew away.

The black vulture does not have as good scent as the Turkey Vulture and tends, therefore, to follow Turkey vultures to carcasses where they proceed to drive the Turkey Vultures away from the meal. As soon as the Black Vultures saw me and flew away, the Turkey Vultures came in for their share.

When they came in, I started to creep closer and closer, not only for a better look, but also out of curiosity of what roadkill they were eating. While I moved somewhat stealthily closer, one vulture unfurled it’s wings and gave me good looks at it’s impressive 1.8 meter wingspan.

That wingspan is roughly 5 feet, 11 inches, which is well over half a foot taller than I am! I continued to crawl in closer until I was incredibly close.

I then found out what it was the vultures were eating…

And it was…

An opossum, as you might be able to tell by the foot in this photo. I feel bad for the poor guy… Some interesting bird behavior to see though, especially the hierarchy of vultures, where Black Vultures are not as skilled but are instead big bullies, chasing away Turkey Vultures from the food that the latter found.  I also took a photo in which I really saw why Turkey Vultures are called what they are

Doesn’t he just look like a turkey!?!

Falcon Identification

We received some absolutely stunning, stupendous photos of a falcon from Jim Walling. These were taken on Dec 30, mid afternoon along the Bow River at the Inglewood Bird Sanctuary. He only managed to capture these three shots before the bird was gone.

Two of us here at the blog identified it as a Prairie Falcon, based on the moustachial line and the dark bar on the wing lining. However, neither of us have even seen a Prairie Falcon that is this light in colour. Some web research turned up a number of similar pictures of a Saker Falcon, a European bird used in the art of falconry.

Do we have any falconers reading this blog?! Or is this an unusually white Prairie Falcon? Your comments, please!

Update January 9

What a dearth of comments on this bird. None of us are confident enough in our raptor ID to take a stand, but fortunately we have birding experts to give us a hand. Gus Yaki said this is a second year Prairie Falcon, and Gord Court also said this is a juvenile Prairie Falcon. Firm identification, for sure!

Schoolyard Swainson’s

Last July, right before I moved to Texas, I was treated to an incredible sight: a dark-morph Swainson’s Hawk perched on a fence in a school parking lot. This hawk was incredibly close to the sidewalk and allowed for some great photos, all the while sitting calmly on its perch.

 This hawk didn’t seem to be injured, it just seemed to be very tolerant of people. Supposedly, Swainson’s Hawks are accepting of human activity and tolerate even more in areas where this activity is more frequent. This species will often become accustomed to disturbance from humans, thus the higher level of tolerability. This hawk, however did still seem to be giving me the evil eye!

After a couple minutes, the impressive raptor, slowly turned away (above) and resumed its activities as if I wasn’t even there.

This is not the first time this year that a Swainson’s Hawk has allowed me to get very close to it, back in May, while we bloggers were doing the Big Sit, we observed a Swainson’s that allowed us to watch it from merely several feet away http://birdscalgary.wordpress.com/2011/05/15/swainsons-hawk/.

This was definitely one of the cooler birding parts of the summer!

It’s good to be back…

I flew in to Calgary from Houston last Friday night and was greeted by snow on the ground! Something that I haven’t seen since April. Never thought that I would be so excited to see snow. My first day back, Saturday, I took a walk around my neighborhood and was fortunate enough to see most of the locals; no not the neighbors, the birds.

First thing in the morning, I woke to see several Black-billed Magpies jumping and hollering about in the willow. Several Common Ravens flew overhead and 2 pairs of Chickadees visited the feeders. I was very happy to see the Black-capped Chickadees, nothing can compare with this species’ friendliness!

I have been following the reports from Albertabird still and I have seen all the reports of winter finches; I knew what a good year it was for these birds. I just didn’t know how good! In my hour or so walk, I saw more Crossbills then I did all last winter. I must have seen more than 100 crossbills!

Most of the crossbills were White-winged however there were a few Red Crossbills in the mix ( see photo above). I also observed many Pine Siskins that were flocking with the crossbills and feeding on the abundant cones.

My neighborhood, for some reason, never seems to be popular with Common Redpolls, however this year, within my first 24 hours of being back in Calgary, I had already seen 2 in my community. Also, we hosted a Pine Grosbeak, which is unusual for us. At one point, I was privileged to see several crossbills, a redpoll and many siskins on the ground just feet in front of me, licking up some sort of salt or rock from the ground.

Then, later on in the day, I discovered why my feeders were so empty. Three Sharp-shinned Hawks were all together in a tree. When 3 raptors start calling your neighborhood home, there are definitely going to be some songbird declines.

All in all, it’s good to be back!

Juvenile Raptor Identified

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

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.
