Wednesday Wings: Northern Saw-whet Owl

Blog readers Elizabeth Sargent and Greg Earle sent us some absolutely stunning Northern Saw-whet Owl pictures that Greg took in Carburn Park. They visited on March 31, and were lucky enough to find this little guy at breast height in a thicket of bushes near the river. We’ve had a lot of great saw-whet owl photos on the blog in recent months, but these are just spectacular! Click to enlarge.

So you think you can dance?

Spring appears to be arriving a little early in Alberta this year, and as the snow begins to melt (well I guess the snow never really came this year, did it?), prairie birders will begin to head out in the early mornings with the hope of witnessing the impressive courtship dances of our prairie grouse. The charismatic Greater sage-grouse (Centrocercus urophasianus ) is recognized among naturalists for many reasons, but is perhaps best known for the spectacular courtship displays that occur on mating grounds (lek sites) each spring.

The greater sage-grouse is the largest of all North American grouse, and both males and females camouflage well in prairie grasses thanks to finely marked brown, black, and white feathers. Male sage-grouse can be distinguished by the presence of an arched yellow comb above the eye, long feathers behind the back of the neck, and a large white breast patch within which two large air sacs are concealed. The survival of the sage-grouse is intrinsically reliant upon the presence and abundance of silver sagebrush (Artemisia cana) flats, found in the Dry Mixedgrass subregion of the Grasslands natural region. This succulent shrub provides the bird’s food, shelter and cover from predators.

Each year, usually beginning in late March, hopeful male sage-grouse head to traditional lek sites where they may spend up to several weeks displaying for female hens. During this lively and intricate performance, males inflate and compress their air sacs producing loud popping sounds. This auditory experience, combined with the stunning visual of raised tail feathers and majestic strutting is indeed one to remember- or so I hear that is. And unfortunately, hearing tales and watching videos may be as close as many Albertans ever get to experiencing sage-grouse mating displays first hand.

Throughout the last decade, the reputation of the sage-grouse has grown for reasons besides being the Casanova of Alberta’s grasslands; the greater sage-grouse is also the most endangered species in Alberta. The sage-grouse was designated an At Risk species in Alberta in 1996 (downgraded to Endangered in 2000), and was recognized by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) as a federally Endangered species in 1998. Yet, it is now 2012 and neither provincial nor federal governments have taken any meaningful action to protect the sage-grouse or the habitat upon which its survival depends. Last spring, only 13 male sage-grouse were recorded on leks in Alberta. In neighbouring Saskatchewan, the only other Canadian province in which sage-grouse exist, populations are only slightly higher. These dismal counts represent an almost 90 percent population decline in Canada between 1988 and 2006.

It is clear that, like with most threatened and endangered species worldwide, this rapid decline can be attributed to habitat destruction and fragmentation. Degradation of native grasslands in southern Alberta due to urban expansion, cultivation, livestock grazing, and oil and gas exploration have left only approximately 43% of our grasslands remaining. Although 70% of the species at risk in the province reside in the grasslands, less than 1% is currently protected. In Alberta, sage-grouse can now be found only in the extreme southeast corner of the province, primarily surrounding the town of Manyberries, Alberta.

Sage-grouse are notoriously sensitive to disturbance, and studies have shown that, when confronted with oil and gas development, sage-grouse will abandon or avoid leks essential to their survival. Extensive energy development in southern Alberta has essentially impacted all remaining sage-grouse habitat.

Currently provincial species at risk are, sloppily, handled under the Alberta Wildlife Act. This piece of legislation does not require any mandatory actions to protect species at risk, besides the production of a provincial recovery plan. Since the Alberta Greater Sage-Grouse Recovery Plan was produced in 2005, populations have only continued to plummet. In light of this, we are relying upon provisions within the federal Species at Risk Act (SARA) that state the federal Environment Minister has a mandatory duty to make recommendations to protect a species facing imminent threat of extinction. The environmental law group Ecojustice is currently representing Alberta Wilderness Association (AWA), and several other conservation groups as we pursue legal action against Environment Minister Peter Kent over his continued failure to protect Canada’s endangered greater sage-grouse. In order to prevent the imminent extinction of this prairie icon, the critical habitat necessary to sage-grouse survival and recovery must be protected through legislation. Sage-grouse require a buffer of at least 1.9 km around all nesting, brood-rearing and winter habitat, and a 6.4 km buffer around all lek sites. Within this buffer zone all industrial activity must be prohibited, and existing industrial infrastructure must be removed.

Perhaps the single most frustrating, but also encouraging, piece of the sage-grouse puzzle is that the bird’s ecology and habitat requirements are well-understood. If we want to recover healthy sage-grouse populations in Alberta, it is entirely possible. But what we are obviously still missing is the desire and the political will to take the necessary steps before it is too late.

So I hope to leave you not with a bleak perspective on the state of species at risk in Alberta, but with an awareness of a truly remarkable species, and the desire to seek action from both federal and provincial levels of government to ensure the native grasslands of southern Alberta have not witnessed the sage-grouse’s last dance.

Spring has Sprung at Sikome Lake

Posted by Dan Arndt

 

It was quite evident by the bird activity last week at Carburn Park that spring would be arriving soon, and it became even more clear by the presence of two pairs of nesting Great Horned Owls at the East end of Fish Creek Provincial Park. One of our longest walks to date, at over 7km, we covered a huge amount of ground and saw some amazing sights.

Meeting at Bow Valley Ranch, we headed along the hillside on the north edge of the lot to attempt to find a Ring-necked Pheasant which had been seen and heard just before my arrival, but to no avail. Heading southward towards the creek, we found the first male Great Horned Owl guarding a nest, and female, that remained undiscovered by our group. A success in the eyes of any parenting owl, but it would be a great find in a month or two once the eggs hatch and babies begin to fledge, and even moreso if someone were there to get some photos! On the other hand, a well hidden nest keeps away those who wouldn’t treat it with the proper respect.

As we headed across the road through the park, and further south, we were constantly serenaded by the drumming and calling of the incredibly numerous Northern Flickers and Downy Woodpeckers in the area, both of which numbered at least twenty individuals through the course of our walk.

One of the most common questions of the day was, quite honestly, not surprising. With the incredible numbers of European Starlings coming in, many of those on our walk simply had no idea just how wide the range of Starling vocalizations truly was, and almost every variation of their call drew at least one question of “What bird made that call?”  To which my answer usually was: “This one.”

European Starling

The scourge of those who bird by ear.

We headed toward the south end of the park, and stopped briefly by the river to see if there were any unusual birds on the ice, on the shores, or in the water, but surprisingly, there were very few waterfowl at all on the Bow River. Directly on the river were a few Mallards, and on one pond just to the west, a few more Mallards and a pair of Common Goldeneye.

Turning back towards Sikome Lake, we came across the second pair of Great Horned Owls. The male appeared slightly agitated, and as we approached, actually flew closer to the nest to better guard it. It also appeared that this pair was much better known, as there were quite a few others viewing the pair as well. The female, though well hidden, was barely visible sitting atop the clutch of eggs.

Not too far away from this pair was another alert parent guarding his potential offspring. I wonder how many of his offspring will help feed the developing owlets in the coming months.

After stopping to watch this Canada Goose for a bit, we headed back north towards the vehicles, but first stopped to see just a few more woodpeckers in action. Both the Downy and Hairy Woodpeckers in this part of the part are incredibly tolerant to people walking only a few meters away.

And with that, we headed back to the vehicles, and home. It’s quite an exciting time here during spring migration, and one of the things every birder looks forward to with great anticipation. What will the coming week bring?  I suppose I’ll just have to wait until next Sunday to find out!
